3 Safety Precautions

!WARNING Connect the ground terminal of the Power Supply Unit (CPM2C-PA201) to a
ground or 100 or less. Not doing so may result in electric shock.
!WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing
so may result in electric shock.
!WARNING Do not touch any of the terminals or terminal blocks while the power is being
supplied. Doing so may result in electric shock.
!WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do
so may result in malfunction, fire, or electric shock.
!WARNING Provide safety measures in external circuits (i.e., not in the Programmable
Controller), including the following items, in order to ensure safety in the sys­tem if an abnormality occurs due to malfunction of the PC or another external factor affecting the PC operation. Not doing so may result in serious acci­dents.
xvi
Safety Precautions 3
• Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits.
• The PC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system.
• The PC outputs may remain ON or OFF due to deposition or burning of the output relays or destruction of the output transistors. As a counter­measure for such problems, external safety measures must be provided to ensure safety in the system.
• If the 24-VDC output (service power supply) of the Power Supply Unit (CPM2C-PA201) is overloaded or shorted, the voltage may drop causing outputs to turn OFF. External safety measures must be provided to ensure safety in the system in such an event.
!WARNING When handling the Memory Backup Battery, never drop, disassemble, distort,
short-circuit, recharge, heat to a temperature exceeding 100°C, or throw into fire. Otherwise the Battery may explode, catch fire, or leak fluid.
!WARNING When transferring programs to other nodes, or when making changes to I/O
memory, confirm the safety of the destination node before transfer. Not doing so may result in injury.
!Caution Execute online edit only after confirming that no adverse effects will be
caused by extending the cycle time. Otherwise, the input signals may not be readable.
!Caution Tighten the screws on the terminal block of the Power Supply Unit (CPM2C-
PA201) to a torque of 0.74 to 0.9 N•m. Loose screws may result in burning or malfunction.
!Caution Do not connect the 24-VDC output (service power supply) or the Power Sup-
ply Unit (CPM2C-PA201) to an AC power supply. Connecting it to an AC power supply will damage the internal circuit.
!Caution When connecting a personal computer or other peripheral device to the
CPM2C-S, either ground the 0 V side of the CPM2C-S or do not ground at all. Depending on the method of grounding, the 24-V power supply may short-cir­cuit; do not ground the 24-V side as shown in the following diagram.

• Fail-safe measures must be taken by the customer to ensure safety in the event of incorrect, missing, or abnormal signals caused by broken signal lines, momentary power interruptions, or other causes.
• Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits.
• Construct a control circuit so that power supply for the I/O circuits does not come ON before power supply for the Unit. If power supply for the I/O circuits comes ON before power supply for the Unit, normal operation may be temporarily interrupted.
• If the operating mode is changed from RUN or MONITOR mode to PRO­GRAM mode, with the IOM Hold Bit ON, the output will hold the most recent status. In such a case, ensure that the external load does not exceed specifications. (If operation is stopped because of an operation error (including FALS instructions), the values in the internal memory of the CPU Unit will be saved, but the outputs will all turn OFF.)
• Install the CPM2C-S and Expansion I/O Units properly so that they will not fall off.
• Be sure that the terminal blocks and other items with locking devices are properly locked into place. Improper locking may result in malfunction.
• Be sure that terminal blocks and connectors are connected in the speci­fied direction with the correct polarity. Not doing so may result in malfunc­tion.
• Use the Unit with the battery housing cover in place to prevent dust or for­eign matter from entering inside the Unit. Not doing so may result in mal­function.
• Install the expansion I/O connector cover to the last Unit (Expansion Unit or Expansion I/O Unit) to prevent dust or foreign matter from entering inside the Unit. Not doing so may result in malfunction.
• Be sure to attach the labels supplied with the CPM2C-S or provide other protective covers when wiring in order to prevent dust or wiring cuttings from entering the Unit.
• Remove the label after the completion of wiring to ensure proper heat dis­sipation. Leaving the label attached may result in malfunction.
• Use round crimp terminals for wiring the Power Supply Unit (CPM2C­PA201). Do not connect bare stranded wires directly to terminals. Con­nection of bare stranded wires may result in burning.
• Be sure to perform wiring in accordance with the CPM2C-S Operation Manual. Incorrect wiring may result in burning.
• Do not apply voltages to the input terminals in excess of the rated input voltage. Excess voltages may result in burning.
• Do not apply voltages or connect loads to the output terminals in excess of the maximum switching capacity. Excess voltage or loads may result in burning.
• Install external breakers and take other safety measures against short-cir­cuiting in external wiring. Insufficient safety measures against short-cir­cuiting may result in burning.
• Always use the power supply voltage specified in the operation manuals. An incorrect voltage may result in malfunction or burning.
xix
EC Directives 6
• In areas with an unreliable power supply, install devices that will ensure a reliable power supply within the rated voltage and frequency ranges.
• Check the user program for proper execution before actually running it on the Unit. Not checking the program may result in an unexpected opera­tion.
• Double-check all wiring and switch settings before turning ON the power supply. Incorrect wiring or switch settings may result in burning.
• Confirm that no adverse effect will occur in the system before attempting any of the following. Not doing so may result in an unexpected operation.
• Changing the operating mode of the PC.
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• Before touching the Unit, be sure to first touch a grounded metallic object in order to discharge any static built-up. Not doing so may result in mal­function or damage.
• Do not pull on the cables or bend the cables beyond their natural limit. Doing either of these may break the cables.
• Do not apply forces exceeding 50 N to connector sections.
• Do not place objects on top of the cables. Doing so may break the cables.
• Resume operation only after transferring to the new CPU Unit the con­tents of the DM and HR Areas required for resuming operation. Not doing so may result in an unexpected operation.
• When handling the battery, never short-circuit, recharge, disassemble, heat excessively, incinerate, or subject the battery to excessive force. Subjecting the battery to excessive forces such as dropping the battery on the floor can cause the battery to leak.
• Install the Unit properly as specified in the operation manual. Improper installation of the Unit may result in malfunction.
• When transporting the Units, use special packing boxes. Be careful not to apply excessive vibration or shock during transportation and not to drop the product.
• Store the Units within the following temperature and humidity ranges: Storage temperature: –20 to 75°C, storage humidity: 10% to 90% (with no icing or condensation)

6 EC Directives

6-1 Applicable Directives

•EMC Directives
• Low Voltage Directive

6-2 Concepts

EMC Directives
OMRON devices that comply with EC Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards (see the following note). Whether the products conform to the standards in the system used by the customer, however, must be checked by the customer.
EMC-related performance of the OMRON devices that comply with EC Direc­tives will vary depending on the configuration, wiring, and other conditions of the equipment or control panel on which the OMRON devices are installed.
xx
3-tier Communications with CX-Programmer 7
The customer must, therefore, perform the final check to confirm that devices and the overall machine conform to EMC standards.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN61131-2 EMI (Electromagnetic Interference): EN61000-6-4
(Radiated emission: 10-m regulations)
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75 to 1,500 VDC meet the required safety standards for the PC (EN61131-2).

6-3 Conformance to EC Directives

The CPM2C-S PCs comply with EC Directives. To ensure that the machine or device in which the CPM2C-S PC is used complies with EC Directives, the PC must be installed as follows:
1,2,3... 1. The CPM2C-S PC must be installed within a control panel.
2. Reinforced insulation or double insulation must be used for the DC power supplies used for the communications and I/O power supplies.
3. CPM2C-S PCs complying with EC Directives also conform to the Common Emission Standard (EN61000-6-4). Radiated emission characteristics (10­m regulations) may vary depending on the configuration of the control pan­el used, other devices connected to the control panel, wiring, and other conditions. You must therefore confirm that the overall machine or equip­ment complies with EC Directives.

1-1 CPM2C-S Features and Functions

1-1-1 CPM2C-S Features

The CPM2C-S PCs are compact CPM2C PCs that have been equipped with the functions of a CompoBus/S Master. The CPM2C-S incorporates a variety of special features just like the CPM2C, including synchronized pulse control, interrupt inputs, pulse outputs, and a clock function.
• The standard CompoBus/S interface increases the PC’s I/O capacity, reduces wiring, and saves space.
CompoBus/S Slaves
• The CPM2C-S is a compact Unit, so it can be incorporated into almost any machine. Furthermore, the CPM2C-S CPU Unit can be mounted in any direction.
• The CPM2C-S100C-DRT and CPM2C-S110C-DRT are also equipped with DeviceNet Slave functions to provide distributed control through a DeviceNet connection with a host PC.
• The CPM2C-S itself can handle a wide range of machine control applica­tions. In addition, the CPM2C-S is capable of communications with devices such as personal computers and OMRON Programmable Termi­nals so it is ideal to use to expand or upgrade existing systems.

• The CPM2C-S CPU Unit has a total of 10 I/O points: 6 inputs and 4 tran­sistor outputs. Up to 3 CPM2C-series Expansion I/O Units can be con­nected for a maximum I/O capacity of 106 I/O points with three 32-point Expansion I/O Units. It is possible to connect up to 362 I/O points by add­ing Slaves through the CompoBus/S system.
• The communications port can be used simultaneously as two ports: Peripheral and RS-232C. The peripheral port supports Programming Devices, Host Link, and no-protocol communications. The RS-232C port
2
CPM2C-S Features and Functions Section 1-1
supports Host Link, no-protocol (serial), 1:1 Link, and 1:1 NT Link com­munications.
• Connect up to 3 Expansion Units such as CPM2C-series Analog I/O Units, Temperature Sensor Units, or CompoBus/S I/O Link Units for Com­poBus/S Slave functions.
CompoBus/S Master Functions
Example System Configuration

CompoBus/S Slaves
When the CPM2C-S is used as a DeviceNet Slave, an I/O Link of up to 1,024 points (512 inputs and 512 outputs) can be created with the Master. The input and output areas used in the I/O Link can be allocated independently and the data areas, starting addresses, and size of these Read/Write areas can be specified freely. (The Read/Write areas can be set in the PC Setup or using the DeviceNet Configurator.)
Explicit message communications can be initiated from the Master to read or write data in any data area in the CPM2C-S.

CPM2C-S Features and Functions Section 1-1
Basic Functions
CPU Unit Variations The CPM2C-S PCs are one-piece PCs with 10 I/O points (6 inputs and 4 out-
puts) in a built-in connector. There are 2 types of outputs available (sinking transistor outputs, and sourcing transistor outputs). All CPM2C-S PCs require a 24-VDC power supply.
Expansion I/O Units and CompoBus/S Slaves
CompoBus/S Slaves and up to 3 Expansion I/O Units can be connected to the CPU Unit to increase the PC’s I/O capacity to a maximum of 362 I/O points. There are 23 different Expansion I/O Units available, including Units with 32 I/O points, 24 I/O points, 20 I/O points, 10 I/O points, 8 input points, 8 output points, 16 inputs points, and 16 output points. The maximum I/O capacity of 106 I/O points is achieved by connecting three 32-point Expansion I/O Units to the CPU Unit.
The CompoBus/S Master functions allow I/O Slaves to be connected provid­ing an additional capacity of up to 256 I/O points (128 inputs and 128 out­puts.)
Share Programming Devices
Either a Programming Console or the CX-Programmer (version 2.1 or later) can be used to program and monitor the CPM2C-S. Programs created on the SYSMAC-CPT or SYSMAC Support Software can also be used.
Built-in Motor Control Capability
Synchronized Pulse Control
Synchronized pulse control provides an easy way to synchronize the opera­tion of a peripheral piece of equipment with the main equipment. The output pulse frequency can be controlled as some multiple of the input pulse fre­quency, allowing the speed of a peripheral piece of equipment (such as a sup­ply conveyor) to be synchronized with the speed of the main piece of equipment.
CPM2C-S
High-speed Counters and Interrupts
Encoder
Pulses are output as a fixed multiple of the input frequency.
Motor driver
Motor
The CPM2C-S has a two kinds of high-speed counter inputs. The high-speed counter input has a response frequency of 20 kHz/5 kHz and the interrupt inputs (in counter mode) have a response frequency of 2 kHz.
• The single high-speed counter can be used in any one of the four input modes: differential phase mode (5 kHz), pulse plus direction input mode (20 kHz), up/down pulse mode (20 kHz), or increment mode (20 kHz). Interrupts can be triggered when the count matches a set value or falls within a specified range. One high-speed counter can be used.
• The interrupt inputs (counter mode) can be used for incrementing counters or decrementing counters (2 kHz) and trigger an interrupt (exe­cuting the interrupt program) when the count matches the target value. Two interrupt inputs can be used.

CPM2C-S Features and Functions Section 1-1
Easy Position Control with Pulse Outputs
CPM2C-S PCs have two outputs that can produce 10 Hz to 10 kHz pulses (single-phase outputs).
• When used as single-phase pulse outputs, there can be two outputs with a frequency range of 10 Hz to 10 kHz with a fixed duty ratio or 0.1 to
999.9 Hz with a variable duty ratio (0 to 100% duty ratio).
• When used as pulse plus direction or up/down pulse outputs, there can be just one output with a frequency range of 10 Hz to 10 kHz.
High-speed Input Capabilities for Machine Control
High-speed Interrupt Input Function
Quick-response Input Function
Stabilizing Input Filter Function
The CPU Units have 2 inputs that can be used as interrupt inputs. These inputs are shared with quick-response inputs and interrupt inputs in counter mode and have a minimum input signal width of 50 µs and response time of
0.3 ms. When an interrupt input goes ON, the main program is stopped and the interrupt program is executed.
The CPU Units have 2 inputs that can be used as quick-response inputs to reliably read inputs with a signal width as short as 50 µs regardless of the cycle time. These inputs are shared with interrupt inputs and interrupt inputs in counter mode.
The input time constant for all inputs can be set to 1 ms, 2 ms, 3 ms, 5 ms, 10 ms, 20 ms, 40 ms, or 80 ms. The effects of chattering and external noise can be reduced by increasing the input time constant.
Analog I/O Supported by Expansion Units and CompoBus/S Master Functions
Analog I/O Units Up to 3 optional Analog I/O Units can be connected to the CPM2C-S. For
each Analog I/O Unit mounted to the Unit, 2 analog input points and 1 analog output point are available. By mounting 3 Analog I/O Units, a maximum of 6 analog input points and 3 analog output points can be made available. (By using a combination of the PID(––) instruction and PWM(––) instruction, time proportional control is possible.)
• The ranges supported for analog input signals are 0 to 5 V, 0 to 10 V, –10 to 10 V, 0 to 20 mA, and 4 to 20 mA, and the resolution is 1/6000 (full scale). The averaging function and power interruption detection function can be used.
• The ranges supported for analog output signals are 1 to 5 V, 0 to 10 V, –10 to 10 V, 0 to 20 mA, and 4 to 20 mA, and the resolution is 1/6000 (full scale).
Analog I/O Terminals Up to 8 analog inputs and 8 analog outputs can be connected through a Com-
poBus/S Analog I/O Terminal.
Temperature Sensor Units Up to 3 optional Temperature Sensor Units can be mounted to the CPM2C-S.
There are 2 models of Temperature Sensor Unit: One for input from a thermo­couple sensor and one for input from a platinum resistance thermometer sen­sor. There are 2 input points on each Temperature Sensor Unit.
• Thermocouple inputs (and measurement ranges): K (–200 to 1,300°C), K (0.0 to 500.0°C), J (-100 to 850°C), and J (0.0 to 400.0°C).
• Platinum resistance thermometer inputs (and measurement ranges): Pt100 (–200.0 to 650.0°C), JPt100 (–200.0 to 650.0°C).

Other Functions
Interval Timer Interrupts The interval timer can be set between 0.5 and 319,968 ms and can be set to
generate just one interrupt (one-shot mode) or periodic interrupts (scheduled interrupt mode).
Calendar/Clock The clock (accuracy within 1 minute/month) can be read from the program to
show the current year, month, day, day of the week, and time. The clock can be set from a Programming Device (such as a Programming Console) or the time can be adjusted by rounding up or down to the nearest minute.
Long-term Timer TIML(––) is a long-term timer that accommodates set values up to 99,990
seconds (27 hours, 46 minutes, 30 seconds). When combined with the SEC­ONDS TO HOURS conversion instruction (HMS(––)), the long-term timer pro­vides an easy way to control equipment scheduling.
Expansion Memory Unit The CPM1-EMU01-V1 Expansion Memory Unit is a program loader for small-
size or micro PCs. Using the CPM1-EMU01-V1, simple on-site transfer of user programs and data memory (DM 6144 to DM 6655) is possible with PCs.

1-2-2 CompoBus/S Interface

The standard built-in CompoBus/S interface increases the PC’s I/O capacity, reduces wiring, and saves space. Up to 32 CompoBus/S Slaves can be con­nected to create a Remote I/O Link with up to 256 I/O points. It is easy to build an efficient, long-range distributed system with less wiring by connecting CompoBus/S I/O Terminals, Analog Terminals, Sensor Terminals, and Bit Chain Terminals.

I/O Memory The program reads and writes data in this memory area during execution.
Part of the I/O memory contains the bits that reflect the status of the PC’s inputs and outputs. Parts of the I/O memory are cleared when the power is turned ON and other parts are retained.
Note Refer to SECTION 4 Memory Areas for more details on I/O memory.
Program This is the program written by the user. The CPM2C-S executes the program
cyclically. (Refer to 1-3-5 Cyclic Operation and Interrupts for details.)
The program can be divided broadly into two parts: the “main program” that is executed cyclically and the “interrupt programs” that are executed only when the corresponding interrupt is generated.
PC Setup The PC Setup contains various startup and operating parameters. The PC
Setup parameters can be changed from a Programming Device only; they cannot be changed from the program.
Some parameters are accessed only when PC’s power supply is turned ON and others are accessed regularly while the power is ON. It will be necessary to turn the power OFF and then ON again to enable a new setting if the parameter is accessed only when the power is turned ON.
Note Refer to 4-6 PC Setup for details on the PC Setup.
Communications Switches
The Communications Switches determine whether the peripheral port and RS-232C port connected through the communications port operate with the
17
CPM2C-S Structure and Operation Section 1-3
standard communications settings or the communications settings in the PC Setup.

1-3-2 Operating Modes

CPM2C-S CPU Units have 3 operating modes: PROGRAM, MONITOR, and RUN.
PROGRAM Mode The program cannot be executed in PROGRAM mode. This mode is used to
perform the following operations in preparation for program execution.
• Changing initial/operating parameters such as those in the PC Setup
• Writing, transferring, or checking the program
• Checking wiring by force-setting and force-resetting I/O bits
!Caution The PC continues to refresh I/O bits even if the PC is in PROGRAM mode, so
devices connected to output points may operate unexpectedly if the corre­sponding output bit is turned ON by transferring I/O memory or force-setting output bits from a Programming Device. When output bits are allocated to the DeviceNet I/O Link Write Area, data writ­ten to the output bits through DeviceNet is effective immediately and the out­put bits may go ON even if the PC is in PROGRAM mode. Do not change the status of output bits from a Programming Device or DeviceNet unless it is safe to do so.
MONITOR Mode The program is executed in MONITOR mode and the following operations can
be performed from a Programming Device. In general, MONITOR mode is used to debug the program, test operation, and make adjustments.
• Online editing
• Monitoring I/O memory during operation
• Force-setting/force-resetting I/O bits, changing set values, and changing present values during operation
RUN Mode The program is executed at normal speed in RUN mode. Operations such as
online editing, force-setting/force-resetting I/O bits, and changing set values/ present values cannot be performed in RUN mode, but the status of I/O bits can be monitored.

1-3-3 Operating Mode at Startup

The operating mode of the CPM2C-S when the power is turned ON depends upon the setting of pin 4 on the DIP switch on the front of the CPM2C-S, the PC Setup settings in DM 6600, and the Programming Console’s mode switch setting if a Programming Console is connected.

4 and the Programming Device connected to the communications port (pe­ripheral port).
Programming Device Pin 4 OFF Pin 4 ON
None PROGRAM mode RUN mode
Programming Console Operating mode set on the Programming Console’s
mode switch
Other device PROGRAM mode
The default setting for bits 08 to 15 of DM 6600 is 00. If this default setting is used and pin 4 is OFF, the CPM2C-S will automatically start operating in RUN mode when the power is turned ON.
2. If pin 4 is OFF and only an RS-232C cable is connected to the communi­cations port (i.e., there is no peripheral port connection), the CPM2C-S will automatically start operating in RUN mode when the power is turned ON.
Example Cable Connections: CS1W-CN118 and XW2Z-200S/500S CS1W-CN118 and XW2Z-200S-V/500S-V CPM2C-CN111 and XW2Z-200S/500S (no peripheral port connection) CPM2C-CN111 and XW2Z-200S-V/500S-V (no peripheral port connec­tion)

1-3-4 PC Operation at Startup

Time Required for Initialization
Power OFF Operation Minimum Power Supply Voltage
The time required for startup initialization depends on several factors, such as the operating conditions (including power supply voltage, system configura­tion, and ambient temperature) and the program contents.
The PC will stop and all outputs will be turned OFF if the power supply voltage falls below 85% of the rated value.
Momentary Power Interruption
A power interruption will not be detected and CPU Unit operation will continue if the power interruption lasts less than 2 ms.
A power interruption may or may not be detected for power interruptions somewhat longer than 2 ms.
When a power interruption is detected, the CPU Unit will stop operating and all outputs will be turned OFF.
Automatic Reset
Operation will restart automatically when the power supply voltage is restored to more than 85% of the rated voltage.
Timing Chart of Power OFF Operation
The power interruption detection time is the time required for a power interrup­tion to be detected after the power supply voltage drops below 85% of the rated value.

Note If the power supply voltage fluctuates around 85% of the PC’s rated voltage,
PC operation may stop and restart repeatedly. When repeated stopping and starting will cause problems with the controlled system, set up a protective cir­cuit such as a circuit that shuts OFF the power supply to sensitive equipment until the power supply voltage returns to the rated value.

21
CPM2C-S Structure and Operation Section 1-3
The cycle time will vary slightly depending on the processing being performed in each cycle, so the calculated cycle time will not always match the actual cycle time.
Program Execution in Cyclic Operation
The following diagram shows the cyclic operation of the CPM2C-S when the program is being executed normally.
Normally, the results of program execution are transferred to I/O memory just after program execution (during I/O refreshing), but IORF(97) can be used to refresh a specified range of I/O words during program execution. The speci­fied range of I/O words will be refreshed when IORF(97) is executed.
The cycle time is the sum of the time required for program execution, I/O refreshing, and communications port servicing.
A minimum cycle time (1 to 9,999 ms) can be set in the PC Setup (DM 6619). When a minimum cycle time has been set, CPU operation is paused after pro­gram execution until the minimum cycle time is reached. CPU operation will not be paused if the actual cycle time is longer than the minimum cycle time set in DM 6619.
Note A fatal error will occur and PC operation will stop if a maximum cycle time has
been set in the PC Setup (DM 6618) and the actual cycle time exceeds that setting.
The default settings for RS-232C and peripheral port servicing are 5% each of the cycle time, but these settings can be changed (between 0% and 99%) in the PC Setup. The RS-232C port’s setting is in DM 6616 and the peripheral port’s setting is in DM 6617.
Refer to SECTION 7 Cycle Time and I/O Response Time for more details and precautions on the cycle time.

CPM2C-S Structure and Operation Section 1-3
Interrupt Program Execution
When an interrupt is generated during execution of the main program, main program execution is interrupted immediately and the interrupt program is executed. The following diagram shows the cyclic operation of the CPM2C-S when an interrupt program is executed.
Normally, the results of interrupt program execution are transferred to I/O memory just after program execution (during I/O refreshing), but IORF(97) can be used to refresh a specified range of I/O words during execution of the interrupt program. The specified range of I/O words will be refreshed when IORF(97) is executed.
The normal cycle time is extended by the time required for execution of the interrupt program.
Refer to SECTION 7 Cycle Time and I/O Response Time for more details and precautions on the cycle time.

!Caution Although IORF(97) can be used in interrupt subroutines, you must be careful
of the interval between IORF(97) executions. If IORF(97) is executed too fre­quently, a fatal system error may occur (FALS 9F), stopping operation. The interval between executions of IORF(97) should be at least 1.3 ms + total exe­cution time of the interrupt subroutine.
23
CPM2C-S Structure and Operation Section 1-3
Immediate Refreshing IORF(97) can be executed in the program to refresh a specified range of I/O
words. The specified I/O words will be refreshed when IORF(97) is executed.
IORF(97) can be used to refresh I/O from the main program or the interrupt program.
When IORF(97) is used, the cycle time is extended by the time required to refresh the specified I/O words.

Design Precautions Section 3-1

3-1 Design Precautions

Observe the following precautions when designing a system incorporating a CPM2C-S PC.

3-1-1 Power Supply Wiring

Separate the power supply wiring from the control system, CPM2C-S system, and DC I/O system wiring. Separate the control circuits that supply power to the main Unit from the main circuits using dedicated circuit protectors and fuses.

3-1-2 Power Supply Voltage

!Caution Use the power supply voltages indicated in SECTION 2 Unit Components and
Specifications. Failure to adhere to the specifications may result in fire.
If the power supply voltage falls below 85% of the rated voltage, the CPM2C­S will stop and all outputs will be turned OFF. If low voltage affects the equip­ment, etc., provide a protection circuit which shuts OFF the output until the supply voltage returns to the rated value. In places where power supply conditions are poor, take steps to ensure that power is supplied at the rated voltage. Be sure to adhere to safety precau­tions, such as providing breakers to prevent short circuits in external wiring. When conducting any of the following operations, turn OFF the power to the PC. Electrocution, product damage and malfunction may result.
• Connecting or disconnecting Expansion I/O Units, Expansion Units, and CPU Units.
• Assembling Units.
• Connecting cables and wiring.
• Connecting or disconnecting connectors.
• Replacing the battery.

3-1-3 Interlock and Limit Circuits

!WARNING Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits (i.e., not in the Pro­grammable Controller) to ensure safety in the system if an abnormality occurs due to malfunction of the PC or another external factor affecting the PC oper­ation. Not providing proper safety measures may result in serious accidents.
The following diagram shows an example of an interlock circuit.

strands of wire get inside the Unit. After completing wiring be sure to remove the label to avoid overheating.
Protective label
I/O Line Noise Do not run CPM2C-S I/O lines in the same duct or conduit as power lines.
!Caution If flat cables are connected for more than one CompoBus/S network, interfer-
ence between the flat cables can cause unstable operation. If you are using more than one network, be sure the flat cables are separated by at least 5mm.
Hanging Ducts
Leave at least 300 mm between the power cables and the I/O or control wir­ing, as shown in the following diagram.

1,2,3... 1. Align the power supply connector with the socket on the bottom of the
CPM2C-S and insert the connector.
Red lead: +24 VDC
Black lead: 0 VDC
2. To remove the power supply connector, grasp the power supply connector (not the wires), release the lock tab on the connector, and remove the con­nector.
Note 1. The CPM2C-PA201 is the recommended Power Supply Unit, but a gener-
al-purpose power supply such as a S82J-series or S82K-series Power Supply can also be used. When using other power supplies, be sure to use a DC power supply with sufficient capacity and low ripple.
2. Do not perform a voltage withstand test on the DC power supply terminals on the CPU Unit. The test might damage the PC’s internal components.
3. When the equipment must conform to the EC Directives (Low-voltage Di­rectives), use a power supply with double insulation or reinforced insula­tion.

3-4-3 Using the AC Power Supply Unit

Crimp Terminals Use round crimp terminals for wiring AC power supply to the AC Power Sup-
ply Unit (CPM2C-PA201). Use either crimp terminals or solid wires for wiring to the ground terminal or the service power supply terminals. Do not connect bare stranded wires directly to terminals.
• Use M3.5 terminal screws.
• Tighten the terminal screws securely to a torque of 0.74 to 0.9 N·m.
Use round terminals of the dimensions shown below.
Round Terminal
6.2 mm max.
Recommended wire diameter when using solid wires: 0.6 to 1.6 mm (AWG 22 to 14).
Grounding To prevent electric shock resulting from malfunction due to factors such as
noise, connect to a ground of 100 or less. When grounding, use a wire at
least 1.25 mm
2
thick.
62
Wiring and Connections Section 3-4
!WARNING Connect the ground terminal of the Power Supply Unit to a ground of 100 or
less when installing the Unit. Not connecting to a ground of 100 or less may result in electric shock.
Ground of 100 or less
Power Supply Wiring • To prevent voltage drops caused by startup currents and inrush currents
from other devices, wire the power supply circuits of the CPM2C-S sepa­rately from power line circuits.
• When using several CPM2C-S PCs together, it is recommended that cir­cuits are wired separately in order to prevent circuit-breaker malfunctions and voltage drops due to inrush current.
• Twist power supply lines to prevent noise from the power supply lines. Noise can further be prevented by wiring via a 1:1 isolation transformer.
• Use wires at least 1.25 mm to keep the current within the allowable level.

thick in order to allow for voltage drops and
100 to 240 VAC
!WARNING Tighten the screws on the terminal block of the AC Power Supply Unit to a
torque of 0.74 to 0.9 N·m. Loose screws may result in burning or malfunction.
The 24-VDC service power supply terminals on the terminal block can be used for input power supply.
24 VDC Can be used for input power supply.
63
Wiring and Connections Section 3-4
Use the following to obtain the capacity of the service power supply that can be used.
Example: CPU Unit + 3 Expansion I/O Units
Power consumption = 4 W (the CPU Unit’s power consumption) + 1 W (the Expansion I/O Unit’s power consumption) × 3 (No. of Expansion I/O Units) = 7 W Service power supply current = (14.4 W (CPM2C-PA201’s rated capacity) – 7 W (power consumption)) ÷ 24 (V) = 308 (mA)
!WARNING If the 24-VDC output (either the service power supply or the power supply to
the CPU Unit) is overloaded, or is short-circuited, the voltage will drop, and the output will turn OFF. Take external countermeasures to ensure the safety of the system in such an event. Failure to do so may result in a serious acci­dent.
!WARNING Do not connect a power supply to the service power supply terminals. If an AC
power supply is mistakenly connected to these terminals, the internal circuitry will be damaged.

Output Wiring Precautions Observe the following precautions to protect the PC’s internal components.
Output Short Protection
The output or internal circuitry might be damaged when the load connected to an output is short-circuited, so it is recommended to install a protective fuse in each output circuit.
Inductive Loads
When connecting an inductive load to an input, connect a surge protector or diode in parallel with the load.
74
Wiring and Connections Section 3-4
The surge protector’s components should have the following ratings:
Transistor Output (Sinking)

The diode should satisfy the following requirements:
Peak reverse-breakdown voltage must be at least 3 times the load voltage. Average rectified current must be 1 A.
