xviii
Application Precautions 5
!Caution Failure to abide by the following precautions could lead to faulty operation of
the PC or the system, or could damage the PC or PC Units. Always heed
these precautions.
• 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.
• Use the correct power supply voltage.
• 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.)
• For models with only the super-capacitor installed, the contents of the
READ/WRITE enable area of the DM area, HR area, AR area, and CNT
data area may be damaged if the power is turned OFF for a long time. To
prevent such damage, provide ladder program that will check AR 1314 in
order to ensure proper operation of the system.
• The life expectancy of the output relay varies considerably according to its
switching capacity and switching conditions. If the output relay is used
beyond its life expectancy, its contacts may become fused or burned.
• Install the Units properly so that they will not fall off.
• Be sure that all the mounting screws, terminal screws, and cable connector screws are tightened to the torque specified in the relevant manuals.
Incorrect tightening torque may result in malfunction.
• 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. If the power supply for the I/O circuits is turned ON with the input and
output connectors reversed, the fuse of output transistor may be blown.
• 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 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 AC power supply input to the AC
Power Supply Unit (CPM2C-PA201). For wiring the ground terminals or
power supply service terminals, use crimp terminals or solid wires. Do not
connect bare stranded wires directly to terminals. Connection of bare
stranded wires may result in burning.

Application Precautions 5
• Be sure to perform wiring in accordance with the CPM2C Operation Manual. Incorrect wiring may result in burning.
• Use specified connectors and wiring materials (connector models: C500CE241/C500-CE242/C500-CE243; terminal block models: AWG28-16
with stripped length of 7 mm; Power Supply Unit terminal block: AWG2214 with stripped length of 7 mm).
• 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.
• 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.
• 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

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.
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
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 PCs comply with EC Directives. To ensure that the machine or
device in which the CPM2C PC is used complies with EC Directives, the PC
must be installed as follows:
1,2,3... 1. The CPM2C 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. Basic insulation is provided between the commons of different polarities of
the output relay for the CPM2C-20@@R (model with 20 relay output
points).
When connecting devices that operate at voltages higher than 50 VAC and
those that operate on DC power supplies to adjoining relay output terminals, use different DC power supplies for output devices from those for input devices and the CPM2C power supply.
4. CPM2C PCs complying with EC Directives also conform to the Common
Emission Standard (EN61000-6-4). Radiated emission characteristics
(10-m 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.
(Radiated emission: 10-m regulations)

EC Directives 6
6-4 Relay Output Noise Reduction Methods
The CPM2C PCs conform to the Common Emission Standards (EN61000-6-
4) of the EMC Directives. However, the noise generated when the PC is
switched ON or OFF using the relay output may not satisfy these standards. In
such a case, a noise filter must be connected to the load side or other appropriate countermeasures must be provided external to the PC.
Countermeasures taken to satisfy the standards vary depending on the
devices on the load side, wiring, configuration of machines, etc. Following are
examples of countermeasures for reducing the generated noise.
Countermeasures
(Refer to EN61000-6-4 for more details.)
Countermeasures are not required if the frequency of load switching for the
whole system with the PC included is less than 5 times per minute.
Countermeasures are required if the frequency of load switching for the whole
system with the PC included is 5 times or more per minute.
Countermeasure Examples
When switching an inductive load, connect a surge protector, diodes, etc., in
parallel with the load or contact as shown below.

If the supply voltage is 24 to 48 V,
insert the surge protector in parallel
with the load. If the supply voltage is
100 to 200 V, insert the surge protector
between the contacts.
The capacitance of the capacitor must
be 1 to 0.5 µF per contact current of
1 A and resistance of the resistor must
be 0.5 to 1 Ω per contact voltage of 1 V.
These values, however, vary with the
load and the characteristics of the
relay. Decide these values from experiments, and take into consideration that
the capacitance suppresses spark discharge when the contacts are separated and the resistance limits the
current that flows into the load when
the circuit is closed again.
The dielectric strength of the capacitor
must be 200 to 300 V. If the circuit is an
AC circuit, use a capacitor with no
polarity.

1-1 CPM2C Features and Functions
1-1-1 CPM2C Features
The CPM2C PCs incorporate a variety of features in a compact Unit, including
synchronized pulse control, interrupt inputs, pulse outputs, and a clock function. The CPM2C CPU Unit is a stand-alone Unit that can handle a broad
range of machine control applications and it is small enough to be incorporated as the control unit in almost any free-standing machine.
The full complement of communications functions provide communications
with personal computers, other OMRON PCs, and OMRON Programmable
Terminals. These communications capabilities allow the user to design a lowcost distributed production 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 supports Host Link, no-protocol
serial),1:1 Link,and 1:1 NT Link communications.
CPU Units with 10 I/O points (relay or transistor
outputs) or with 20 or 32 I/O points (transistor
outputs only) are available. Expansion I/O Units
can be connected to increase capacity to 192 I/O
points.
Basic Functions
CPU Unit Variations The CPM2C PCs are one-piece PCs with 10, 20, or 32 I/O points in I/O termi-
nals or a built-in connector. There are 3 types of outputs available (relay outputs, sinking transistor outputs, and sourcing transistor outputs). All CPM2C
PCs require a 24-VDC power supply.
Expansion I/O Units Up to 5 Expansion I/O Units can be connected to the CPU Unit to increase the
PC’s I/O capacity to a maximum of 192 I/O points. There are 23 different
Expansion I/O Units available, including Units with 10 I/O points, 24 I/O points,
32 I/O points, 8 input points, 8 output points, 16 inputs points, and 16 output
points. The maximum I/O capacity of 192 I/O points is achieved by connecting
five 32-point Expansion I/O Units to a CPU Unit with 32 built-in I/O points.
Share Programming
Devices
Programming and monitoring for the CPM2C can be performed with CX-Programmer version 2.1 or higher or with a Programming Console. Programming
is also possible with the SYSMAC-CPT or SYSMAC Support Software.

Built-in Motor Control Capability
Synchronized Pulse
Control
(Transistor Outputs Only)
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.

The CPM2C has a two kinds of high-speed counter inputs. The high-speed
counter input has a response frequency of 5 or 20 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.
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. Four interrupt inputs
can be used in the 20- and 32-point CPU Units and two interrupt inputs can be
used in the 10-point CPU Units.
CPM2C PCs with transistor outputs 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.

Function
The 20-point and 32-point CPU Units have 4 inputs that can be used as interrupt inputs and the 10-point 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
and response time of 0.3 ms. When an interrupt input goes ON, the main program is stopped and the interrupt program is executed.
Regardless of the cycle time, the 20-point and 32-point CPU Units have 4
inputs that can be used as quick-response inputs and the 10-point CPU Units
have 2 inputs that can be used as quick-response inputs. These inputs are
shared with interrupt inputs and interrupt inputs in counter mode; they can
reliably read input signals with a signal width as short as 50
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.

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 In CPU Units with a built-in 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(

Analog I/O Supported Up to 4 Analog I/O Units can be mounted to the CPM2C. For each Analog I/O
Unit mounted to the Unit, 2 analog input points and 1 analog output point are
available. By mounting 3 (see note) Analog I/O Units, a maximum of 8 analog
input points and 4 analog output points can be made available. (By using a
combination of the PID(
tional 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 average processing 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).
Note When using the CPM2C-PA201, there is a limit to the number of CPM2C-
MAD11 Units that can be connected. This limit ensures that the power consumption of the CPU Unit, Expansion Units, and Expansion I/O Units does not
exceed the total power capacity of the service power supply from the Power
Supply Unit (24 V x 600 mA = 14.4 W).

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 3 Memory Areas in the Programming Manual (W353) for
more details on I/O memory.
Program This is the program written by the user. The CPM2C 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 Section 1 PC Setup in the Programming Manual (W353) for more
details.
Communications Switch The Communications Switch controls the communications settings for the
peripheral port and the RS-232C port.
14
Structure and Operation Section 1-3
1-3-2 Operating Modes
CPM2C 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 on the CPU Unit, Expansion Units, or
Expansion I/O Units may operate unexpectedly if the corresponding output bit
is turned ON by changing the contents of I/O memory.
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 when the power is turned ON depends
upon the PC Setup settings and the Programming Console’s mode switch setting if a Programming Console is connected.

the CPU Unit will start in RUN mode as soon as power is turned ON. Be
sure that adequate precautions are taken to ensure safety.

1-7 Changes in
1-3-4 PC Operation at Startup
Time Required for
Initialization
Power OFF Operation
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.
Minimum Power Supply Voltage
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.

Stopped
CPU Unit operation may

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.
17
Structure and Operation Section 1-3
1-3-5 Cyclic Operation and Interrupts
Basic CPU Operation Initialization processing is performed when the power is turned ON. If there
are no initialization errors, the overseeing processes, program execution, I/O
refreshing, and communications port servicing are performed repeatedly
(cyclically).
• Check hardware.

• Check memory.
• Read data from flash memory (program,

• Wait for minimum cycle time if a minimum
cycle time has been set in the PC Setup
(DM 6619).
• Calculate cycle time.
• Read input data from input bits.
• Write output data to output bits.
• Perform RS-232C port communications
processing. (Can be changed in DM 6616.)
18
Peripheral port
servicing
• Perform peripheral port communications
processing. (Can be changed in DM 6617.)
The cycle time can be read from a Programming Device.
AR 14 contains the maximum cycle time and AR 15 contains the present
cycle time in multiples of 0.1 ms.
Structure and Operation Section 1-3
C
t
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 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 PC Operations and Processing Time in the Programming
Manual (W353) for more details and precautions on the cycle time.

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
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 PC Operations and Processing Time in the Programming
Manual (W353) 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.
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.

OFF Use the settings in the PC Setup (DM 6645 to DM 6649). If a Pro-
gramming Console is connected to the peripheral port, however,
operation will be in the Programming Console mode.
ON Use the standard settings (1 start bit, 7 data bits, 2 stop bits, even
parity, and 9,600 bps baud rate.) If a Programming Console is connected to the peripheral port, however, operation will be in the Programming Console mode.
9. Customize Switch
The Customize Switch can be used to turn ON and OFF AR 0712 in CPU
Unit memory. AR 0712 will turn ON and OFF according to the status of
SW2 regardless of the operating mode of the CPM2C.
SW2 Operation
OFF Turns OFF AR 0712.
ON Turns ON AR 0712.
Note SW2 functions as the communications switch for some Units. Refer
to
1-7 Changes in SW2 for details.
10. Battery
This battery backs up memory in CPU Units with an internal clock. The bat-
tery is connected when the Unit is shipped.
Note A battery is not included in CPU Units without an internal clock, but
a CPM2C-BAT01 Battery can be purchased separately and connected to backup memory.
11. Low Battery Detection Switch

Note Input indicators will reflect the status of the corresponding inputs
even when the PC is stopped, but the corresponding input bits will
not be refreshed.
4. Output Indicators
The output indicators are lit when the corresponding output terminal is ON.
5. Expansion I/O Connector (Input)
Connects the Expansion I/O Unit to the CPU Unit or the previous Expansion Unit or Expansion I/O Unit.
Note The indicators are lit during I/O refreshing. The status of an output
indicator will also reflect the status of the corresponding output when
the output is being used as a pulse output.
6. Expansion I/O Connector (Output)
Connects the Expansion I/O Unit to the next Expansion I/O Unit or Expansion Unit, if necessary. Up to 5 Expansion I/O Units and Expansion Units
can be connected to a CPU Unit. Only 10 words, however, can be allocated
for input and output.
A cover for the expansion I/O connector is not included with the Expansion
I/O Unit. Use the cover included with the CPU Unit to cover the unused expansion I/O connector on the last Expansion I/O Unit or Expansion Unit in
the PC.
7. Locking Lever
Used for securing Expansion I/O Units.
