Summary of Changes Summary of Changes The information below summarizes the changes to this manual since the last printing as Publication 1761-6.2—October 1997. To help you find new information and updated information in this release of the manual, we have included change bars as shown to the right of this paragraph.
Chapter 1 Installing Your Controller This chapter shows you how to install your MicroLogix 1000 Programmable Controller. The only tools you require are a Flat head or Phillips head screwdriver and drill.
Chapter 1 Installing Your Controller Hardware Overview The MicroLogix 1000 programmable controller is a packaged controller containing a power supply, input circuits, output circuits, and a processor. The controller is available in 10 I/O, 16 I/O and 32 I/O configurations, as well as an analog version with 20 discrete I/O and 5 analog I/O.
Chapter 1 Installing Your Controller Master Control Relay A hard-wired master control relay (MCR) provides a reliable means for emergency controller shutdown. Since the master control relay allows the placement of several emergency-stop switches in different locations, its installation is important from a safety standpoint. Overtravel limit switches or mushroom head push buttons are wired in series so that when any of them opens, the master control relay is de-energized.
Chapter 1 Installing Your Controller Using Emergency-Stop Switches When using emergency-stop switches, adhere to the following points: • Do not program emergency-stop switches in the controller program. Any emergency-stop switch should turn off all machine power by turning off the master control relay. • Observe all applicable local codes concerning the placement and labeling of emergency-stop switches. • Install emergency-stop switches and the master control relay in your system.

Chapter 1 Installing Your Controller Using Surge Suppressors Inductive load devices such as motor starters and solenoids require the use of some type of surge suppression to protect the controller output contacts. Switching inductive loads without surge suppression can significantly reduce the lifetime of relay contacts. By adding a suppression device directly across the coil of an inductive device, you will prolong the life of the switch contacts.
Chapter 1 Installing Your Controller Suitable surge suppression methods for inductive ac load devices include a varistor, an RC network, or an Allen-Bradley surge suppressor, all shown below. These components must be appropriately rated to suppress the switching transient characteristic of the particular inductive device. See the table on page 1–9 for recommended suppressors.
Chapter 1 Installing Your Controller Recommended Surge Suppressors We recommend the Allen-Bradley surge suppressors shown in the following table for use with Allen-Bradley relays, contactors, and starters.
Chapter 1 Installing Your Controller ! ATTENTION: Explosion Hazard — Do not connect or disconnect while circuit is live unless area is known to be non-hazardous. Safety Circuits Circuits installed on the machine for safety reasons, like overtravel limit switches, stop push buttons, and interlocks, should always be hard-wired directly to the master control relay.
Chapter 1 Installing Your Controller Power Supply Inrush The MicroLogix power supply does not require or need a high inrush current. However, if the power source can supply a high inrush current, the MicroLogix power supply will accept it. There is a high level of inrush current when a large capacitor on the input of the MicroLogix is charged up quickly. If the power source cannot supply high inrush current, the only effect is that the MicroLogix input capacitor charges up more slowly.
Chapter 1 Installing Your Controller Preventing Excessive Heat For most applications, normal convective cooling keeps the controller within the specified operating range. Ensure that the specified operating range is maintained. Proper spacing of components within an enclosure is usually sufficient for heat dissipation. In some applications, a substantial amount of heat is produced by other equipment inside or outside the enclosure.
Chapter 1 Installing Your Controller ! ATTENTION: Be careful of metal chips when drilling mounting holes for your controller. Drilled fragments that fall into the controller could cause damage. Do not drill holes above a mounted controller if the protective wrap is removed. Use only the following communication cables in Class I, Division 2 Hazardous Locations.
Chapter 1 Installing Your Controller To remove your controller from the DIN rail: 1. Place a screwdriver in the DIN rail latch at the bottom of the controller. 2. Holding the controller, pry downward on the latch until the controller is released from the DIN rail. Side View DIN Rail 20147 Using Mounting Screws To install your controller using mounting screws: Important: Leave the protective wrap attached until you are finished wiring the controller. 1. Use the mounting template from page A–8. 2.
Chapter 2 Wiring Your Controller This chapter explains how to wire your MicroLogix 1000 Programmable Controller. Topics include: • grounding guidelines • sinking and sourcing circuits • wiring recommendations • wiring diagrams, input voltage ranges, and output voltage ranges Grounding Guidelines In solid-state control systems, grounding helps limit the effects of noise due to electromagnetic interference (EMI). Use the heaviest wire gauge listed for wiring your controller with a maximum length of 152.
Chapter 2 Wiring Your Controller You must also provide an acceptable grounding path for each device in your application. For more information on proper grounding guidelines, see the Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1. ATTENTION: Remove the protective wrap before applying power to the controller. Failure to remove the wrap may cause the controller to overheat.

Chapter 6 Programming Overview This chapter explains how to use the MicroLogix 1000 HHP to program the micro controller.
Chapter 6 Programming Overview With the logic program entered into the controller, placing the controller in the Run mode initiates an operating cycle. The controller’s operating cycle consists of a series of operations performed sequentially and repeatedly, unless altered by your program logic. overhead input scan service comms program scan Operating Cycle output scan input scan – the time required for the controller to scan and read all input data; typically accomplished within µseconds.
Chapter 6 Programming Overview Understanding File Organization The micro controller provides control through the use of a program. Most of the operations you perform with the MicroLogix 1000 HHP involve the program and the two components created with it: program files and data files. Program Program Files Data Files (14 Maximum) (8 Maximum) Notes on terminology: The term program used in HHP displays is equivalent to the term processor file that may be used in some programming software packages.
Chapter 6 Programming Overview Program Files Program files contain controller information, the main program, interrupt subroutines, and any subroutine programs. These files are: • System Program (file 0) – This file contains various system related information and user-programmed information such as program name and password. • Reserved (file 1) – This file is reserved. • Main Program (file 2) – This file contains user-programmed instructions defining how the controller is to operate.
Chapter 6 Programming Overview Understanding How Programs are Stored and Accessed The micro controller uses two devices for storing programs: RAM and EEPROM. The RAM provides short-term storage (i.e., its data is lost on a power down), while the EEPROM provides long-term storage (i.e., its data is not lost on a power down). The diagram below shows how the memory is allocated in the micro controller’s processor.
Chapter 6 Programming Overview Normal Operation During normal operation, both the micro controller and the HHP access the program stored in the RAM. Any changes to retentive data that occur due to program execution or programming commands affect only the retentive data in the RAM. The program files are never modified during normal operation. However, both the CPU and the HHP can read the program files stored in RAM.
Chapter 6 Programming Overview Power Up During power up, the micro controller transfers the program files from the EEPROM to the RAM. The retentive data is also transferred to the RAM, provided it was not lost on power down, and normal operation begins. RAM EEPROM Backup Data Retentive Data Program Files CPU Workspace Retentive Data Program Files CPU If retentive data was lost on power down, the backup data from the EEPROM is transferred to the RAM and used as the retentive data.
Chapter 6 Programming Overview Specifying Logical Addresses You assign logical addresses to instructions from the highest level (element) to the lowest level (bit). Addressing examples are shown in the table below. To specify the address of a: Use these parameters:➀ Word within an integer file N 2 File Type Word Number Word within a structure file T 7 .
Chapter 6 Programming Overview Specifying Indexed Addresses The indexed address symbol is the # character, which is placed immediately before the file-type identifier in a logical address. You can use more than one indexed address in your ladder program. When you specify indexed addresses, follow these guidelines: • Make sure the index value (positive or negative) does not cause the indexed address to exceed the file type boundary.
Chapter 6 Programming Overview Addressing File Instructions – Using the File Indicator (#) The file instructions shown below manipulate data table files. These instructions are addressed with the # sign. They store an offset value in word S24 (index register), just as with indexed addressing discussed in the last section.
Chapter 6 Programming Overview When entering hexadecimal characters, you may need to access the following additional characters, not displayed on the keypad. To Access This Character: Press This Key Sequence: A FUN B F UN C FUN D FUN E FUN F FUN 7 8 9 4 5 6 You can change the radix for output, input, bit and integer data files. See page 18–30 for more information. Applying Logic to Your Schematics The program is made from the logic you enter into the micro controller.
Chapter 6 Programming Overview In a ladder diagram, each of the input devices are represented in series or parallel combinations across the rung of the ladder. The last element on the rung is the output that receives the action as a result of the conditional state of the inputs on the rung. Each output instruction is executed by the controller when the rung is scanned and the conditions on the rung are true.
Chapter 6 Programming Overview Input Branching Use an input branch in your application program to allow more than one combination of input conditions to form parallel branches (OR-logic conditions). If at least one of these parallel branches forms a true logic path, the rung logic is enabled. If none of the parallel branches forms a true logic path, rung logic is not enabled and the output instruction logic will not be true. The output is not energized.
Chapter 6 Programming Overview Connecting Blocks Blocks of input and output instructions can be connected in series and parallel as well. Example – Series Block Connection a c b d e In the above example, two blocks of information are connected in series. Either A or B, and C or D provides a true logical path. For instruction list programming, the ANB instruction represents this connection. (See page 8–12.
Chapter 6 Programming Overview Nested branching can be converted into non-nested branches by repeating instructions to make parallel equivalents. Example – Non-Nested Equivalent a b c f d e Nested branch a b C d c f e Non-nested equivalent parallel branch Understanding Instruction List Programs Instruction list (Boolean) programming uses mnemonics to represent all the functions and connections available in a ladder logic instruction set.
Chapter 6 Programming Overview Applying Ladder Logic and Instruction List In the following illustration, the electromechanical circuit shows PB1 and PB2, two push buttons, wired in series with an alarm horn. PB1 is a normally open push button and PB2 is normally closed. This same circuit is shown in ladder logic by two contacts wired in series with an output. Contact I/0 and I/1 are examine-if-closed instructions.➀ (For more information on this instruction, refer to page 8–3.
Chapter 6 Programming Overview Developing Your Logic Program – A Model The following diagram can help you develop your application program. Each process block represents one phase of program development. Use the checklist at the right of the process block to help you identify the tasks involved with each process.
Chapter 7 Using Analog This chapter describes the operation of the MicroLogix 1000 analog controllers. Topics include: • • • • I/O Image I/O Image I/O Configuration Input Filter and Update Times Converting Analog Data The input and output image files of the MicroLogix 1000 analog controllers have the following format: Address Input Image Output Image Address I:0.0 Discrete Input Word 0 Discrete Output Word 0 O:0.0 I:0.1 Discrete Input Word 1 Reserved O:0.1 I:0.2 Reserved Reserved O:0.
Chapter 7 Using Analog I/O Configuration The analog input channels are single-ended (unipolar) circuits and can be individually enabled or disabled. The default is all input channels enabled. The two voltage inputs accept"10.5V dc and the two current inputs accept "21 mA. The analog output channel is also a single-ended circuit. You can configure either voltage (0V dc to +10V dc) or current (+4 to +20 mA) output operation. The default is voltage output.
Chapter 7 Using Analog Update Time Examples Example 1 – All (4) channels enabled with 60 Hz filter selected (default settings). Maximum Update Time = (4) x ladder scan time + (4) x 16.67 ms + (4) x 66.67 ms = 333.36 ms + (4) x ladder scan times (Each channel is updated approximately three times per second.) Example 2 – 1 channel enabled with 250 Hz filter selected. Maximum Update Time = ladder scan time + 4 ms Input Channel Filtering The analog input channels incorporate on-board signal conditioning.
Chapter 7 Using Analog Converting Analog Data The analog input circuits are able to monitor current and voltage signals and convert them to digital data. There are six terminals assigned to the input channels that provide two voltage inputs, two current inputs, and two return signals (commons). The analog outputs can support either a current or voltage function. There are three terminals assigned to the output channels that provide one voltage output, one current output, and a common (shared) terminal.
Chapter 7 Using Analog To determine an approximate current that an input value represents, you can use the following equation: 21 mA input value➁ = input current (mA) 32,767 ➁The Input Value is the decimal value of the word in the input image for the corresponding analog input. For example, if an input value of 4096 is in the input image, the calculated value is: 21 mA 4096 = 2.625(mA) 32,767 It should be noted that the actual value may vary within the accuracy limitations of the module.
Chapter 8 Using Basic Instructions This chapter contains general information about basic instructions and explains how they function in your application program. Each of the basic instructions includes information on: • what the instruction symbol looks like • typical execution time for the instruction • how to use the instruction • how to enter the instruction In addition, the last section contains an application example for a paper drilling machine that shows the basic instructions in use.
Chapter 8 Using Basic Instructions Branch Instructions Mnemonic Function Code MPS Name Purpose Page 10 Memory Push Stores the rung state that is present immediately preceding the MPS instruction. 8–10 MRD 11 Memory Read Reads the rung state stored by the MPS instruction and resumes operation using that rung state. 8–10 MPP 12 Memory Pop Removes the rung state stored by the MPS instruction, reads it, and resumes operation using that rung state.
Chapter 8 Using Basic Instructions Bit Instructions Overview These instructions operate on a single bit of data. During operation, the controller may set or reset the bit, based on the logical continuity of the rung. You can address a bit as many times as your program requires. Important: Using the same address with multiple output instructions is not recommended. Bit instructions are used with the following data files: • Output (O) and input (I) data files. These represent external outputs and inputs.
Chapter 8 Using Basic Instructions Using AND Use the AND instruction for normally open contacts placed in series with any previous input instruction in the current rung or block. Entering the Instruction You enter the instruction from within the program monitor functional area. To access the AND instruction, press: AND 8 P 0 0 0 I / 7 0 Using OR Use the OR instruction for normally open contacts placed in parallel with any previous input instruction in the current rung or block.
Chapter 8 Using Basic Instructions Using LDI Use the LDI instruction for normally closed contacts that appears first on a rung or block. Entering the Instruction You enter the instruction from within the program monitor functional area. To access the LDI instruction, press: LDI 4 P 0 0 0 I / 6 / 0 Using ANI Use the ANI instruction for normally closed contacts placed in series with any previous input instruction in the current rung or block.
Chapter 8 Using Basic Instructions Load True (LDT) and Or True (ORT) Ladder representation: The LDT and ORT instructions are used to short circuit a block of logic. They are useful for debugging a rung when you need a condition that is always true. There are no parameters to enter for these instructions. LDT ] [ ] [ ORT Execution Times (µsec) when: True LDT 1.54 ORT 1.94 Using LDT False Use the LDT instruction to place a short in the first position of a rung or block.
Chapter 8 Using Basic Instructions One-Shot Rising (OSR) The OSR instruction is a retentive input instruction that triggers an event to occur one time. Use the OSR instruction when an event must start based on the change of state of the rung from false to true. Ladder representation: B3 [OSR] 0 True False When the rung conditions preceding the OSR instruction go from false to true, the OSR instruction becomes true for one scan.
Chapter 8 Using Basic Instructions Output (OUT) Use an OUT instruction in your ladder program to turn On a bit when rung conditions are evaluated as true. Ladder representation: An example of a device that turns on or off is an output wired to a pilot light (addressed as O/4). ( ) OUT instructions are reset when: • You enter or return to the RRUN, RCSN, or RSSN mode or power is restored. • The OUT is programmed within an inactive or false Master Control Reset (MCR) zone.
Chapter 8 Using Basic Instructions Using SET When you assign an address to the SET instruction that corresponds to the address of a physical output, the output device wired to this screw terminal is energized when the bit is set (turned on or latched). When rung conditions become false (after being true), the bit remains set and the corresponding output device remains energized. When enabled, the SET instruction tells the controller to turn on the addressed bit.
Chapter 8 Using Basic Instructions Memory Push (MPS), Memory Read (MRD), and Memory Pop (MPP) MPS, MRD, and MPP are multiple output circuit connecting instructions. These instructions work together to store, read, and clear the state of a rung prior to the execution of an output circuit. Every MPS instruction used in a program must be paired with an MPP instruction. An MRD instruction is not always required.
Chapter 8 Using Basic Instructions Using MRD The MRD instruction reads the rung state stored by the MPS instruction and resumes operation using that rung state. Each branch structure can have a maximum of 73 MRD instructions. This instruction can only be used if all of the following statements are true: • An MPS instruction was used previously on the rung. • The MRD is immediately preceded by an output instruction. • An output circuit immediately follows the MRD.
Chapter 8 Using Basic Instructions Entering the Instruction You enter the instruction from within the program monitor functional area. To enter the function code, press: P 0 0 0 FUN 1 L MP P ENT 2 The example below illustrates when you would enter the MPP instruction. b a c And Block (ANB) and Or Block (ORB) Ladder representation: ] [ ANB ] [ ] [ ] [ ] [ ] [ ] [ ] [ d e Instruction List NEW RUNG LD a OUT b MPS AND c OUT d MPP OUT e ANB and ORB are block connecting instructions.
Chapter 8 Using Basic Instructions The example below illustrates when you would enter the ANB instruction. a c b d e Instruction List NEW RUNG LD a OR b LD c OR d ANB OUT e Using ORB The ORB instruction is used to make a parallel connection of circuit blocks with two or more contacts. (A parallel connection of circuit blocks with one contact requires only an OR or ORI instruction. See page 16–2.) Entering the Instruction You enter the instruction from within the program monitor functional area.
Chapter 8 Using Basic Instructions Timer Instructions Overview Each timer address is made of a 3-word element. Word 0 is the control word, word 1 stores the preset value, and word 2 stores the accumulator value. 15 14 13 Word 0 EN TT DN Word 1 Preset Value Word 2 Accumulator Value Internal Use EN = Timer Enable Bit TT = Timer Timing Bit DN = Timer Done Bit Entering Parameters Accumulator Value (ACC) This is the time elapsed since the timer was last reset.
Chapter 8 Using Basic Instructions Entering the Instructions The following items apply when entering the instructions: • Whenever you see asterisks on the display, the HHP is waiting for data entry (i.e., a number). • If you see a down arrow on the display it means there are more options available. To scroll through the options, press this key: • You can return to previously entered operands by pressing this key: Then if you want to edit that operand, press DEL or FUN-DEL and enter new parameters.
Chapter 8 Using Basic Instructions Timer On-Delay (TON) Use the TON instruction to delay the turning on or off of an output. The TON instruction begins to count timebase intervals when rung conditions become true. As long as rung conditions remain true, the timer increments its accumulated value (ACC) each scan until it reaches the preset value (PRE). The accumulated value is reset when rung conditions go false, regardless of whether the timer has timed out.
Chapter 8 Using Basic Instructions Once instruction entry is complete, the parameters are condensed to two screens as shown here: P 0 0 0 T ON P 1 0 0 A P 0 0 0 0 . 0 1 T ON S E C T 0 0 6 6 B A S E When the controller changes from the RRUN, RCSN, or RSSN mode to the RPRG mode or user power is lost while the instruction is timing but has not reached its preset value, the following occurs: • Timer Enable (EN) bit remains set. • Timer Timing (TT) bit remains set.
Chapter 8 Using Basic Instructions Timer Off-Delay (TOF) Use the TOF instruction to delay turning on or off an output. The TOF instruction begins to count timebase intervals when the rung makes a true-to-false transition. As long as rung conditions remain false, the timer increments its accumulated value (ACC) each scan until it reaches the preset value (PRE). The controller resets the accumulated value when rung conditions go true regardless of whether the timer has timed out.
Chapter 8 Using Basic Instructions Once instruction entry is complete, the parameters are condensed to two screens as shown here: P 0 0 0 T OF P 1 2 0 A P 0 0 0 0 . 0 1 T OF S E C T 0 1 0 B A S E When the controller changes from the RRUN, RCSN, or RSSN mode to the RPRG mode, or user power is lost while a timer off-delay instruction is timing but has not reached its preset value, the following occurs: • Timer Enable (EN) bit remains set. • Timer Timing (TT) bit remains set.
Chapter 8 Using Basic Instructions Retentive Timer (RTO) Use the RTO instruction to turn an output on or off after its timer has been on for a preset time interval. The RTO instruction is a retentive instruction that lets the timer stop and start without resetting the accumulated value (ACC). Ladder representation: RTO RETENTIVE TIMER ON Timer T4:2 Time Base 0.01 Preset 120 Accum 0 (EN) (DN) Execution Times (µsec) when: True False 38.34 27.

Chapter 8 Using Basic Instructions Entering Parameters Accumulator Value (ACC) This is the number of false-to-true transitions that have occurred since the counter was last reset. Preset Value (PRE) Specifies the value which the counter must reach before the controller sets the done bit. When the accumulator value becomes equal to or greater than the preset value, the done status bit is set. You can use this bit to control an output device.
Chapter 8 Using Basic Instructions Addressing Structure Address bits and words using the format shown below. Format Ce.s/b C . /b Explanation C Counter file e Element number Ranges from 0 – 39. These are 3-word elements. See figure on page 8–21. . Subelement delimiter s Subelement / Bit delimiter b Bit number PRE or ACC Important: If assigned to a high-speed counter instruction, C0 is not available as an address for any other counter instructions.
Chapter 8 Using Basic Instructions How Counters Work The figure below demonstrates how a counter works. The count value must remain in the range of –32,768 to +32,767. If the count value goes above +32,767 or below –32,768, a counter status overflow (OV) or underflow (UN) bit is set. A counter can be reset to zero using the reset (RES) instruction. (See page 8–27.
Chapter 8 Using Basic Instructions Entering the Instruction You enter the instruction from within the program monitor functional area.
Chapter 8 Using Basic Instructions Using Status Bits This Bit Is Set When And Remains Set Until One of the Following Count Down Underflow Bit UN (bit 11) accumulated value wraps around to +32,768 (from –32,767) and continues counting down from there a RES instruction having the same address as the CTD instruction is enabled.
Chapter 8 Using Basic Instructions Reset (RES) Use a RES instruction to reset a timer or counter. When the RES instruction is executed, it resets the data having the same address as the RES instruction. Ladder representation: T4:0 (RES) Using a RES instruction for a: The controller resets the: Timer (Do not use a RES instruction with a TOF.
Chapter 8 Using Basic Instructions Basic Instructions in the Paper Drilling Machine Application Example To demonstrate the use of basic instructions, this section provides ladder rungs followed by the optimized instruction list for these rungs. The rungs are part of the paper drilling machine application example described in appendix D. You will be updating the main program in file 2 and adding a subroutine to file 6.
Chapter 8 Using Basic Instructions Ladder Rungs Rung 2:3➀ Starts the conveyor in motion when the start button is pressed. However, another condition must also be met before we start the conveyor: the drill must be in its fully retracted position (home). This rung also stops the conveyor when the stop button is pressed.
Chapter 8 Using Basic Instructions File 2, Rung 4 Applies the above start logic to the conveyor and drill motor.
Chapter 8 Using Basic Instructions Rung 6:1 When the drill has drilled through the book, the body of the drill actuates the DRILL DEPTH limit switch. When this happens, the DRILL FORWARD signal is turned off and the DRILL RETRACT signal is turned on. The drill is also retracted automatically on power up if it is not actuating the DRILL HOME limit switch.

Chapter 11 Using Data Handling Instructions Data Handling Instructions in the Paper Drilling Machine Application Example To demonstrate the use of data handling instructions, this section provides ladder rungs, followed by the optimized instruction list for these rungs. The rungs are part of the paper drilling machine application example described in appendix E. You will be adding to the subroutine in file 7 that was started in chapter 9.
Chapter 11 Using Data Handling Instructions Rung 7:4 Ensures that the operator cannot select a paper thickness of 0. If this were allowed, the drill bit life calculation could be defeated resulting in poor quality holes due to a dull drill bit. Therefore the minimum paper thickness used to calculate drill bit wear is 1/4 in.
Chapter 11 Using Data Handling Instructions File 7, Rung 3 Converts the BCD thumbwheel value from BCD to integer. This is done because the controller operates upon integer values. This rung also ”debounces” the thumbwheel to ensure that the conversion only occurs on valid BCD values. Note that invalid BCD values can occur while the operator is changing the BCD thumbwheel. This is due to input filter propagation delay differences between the four input circuits that provide the BCD input value.
Chapter 12 Using Program Flow Control Instructions This chapter contains general information about the program flow instructions and explains how they function in your application program.
Chapter 12 Using Program Flow Control Instructions Jump (JMP) and Label (LBL) Use these instructions in pairs to skip portions of the ladder program. If the Rung Containing the Jump Instruction is: True Ladder representation: 2 (JMP) False 2 ]LBL[ 9.04 1.45 Skips from the rung containing the JMP instruction to the rung containing the designated LBL instruction and then continues executing. You can jump forward or backward. Does not execute the JMP instruction.
Chapter 12 Using Program Flow Control Instructions You can program multiple jumps to the same label by assigning the same label number to multiple JMP instructions. However, label numbers must be unique. Important: Do not jump (JMP) into an MCR zone. Instructions that are programmed within the MCR zone starting at the LBL instruction and ending at the ‘END MCR’ instruction are always evaluated as though the MCR zone is true, regardless of the true state of the “Start MCR” instruction.
Chapter 12 Using Program Flow Control Instructions Nesting Subroutine Files Nesting subroutines allows you to direct program flow from the main program to a subroutine and then on to another subroutine. You can nest up to eight levels of subroutines. If you are using an STI subroutine, HSC interrupt subroutine, or user fault routine, you can nest subroutines up to three levels from each subroutine. The following figure illustrates how subroutines may be nested.
Chapter 12 Using Program Flow Control Instructions Using SBR The target subroutine is identified by the file number that you entered in the JSR instruction. This instruction serves as a label or identifier for a program file as a regular subroutine file. This instruction has no control bits. It is always evaluated as true. Use of this instruction is optional; however, we recommend using it for clarity. Important: The instruction must be programmed as the first instruction of the first rung of a subroutine.
Chapter 12 Using Program Flow Control Instructions Master Control Reset (MCR) Ladder representation: (MCR) Use MCR instructions in pairs to create program zones that turn off all the non-retentive outputs in the zone. Rungs within the MCR zone are still scanned, but scan time is reduced due to the false state of non-retentive outputs. Non-retentive outputs are reset when their rung goes false. If the MCR Rung that Starts the Zone is: Execution Times (µsec) when: True False 3.98 4.
Chapter 12 Using Program Flow Control Instructions Temporary End (TND) This instruction, when its rung is true, stops the controller from scanning the rest of the program file, updates the I/O, and resumes scanning at rung 0 of the main program (file 2). If this instruction’s rung is false, the controller continues the scan until the next TND instruction or the END statement.

If you address it as a file (using file indicator #), the instruction automatically steps through the source, mask, or destination file.
Chapter 13 Using Application Specific Instructions The done bit is set when the last word of the sequencer file is transferred. On the next false-to-true rung transition, the instruction resets the position to step one. If the position is equal to zero at startup, when you switch the controller from the RPRG mode to the RRUN mode, instruction operation depends on whether the rung is true or false on the first scan. • If true, the instruction transfers the value in step zero.
Chapter 13 Using Application Specific Instructions Operation The operation of the SQO instruction is shown in the figure below. The screens shown above the figure are the condensed screens that appear after instruction entry is complete.
Chapter 13 Using Application Specific Instructions Using SQC When the status of all non-masked bits in the source word match those of the corresponding reference word, the instruction sets the found bit (FD) in the control word. Otherwise, the found bit (FD) is cleared. The bits mask data when reset and pass data when set. The mask can be fixed or variable. If you enter a hexadecimal code, it is fixed. If you enter an element address or a file address for changing the mask with each step, it is variable.
Chapter 13 Using Application Specific Instructions Operation The operation of the SQC instruction is shown in the figure below. The screens shown above the figure are the condensed screens that appear after instruction entry is complete.
Chapter 13 Using Application Specific Instructions Sequencer Load (SQL) Ladder representation: The SQL instruction stores 16-bit data into a sequencer load file at each step of sequencer operation. The source of this data can be an I/O or internal word address, a file address, or a constant. SQL SEQUENCER LOAD File #B3:8 Source I:0.0 Control R6:3 Length 4 Position 2 Execution Times (µsec) when: True False 53.41 28.
Chapter 13 Using Application Specific Instructions Entering the Instruction You enter the instruction from within the program monitor functional area.
Chapter 13 Using Application Specific Instructions Operation The operation of the SQL instruction is shown in the figure below. The screens shown above the figure are the condensed screens that appear after instruction entry is complete. Input word I0 is the source. Data in this word is loaded into integer file #N30 by the sequencer load instruction.
Chapter 13 Using Application Specific Instructions Selectable Timed Interrupt (STI) Function Overview The Selectable Timed Interrupt (STI) function allows you to interrupt the scan of the application program automatically, on a periodic basis, to scan a subroutine file. Afterwards, the controller resumes executing the application program from the point where it was interrupted. Basic Programming Procedure for the STI Function To use the STI function in your application file: 1.
Chapter 13 Using Application Specific Instructions JSR stack depth is limited to three. You may call other subroutines to a level three deep from an STI subroutine. Interrupt Latency and Interrupt Occurrences Interrupt latency is the interval between the STI timeout and the start of the interrupt subroutine. STI interrupts can occur at any point in your program, but not necessarily at the same point on successive interrupts.
Chapter 13 Using Application Specific Instructions Selectable Timed Disable (STD) and Enable (STE) These instructions are generally used in pairs. The purpose is to create zones in which STI interrupts cannot occur. Ladder representation: STD SELECTABLE TIMED DISABLE Using STD STE When true, this instruction resets the STI enable bit and prevents the STI subroutine from executing. When the rung goes false, the STI enable bit remains reset until a true STS or STE instruction is executed.
Chapter 13 Using Application Specific Instructions The first pass bit S1/15 and the STE instruction in rung 0 are included to insure that the STI function is initialized following a power cycle. You should include this rung any time your program contains an STD/STE zone or an STD instruction. Program File 3 0 S:1 ] [ 15 1 ] [ STE SELECTABLE TIMED ENABLE ( ) ] [ 2 3 4 5 STD SELECTABLE TIMED DISABLE 6 STI interrupt execution will not occur between STD and STE.
Chapter 13 Using Application Specific Instructions Entering the Instruction You enter the instructions from within the program monitor functional area. The following items apply when entering the instructions: • Whenever you see asterisks on the display, the HHP is waiting for data entry (i.e., a number). • You can return to previously entered operands by pressing this key: Then if you want to edit that operand, press DEL or FUN-DEL and enter new parameters.
Chapter 13 Using Application Specific Instructions Application Specific Instructions in the Paper Drilling Machine Application Example To demonstrate the use of application specific instructions, this section provides ladder rungs followed by the optimized instruction list of these rungs. The rungs are part of the paper drilling machine application example described in appendix E. You will begin a subroutine in file 4.
Chapter 13 Using Application Specific Instructions Ladder Rungs Rung 4:0 Resets the hole count sequencers each time the low preset is reached. The low preset has been set to zero to cause an interrupt to occur each time that a reset occurs. The low preset is reached anytime that a reset C5:0 or hardware reset occurs. This ensures that the first preset value is loaded into the HSC at each entry into the RRUN mode and each time that the external reset signal is activated.
Chapter 13 Using Application Specific Instructions Rung 4:2 Is identical to the previous rung except that it is only active when the ”hole selector switch” is in the ”5–hole” position.
Chapter 13 Using Application Specific Instructions Instruction List File 4, Rung 0 Resets the hole count sequencers each time that the low preset is reached. The low preset has been set to zero to cause an interrupt to occur each time that a reset occurs. The low preset is reached anytime that a reset C5:0 or hardware reset occurs. This ensures that the first preset value is loaded into the high–speed counter at each entry into the RRUN mode and each time that the external reset signal is activated.
Chapter 13 Using Application Specific Instructions File 4, Rung 2 Is identical to the previous rung except that it is only active when the ”hole selector switch” is in the ”5–hole” position.
Chapter 14 Using High-Speed Counter Instructions This chapter contains general information about the high-speed counter instructions and explains how they function in your application program.
Chapter 14 Using High-Speed Counter Instructions High-Speed Counter Instructions Overview Use the high-speed counter instructions to perform specific actions after a preset count is reached. These actions include the automatic and immediate execution of the high-speed counter interrupt routine (file 4) and the immediate update of outputs based on a source and mask pattern you set. Counter Data File Elements The high-speed counter instructions reference counter C0. The HSC instruction is fixed at C0.
Chapter 14 Using High-Speed Counter Instructions • Overflow Occurred Bit OV (bit 12) For the Up Counters (modes 1 and 2), this bit is set by the controller when the high preset is reached if the DN bit is set. Tip For the Bidirectional Counters (modes 3–8), the OV bit is set by the controller after the hardware accumulator transitions from 32,767 to –32,768. You can reset this bit with an OTU instruction or by executing an RAC or RES instruction for both the up and bidirectional counters.
Chapter 14 Using High-Speed Counter Instructions • High Preset Reached Caused User Interrupt Bit IH (bit 5) is set to • • • • High-Speed Counter (HSC) Ladder representation: HSC HIGH SPEED COUNTER Type Up (Res,Hld) Counter C5:0 High Preset 1 Accum 1 Execution Times (µsec) when: True False 21.00 21.00 (CU) (CD) (DN) identify a high preset reached as the cause for the execution of the high-speed counter interrupt routine. The IV, IN, and IL bits are reset by the controller when the IH bit is set.
Chapter 14 Using High-Speed Counter Instructions The table that follows uses the terminology shown here to indicate the status of counting: • Up↑ – increments by 1 when the input energizes (edge). • Down↑ – decrements by 1 when the input energizes (edge). • Reset↑ – resets the accumulator to zero when the input energizes (edge). • Hold – disables the high-speed counter from counting while the input is energized (level). • Count – increments or decrements by 1 when the input energizes (edge).
Chapter 14 Using High-Speed Counter Instructions Entering the Instruction You enter the instruction from within the program monitor functional area. The following items apply when entering the instruction: • Whenever you see asterisks on the display, the HHP is waiting for data entry (i.e., a number). • If you see a down arrow on the display it means there are more options available.
Chapter 14 Using High-Speed Counter Instructions Once instruction entry is complete, the parameters are condensed to two screens as shown here: P 0 0 8 H S C U P R E S / H L D P 0 0 8 P H S C 1 A T Y P E C 0 0 – 1 Using the Up Counter and the Up Counter with Reset and Hold Up counters are used when the parameter being measured is uni-directional, such as material being fed into a machine or as a tachometer recording the number of pulses over a given time period.
Chapter 14 Using High-Speed Counter Instructions When a high preset is reached, no counts are lost. • Hardware and instruction accumulators are reset. • Instruction high preset is loaded to the hardware high preset. • If the DN bit is not set, the DN bit is set. The IH bit is also set and the IL, IV, and IN bits are reset. • If the DN bit is already set, the OV bit is set. The IV bit is also set and the IL, IV and IN bits are reset.
Chapter 14 Using High-Speed Counter Instructions Using the Bidirectional Counter and the Bidirectional Counter with Reset and Hold Bidirectional counters are used when the parameter being measured can either increment or decrement. For example, a package entering and leaving a storage bin is counted to regulate flow through the area. The Bidirectional Counters operate identically except for the operation of inputs 1 and 0.
Chapter 14 Using High-Speed Counter Instructions When a high preset is reached, the: • HP bit is set. • High-speed counter interrupt file (file 4) is executed if the interrupt is enabled. The IH bit is set and the IL, IV, and IN bits are reset. Unlike the Up Counters, the accumulator value is not reset and the high preset value is not loaded from the image to the hardware high preset register.

Chapter 14 Using High-Speed Counter Instructions When up and down input pulses occur simultaneously, the high-speed counter counts up, then down. Using the Bidirectional Counter with Reset and Hold with a Quadrature Encoder The Quadrature Encoder is used for determining direction of rotation and position for rotating, such as a lathe. The Bidirectional Counter counts the rotation of the Quadrature Encoder.
Chapter 14 Using High-Speed Counter Instructions Operation For the Bidirectional Counters, both high and low presets are used. The low preset value must be less than the high preset value or an error (37H) occurs. When the HSC instruction is first executed true, the: • Instruction accumulator is loaded to the hardware accumulator. • Instruction high preset is loaded to the hardware high preset. Any instruction accumulator value between –32,768 and +32,767 inclusive can be loaded to the hardware.
Chapter 14 Using High-Speed Counter Instructions When a low preset is reached, the: • LP bit is set. • High-speed counter interrupt file (file 4) is executed if the interrupt is enabled. The IL bit is set and the IH, IN, and IV bits are reset. An overflow occurs when the hardware accumulator transitions from +32,767 to –32,768. When an overflow occurs, the: • OV bit is set. • High-speed counter interrupt file (file 4) is executed if the interrupt is enabled.
Chapter 14 Using High-Speed Counter Instructions High-Speed Counter Load (HSL) Ladder representation: HSL HSC LOAD Counter Source Length C5:0 N7:5 5 (CU) (DN) This instruction allows you to set the low and high presets, low and high output source, and the output mask. When either a high or low preset is reached, you can instantly update selected outputs. If you are using the HSL instruction with the Up Counter, the high preset must be ≥ 1 and ≤ +32,767 or an error (37H) occurs.
Chapter 14 Using High-Speed Counter Instructions To enter the function code, press: FUN 1 7 1 ENT P 0 0 8 C 0 0 H S L C N T R P 0 0 8 N 5 H S L S R C P 0 0 8 H S L 0 L E N 5 Operation The HSL instruction allows you to configure the high-speed counter to instantaneously and automatically update external outputs whenever a high or low preset is reached. The physical outputs are automatically updated in less than 30 µs. (The physical turn-on time of the outputs is not included in this amount.
Chapter 14 Using High-Speed Counter Instructions Parameter Image Location Up Counter Only Bidirectional Counters Description N5 Output Mask Output Mask Identifies which group of four bits in the output file (word 0) are controlled. 000F=bits 3–0 00F0=bits 7–4 0003=bits 0 and 1 00FF= bits 7–0 N6 Output Source Output High Source (Up count) The status of bits in this word are written “through” the mask to the actual outputs.
Chapter 14 Using High-Speed Counter Instructions If a fault occurs due to the HSL instruction, the HSL parameters are not loaded to the high-speed counter hardware. You can use more than one HSL instruction in your program. The HSL instructions can have different image locations for the additional parameters. ! ATTENTION: Do not change a preset value and an output mask/source with the same HSL instruction as the accumulator is approaching the old preset value.
Chapter 14 Using High-Speed Counter Instructions High-Speed Counter Reset (RES) The RES instruction allows you to write a zero to the hardware accumulator and image accumulator. Ladder representation: The Counter referenced by this instruction has the same address as the HSC instruction counter and is entered as C0. C5:0 RES) ) Execution Times (µsec) when: True False 51.00 6.00 Entering the Instruction You enter the instruction from within the program monitor functional area.
Chapter 14 Using High-Speed Counter Instructions High-Speed Counter Reset Accumulator (RAC) This instruction allows you to write a specific value to the hardware accumulator and image accumulator. Ladder representation: The Counter referenced by this instruction has the same address as the HSC instruction counter and is fixed at C0.
Chapter 14 Using High-Speed Counter Instructions Operation Execution of the RAC: • removes pending high-speed counter interrupts • resets the PE, LS, OV, UN, and DN status bits • loads a new accumulator value to the hardware and instruction image • loads the instruction high preset to the hardware high preset (if the high-speed counter is configured as an Up Counter) • resets the IL, IH, IN, or IV status bits The source can be a constant or any integer element in files 0–7.
Chapter 14 Using High-Speed Counter Instructions Operation When the high-speed counter interrupt is enabled, user subroutine (file 4) is executed when: • A high or low preset is reached. • An overflow or underflow occurs. When in RSSN mode and in an idle condition, the high-speed counter interrupt is held off until the next scan trigger is received from the programming device. The high-speed counter accumulator counts while idle.
Chapter 14 Using High-Speed Counter Instructions Update High-Speed Counter Image Accumulator (OUT) Ladder representation: C5:0 ) UA When an OUT bit instruction is addressed for the high-speed counter (C0) UA bit, the value in the hardware accumulator is written to the value in the image accumulator (C0.ACC). This provides you with real-time access to the hardware accumulator value.
Chapter 14 Using High-Speed Counter Instructions Example 1 To enter the RRUN mode and have the HSC Outputs, ACC, and Interrupt Subroutine resume their previous state, apply the following: Ladder Rungs Rung 2:0 No action required. (Remember that all OUT instructions are zeroed when entering the RRUN mode. Use SET/RST instructions in place of OUT instructions in your conditional logic requiring retention.
Chapter 14 Using High-Speed Counter Instructions Example 2 To enter the RRUN mode and retain the HSC ACC value while having the HSC Outputs and Interrupt Subroutine reassert themselves, apply the following: Ladder Rungs Rung 2:0 Unlatch the C5:0/HP and C5:0/LP bits during the first scan BEFORE the HSC instruction is executed for the first time.
Chapter 14 Using High-Speed Counter Instructions Example 3 To enter the RRUN mode and have the HSC ACC and Interrupt Subroutine resume their previous state, while externally initializing the HSC outputs, apply the following: Ladder Rungs Rung 2:0 Unlatch or latch the output bits under HSC control during the first scan after the HSC instruction is executed for the first time. (Note, you could place this rung before the HSC instruction; however, this is not recommended.
Chapter 14 Using High-Speed Counter Instructions Instruction List File 2, Rung 0 Unlatch or latch the output bits under HSC control during the first scan after the HSC instruction is executed for the first time. (Note, you could place this rung before the HSC instruction; however, this is not recommended.
Chapter 14 Using High-Speed Counter Instructions High-Speed Counter Instructions in the Paper Drilling Machine Application Example To demonstrate the use of the HSC instruction, this section provides ladder rungs followed by the optimized instruction list for these rungs. The rungs are part of the paper drilling machine application example started in chapter 5. Refer to appendix E for the complete paper drilling machine application example.
Chapter 14 Using High-Speed Counter Instructions Adding to File 2 Ladder Rungs Rung 2:0 Initializes the high–speed counter each time that the RRUN mode is entered. The high–speed counter data area (N7:5 – N7:9) was chosen to correspond with the starting address (source address) of our HSL instruction. Note that the HSC instruction is disabled each entry into the RRUN mode until the first time that it is executed as true.
Chapter 14 Using High-Speed Counter Instructions Rung 2:1 This HSC instruction is not placed in the high–speed counter interrupt subroutine. If this instruction were placed in the interrupt subroutine, the high–speed counter could never be started or initialized (because an interrupt must first occur in order to scan the high–speed counter interrupt subroutine).
Chapter 14 Using High-Speed Counter Instructions Instruction List File 2, Rung 0 Initializes the high–speed counter each time the RRUN mode is entered. The high–speed counter data area (N7:5 – N7:9) corresponds with the starting address (source address) of the HSL instruction. The HSC instruction is disabled each entry into the RRUN mode until the first time that it is executed as true.
Chapter 14 Using High-Speed Counter Instructions File 2, Rung 2 Forces a high–speed counter low preset interrupt to occur each RRUN mode entry. An interrupt can only occur on the transition of the high–speed counter accum to a preset value (accum reset to 1, then 0). This is done to allow the high–speed counter interrupt subroutine sequencers to initialize.
Chapter 14 Using High-Speed Counter Instructions All presets are entered as a relative offset to the leading edge of a manual. The presets for the hole patterns are stored in the SQO instructions. (Refer to chapter 13 for the SQO instruction.) The high-speed counter external reset input (I/2) and the external hold input (I/3) are wired in parallel to prevent the high-speed counter from counting while the reset is active.

Chapter 15 Using Communication Protocols This chapter contains information about communication and the message (MSG) instruction.
Chapter 15 Using Communication Protocols Responder (Slave) Communication Responder products can only reply to other products. These devices are not capable of initiating an exchange of data; they only reply to requests made from initiator products. The Series A and B MicroLogix 1000 controllers are in this class.
Chapter 15 Using Communication Protocols The following table illustrates combinations of message types and target devices and their valid file types.

Chapter 15 Using Communication Protocols • Done Bit DN (bit 13) is set when the message is transmitted successfully. The DN bit is reset (cleared) the next time the rung goes from false to true. • Start Bit ST (bit 14) is set when the processor receives acknowledgement from the target device. This identifies that the target device has started to process the MSG request. The ST bit is reset when the DN, ER, or TO bit is set or on a false-to-true rung transition.
Chapter 15 Using Communication Protocols Controller Communication Status Bit When using the MSG instruction, you should also use the following controller communication status bit: Active Protocol Bit (S:0/11) – This is a read-only bit that indicates which communication protocol is currently enabled or functioning: where 0 = DF1 (default) and 1 = DH-485. Use this bit in your program to restrict message operation to a specific protocol.
Chapter 15 Using Communication Protocols To enter the function code, press: FUN L ANB 2 0 ANB 0 Note: When entering the target file type, the MicroLogix default file number is automatically inserted. If you want to change the file number, simply press the desired number.
Chapter 15 Using Communication Protocols Once the instruction is entered, the parameters are displayed as six screens, as shown here: P 0 0 8 M S G S L C 5 0 0 / M L T Y P E W R I T E P 0 0 8 N 0 M S G C B L K 0 0 0 0 H P 0 0 8 M S G N OD E 5 P 0 0 8 B 7 M S G L O C A L 0 0 0 0 H P 0 0 8 M S G T A R G R 9 1 : 8 2 P 0 0 8 M S G L E N 2 15–8
Chapter 15 Using Communication Protocols Timing Diagram for a Successful MSG Instruction The following section illustrates a successful timing diagram for a MSG instruction in a Series D or later MicroLogix 1000 discrete controller or a MicroLogix 1000 analog controller. Target node Rung goes True. receives packet. Control Block Status Bits Target node processes packet Target node successfully and returns data (read) or writes data (success). sent reply.
Chapter 15 Using Communication Protocols Step 4 is not shown in the timing diagram. If you do not receive an ACK, step 3 does not occur. Instead a NAK (no acknowledge) is received. When this happens, the ST bit remains clear. A NAK indicates: • • the Target Node is too busy, or it received a MSG packet with a bad checksum. No response indicates: • either the Target Node is not there, or • it does not respond because the MSG packet was corrupted in transmission.
Chapter 15 Using Communication Protocols Any MSG instruction that is in progress during a network protocol switch is not processed and is discarded. For more information on network protocol switching, see page 3–12. When an error condition occurs, the error code is stored in the lower byte of the first control word assigned to the MSG instruction. Error Code 02H Target node is busy. 03H Target node cannot respond because message is too large.
Chapter 15 Using Communication Protocols Application Examples that Use the MSG Instruction Example 1 – Continuously Writing Data from a MicroLogix Controller In this example, a communication link is created between two Series C or higher MicroLogix 1000 discrete controllers, where one controller is writing data to another. The communication link is set up for continuous operation with automatic recovery.
Chapter 15 Using Communication Protocols Rung 2:2 Write message with preceding logic. It is STRONGLY recommended that bit S2:0/11 (active protocol bit) be used to condition all message instructions. This bit only allows the message instruction to operate when the correct protocol is active.

The communication link is set-up for continuous operation with automatic recovery.
Chapter 15 Using Communication Protocols Rung 2:2 Write message with report by exception (RE) or change of state (COS) logic. COS is used to only transmit data/information when some type of change has occurred (time, data, etc.). This type of communications is extremely beneficial on networks because any time you can limit unnecessary traffic on a network, your ability to send information without delays is improved.
Chapter 15 Using Communication Protocols Example 4 – Continuously Reading and Writing Data with a MicroLogix Controller In this example, a communication link is created between two Series C or higher MicroLogix 1000 discrete controllers. This example creates a master/slave communication link between two controllers (one controller reading and writing data to another controller) with a MicroLogix 1000 as the master. The communication link is set-up for continuous operation with automatic recovery.
Chapter 15 Using Communication Protocols Rung 2:1 The Time Out bit (TO) associated with each message instruction is used to clear the controllers communication buffer and message instruction. Setting these bits, basically places the controllers communication section in the same condition as when the controller power up. These bits allow control program to reset or recover from unexpected events (e.g., errors, power problems, media problems).
Chapter 15 Using Communication Protocols Rung 2:3 This rung monitors the message instruction for “Done” conditions. When both messages are done, both messages are reset, allowing the sequence to be restarted in the next scan. The error retry bit is also used to reset both messages if an error or lockup condition is encountered.
Chapter 16 Instruction List Programming This chapter uses programming examples to teach you instruction list programming. The chapter also lists programming considerations. Programming Examples In the section Applying Logic to Your Schematics, page 6–11, you learned the concepts behind ladder logic. You were also shown the instruction list (Boolean) equivalent of a simple rung of logic. This section builds on that by showing you some more rung examples and their equivalent instruction list(s).
Chapter 16 Instruction List Programming Parallel Inputs When the inputs are in parallel, the instruction list representation is as follows: c a b Optimized NEW RUNG LD a OR b OUT c Option 1 NEW RUNG LD a LD b ORB OUT c Parallel Input Branching An input branch can be used to allow more than one combination of input conditions on parallel branches. An example of this type of rung is shown below.
Chapter 16 Instruction List Programming Parallel Block Connection If two blocks of instructions are connected in parallel, an ORB instruction is used. An example of this type of block connection is provided below. a b c d e Optimized NEW RUNG LD a AND b LD c AND d ORB OUT e Option 1 NEW RUNG LD a LD b ANB LD c AND d ORB OUT e Option 2 NEW RUNG LD a LD b ANB LD c LD d ANB ORB OUT e (See page 8–12 for more information regarding the use of the ORB instruction.
Chapter 16 Instruction List Programming Output Rung Examples This section shows you examples of output rungs and their optimized instruction list representation. Like the input rungs, many output rungs have more than one possible instruction list representation. Therefore, where applicable an optional representation is shown to the right of the optimized list. Single Output It is possible to have a rung made up of just an output. An example of such a rung is shown below.
Chapter 16 Instruction List Programming Example 1 – Multiple output circuit that does not require connecting instructions. b a c d Optimized Option 1 NEW RUNG LD a OUT b AND c OUT d NEW RUNG LD a OUT b LD c ANB OUT d Example 2 – This example requires MPS and MPP connecting instructions.

Chapter 16 Instruction List Programming Putting it All Together The example that follows combines all of the input and output concepts that have been presented to you. The optimized instruction list is shown beneath the rung.
Chapter 16 Instruction List Programming Programming Considerations 16–8 Since more than one instruction list representation may be possible for a single rung, you should be aware of the following programming issues if you are using programming software with your MicroLogix 1000 HHP: • Any rung created in the HHP and saved to the controller, uploaded to programming software and edited, downloaded to the controller, and then monitored by the HHP will have the optimized instruction list representation.
Chapter 17 Entering and Editing Your Program Read this chapter to enter and edit program files using your MicroLogix 1000 HHP. This chapter describes: • entering the program monitor • editing considerations • editing in append and overwrite modes • deleting instructions and rungs • searching for specific addresses Entering the Program Monitor Once you understand the structure of instruction lists, you can begin entering the instructions into the program files.
Chapter 17 Entering and Editing Your Program File names appear in the lower left-hand corner of only two of the Start of File screens. Program file 2 has the default name MAIN_PROG since it is the main program file, and file 3 has the default name USER_FAULT since this program file is only executed when a fault occurs. (The program file names can be changed using the programming software.) End of File Screen P 0 0 0 E N D F I L E : 0 2 As the name implies, this screen signifies the end of a program file.
Chapter 17 Entering and Editing Your Program Editing Considerations Before you begin to edit an existing program, you should store the program on a memory module (or save it on a personal computer with programming software). That way, if you edit a program and then decide that you don’t want to accept the edits you have made (i.e., you want the original program back), you can reload the original unedited program to the controller.
Chapter 17 Entering and Editing Your Program Important: You cannot add an instruction when the current display is the End of File screen. To add an instruction to the end of a rung, you must be on the rung’s last instruction. 3. Press the instruction key or enter the function code corresponding to the instruction you want to enter.

Chapter 18 After You’ve Entered Your Program Only User Password Designated Only Master Password Designated User Password and Master Password Designated You must enter the user password to gain access to the program. You do not have to enter the master password to gain access to the program. A master password is used by itself to allow access if a user password has been entered. You must enter either the user password or the master password to gain access to the program.
Chapter 18 After You’ve Entered Your Program 3. Type in a new password using any combination of the numbers available on the MicroLogix 1000 HHP keypad (i.e., 0–9). You can only use numeric-based passwords. The maximum length for a password is ten characters. 4. Enter the new password. E NT R E E N T E R P A S S W R D: Another screen appears so you can verify the new password. 5. Retype the new password, enter it, and return to the home screen.
Chapter 18 After You’ve Entered Your Program Setting the Run Always Bit This selection determines what mode the controller will enter at power up following a power down or an unexpected reset. When this bit is set to NO, the controller powers up in the mode it was in prior to losing power, with one exception: If the controller was in one of the test modes (RCSN or RSSN) when power was removed, the controller enters RPRG when power is applied.
Chapter 18 After You’ve Entered Your Program Setting the Start-Up Protection Bit This selection allows you to check for, and attempt to recover from, major errors before starting the first scan of your program. When this bit is set to NO, the controller will fault if a major error occurs while in RRUN, RCSN, or RSSN mode. When this bit is set to YES and power is cycled when the controller starts in RRUN mode, the controller executes the user-fault routine prior to the execution of the first program scan.
Chapter 18 After You’ve Entered Your Program Setting the Fault Override Bit If the controller is faulted while in RRUN mode, this selection determines whether or not the controller attempts to clear the errors at power up. When this bit is set to NO, after power is cycled in the controller, you must manually clear the faults that occurred while in RRUN mode.
Chapter 18 After You’ve Entered Your Program Setting the Extended I/O Configuration Bit When this bit is set to NO and unused outputs are written to, the controller will fault. Therefore, this bit must be set to YES if writing to unused outputs. (For a 16 I/O controller, O/6–O/15 are unused outputs. For a 32 I/O controller, O/12–O/15 are unused outputs.) Note: This selection is valid for Series A–C discrete only. To change the bit setting: 1.
Chapter 18 After You’ve Entered Your Program Setting the STI Setpoint The STI setpoint is the time between successive executions of the STI subroutine. The allowable range is from 10 ms to 2550 ms (entered in 10 ms increments). A setpoint of zero disables the setpoint function. Important: The setpoint value must be a longer time than the execution time of the STI subroutine file, or a minor error bit is set. To change the setting: 1. Access the program configuration menu. 2.
Chapter 18 After You’ve Entered Your Program Setting the STI Enabled Bit This selection determines if execution of the STI is allowed. When this bit is set to NO, execution of the STI is not allowed. When this bit is set to YES, execution of the STI is allowed (provided the STI setpoint is non-zero). If reset when an interrupt occurs, the STI subroutine does not execute and the STI Pending bit is set. The STI Timer continues to run when this bit is disabled. The STE instruction sets this bit.
Chapter 18 After You’ve Entered Your Program Selecting the Watchdog Scan This byte value contains the number of 10 ms ticks allowed during a program cycle. The default value is 10 (100 ms), but you can increase this to 255 (2.55 seconds) or decrease it to 1, as your application requires. Important: If the watchdog value equals the current scan time value, a watchdog major error will be declared (code 0022). To change the setting: 1. Access the program configuration menu. 2.
Chapter 18 After You’ve Entered Your Program Setting the Input Filters This option allows you to select input filter response times for the 1761-L16BWA and 1761-L32BWA micro controllers.

The higher you set the response time, the longer it takes for the input state change to reach the micro controller. However, setting higher response times also provides better filtering of high frequency noise.

Appendix B Programming Reference This appendix lists the: • controller status file • function codes • instruction execution times and instruction memory usage Controller Status File The status file lets you monitor how your operating system works and lets you direct how you want it to work. This is done by using the status file to set up control bits and monitor both hardware and software faults and other status information. Important: Do not write to reserved words in the status file.
Appendix B Programming Reference Word Function Page S:23 Reserved B–12 S:24 Index Register B–12 S:25 to S:29 Reserved S:30 STI Setpoint B–12 S:31 and S:32 Reserved B–12 B–12 Status File Descriptions The following tables describe the status file functions, beginning at address S0 and ending at address S32. Each status bit is classified as one of the following: • Status — Use these words, bytes, or bits to monitor controller operation or controller status information.
Address Classification Description S0/8➀ Extend I/O Configuration Bit Static Configuration This bit must be set by the user when unused outputs are written to. If reset and unused outputs are turned on the controller will fault (41H).
Appendix B Programming Reference Address S1/9➀ Bit Startup Protection Fault Classification Static Configuration Description When this bit is set and power is cycled when the controller powers up in Run mode, the controller executes the user-fault routine prior to the execution of the first scan of your program. You have the option of clearing the Major Error Halted bit S:1/13 to resume operation in the REM Run mode. If the user-fault routine does not reset bit S:1/13, the fault mode results.

Appendix B Programming Reference S2/6➀ Message Reply Pending Bit Status S2/7➀ Outgoing Message Command Pending Bit Status S2/8 to S2/13 S2/14 Reserved Math Overflow Selection NA Dynamic Configuration This bit is set when another node on the network has supplied the information you requested in the MSG instruction of your processor. This bit is cleared when the processor stores the information and updates your MSG instruction.
Appendix B Programming Reference Bit Classification Description Watchdog Scan Time Dynamic Configuration This byte value contains the number of 10 ms ticks allowed to occur during a program cycle. The default value is 10 (100 ms), but you can increase this to 255 (2.55 seconds) or decrease it to 1, as your application requires. If the program scan S:3L value equals the watchdog value, a watchdog major error is declared (code 0022).
Appendix B Programming Reference Address Bit Classification Description S5/2 Control Register Error Dynamic Configuration If this bit is ever set upon execution of the END or TND instruction, major error (0020) is declared. To avoid this type of major error from occurring, examine the state of this bit following a control register instruction, take appropriate action, and then clear bit S:5/2 using an OTU instruction with S:5/2.
Appendix B Programming Reference Each fault is classified as one of the following: • Non-User — A fault caused by various conditions that cease logic program execution. The user-fault routine is not run when this fault occurs. • Non-Recoverable — A fault caused by the user that cannot be recovered from. The user-fault routine is run when this fault occurs. However, the fault cannot be cleared.
Appendix B Programming Reference Fault Classification User Address Error Code (Hex) Run Errors Non-User S6 0004 A runtime memory integrity error occurred. X 0020 A minor error at the end of the scan. Refer to S:5. 0022 The watchdog timer expired. Refer to S:3H. X 0024 Invalid STI interrupt setpoint. Refer to S:30. X 0025 There are excessive JSRs in the STI subroutine (file 5). X 0027 There are excessive JSRs in the fault subroutine (file 3).
Appendix B Programming Reference Address S7 Bit Suspend Code Classification Status S8 to S12 S13 and S14 Reserved Math Register NA Status Description When a non-zero value appears in S:7, it indicates that the SUS instruction identified by this value has been evaluated as true and the Suspend Idle mode is in effect. This pinpoints the conditions in the application that caused the Suspend Idle mode. This value is not cleared by the controller.
Appendix B Programming Reference Classification Status S17 to S21 S22 Reserved Maximum Observed bser e Scan ca Time i e NA Dynamic Configuration fi ra i Description This byte value contains the baud rate of the processor on the DH-485 link. The controller baud rate options are: • 9600 • 19200 (default) To change the baud rate from the default value, you must use a programming device. NA This word indicates the maximum observed interval between consecutive program cycles.

Appendix D Understanding the Communication Protocols Use the information in this appendix to understand the differences in communication protocols. The following protocols are supported from the RS-232 communication channel: • DF1 Full-Duplex and DF1 Half-Duplex Slave All MicroLogix 1000 controllers support the DF1 full-duplex protocol. Series D or later discrete and all MicroLogix 1000 analog controllers also support DF1 half-duplex slave protocol.
Appendix D Understanding the Communication Protocols DF1 Full-Duplex Protocol DF1 Full-Duplex communication protocol combines data transparency (ANSI — American National Standards Institute — specification subcategory D1) and two-way simultaneous transmission with embedded responses (subcategory F1).
Appendix D Understanding the Communication Protocols Example: DF1 Full-Duplex Connections For information about required network connecting equipment, see chapter 3, Connecting the System. Micro Controller Optical Isolator➀ (recommended) 1761-CBL-PM02 Personal Computer Modem Cable Personal Computer Modem Optical Isolator➀ (recommended) Modem Micro Controller 1761-CBL-PM02 ➀ We recommend using an AIC+, catalog number 1761-NET-AIC, as your optical isolator.
Appendix D Understanding the Communication Protocols DF1 Half-Duplex Slave Protocol DF1 half-duplex slave protocol provides a multi-drop single master/multiple slave network. In contrast to DF1 full-duplex, communication takes place in one direction at a time. You can use the RS-232 port on the MicroLogix as both a half-duplex programming port, as well as a half-duplex peer-to-peer messaging port. The master device initiates all communication by “polling” each slave device.
Appendix D Understanding the Communication Protocols DF1 Half-Duplex Slave Configuration Parameters When the system mode driver is DF1 half-duplex slave the following parameters can be viewed and changed only when the programming software is online with the processor. The DF1 half-duplex slave parameters are not stored as part of the controller downloadable image (with the exception of the baud rate and node address).
Appendix D Understanding the Communication Protocols RS-232 (DF1 Protocol) Modem Modem MicroLogix 1000 Programmable Controller (Series D) SLC 5/03 Processor Modular Controller Rockwell Software WINtelligent LINX, RSLinx 2.
Appendix D Understanding the Communication Protocols With the addition of DF1 half-duplex slave protocol, the controller clears the file ownership if no supported commands are received from the owner within the timeout period. If the file ownership were not cleared after a download sequence interruption, the processor would not accept commands from any other devices because it would assume another device still had file ownership.
Appendix D Understanding the Communication Protocols Leased-Line Modems Leased-line modems are used with dedicated phone lines that are typically leased from the local phone company. The dedicated lines may be in a point-to-point topology supporting full-duplex communications between two modems or in a point-to-multipoint topology supporting half-duplex communications between three or more modems.
Appendix D Understanding the Communication Protocols DH-485 Communication Protocol The information in this section describes the DH-485 network functions, network architecture, and performance characteristics. It also helps you plan and operate the MicroLogix 1000 on a DH-485 network. Important: Only Series C or later MicroLogix 1000 discrete controllers and all MicroLogix 1000 analog controllers support the DH-485 network.
Appendix D Understanding the Communication Protocols DH-485 Configuration Parameters When the system mode driver is DH-485 Master, the following parameters can be changed: Parameter Baud Rate Node Address Max Node Address Token Hold Factor Description Toggles between the communication rate of 9600 and 19200. This is the node address of the processor on the DH-485 network. The valid range is 1–31. This is the maximum node address of an active processor.

Appendix D Understanding the Communication Protocols Important DH-485 Network Planning Considerations Carefully plan your network configuration before installing any hardware.
Appendix D Understanding the Communication Protocols Planning Cable Routes Follow these guidelines to help protect the communication cable from electrical interference: • Keep the communication cable at least 1.52 m (5 ft) from any electric motors, transformers, rectifiers, generators, arc welders, induction furnaces, or sources of microwave radiation. • If you must run the cable across power feed lines, run the cable at right angles to the lines.
Appendix D Understanding the Communication Protocols Number of Nodes The number of nodes on the network directly affects the data transfer time between nodes. Unnecessary nodes (such as a second programming terminal that is not being used) slow the data transfer rate. The maximum number of nodes on the network is 32. Setting Node Addresses The best network performance occurs when node addresses are assigned in sequential order.

Appendix D Understanding the Communication Protocols MicroLogix Remote Packet Support Series D MicroLogix discrete controllers and all MicroLogix analog controllers can respond to communication packets (or commands) that do not originate on the local DH-485 network. This is useful in installations where communication is needed between the DH-485 and DH+ networks. The example below shows how to send messages from a PLC device or a PC on the DH+ network to a MicroLogix 1000 controller on the DH-485 network.
Appendix E Application Example Programs This appendix is designed to illustrate various instructions described previously in this manual.
Appendix E Application Example Programs Paper Drilling Machine Application Example For a detailed explanation of: • LD, LDI, OUT, RES, SET, RST, and OSR instructions, see chapter 8. • EQU and GEQ instructions, see chapter 9. • CLR, ADD, and SUB instructions, see chapter 10. • MOV and FRD instructions, see chapter 11. • JSR and RET instructions, see chapter 12. • INT and SQO instructions, see chapter 13. • HSC, HSL, and RAC instructions, see chapter 14.
Appendix E Application Example Programs Drill Mechanism Operation When the operator presses the start button, the drill motor turns on. After the book is in the first drilling position, the conveyor subroutine sets a drill sequence start bit and the drill moves toward the book. When the drill has drilled through the book, the drill body hits a limit switch and causes the drill to retract up out of the book.
Appendix E Application Example Programs Paper Drilling Machine Ladder Program Rung 2:0 Initializes the high-speed counter each time the RRUN mode is entered. The high-speed counter data area (N7:5 – N7:9) corresponds with the starting address (source address) of the HSL instruction. The HSC instruction is disabled each entry into the RRUN mode until the first time that it is executed as true.
Appendix E Application Example Programs Rung 2:1 This HSC instruction is not placed in the high-speed counter interrupt subroutine. If this instruction were placed in the interrupt subroutine, the high-speed counter could never be started or initialized (because an interrupt must first occur in order to scan the high-speed counter interrupt subroutine).
Appendix E Application Example Programs Rung 2:5 Calls the drill sequence subroutine. This subroutine manages the operation of a drilling sequence and restarts the conveyor upon completion of the drilling sequence. | +JSR–––––––––––––––+ | |––––––––––––––––––––––––––––––––––––––––––––––––+JUMP TO SUBROUTINE+–| | |SBR file number 6| | | +––––––––––––––––––+ | Rung 2:6 Calls the subroutine that tracks the amount of wear on the current drill bit.
Appendix E Application Example Programs Rung 4:1➀ Keeps track of the hole number that is being drilled and loads the correct high-speed counter preset based on the hole count. This rung is only active when the ”hole selector switch” is in the ”3-hole” position. The sequencer uses step 0 as a null step upon reset. It uses the last step as a ”go forever” in anticipation of the ”end-of-manual” hard-wired external reset.
Appendix E Application Example Programs Rung 4:3➀ Is identical to the two previous rungs except that it is only active when the ”hole selector switch” is in the ”7-hole” position.
Appendix E Application Example Programs Rung 6:0 This section of ladder logic controls the up/down motion of the drill for the book drilling machine. When the conveyor positions the book under the drill, the DRILL SEQUENCE START bit is set. This rung uses that bit to begin the drilling operation. Because the bit is set for the entire drilling operation, the OSR is required to be able to turn off the forward signal so the drill can retract.
Appendix E Application Example Programs Rung 7:0 Examines the number of 1/4 in. thousands that have accumulated over the life of the current drill bit. If the bit has drilled between 100,000–101,999 1/4 in. increments of paper, the ”change drill” light illuminates steadily. When the value is between 102,000–103,999, the ”change drill” light flashes at a 1.28 second rate. When the value reaches 105,000, the ”change drill” light flashes and the ”change drill now” light illuminates. | 1/4 in.
Appendix E Application Example Programs Rung 7:1 Resets the number of 1/4 in. increments and the 1/4 in. thousands when the ”drill change reset” keyswitch is energized. This should occur following each drill bit change. | drill change 1/4 in. | | reset keyswitch Thousands | | I:0 +CLR–––––––––––––––+ | |––––] [–––––––––––––––––––––––––––––––––––––+–+CLEAR +–+–| | 8 | |Dest N7:11| | | | | | 0| | | | | +––––––––––––––––––+ | | | | 1/4 in.
Appendix E Application Example Programs Rung 7:3 Converts the BCD thumbwheel value from BCD to integer. This is done because the controller operates upon integer values. This rung also ”debounces” the thumbwheel to ensure that the conversion only occurs on valid BCD values. Note that invalid BCD values can occur while the operator is changing the BCD thumbwheel. This is due to input filter propagation delay differences between the 4 input circuits that provide the BCD input value.
Appendix E Application Example Programs Rung 7:6 When the number of 1/4 in. increments surpasses 1000, finds out now many increments are past 1000 and stores in N7:20. Adds 1 to the total of ’1000 1/4 in.’ increments and re-initializes the 1/4 in. increments accumulator to how many increments were beyond 1000. | 1/4 in.
Appendix E Application Example Programs Paper Drilling Machine Instruction List Program File 2, Rung 0 Initializes the high-speed counter each time the RRUN mode is entered. The high-speed counter data area (N7:5 – N7:9) corresponds with the starting address (source address) of the HSL instruction. The HSC instruction is disabled each entry into the RRUN mode until the first time that it is executed as true.
Appendix E Application Example Programs File 2, Rung 2 Forces a high-speed counter low preset interrupt to occur each RRUN mode entry. An interrupt can only occur on the transition of the high-speed counter accum to a preset value (accum reset to 1, then 0). This is done to allow the high-speed counter interrupt subroutine sequencers to initialize.

Appendix E Application Example Programs File 4, Rung 0 Resets the hole count sequencers each time that the low preset is reached. The low preset has been set to zero to cause an interrupt to occur each time that a reset occurs. The low preset is reached anytime that a reset C5:0 or hardware reset occurs. This ensures that the first preset value is loaded into the high-speed counter at each entry into the RRUN mode and each time that the external reset signal is activated.
Appendix E Application Example Programs File 4, Rung 2 Is identical to the previous rung except that it is only active when the ”hole selector switch” is in the ”5-hole” position.

Appendix E Application Example Programs File 6, Rung 1 When the drill has drilled through the book, the body of the drill actuates the DRILL DEPTH limit switch. When this happens, the DRILL FORWARD signal is turned off and the DRILL RETRACT signal is turned on. The drill is also retracted automatically on power up if it is not actuating the DRILL HOME limit switch.
Appendix E Application Example Programs File 7, Rung 0 Examines the number of 1/4 in. thousands that have accumulated over the life of the current drill bit. If the bit has drilled between 100,000–101,999 1/4 in. increments of paper, the ”change drill” light illuminates steadily. When the value is between 102,000–103,999, the ”change drill” light flashes at a 1.28 second rate. When the value reaches 105,000, the ”change drill” light flashes and the ”change drill now” light illuminates.

Appendix E Application Example Programs File 7, Rung 3 Converts the BCD thumbwheel value from BCD to integer. This is done because the controller operates upon integer values. This rung also ”debounces” the thumbwheel to ensure that the conversion only occurs on valid BCD values. Note that invalid BCD values can occur while the operator is changing the BCD thumbwheel. This is due to input filter propagation delay differences between the 4 input circuits that provide the BCD input value.
Appendix E Application Example Programs File 7, Rung 5 Keeps a running total of how many inches of paper have been drilled with the current drill bit. Every time a hole is drilled, adds the thickness (in 1/4 ins) to the running total (kept in 1/4 ins). The OSR is necessary because the ADD executes every time the rung is true, and the drill body would actuate the DRILL DEPTH limit switch for more than 1 program scan.
Appendix E Application Example Programs Time-Driven Sequencer Application Example The following application example illustrates the use of the TON and SQO instructions in a traffic signal at an intersection. The timing requirements are: • Red light – 30 seconds • Yellow light – 15 seconds • Green light – 60 seconds The timer, when it reaches its preset, steps the sequencer that in turn controls which traffic signal is illuminated.

Appendix E Application Example Programs Event-Driven Sequencer Application Example The following application example illustrates how the FD (found) bit on an SQC instruction can be used to advance an SQO to the next step (position). This application program is used when a specific order of events is required to occur repeatedly. By using this combination, you can eliminate using the XIO, XIC, and other instructions. For a detailed explanation of: • LD, LDI, and RES instructions, see chapter 8.
Appendix E Application Example Programs Event Driven Sequencer Instruction List Program File 2, Rung 0 Ensures that the SQO always resets to step (position) 1 each RRUN mode entry. (This rung actually resets the control register’s position and EN enable bit to 0. Due to this the following rung sees a false to true transition and asserts step (position) 1 on the first scan.) Eliminate this rung for retentive operation.

At the same time, the high-speed counter tells the gripper to release the part and start the dwell timer. After the dwell time has expired, start up the reverse motor to send the head back to its home position to pick up another part.
Appendix E Application Example Programs RPM Calculation Application Example The following application example illustrates how to calculate the frequency and RPM of a device (such as an encoder) connected to a high-speed counter. The calculated values are only valid when counting up. For a detailed explanation of: • LD, LDI, CTU and TON instructions, see chapter 8. • LES instruction, see chapter 9. • CLR, MUL, DIV, DDV, ADD, and SUB instructions, see chapter 10. • MOV instruction, see chapter 11.
Appendix E Application Example Programs To maintain validity, you must ensure that you cannot accumulate more pulses per rate period than counts per revolution. For example, if you have selected a 1000 pulse encoder, you cannot have more than 999 counts occur in any 1 rate measurement period. If you determine that you exceed this rule, simply lower your Rate Measurement Period T0.PRE. RPM Calculation Ladder Program Rung 2:0 Ensures that the measurement value is initialized each RRUN mode entry.
Appendix E Application Example Programs Rung 2:2 Calculates and stores the number of counts that have occurred since the last time that it was executed as true in N7:1 (last time=last rate measurement timer (T4:0) expiration). The LES instruction allows for 10 counts of backlash to occur (you can adjust as needed). The add instruction is configured for a 1000 count encoder using N7:2.

Appendix E Application Example Programs Spray Booth Operation Overview An overhead conveyor with part carriers (hooks) carries parts from a previous operation to the spray booth. Before the part enters the spray booth, two items are checked on the conveyor. The first check is for part presence and the second check is for the needed color. This information is stored and accessed later when the part carrier is in the paint spraying area.

Appendix F Optional Analog Input Software Calibration This appendix helps you calibrate an analog input channel using software offsets to increase the expected accuracy of an analog input circuit. Examples of equations and a ladder diagram are provided for your reference. Software calibration reduces the error at a given temperature by scaling the values read at calibration time. Calibrating an Analog Input Channel The following procedure can be adapted to all analog inputs; current or voltage.
Appendix F Optional Analog Input Software Calibration Calculating the Software Calibration Use the following equation to perform the software calibration: Scaled Value = (input value x slope) + offset Slope = (scaled max. – scaled min.) / (input max. – input min.) Offset = Scaled min. – (input min. x slope) Calibration Procedure 1. Heat up / cool down your MicroLogix 1000 system to the temperature in which it will normally be operating. 2.
Appendix F Optional Analog Input Software Calibration Once the calibration procedure is complete, set the CONVERSION ENABLE bit to 1. The calibration numbers are then used to scale the raw analog data. The corrected analog input data is placed in memory location ANALOG_SCALED. The following symbols are used in this example: CAL_LO_ENABLE = B3/500 CAL_HI_ENABLE = B3/501 CALIBRATE = B3/502 CONVERSION ENABLE = B3/503 ANALOG_IN = I:0.

Glossary Glossary The following terms are used throughout this manual. Refer to the Allen–Bradley Industrial Automation Glossary, Publication Number AG–7.1, for a complete guide to Allen–Bradley technical terms. address: A character string that uniquely identifies a memory location. For example, I1/0 is the memory address for the data located in the Input file location word1, bit 0. application: 1) A machine or process monitored and controlled by a controller.
Glossary counter: 1) An electro–mechanical relay–type device that counts the occurrence of some event. May be pulses developed from operations such as switch closures, interruptions of light beams, or other discrete events. 2) In controllers a software counter eliminates the need for hardware counters. The software counter can be given a preset count value to count up or down whenever the counted event occurs.
Glossary inrush current: The temporary surge current produced when a device or circuit is initially energized. instruction: A mnemonic and data address defining an operation to be performed by the controller. A rung in a program consists of a set of input and output instructions. The input instructions are evaluated by the controller as being true or false. In turn, the controller sets the output instructions to true or false. Instruction List program: A program written in a list format using mnemonics.
Glossary negative logic: The use of binary logic in such a way that “0” represents the voltage level normally associated with logic 1 (for example, 0 = +5V, 1 = 0V). Positive is more conventional (for example, 1 = +5V, 0 = 0V). network: A series of stations (nodes) connected by some type of communication medium. A network may be made up of a single link or multiple links. nominal input current: The current at nominal input voltage.
Glossary protocol: The packaging of information that is transmitted across a network. read: To acquire data from a storage place. For example, the controller READs information from the input data file to solve the program. relay: An electrically operated device that mechanically switches electrical circuits. relay logic: A representation of the program or other logic in a form normally used for relays. restore: To download (transfer) a program from a personal computer to a controller.
Glossary terminal: A point on an I/O module that external I/O devices, such as a push button or pilot light, are wired to. throughput: The time between when an input turns on and the corresponding output turns on. true: The status of an instruction that provides a continuous logical path on a ladder rung. upload: Data is transferred to a programming or storage device from another device.
