5 - PLC Memory & I/O Configuration Overview This chapter shows you how to set up and configure your Siemens family PLC. You must configure your PLC before you can create a ladder logic program. Configuration is part of the program; it performs the important function of relating the hardware components to the logic components. The setup and configuration process is completed in three steps in recommended order: 1. 2. 3.
PLC Type Setup (Offline) The setup and configuration process begins with PLC Type Setup. You must tell 505 SoftShop what processor you are using before you can configure the processor. Valid PLC types are: • Simatic 520 revision 1101. • Simatic 520c revision 1101 and 1102. • Simatic 525 revision 1102 and 1104. • Simatic 530 revision 1102, 1104, and 1108. • Simatic 530c revision 1104, 1108, and 1112. • Simatic 535 revision 1104, 1108, and 1112. • Simatic 560 revision 2120.
PLC Setup Option Description PLC Type Specifies the type of processor. Selection of PLC type determines choices available for remaining setup options in the PLC Type Setup dialog box. PLC Memory Size Specifies the PLC's memory size. Only the valid memory sizes for the PLC selected in PLC Type are displayed. Table 5.1 4. Click OK or press Enter to save your settings and return to the active logic program. Changing PLC Types The PLC type can be changed even after programming has been initiated.
System Memory • RLL instruction tables: drum, timer/counter, shift register, etc. • Image registers and control and relays.* • Subroutine parameter area.* • SF program temporary memory.* • Status Word memory.* System Operation * Not Configurable Table 5.2 The configuration process begins with PLC Configuration.
Accessing PLC Configuration 1. Select PLC Configuration from the PLC Utilities menu. Result: The PLC Configuration dialog box appears (Figure 5.2). Figure 5.2 2. Enter the appropriate ranges for the selected PLC memory type. NOTE The processor type must be selected before configuration. The various memory types are described in the pages that follow. Memory types are classified for RLL programming purposes in the following ways: 3. • Writeable - This memory type is read/write.
RLL instruction used in the program requires one or more 16-bit words of L-Memory. Image Register Memory A block of memory within the controller is reserved for maintaining the status of discrete inputs/outputs. This memory type is called the discrete image register. A word image register holds the values of word inputs/outputs. Control Relay Memory A block of memory within the controller is reserved for control relays.
Timer/Counter Memory A block of memory within the controller is reserved for the operation of the timer/counter group of RLL instructions, including the following: Timer (TMR, TMRF) Counter (CTR) Discrete Control Alarm Timer(DCAT) Motor Control Alarm Timer(MCAT) Up/Down Counter (UDC) When you assign a number to a timer, counter, up/down counter, or discrete/motor control alarm timer, be sure that you do not use that number for any other timer, counter, up/down counter, or discrete/motor control alarm t
Table Move Memory A block of memory within the controller is reserved for the operation of the table move instructions, including the following: • Move Word To Table (MWTT). • Move Word From Table (MWFT). When you assign a number to a table move instruction, be sure that you do not use that number for any other table move instruction. For example, if you configure a Move Word To Table #1 (MWTT1), do not configure a Move Word From Table #1 (MWFT1).
Shift Register Memory A block of memory within the controller is reserved for the operation of the shift registers, which include the following: • Bit Shift Register (SHRB). • Word Shift Register (SHRW). When you assign a number to a shift register, be sure that you do not use that number for any other shift register type. For example, do not configure SHRB11 and SHRW11.
the counts-per-step values are stored as 16 consecutive 16-bit words in DCP-Memory (except for the DRUM). For the DRUM instruction, counts-per-step values are stored in L-Memory; DCP is not used. NOTE If you use an operator interface to change the drum preset values (DSP or DCP), the new values are not changed in the original RLL program. If the RLL presets are ever downloaded, e.g.

I/O Configuration Controller Functionality in Configuration Keep in mind that, while you can configure I/O either online (with the controller) or offline (programming device only), functional differences exist between the two modes. When online, you can perform those functions that require interfacing with the controller. For instance, you must be online to write your I/O configuration to the controller or to read the configuration of a base from the base itself.
Figure 5.6 NOTE If you need to select a different Base number, you can do so by clicking on the Next Base or Prev Base button on the Edit I/O Base dialog box. You can also click on the Search Base button on the Edit I/O Base dialog box and enter a different base number. 3. Use the mouse or arrow keys to highlight the desired slot number to be configured. 4. Click on the Edit Slot button on the dialog box or press Enter. Result: The Edit I/O Slot dialog box appears (Figure 5.6). Figure 5.6 5.
Clearing a Base I/O Configuration 1. Start from Edit I/O Base dialog box (Figure 5.6). 2. Click on the Clear Base button on the Edit I/O Base dialog box. You have finished setting up the software and the hardware. The next step is programming. The Programming chapter discusses 505 SoftShop’s many different features for developing ladder logic. You can program in online or offline mode.
Task Comment Open a file in COM PROFIBUS. You can modify an existing configuration file, if appropriate, or create a new file. Select a master. Required. Choose the 505-CP5434-DP. Select a host. Required. Choose the appropriate Series 505 CPU. Modify bus parameters. Optional. You can accept the default settings, unless you wish to modify one, such as baud rate. Assign slave(s). Required. Choose slave(s), such as the 505 PROFIBUS-DP RBC, up to 112. Parameterize slave(s). Optional.
To import and/or configure data from the COM PROFIBUS software, you must be running 505 SoftShop, and the binary file (with its .2BF extension) that you created with COM PROFIBUS must be in a known location. Follow the steps below to execute: 1. Select PLC Configuration from the PLC Utilities menu. Result: The PLC Configuration dialog box appears (Figure 5.2). 2. Select the Profibus I/O button under I/O configuration on the PLC Configuration dialog box. Result: The Profibus-DP I/O dialog box appears.
Merge COM PROFIBUS Follow the steps below to merge in the COM PROFIBUS: 1. Click on the Merge button to execute the merge function. You are prompted to supply the name of the binary file from which you wish to import configuration data. 2. At the prompt, either type in the name of the binary file, or click the browse button to search other drives or directories.
Figure 5.8 The Edit Slave dialog box allows you to perform the following tasks: • The Search Slave button allows you to go to and edit other slave addresses without going back to the Profibus-DP I/O dialog box. • The Next Slave button allows you to go to and edit the next slave address in numerical increasing order without going back to the Profibus-DP I/O dialog box.
• For bit or bit-and-word modules (but not for word-only modules), the number for the I/O address must begin on an 8point boundary. An 8-point boundary is (n*8) + 1, e.g., 1, 9, 17, etc. Addresses not starting on an 8-point boundary are changed to do so when you write the values. • SoftShop does not flag duplicate I/O points. However, the Find I/O functions under the PLC Configuration dialog box can be used to search for duplicate I/O points. To Edit the I/O Address: 1.
Profibus Operations Profibus Operations allows you to change the operations mode from Operate to Stop, or Stop to Operate. You can also select from Synchronous to Asynchronous, or Asynchronous to Synchronous. The Profibus Operations mode can be selected from the Profibus-DP I/O dialog box (Figure 5.7) by: 1. Clicking on the Profibus Ops. Button or selecting Profibus Operations from the PLC Utilities menu. Result: The Profibus Operations dialog box appears (Figure 5.9). Figure 5.
6 - Programming Overview In this chapter, you will discover how to enter and modify logic using 505 SoftShop's features. Remember, in the Windows environment there is usually more than one way to complete a task. 505 SoftShop provides keyboard support to access all commands. You may find that the most efficient method of programming will be through a combination of keyboard and mouse techniques. Refer to Appendix A for a concise list of keyboard supported commands.
Using the Logic Editor The Logic Editor is where to begin programming since it allows you to display, access, and/or modify logic in the active logic program. You can view existing programs, or you can create a new one. To view an existing program: 1. Open or Import a logic program (see open program). 2. If there is logic in the program but does not appear, click on the toolbar or select Logic Editor from the View menu. Programming Ladder Several logic program windows can be displayed simultaneously.
5. Repeat Step 3 to enter additional networks. Insert a New Row You can insert a new row to a network similar to inserting a new network. In the active logic program window, use the mouse or keyboard to place the cursor on an existing row in the network. To enter a new row using the mouse: 1. Click (new row) on the Toolbar. Notice that the new row attaches to the pointer. 2. Place the pointer in the position where you want the new row to appear. 3.
7. If the sticky cursor has not been turned on in the Program Setup then after the instruction has been dropped into place the pointer returns to an arrow. To Enter Mnemonic Instructions with the Keyboard: 1. In the active logic program, position the cursor (by using the arrow keys) where the instruction is to be located. 2. Type in the instruction mnemonic at the cursor location and press ENTER. If you forget an instruction mnemonic just enter a ? and press enter.

9 - PID Loops Overview Process and batch control capability is provided using the controller’s proportional-integral-derivative (PID) loop functions, illustrated in Figure 9.1. When you program a loop, you can set the same eight alarm types used by analog alarms and described in Chapter 8. • High-high alarm point on the process variable (PV). • High alarm point on the PV. • Low alarm point on the PV. • Low-low alarm point on the PV. • Yellow deviation alarm point referenced to the setpoint (SP).
A PV alarm deadband is provided to minimize cycles in and out of alarm (chattering) that generate large numbers of messages when the PV hovers near one of the alarm limits. An option is also available to call a Special Function Program to initiate a special function calculation. The SF program call can be scheduled on the PV, the SP, or the output. Programming PID Loop The PID Loop Editor gives you the ability to display, access, and/or modify PID Loops. To access the PID Loop Editor: 1.
Figure 9.2 PID Title An eight character title can be entered for each specific PID Loop number. The title is optional and can be left blank. PID Algorithm Select POS for the position algorithm or VEL for the velocity algorithm in the PID Algorithm field. For the position algorithm, the position of the device being controlled is computed based on the error. The velocity form of the PID algorithm computes the change in the device position based on the error.

You must specify the engineering values that correspond to the upper range of the input span. Process Variable Bipolar Select YES or NO to specify analog inputs as bipolar or not. Bipolar inputs span have spans of -5 to 5 volts, or -10 to 10 volts. 20% Offset of Process Variable Select No for no offset, and Yes for 20% offset. A span of 0 to 5.0 volts (0 to 20 milliamps ) is referred to as a span of 0 to 100%. A span of 1 to 5.
Monitor Low/High Select Yes to have the controller monitor the Low/High Alarm; otherwise, select No. The Low/High Loop can be entered as values requiring remedial action. Process Variable Alarm Low-Low Enter a real number in engineering units; must be less than or equal to low Alarm value, and greater than or equal to low range of Process Variable. Process Variable Alarm Low Enter a real number in engineering units; must be less than or equal to high Alarm value of Process Variable.
Freeze Bias Select YES or NO in the Freeze Bias field. Select No to have the bias adjusted when the output goes out of range. Select Yes to have the bias frozen when the output goes out of range. Derivative Gain Limiting Select Yes or No in the Derivative Gain Limiting field to have derivative gain limiting done. If you specify No, then derivative gain limiting is not done, even if a value is entered in the Limiting Coefficient field.
The control, equation with error squared is based on signed error squared, instead of the error alone. To implement a high gain for large errors, and no gain for small errors, incorporate an error deadband. When error deadband is selected, the controller does not take any action on the output if the process variable is within the yellow deviation limits.
Monitor Rate of Change To have the controller monitor the rate of change, select Yes in the Monitor Deviation field; otherwise, select No. Rate of Change Loop Enter a value in engineering units for the rate of change Alarm in the Rate of Change Alarm field. Monitor Broken Transmitter Alarm To have the controller monitor the Broken Transmitter Alarm, select Yes in the Monitor Broken Transmitter Alarm field; otherwise, select No.
Ramp/Soak Setpoint The ramp/soak feature allows you to define a variation for the process variable by specifying the time characteristics of the loop setpoint (Figure 9.4). The capability of varying the loop setpoint can be useful in a number of processes such as heat treating and batch cooking. Time Figure 9.4 Example Ramp/Soak Cycle You can use simple ramp operations to improve some process startup procedures. For example, the controllers do a bumpless transfer from manual to automatic mode.
currently contained in LRSN. Note that the step number is zero-based. LRSN contains 0 when the profile is on step #1, 1 when the profile is on step #2, etc. Using the Ramp/Soak Flags - Each loop ramp/soak profile has a corresponding 16-bit variable, LRSF, that contains operational and status information for the profile. When you program a ramp/soak profile, you may optionally specify a RAMP/SOAK FLAG ADDRESS.
Editor The Ramp/Soak Editor allows you to Edit or Delete an existing programmed step or Insert a new one. To access the Ramp/Soak Editor: 1. Click PID Loop from the View menu (Alt+V,P). The PID Loop Directory dialog box appears (Figure 9.1a). The dialog box shows the Loop Mode, Loop number (1-64), Loop Title, and Enable/Disable state. 2. Select the PID Loop number that you want to enter or edit Ramp/Soak by using the left mouse button or the Arrow keys on the keyboard. 3.
Table 9.2 BIT LOOP/FUNCTION 1 1= Restart at the first step. To restart, toggle bit off, on, then off again. The restart occurs on the trailing edge of a square wave. 2 1= Hold at current step. To hold, set bit on. 3 1= Jog to next step. To jog, set bit on. Jog occurs on the rising edge of a square wave. 4 1= Finish. Indicates ramp/soak is completed. 5 1= Wait. This bit is set during a soak period when the process variable is not within a specified deviation from the SP.
SmarTune temporarily puts a loop into manual mode. It makes a selectable change to a loop’s output (Mn) to cause a process variable (PV) movement toward the center of the PV span. Resultant PV changes are sampled. After sampling criteria is met, sampled values are used to calculate theoretical optimum gain (Kc), reset (Ti), and rate (Td). Theoretical optimums are converted to pragmatic optimums by a heuristic and assigned.
Figure 9.6 Now enter each appropriate variable for the autotune process. The following section describes, in general terms, each variable and the PID autotune process for a temperature control loop. Caution SmarTune should not be used if a process might experience harmful effects as a result of arbitrary Mn assignment. During a tuning session, Mn values are assigned in such a way as to determine the frequency response of a process.
The PID algorithm consists of three components: the Proportional, the Integral (Reset), and the Derivative (Rate). Each component impacts the output to address the varied characteristics of the process variable.
Figure 9-8 Steady State Error Thermal loading is induced by energy losses to the surroundings, conduction through the machine, as well as the process. A proportionalonly controller can resolve this error only to a limited degree. The Integral Component The integral term of the PID expression provides a means to eliminate the error in the proportional band. This term is defined as the Error integrated over time.
Essentially, the SmarTune utility creates a disturbance by initiating a step increase of the PID output. Process variable samples are collected as this increase in output precipitates a change in the process variable. When the sample period is complete, the data collection is analyzed for time lag, gradient, overshoot, steady state error, and oscillation. Using a frequency analysis method, the optimum PID gain values are determined.

Allowed discrete variables include bits in a V-memory word. • When Start Variable transitions from a false to a true, a SmarTune session is activated. • When Abort Variable is true, a SmarTune session is deactivated.
conceived for use when Automatic Download has been configured as false, but may be used for other purposes. If Automatic Download is false, a loop is left in manual mode with its output set to Safe Output when a tuning session has completed. When Automatic Download is true, a loop is switched back to its previous mode and is assigned its previous SP on completion.

Table 9-5 lists the value parameters used by SmarTune, with the default values and the ranges possible for each. Table 9-5 Name Default Value Range Max Time 30.
Max Time Max Time is a time in minutes. When a SmarTune session is started, a timer is set to this value. If that timer expires before the session has completed, the session is aborted with an error (see Table 9-4). Noise Band When electrical signals are converted to values, they vary randomly by insignificant amounts. An insignificant amount is application dependent. Noise Band gives a value in engineering units denoting the boundary between a significant and an insignificant change.
Calculate Derivative If Calculate Derivative is false, only Kc and Ti are calculated, and Td is set to zero. If Calculate Derivative is true, Kc, Ti, and Td are calculated. Safe Output Safe Output is a Mn value that will not cause any harm to a process. The default is to use the loop Mn value just prior to a tuning session start. High Stop If a PV goes above High Stop, Mn is set to Safe Output and an error is declared (see Table 9-4).

Documentation can also be exported by selecting File → Import Documentation from the menu. Using the Log Sheet The Log Sheet displays information about the devices such as address, tag, description, value, timestamp, and status. You can change the way the data is presented and determine your status - online or offline.
enter text in the address field. Entering an address creates an update of all other columns. You can enter a range of addresses by using the fill format equations below. Address\+-[count][\increment][\format] Address1-Address2[\increment][\format] Tag A tag is a very short description of an address and can be used in place of an address. Devices must exist if you want to edit this field. Tags are stored in database files containing addresses and their corresponding descriptions.
entire packet would have failed by including 1 erroneous address. Unlike SoftShop, ControlShop does not implement the type of error checking that would prevent a user from entering an invalid address so it is up to the PLC/device to report these types of errors. When offline, all the status rows will display the string “Offline”. This field is not displayed by default.
Destination can be in the form of an end address or a count. For example, a start address of 400001 and an end address of 400003 will display 400001, 400002, and 400003 in the log window. Selecting a count of 3 instead of an end address will give the same results. However, if increment is set to 2 and end address is selected addresses 400001 and 400003 will be displayed while addresses 400001, 400003, and 400005 will be displayed if count is selected.
Select All The “Select All” menu item under the main “Edit” menu can be used to unconditionally highlight all the rows in the active log window. Features such as delete, format, size, on, off, cut, copy, and paste can be performed on the entire log window. Log Status Window The log status window shown below lists successful and failed logs as well as any miscellaneous errors that may occur while attempting to log data (dependant upon setup criteria) for all log windows that are currently logging data.

If no items are checked in the group box, no action will be taken when the corresponding error situation arises.
FTTrend Overview FTTrend displays real-time data collected from multiple PLC devices or historical data collected from the FTLogger. This information is displayed in a graph with up to 256 points per graph. You can view different devices on the same graph and control how often the information is gathered and displayed. Creating a Trend Window To create a new Trend Window: • First launch FTTrender • Click menu.
Configuring FTTrend Devices Before any addresses can be inserted into a trend window, devices must be configured so that the servers know where to read the addresses. Selecting "Device Source…" from the Setup menu list does this. Only devices from “running” servers can be configured. Opening up a trend window starts a server for the selected server. Once a window is opened and the server starts running, it will continue to run throughout the duration of the application.
Figure 3 Within the “Select Configuration File” dialog, you can create a new configuration file or open up an existing one. If no configuration files exist, the “New File” radio button will be checked and the edit box within this group will hold a default configuration path and file. The path for the configuration file will default to the same path as the executable.
The list box within the “Existing File” group box will hold the most recently used (MRU) configuration files read from the registry similar to the MRU list of .LGR files under the “File” menu The database file must include at least 4 fields (ADDRESS, TAG, Description, and COMMENT) in order. If these fields are not found, a documentation-mapping dialog will be displayed to map user fields to FasTrak fields described above.
Figure 6 When “OK” is selected from the “Add Device” dialog, the configuration is sent to the server and a connection is made to the doc database file for reading and writing. If the database you are connecting to does not match specifications (i.e. there is a mismatch between table name or field names) then a dialog will be displayed to map specific fields so that the software knows where various types of documentation reside. This dialog is shown below.
