1: GENERAL INFORMATION Introduction This chapter describes general information for understanding the MicroSmart’s powerful capabilities and system setups to use the MicroSmart in various ways of communication. About the MicroSmart IDEC’s MicroSmart is a new family of micro programmable logic controllers available in two styles of CPU modules; allin-one and slim types.
1: GENERAL INFORMATION HMI Module (all CPU modules) An optional HMI module can be installed on any all-in-one type CPU module, and also on the HMI base module mounted next to any slim type CPU module. The HMI module makes it possible to manipulate the RAM data in the CPU module without using the Online menu options in WindLDR.
1: GENERAL INFORMATION Catch Input Four inputs can be used as catch inputs. The catch input makes sure to receive short input pulses (rising pulse of 40 µs or falling pulse of 150 µs minimum) from sensors without regard to the scan time. Interrupt Input Four inputs can be used as interrupt inputs. When a quick response to an external input is required, such as positioning control, the interrupt input can call a subroutine to execute an interrupt program.
1: GENERAL INFORMATION System Setup This section illustrates system setup configurations for using powerful communication functions of the MicroSmart. User Communication and Modem Communication System The all-in-one 16- and 24-I/O type MicroSmart CPU modules have port 1 for RS232C communication and port 2 connector. An optional RS232C or RS485 communication adapter can be installed on the port 2 connector.
1: GENERAL INFORMATION Computer Link System When the MicroSmart is connected to a computer, operating status and I/O status can be monitored on the computer, data in the CPU module can be monitored or updated, and user programs can be downloaded and uploaded.
1: GENERAL INFORMATION Data Link System With an optional RS485 communication adapter installed on the port 2 connector, one 16- or 24-I/O type CPU module at the master station can communicate with 31 slave stations through the RS485 line to exchange data and perform distributed control effectively. The RS485 terminals are connected with each other using a 2-core twisted pair cable. The same data link system can also be set up using any slim type CPU modules mounted with RS485 communication modules.
1: GENERAL INFORMATION Operator Interface Communication System The MicroSmart can communicate with IDEC’s HG series operator interfaces through RS232C port 1 and port 2. Optional cables are available for connection between the MicroSmart and HG series operator interfaces. When installing an optional RS232C communication adapter on the all-in-one type CPU module or an optional RS232C communication module on the slim type CPU module, two operator interfaces can be connected to one MicroSmart CPU module.
1: GENERAL INFORMATION AS-Interface Network Actuator-Sensor-Interface, abbreviated AS-Interface The MicroSmart can be connected to the AS-Interface network using the AS-Interface master module (FC4A-AS62M). AS-Interface is a type of field bus that is primarily intended to be used to control sensors and actuators. AS-Interface is a network system that is compatible with the IEC62026 standard and is not proprietary to any one manufacturer.

5: SPECIAL FUNCTIONS Interrupt Input All MicroSmart CPU modules have an interrupt input function. When a quick response to an external input is required, such as positioning control, the interrupt input can call a subroutine to execute an interrupt program. Four inputs I2 through I5 can be designated to execute interrupt at a rising and/or falling edge of input pulses.
5: SPECIAL FUNCTIONS Example: Interrupt Input The following example demonstrates a program of using the interrupt input function, with input I2 designated as an interrupt input. When the interrupt input is turned on, the input I0 status is immediately transferred to output Q0 using the IOREF (I/O refresh) instruction before the END instruction is executed. For the IOREF instruction, see page 18-5. MOV(W) S1 – 0 M8120 D1 – D8032 M8120 is the initialize pulse special internal relay.
5: SPECIAL FUNCTIONS Timer Interrupt In addition to the interrupt input as described in the preceding section, slim type CPU modules FC4A-D20RK1, FC4AD20RS1, FC4A-D40K1, and FC4A-D40S1 have a timer interrupt function. When a repetitive operation is required, the timer interrupt can be used to call a subroutine repeatedly at predetermined intervals of 10 through 140 ms.
5: SPECIAL FUNCTIONS Example: Timer Interrupt The following example demonstrates a program of using the timer interrupt function. The Function Area Settings must also be completed to use the timer interrupt function as described on the preceding page. MOV(W) S1 – 0 M8120 D1 – D8036 M8120 is the initialize pulse special internal relay. REP D8036 stores 0 to designate jump destination label 0 for timer interrupt.
5: SPECIAL FUNCTIONS Input Filter The input filter function is used to reject input noises. The catch input function described in the preceding section is used to read short input pulses to special internal relays. On the contrary, the input filter rejects short input pulses when the MicroSmart is used with input signals containing noises. Different input filter values can be selected for inputs I0 through I7 in four groups using the Function Area Settings.
5: SPECIAL FUNCTIONS User Program Protection The user program in the MicroSmart CPU module can be protected from reading, writing, or both using the Function Area Settings in WindLDR. The read/write protection can be temporarily disabled using a predetermined password. Upgraded CPU modules with system program version 210 or higher have an option for read protection without a password, making it possible to inhibit reading completely.
5: SPECIAL FUNCTIONS 4. When a password protect mode is selected, the Password Setting dialog box appears. Enter a password of 1 through 8 ASCII characters from the key board in the Password field, and enter the same password in the Confirm Password field. Click the OK button to return to the Others tab page. 5. Click the OK button and download the user program to the MicroSmart after changing any of these settings.
5: SPECIAL FUNCTIONS Constant Scan Time The scan time may vary whether basic and advanced instructions are executed or not depending on input conditions to these instructions. The scan time can be made constant by entering a required scan time preset value into special data register D8022 reserved for constant scan time. When performing accurate repetitive control, make the scan time constant using this function. The constant scan time preset value can be between 1 and 1,000 ms.
5: SPECIAL FUNCTIONS Partial Program Download Normally, the CPU module has to be stopped before downloading a user program. The all-in-one 16- and 24-I/O type CPU modules and all slim type CPU modules have run-time program download capabilities to download a user program containing small changes while the CPU is running in either 1:1 or 1:N computer link system. This function is particularly useful to make small modifications to the user program and to confirm the changes while the CPU is running.
5: SPECIAL FUNCTIONS Using Partial Program Download The partial program download function can download a maximum of 600 bytes (100 steps) of user program. When the modified rungs of the user program exceed 600 bytes, the partial program download cannot be used. Make sure that modification is within 600 bytes. When modifying two or more rungs of a user program, make sure that the difference between the first address and last address of the modifications is within 600 bytes (100 steps).
5: SPECIAL FUNCTIONS Analog Potentiometers The all-in-one 10- and 16-I/O type CPU modules and every slim type CPU module have one analog potentiometer. Only the 24-I/O type CPU module has two analog potentiometers. The values (0 through 255) set with analog potentiometers 1 and 2 are stored to data registers D8057 and D8058, respectively, and updated in every scan. The analog potentiometer can be used to change the preset value for a timer or counter.
5: SPECIAL FUNCTIONS Analog Voltage Input Every slim type CPU module has an analog voltage input connector. When an analog voltage of 0 through 10V DC is applied to the analog voltage input connector, the signal is converted to a digital value of 0 through 255 and stored to special data register D8058. The data is updated in every scan.
5: SPECIAL FUNCTIONS HMI Module This section describes the functions and operation of the optional HMI module (FC4A-PH1). The HMI module can be installed on any all-in-one type CPU module, and also on the HMI base module mounted next to any slim type CPU module.

7: BASIC INSTRUCTIONS Introduction This chapter describes programming of the basic instructions, available operands, and sample programs. All basic instructions are available on all MicroSmart CPU modules.
7: BASIC INSTRUCTIONS LOD (Load) and LODN (Load Not) The LOD instruction starts the logical operation with a NO (normally open) contact. The LODN instruction starts the logical operation with a NC (normally closed) contact. A total of eight LOD and/or LODN instructions can be programmed consecutively. Valid Operands Ladder Diagram Instruction LOD LODN I Q 0-307 0-307 M 0-1277 8000-8157 T C R 0-99 0-99 0-127 The valid operand range depends on the CPU module type.
7: BASIC INSTRUCTIONS Examples: LOD (Load), OUT (Output), and NOT Ladder Diagram Program List I0 Instruction LOD OUT LOD OUTN Q0 I1 Q1 Ladder Diagram Data I0 Q0 I1 Q1 I0 ON OFF I1 ON OFF Q0 ON OFF Q1 ON OFF Program List M2 Instruction LOD OUT Q0 Ladder Diagram Data M2 Q0 Program List Instruction LODN OUT Q1 Q0 Data Q0 Q1 Program List Ladder Diagram T0 Instruction LOD OUTN Q2 Ladder Diagram Data T0 Q2 Program List C1 SET Timing Chart Instruction LODN OUT Q10 Data C1 Q1
7: BASIC INSTRUCTIONS AND and ANDN (And Not) The AND instruction is used for programming a NO contact in series. The ANDN instruction is used for programming a NC contact in series. The AND or ANDN instruction is entered after the first set of contacts. Ladder Diagram I0 I0 Program List I1 Instruction LOD AND OUT LOD ANDN OUT Q0 I1 Q1 Timing Chart Data I0 I1 Q0 I0 I1 Q1 I0 ON OFF I1 ON OFF Q0 ON OFF Q1 ON OFF When both inputs I0 and I1 are on, output Q0 is on.
7: BASIC INSTRUCTIONS AND LOD (Load) The AND LOD instruction is used to connect, in series, two or more circuits starting with the LOD instruction. The AND LOD instruction is the equivalent of a “node” on a ladder diagram. When using WindLDR, the user need not program the AND LOD instruction. The circuit in the ladder diagram shown below is converted into AND LOD when the ladder diagram is compiled.
7: BASIC INSTRUCTIONS BPS (Bit Push), BRD (Bit Read), and BPP (Bit Pop) The BPS (bit push) instruction is used to save the result of bit logical operation temporarily. The BRD (bit read) instruction is used to read the result of bit logical operation which was saved temporarily. The BPP (bit pop) instruction is used to restore the result of bit logical operation which was saved temporarily. When using WindLDR, the user need not program the BPS, BRD, and BPP instructions.
7: BASIC INSTRUCTIONS TML, TIM, TMH, and TMS (Timer) Four types of timedown timers are available; 1-sec timer TML, 100-ms timer TIM, 10-ms timer TMH, and 1-ms timer TMS. A total of 32 timers (all-in-one 10-I/O type CPU module) or 100 timers (other CPU modules) can be programmed in a user program. Each timer must be allocated to a unique number T0 through T31 or T99. Timer Allocation Number Range Increments TML (1-sec timer) T0 to T99 0 to 65535 sec 1 sec TIM (100-ms timer) T0 to T99 0 to 6553.
7: BASIC INSTRUCTIONS Timer Circuit The preset value 0 through 65535 can be designated using a data register D0 through D1299 or D2000 through D7999; then the data of the data register becomes the preset value. Directly after the TML, TIM, TMH, or TMS instruction, the OUT, OUTN, SET, RST, TML, TIM, TMH, or TMS instruction can be programmed.
7: BASIC INSTRUCTIONS Timer Accuracy, continued Timer Counting Error Every timer instruction operation is individually based on asynchronous 16-bit reference timers. Therefore, an error occurs depending on the status of the asynchronous 16-bit timer when the timer instruction is executed.
7: BASIC INSTRUCTIONS CNT, CDP, and CUD (Counter) Three types of counters are available; adding (up) counter CNT, dual-pulse reversible counter CDP, and up/down selection reversible counter CUD. A total of 32 counters (all-in-one 10-I/O type CPU module) or 100 counters (other CPU modules) can be programmed in a user program. Each counter must be allocated to a unique number C0 through C31 or C99.
7: BASIC INSTRUCTIONS CDP (Dual-Pulse Reversible Counter) The dual-pulse reversible counter CDP has up and down pulse inputs, so that three inputs are required.

14: DATA CONVERSION INSTRUCTIONS BCNT (Bit Count) BCNT When input is on, bits which are on are sought in an array of consecutive bits starting at the point designated by source operand S1. Source operand S2 designates the quantity of bits searched. The quantity of bits which are on is stored to the destination designated by operand D1.
14: DATA CONVERSION INSTRUCTIONS ALT (Alternate Output) SOTU ALT D1 ***** When input is turned on, output, internal relay, or shift register bit designated by D1 is turned on and remains on after the input is turned off. When input is turned on again, the designated output, internal relay, or shift register bit is turned off. The ALT instruction must be used with a SOTU or SOTD instruction, otherwise the designated output, internal relay, or shift register bit repeats to turn on and off in each scan.
15: WEEK PROGRAMMER INSTRUCTIONS Introduction WKTIM instructions can be used as many as required to turn on and off designated outputs and internal relays at predetermined times and days of the week. Once the internal calendar/clock is set, the WKTIM instruction compares the predetermined time with the clock data in the clock cartridge. When the preset time is reached, internal relay or output designated as destination operand is turned on or off as scheduled. For setting the calendar/clock, see page 15-5.
15: WEEK PROGRAMMER INSTRUCTIONS S1 — Day of week comparison data (0 through 127) Specify the days of week to turn on the output or internal relay designated by D1. Day of Week Sunday Monday Tuesday Wednesday Thursday Friday Saturday 1 2 4 8 16 32 64 Value Designate the total of the values as operand S1 to turn on the output or internal relay. Example: To turn on the output on Mondays through Fridays, designate 62 as S1 because 2 + 4 + 8 + 16 + 32 = 62.
15: WEEK PROGRAMMER INSTRUCTIONS S1 through SN — Special month/day data Specify the months and days to add or skip days to turn on or off the comparison outputs programmed in WKTIM instructions. Month Day 01 through 12 01 through 31 Example: To set July 4 as a special day, designate 704 as S1. Make sure that the values set for S1 through SN are within the valid ranges.
15: WEEK PROGRAMMER INSTRUCTIONS • Keep Output ON across 0 a.m. When the hour/minute comparison data to turn on (S2) is larger than the hour/minute comparison data to turn off (S3), the comparison ON output (D1) turns on at S2 on the day designated by S1, remains on across 0 a.m., and turns off at S3 on the next day. This example demonstrates a program to keep the designated output on across 0 a.m. and turn off the output on the next day.
15: WEEK PROGRAMMER INSTRUCTIONS Setting Calendar/Clock Using WindLDR Before using the clock cartridge for the first time, the calendar/clock data in the clock cartridge must be set using WindLDR or executing a user program to transfer correct calendar/clock data from special data registers allocated to the calendar/ clock.

17: USER COMMUNICATION INSTRUCTIONS RS232C Line Control Signals While the MicroSmart is in the user communication mode, special data registers can be used to enable or disable DSR and DTR control signal options for port 2. Port 2 is available on the 16- and 24-I/O type CPU modules only, and an optional RS232C adapter must be installed on the port 2 connector to enable the RS232C communication. The DSR and DTR control signal options cannot be used for port 1. The RTS signal line of port 2 remains on.
17: USER COMMUNICATION INSTRUCTIONS DSR Input Control Signal Option D8105 Special data register D8105 is used to control data flow between the MicroSmart RS232C port 2 and the remote terminal depending on the DSR (data set ready) signal sent from the remote terminal. The DSR signal is an input to the MicroSmart to determine the status of the remote terminal. The remote terminal informs the MicroSmart using DSR whether the remote terminal is ready for receiving data or is sending valid data.
17: USER COMMUNICATION INSTRUCTIONS D8106 = 1: Whether the MicroSmart is running or stopped, DTR remains off. MicroSmart DTR signal D8106 = 2: Stopped Running Stopped ON OFF While the MicroSmart can receive data, DTR is turned on. While the MicroSmart can not receive data, DTR remains off. Use this option when flow control of receive data is required. Receive DTR signal D8106 = 3 or more: Impossible Possible Impossible ON OFF Same as D8106 = 0.

Use WindLDR ver. 4.40 or higher to program the new BCC. These block check characters are calculated as described below. ADD-2comp 1. Add the characters in the range from the BCC calculation start position to the byte immediately before the BCC. 2.
18: PROGRAM BRANCHING INSTRUCTIONS Introduction The program branching instructions reduce execution time by making it possible to bypass portions of the program whenever certain conditions are not satisfied. The basic program branching instructions are LABEL and LJMP, which are used to tag an address and jump to the address which has been tagged.
18: PROGRAM BRANCHING INSTRUCTIONS Example: LJMP and LABEL The following example demonstrates a program to jump to three different portions of program depending on the input. LJMP S1 0 When input I0 is on, program execution jumps to label 0. LJMP S1 1 When input I1 is on, program execution jumps to label 1. LJMP S1 2 When input I2 is on, program execution jumps to label 2. I0 I1 I2 END LABEL 0 M8121 is the 1-sec clock special internal relay.
18: PROGRAM BRANCHING INSTRUCTIONS LCAL (Label Call) LCAL When input is on, the address with label 0 through 127 designated by S1 is called. When input is off, no call takes place, and program execution proceeds with the next instruction. S1 ***** The LCAL instruction calls a subroutine, and returns to the main program after the branch is executed.
18: PROGRAM BRANCHING INSTRUCTIONS Correct Structure for Calling Subroutine When a LCAL instruction is executed, the remaining program instructions on the same rung may not be executed upon return, if input conditions are changed by the subroutine. After the LRET instruction of a subroutine, program execution begins with the instruction following the LCAL instruction, depending on current input condition.
18: PROGRAM BRANCHING INSTRUCTIONS IOREF (I/O Refresh) IOREF When input is on, 1-bit I/O data designated by source operand S1 is refreshed immediately regardless of the scan time. S1 ***** When I (input) is used as S1, the actual input status is immediately read into an internal relay starting with M300 allocated to each input available on the CPU module. When Q (output) is used as S1, the output data in the RAM is immediately written to the actual output available on the CPU module.
18: PROGRAM BRANCHING INSTRUCTIONS Example: IOREF The following example demonstrates a program to transfer the input I0 status to output Q0 using the IOREF instruction. Input I2 is designated as an interrupt input. For the interrupt input function, see page 5-20. MOV(W) M8120 S1 – 0 D1 – D8032 REP M8120 is the initialize pulse special internal relay. D8032 stores 0 to designate jump destination label 0 for interrupt input I2.
18: PROGRAM BRANCHING INSTRUCTIONS DI (Disable Interrupt) DI When input is on, interrupt inputs and timer interrupt designated by source operand S1 are disabled. S1 ** EI (Enable Interrupt) EI When input is on, interrupt inputs and timer interrupt designated by source operand S1 are enabled.
18: PROGRAM BRANCHING INSTRUCTIONS Example: DI and EI The following example demonstrates a program to disable and enable interrupt inputs and timer interrupt selectively. For the interrupt input and timer interrupt functions, see pages 5-20 and 5-22. In this example, inputs I2 and I3 are designated as interrupt inputs and timer interrupt is used with interrupt intervals of 100 ms.
19: COORDINATE CONVERSION INSTRUCTIONS Introduction The coordinate conversion instructions convert one data point to another value, using a linear relationship between values of X and Y. Y (X2, Y2) (X1, Y1) X (X0, Y0) Upgrade Information Upgraded CPU modules can use an expanded range of X and Y values. Word and integer data types can be designated for the Y values. Applicable CPU modules and system program version are shown in the table below.
19: COORDINATE CONVERSION INSTRUCTIONS Xn (X value), Yn (Y value) Enter values for the X and Y coordinates. Three different data ranges are available depending on the system program version and the data type.
19: COORDINATE CONVERSION INSTRUCTIONS S1 (Format number) Select a format number 0 through 5 which have been set using the XYFS instruction. When an XYFS instruction with the corresponding format number is not programmed, or when XYFS and CVXTY instructions of the same format number have different data type designations, a user program execution error will result, turning on special internal relay M8004 and the ERR LED.
19: COORDINATE CONVERSION INSTRUCTIONS Valid Operands Operand Function S1 (Source 1) Format number — — — — — — — I Q M R T C D Constant Repeat 0 to 5 — S2 (Source 2) Y value X X X X X X X 0 to 65535 –32768 to 32767 — D1 (Destination 1) Destination to store results — X ▲ X X X X — — For the valid operand number range, see pages 6-1 and 6-2. ▲ Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.
19: COORDINATE CONVERSION INSTRUCTIONS Example: Linear Conversion The following example demonstrates setting up two coordinate points to define the linear relationship between X and Y. The two points are (X0, Y0) = (0, 0) and (X1, Y1) = (8000, 4000). Once these are set, there is an X to Y conversion, as well as a Y to X conversion. XYFS(I) X0 0 Y0 0 CVXTY(I) S1 0 S2 D10 D1 D20 When input I0 is on, CVXTY converts the value in D10 and stores the result in D20.
19: COORDINATE CONVERSION INSTRUCTIONS Example: Overlapping Coordinates In this example, the XYFS instruction sets up three coordinate points, which define two different linear relationships between X and Y. The three points are: (X0, Y0) = (0, 100), (X1, Y1) = (100, 0), and (X2, Y2) = (300, 100). The two line segments define overlapping coordinates for X. That is, for each value of Y within the designated range, there would be two X values assigned.
20: PULSE INSTRUCTIONS Introduction The PULS (pulse output) instruction is used to generate pulse outputs of 10 Hz through 20,000 Hz which can be used to control pulse motors for simple position control applications. The PWM (pulse width modulation) instruction is used to generate pulse outputs of 6.81, 27.26, or 217.86 Hz with a variable pulse width ratio between 0% and 100%, which can be used for illumination control.
20: PULSE INSTRUCTIONS Valid Operands Operand Function C D Constant Repeat S1 (Source 1) Control register — — — — — — I Q M X — — D1 (Destination 1) Status relay — — — — — — — — X R T Source operand S1 (control register) uses 8 data registers starting with the operand designated as S1. Data registers D0 through D1292 and D2000 through D7992 can be designated as S1. For details, see the following pages.
20: PULSE INSTRUCTIONS S1+2 Pulse Counting Pulse counting can be enabled for the PULS1 instruction only. With pulse counting enabled, PULS1 generates a predetermined number of output pulses as designated by operands S1+3 and S1+4. With pulse counting disabled, PULS1 or PULS2 generates output pulses while the start input for the PULS instruction remains on. 0: Disable pulse counting 1: Enable pulse counting (PULS1 only) When programming PULS2, store 0 to the data register designated by S1+2.
20: PULSE INSTRUCTIONS D1+1 Pulse Output Complete The internal relay designated by operand D1+1 turns on when the PULS1 instruction has completed generating a predetermined number of output pulses or when either PULS instruction is stopped to generate output pulses. When the start input for the PULS instruction is turned on, the internal relay designated by operand D1+1 turns off.
20: PULSE INSTRUCTIONS Timing Chart for Disable Pulse Counting This program demonstrates a timing chart of the PULS2 instruction without pulse counting. I1 PULS 2 S1 D100 D1 M20 D102 = 0 (disable pulse counting) Start Input I1 Output Pulse Frequency D101 FR1 FR2 FR3 Output Pulse Q1 FR1 FR2 Pulse Output ON M20 Pulse Output Complete M21 • When input I1 is turned on, PULS2 starts to generate output pulses at the frequency designated by the value stored in data register D101.
20: PULSE INSTRUCTIONS Sample Program: PULS1 This program demonstrates a user program of the PULS1 instruction to generate 1,000 pulses at a frequency of 3 kHz from output Q0, followed by 3,000 pulses at a frequency of 5 kHz.
20: PULSE INSTRUCTIONS PWM1 (Pulse Width Modulation 1) PWM 1 S1 D1 ***** ***** When input is on, the PWM1 instruction generates a pulse output. The output pulse frequency is selected from 6.81, 27.26, or 217.86 Hz, and the output pulse width ratio is determined by source operand S1. PWM1 sends out output pulses from output Q0. PWM1 can be programmed to generate a predetermined number of output pulses.
20: PULSE INSTRUCTIONS S1+0 Output Pulse Frequency The value stored in the data register designated by operand S1+0 determines the pulse output frequency. 0: 6.81 Hz (146.84 ms period) 1: 27.26 Hz (36.68 ms period) 2: 217.86 Hz (4.59 ms period) S1+1 Pulse Width Ratio The value stored in the data register designated by operand S1+1 specifies the pulse width ratio of the pulse output in percent of the period determined by the output pulse frequency selected with S1+0.
20: PULSE INSTRUCTIONS Destination Operand D1 (Status Relay) Three internal relays starting with the operand designated by D1 indicate the status of the PWM instruction. These operands are for read only.
20: PULSE INSTRUCTIONS Timing Chart for Enable Pulse Counting This program demonstrates a timing chart of the PWM1 instruction when pulse counting is enabled.

21: PID INSTRUCTION Introduction The PID instruction implements a PID (proportional, integral, and derivative) algorithm with built-in auto tuning to determine PID parameters, such as proportional gain, integral time, derivative time, and control action automatically.
21: PID INSTRUCTION PID (PID Control) PID S1 S2 S3 S4 D1 ***** ***** ***** ***** ***** When input is on, auto tuning and/or PID action is executed according to the value (0 through 2) stored in a data register operand assigned for operation mode. Applicable CPU Modules and Quantity of PID Instructions A maximum of 8 or 14 PID instructions can be used in a user program, depending on the CPU module type.
21: PID INSTRUCTION Source Operand S1 (Control Register) Store appropriate values to data registers starting with the operand designated by S1 before executing the PID instruction as required, and make sure that the values are within the valid range. Operands S1+0 through S1+2 are for read only, and operands S1+23 through S1+26 are reserved for the system program.
21: PID INSTRUCTION S1+0 Process Variable (after conversion) When the linear conversion is enabled (S1+4 set to 1), the data register designated by S1+0 stores the linear conversion result of the process variable (S4). The process variable (S1+0) takes a value between the linear conversion minimum value (S1+6) and the linear conversion maximum value (S1+5). When the linear conversion is disabled (S1+4 is set to 0), the data register designated by S1+0 stores the same value as the process variable (S4).
21: PID INSTRUCTION S1+3 Operation Mode When the start input for the PID instruction is turned on, the CPU module checks the value stored in the data register designated by S1+3 and executes the selected operation. The selection cannot be changed while executing the PID instruction. 0: PID action The PID action is executed according to the designated PID parameters such as proportional gain (S1+7), integral time (S1+8), derivative time (S1+9), and control action (S2+0).
21: PID INSTRUCTION Example: When type K thermocouple is connected, the analog input data ranges from 0 through 4095. To convert the analog input data to actual measured temperature values, set the following parameters.
21: PID INSTRUCTION When the derivative time is set to a large value, the derivative action becomes large. When the derivative action is too large, hunching of a short period is caused. While the PID action is in progress, the derivative time value can be changed by the user. S1+10 Integral Start Coefficient The integral start coefficient is a parameter to determine the point, in percent of the proportional term, where to start the integral action.
21: PID INSTRUCTION Example – Sampling period: 80 ms, Scan time: 60 ms (Sampling period > Scan time) 1 scan 1 scan 1 scan 60 ms PID Executed 1 scan 60 ms PID Not Executed 60 ms 60 ms PID Executed 1 scan 1 scan 60 ms PID Executed 60 ms PID Executed (120 ms) (100 ms) 80 ms 40 ms 20 ms 0 ms 1 scan 1 scan 60 ms PID Not Executed 60 ms 60 ms PID Executed PID Executed (120 ms) (100 ms) 40 ms 20 ms S1+13 Control Period The control period determines the duration of the ON/OFF cycle of th
21: PID INSTRUCTION S1+16 Output Manipulated Variable Upper Limit The value contained in the data register designated by S1+16 specifies the upper limit of the output manipulated variable (S1+1) in two ways: direct and proportional. S1+16 Value 0 through 100 When S1+16 contains a value 0 through 100, the value directly determines the upper limit of the output manipulated variable (S1+1).
21: PID INSTRUCTION Set the AT sampling period to a long value to make sure that the current process variable is smaller than or equal to the previous process variable during direct control action (S2+0 is on) or that the current process variable is larger than or equal to the previous process variable during reverse control action (S2+0 is off). S1+20 AT Control Period The AT control period determines the duration of the ON/OFF cycle of the control output (S2+6) during auto tuning.
21: PID INSTRUCTION Source Operand S2 (Control Relay) Turn on or off appropriate outputs or internal relays starting with the operand designated by S2 before executing the PID instruction as required. Operands S2+4 through S2+7 are for read only to reflect the PID and auto tuning statuses.
21: PID INSTRUCTION S2+2 Output Manipulated Variable Limit Enable The output manipulated variable upper limit (S1+16) and the output manipulated variable lower limit (S1+17) are enabled or disabled using the output manipulated variable limit enable control relay (S2+2). To enable the output manipulated variable upper/lower limits, turn on S2+2. To disable the output manipulated variable upper/lower limits, turn off S2+2.
21: PID INSTRUCTION Source Operand S4 (Process Variable before Conversion) The PID instruction is designed to use analog input data from an analog I/O module as process variable. The analog I/O module converts the input signal to a digital value of 0 through 4095, and stores the digital value to a data register depending on the mounting position of the analog I/O module and the analog input channel connected to the analog input source.
21: PID INSTRUCTION Application Example This application example demonstrates a PID control for a heater to keep the temperature at 200°C. In this example, when the program is started, the PID instruction first executes auto tuning according to the designated AT parameters, such as AT sampling period, AT control period, AT set point, and AT output manipulated variable, and also the temperature data inputted to the analog input module.

Using the modem mode, the MicroSmart can initialize a modem, dial a telephone number, send an AT command, enable the answer mode to wait for an incoming call, and disconnect the telephone line. These operations can be performed simply by turning on a start internal relay dedicated to each operation.
27: MODEM MODE Applicable Modems Any Hayes compatible modem can be used. Modems with a communications rate of 9600 bps or more between modems are recommended. Use modems of the same make and model at both ends of the communication line. Special Internal Relays for Modem Mode Special internal relays M8050-M8077 are allocated to the modem mode. M8050-M8056 are used to send an AT command or disconnect the telephone line. M8060-M8066 and M8070-M8076 turn on to indicate the results of the command.
27: MODEM MODE Special Data Registers for Modem Mode Special data registers D8103 and D8109-D8199 are allocated to the modem mode. When the MicroSmart starts to run, D8109 and D8110 store the default values, and D8145-D8169 store the default initialization string.
27: MODEM MODE AT and LF are appended at the beginning and end of the initialization string automatically by the system program and are not stored in data registers. DR 8145 8146 8147 8148 8149 8150 8151 8152 8153 8154 8155 8156 8157 8158 8159 8160 8161 AT E0 Q0 V1 &D 2& C1 \V 0X 4& K3 \A 0\ N5 S0 =2 &W 0D00 LF Depending on your modem and telephone line, the initialization string may have to be modified. Consult the manual for your modem.
27: MODEM MODE As described above, when start internal relay M8050 is turned on, the initialization string is sent, followed by the ATZ command and the dial command. When start internal relay M8051 is turned on, the ATZ command is sent, followed by the dial command. The dial command can also be sent separately by turning on start internal relay M8052.
27: MODEM MODE Example of AT Command: ATE0Q0V1 CR LF AT and LF are appended at the beginning and end of the AT general command string automatically by the system program and need not be stored in data registers. To program the AT command string of the example above, store the command characters and ASCII value 0Dh for CR to data registers starting with D8130.
27: MODEM MODE Modem Mode Status Data Register When the modem mode is enabled, data register D8111 stores a modem mode status or error code. D8111 Value 0 Status Description Not in the modem mode Modem mode is not enabled. 10 Ready for connecting line Start internal relays except for disconnecting line can be turned on.
27: MODEM MODE Initialization String Commands The built-in initialization string (see page 27-3) include the commands shown below. For details of modem commands, see the user’s manual for your modem. When you make an optional initialization string, modify the initialization string to match your modem. E0 Characters NOT echoed. The modem mode of the MicroSmart operates without echo back. Without the E0 command, the MicroSmart misunderstands an echo for a result code.
27: MODEM MODE Preparation for Using Modem Before using a modem, read the user’s manual for your modem. The required initialization string depends on the model and make of the modem. When the MicroSmart starts to run the user program, the default modem initialization strings is stored to D8145-D8169. See page 27-3.
27: MODEM MODE Programming WindLDR The Communication page in the Function Area Settings must be programmed to enable the modem communication for port 2. If required, communication parameters of the CPU module port 2 can also be changed. Since these settings relate to the user program, the user program must be downloaded to the MicroSmart after changing any of these settings. 1. From the WindLDR menu bar, select Configure > Function Area Settings. The Function Area Setting dialog box appears. 2.
27: MODEM MODE Operating Procedure for Modem Mode 1. After completing the user program including the Function Area Settings, download the user program to the MicroSmart from a computer running WindLDR. 2. Start the MicroSmart to run the user program. 3. Turn on start internal relay M8050 or M8055 to initialize the modem. When originating the modem communication, turn on M8050 to send the initialization string, the ATZ command, and the dial command.
27: MODEM MODE Sample Program for Modem Originate Mode This program demonstrates a user program for the modem originate mode to move values to data registers assigned to the modem mode, initialize the modem, dial the telephone number, and disconnect the telephone line. While the telephone line is connected, user communication instruction TXD2 sends a character string “Connect.
27: MODEM MODE Sample Program for Modem Answer Mode This program demonstrates a user program for the modem answer mode to move a value to a data register assigned to the modem mode and initialize the modem. While the telephone line is connected, user communication instruction RXD2 is executed to receive an incoming communication. M8120 is the initialize pulse special internal relay.
27: MODEM MODE Troubleshooting in Modem Communication When a start internal relay is turned on, the data of D8111 (modem mode status) changes, but the modem does not work. Cause: A wrong cable is used or wiring is incorrect. Solution: Use the modem cable 1C (FC2A-KM1C). The DTR or ER indicator on the modem does not turn on. Cause: A wrong cable is used or wiring is incorrect. Solution: Use the modem cable 1C (FC2A-KM1C).
28: AS-INTERFACE MASTER COMMUNICATION Introduction This chapter describes general information about the Actuator-Sensor-Interface, abbreviated AS-Interface, and detailed information about using the AS-Interface master module. About AS-Interface AS-Interface is a type of field bus that is primarily intended to be used to control sensors and actuators. AS-Interface is a network system that is compatible with the IEC62026 standard and is not proprietary to any one manufacturer.
28: AS-INTERFACE MASTER COMMUNICATION AS-Interface System Requirements Master The AS-Interface master controls and monitors the status of slave devices connected to the AS-Interface bus. Normally, the AS-Interface master is connected to a PLC (sometimes called ‘host’) or a gateway. For example, the MicroSmart AS-Interface master module is connected to the MicroSmart CPU module. The FC4A MicroSmart CPU module can be used with one AS-Interface master module to set up one AS-Interface network.
28: AS-INTERFACE MASTER COMMUNICATION AS-Interface Power Supply The AS-Interface bus uses a dedicated 30V DC power supply (AS-Interface power supply), which is indicated with the AS-Interface mark. General-purpose power supply units cannot be used for the AS-Interface bus. AS-Interface Marks Caution • Use a VLSV (very low safety voltage) to power the AS-Interface bus. The normal output voltage of the AS-Interface power supply is 30V DC.
28: AS-INTERFACE MASTER COMMUNICATION Main Features of AS-Interface V2 with Slave Expansion Capability The AS-Interface is a reliable bus management system in which one master periodically monitors each slave device connected on the AS-Interface bus in sequence. The master manages the I/O data, parameters, and identification codes of each slave in addition to slave addresses.
28: AS-INTERFACE MASTER COMMUNICATION Quantities of Slaves and I/O Points The quantity of slaves that can be connected to one AS-Interface master module is as follows. • Standard slaves: 31 maximum • A/B slaves: 62 maximum The limits for slave quantities given above apply when the slaves are either all standard slaves or are all A/B slaves.
28: AS-INTERFACE MASTER COMMUNICATION Operation Basics This section describes simple operating procedures for the basic AS-Interface system from programming WindLDR on a computer to monitoring the slave operation. AS-Interface System Setup The sample AS-Interface system consists of the following devices: Name Type No. Description FC4A MicroSmart Slim Type CPU Module FC4A-D20RK1 — MicroSmart AS-Interface Master Module FC4A-AS62M — WindLDR FC9Y-LP2CDW Version 5.
28: AS-INTERFACE MASTER COMMUNICATION Power Supply Caution • When turning off the power to the CPU module, also turn off the AS-Interface power supply. If the CPU module is powered down and up while the AS-Interface power remains on, AS-Interface communication may stop due to a configuration error, resulting in a communication error. • Turn on the AS-Interface power supply no later than the CPU module power supply, except when slave address 0 exists on the network.
28: AS-INTERFACE MASTER COMMUNICATION Selecting the PLC Type Start WindLDR on a computer. 1. From the WindLDR menu bar, select Configure > PLC Selection. The PLC Selection dialog box appears. 2. Select FC4A-D20R. 3. Click OK to save changes and return to the ladder editing screen. Function Area Settings Use of the AS-Interface master module must be selected in the Function Area Settings dialog box. 1. From the WindLDR menu bar, select Configure > Function Area Settings.
28: AS-INTERFACE MASTER COMMUNICATION Assigning a Slave Address AS-Interface compatible slave devices are set to address 0 at factory. Connect the slave to the AS-Interface master module as shown on page 28-6. Do not connect two or more slaves with slave address 0, otherwise the AS-Interface master module cannot recognize slave addresses correctly. 1. Power up the MicroSmart CPU module first. Approximately 5 seconds later, turn on the AS-Interface power supply.
28: AS-INTERFACE MASTER COMMUNICATION Configuring a Slave Next, you have to set the slave configuration in the AS-Interface master module, either by using pushbuttons PB1 and PB2 on the AS-Interface master module or WindLDR.

Check that PWR LED and CMO LED on the AS-Interface master module are on (normal protected mode). 2. Press pushbuttons PB1 and PB2 together for 3 seconds.
28: AS-INTERFACE MASTER COMMUNICATION Configuration Using WindLDR Slave configuration can be set using WindLDR in two ways; using the Auto Configuration or Manual Configuration button on the Configure AS-Interface Master dialog box. 1. Click the Auto Configuration button to store the configuration information (LDS, CDI, PI) of the connected slaves to the EEPROM (LPS, PCD, PP) in the AS-Interface master module. For details, see page 28-32.
28: AS-INTERFACE MASTER COMMUNICATION Monitoring Digital I/O, and Changing Output Status and Parameters While the MicroSmart is communicating with AS-Interface slaves through the AS-Interface bus, operating status of ASInterface slaves can be monitored using WindLDR on a computer. Output statuses and parameter image (PI) of slaves connected to the AS-Interface master module can also be changed using WindLDR. 1. From the WindLDR menu bar, select Online > Monitor.
28: AS-INTERFACE MASTER COMMUNICATION Troubles at System Start-up The following table summarizes possible troubles at system start-up, probable causes and actions to be taken. Trouble Cause and Action • AS-Interface power is not supplied to the AS-Interface master module. Check that PWR LED is off. (power) wiring is correct and AS-Interface power is supplied. • Power is not supplied from the CPU module to the AS-Interface master module.
28: AS-INTERFACE MASTER COMMUNICATION Pushbuttons and LED Indicators This section describes the operation of pushbuttons PB1 and PB2 on the AS-Interface master module to change operation modes, and also explains the functions of address and I/O LED indicators. Pushbutton Operation The operations performed by pushbuttons PB1 and PB2 on the front of the AS-Interface master module depend on the duration of being pressed.
28: AS-INTERFACE MASTER COMMUNICATION AS-Interface Master Module Operation Modes The AS-Interface master module has two modes of operation: connected mode is used for actual operation, and local mode is used for maintenance purposes. Connected Mode In connected mode, the CPU module communicates with the AS-Interface master module to monitor and control each slave. Connected mode is comprised of the following three modes.
28: AS-INTERFACE MASTER COMMUNICATION LED Indicators The LED indicators on the AS-Interface master module consist of status LEDs, I/O LEDs, and address LEDs. Address LEDs (0x to 3x) Status LEDs Address LEDs (x0 to x9) Input LEDs Output LEDs Address LEDs (A and B) LED Indicators Description PWR (AS-Interface power supply) Indicates the status of the AS-Interface power supply for the AS-Interface master module. Goes on when the AS-Interface power is supplied sufficiently.
28: AS-INTERFACE MASTER COMMUNICATION Status LEDs The operation modes of the AS-Interface master module can be changed by pressing the pushbuttons on the front of the AS-Interface master module or by executing ASI commands. The operation modes can be confirmed on the six status LEDs on the AS-Interface master module. For details about the ASI commands, see page 28-28.
28: AS-INTERFACE MASTER COMMUNICATION AS-Interface Operands This chapter describes AS-Interface operands, or internal relays M1300 through M1997 and data registers D1700 through D1999, assigned in the CPU module to control and monitor the AS-Interface bus, and provides detailed description about internal relays allocated to SwitchNet™ control units for use as slaves in the AS-Interface network.
28: AS-INTERFACE MASTER COMMUNICATION I/O Data for AS-Interface Master Module The AS-Interface master module can process digital I/O data and analog I/O data. Digital I/O data can be a maximum of 4 digital inputs and 4 digital outputs per slave. Analog I/O data consists of 4 channels of 16-bit analog input or output data per slave.
28: AS-INTERFACE MASTER COMMUNICATION • Digital Output Data Image Data Format Output Data Image (ODI) 7 (DO3) 6 (DO2) 5 (DO1) 4 (DO0) 3 (DO3) 2 (DO2) 1 (DO1) M1620 Byte 0 Slave 1(A) (Slave 0) M1630 Byte 1 Slave 3(A) Slave 2(A) M1640 Byte 2 Slave 5(A) Slave 4(A) M1650 Byte 3 Slave 7(A) Slave 6(A) M1660 Byte 4 Slave 9(A) Slave 8(A) M1670 Byte 5 Slave 11(A) Slave 10(A) M1680 Byte 6 Slave 13(A) Slave 12(A) M1690 Byte 7 Slave 15(A) Slave 14(A) M1700 Byte 8 Slave 17(A) S
28: AS-INTERFACE MASTER COMMUNICATION Analog I/O Data of Analog Slaves The I/O data for a maximum of seven analog slaves (four channels for each slave) on the AS-Interface bus is stored to ASInterface data registers in the CPU module. The analog slave addresses (1 to 31) are in the ascending order. The input data for each analog slave is allocated to data registers D1700 to D1731, and the output data is allocated to D1732 to D1763. The AS-Interface master module is compliant with analog slave profile 7.3.
28: AS-INTERFACE MASTER COMMUNICATION • Analog Output Data Analog Output Channel No.
28: AS-INTERFACE MASTER COMMUNICATION Status Information The status information is allocated to AS-Interface internal relays M1940 through M1997. These internal relays are used to monitor the status of the AS-Interface bus. If an error occurs on the bus, you can also confirm the error with the status LEDs on the front of the AS-Interface master module in addition to these status internal relays.
28: AS-INTERFACE MASTER COMMUNICATION M1943 Auto_Address_Available M1943 indicates whether or not the conditions for the auto addressing function are satisfied. M1943 goes on when the auto addressing function is enabled and there is one faulty slave (a slave which cannot be recognized by the AS-Interface master module) on the AS-Interface bus. M1944 Configuration M1944 indicates whether the AS-Interface master module is in configuration mode (on) or other mode (off).
28: AS-INTERFACE MASTER COMMUNICATION Slave List Information Data registers D1764 through D1779 are assigned to slave list information to determine the operating status of the slaves. The slave list information is grouped into four lists. List of active slaves (LAS) shows the slaves currently in operation. List of detected slaves (LDS) the slaves detected on the AS-Interface bus. List of peripheral fault slaves (LPF) the faulty slaves.
28: AS-INTERFACE MASTER COMMUNICATION Slave Identification Information (Slave Profile) Data registers D1780 through D1940 are assigned to the slave identification information, or the slave profile. The slave profile includes configuration data and parameters to indicate the slave type and slave operation, respectively. Configuration Data Image (CDI) Data registers D1780 through D1843 are allocated to read the CDI of each slave.
28: AS-INTERFACE MASTER COMMUNICATION Parameter Image (PI) Data registers D1908 through D1923 are allocated to read the PI of each slave. The PI is made up of four parameters: the P3, P2, P1, and P0. The PI is the current slave parameter data collected by the AS-Interface master module at power-up and stored in the AS-Interface master module. To change the PI settings, use WindLDR (Slave Status dialog box) or execute the ASI command Change Slave PI.
28: AS-INTERFACE MASTER COMMUNICATION ASI Commands The ASI commands are used to update AS-Interface operands in the CPU module or to control the AS-Interface master module. Data registers D1941 through D1944 are used to store command data. D1945 is used to store a request code before executing the command. While the command is executed, D1945 stores status and result codes.
28: AS-INTERFACE MASTER COMMUNICATION Request and Result Codes D1945 Value Low Byte Description Note 00h Initial value at power up 01h Request 02h Processing ASI command 04h Completed normally 08h (Executing configuration) 14h Peripheral device failure 24h ASI command error 74h Impossible to execute 84h Execution resulting in error While D1945 lower byte stores 01h, 02h, or 08h, do not write any value to D1945, otherwise the ASI command is not executed correctly.
28: AS-INTERFACE MASTER COMMUNICATION Using WindLDR This section describes the procedures to use WindLDR for the AS-Interface system. WindLDR contains the Configure ASInterface Master dialog box to configure slaves and to change slave addresses, and the Monitor AS-Interface Slave dialog box to monitor the slave operation. For the procedures to select the PLC type and Function Area Settings, see page 28-8.
28: AS-INTERFACE MASTER COMMUNICATION Slave Address Shading Colors Operating status of the slave can be confirmed by viewing the shading color at the slave address on the Configure ASInterface Master dialog box. The screen display can be updated by clicking the Refresh button. Address Shading Description LAS LDS LPF LPS List of active slaves List of detected slaves List of peripheral fault slaves List of projected slaves No Shade The slave is not recognized by the master.
