accidents.
• Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.
• The PLC 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.
xviii
Operating Environment Precautions 4
• The PLC 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.
!WARNING When the 24-VDC output (service power supply to the PLC) is overloaded or
short-circuited, the voltage may drop and result in the outputs being turned
OFF. As a countermeasure for such problems, external safety measures must
be provided to ensure safety in the system.
!Caution When wiring crossovers between terminals, the total current for both terminals
will flow in the line. Check the current capacities of all wires before wiring
crossovers.
!Caution Tighten the screws on the terminal block of the AC Power Supply Unit to the
torque specified in the operation manual. The loose screws may result in
burning or malfunction.
!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.

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.
• Always use the power supply voltage specified in this manual. An incorrect voltage may result in malfunction or burning.
• Take appropriate measures to ensure that the specified power with the
rated voltage and frequency is supplied. Be particularly careful in places
where the power supply is unstable. An incorrect power supply may result
in malfunction.
• Install external breakers and take other safety measures against short-circuiting in external wiring. Insufficient safety measures against short-circuiting may result in burning.
• Do not apply voltages to input sections in excess of the rated input voltage. Excess voltages may result in burning.
• Do not apply voltages or connect loads in excess of the maximum switching capacity to output sections. Excess voltage or loads may result in
burning.
• 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.
• Wiring correctly, as indicated in this manual.
• Do not attempt to disassemble, repair, or modify any Units.

EC Directives 6
• Remove the labels after the completion of wiring to ensure proper heat
dissipation. Leaving the label attached may result in malfunction.
• Do not pull on cables and cords and do not bend them past their natural
bending radius.
• Do not place any heavy objects on cables or cords.
• Mount the Unit only after checking the terminal block completely.
• Be sure that the terminal blocks, Memory Units, expansion cables, and
other items with locking devices are properly locked into place. Improper
locking may result in malfunction.
• Check the user program for proper execution before actually running it on
the Unit. Not checking the program may result in an unexpected operation.
• Use crimp terminals for wiring. Do not connect bare stranded wires
directly to terminals. Connection of bare stranded wires may result in
burning.
• Double-check all the wiring before turning on the power supply. Incorrect
wiring 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 PLC (including the setting of the
startup operating mode).
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• Touch a grounded metal object to discharge static electricity from your
body before touching any Unit.
6 EC Directives
CS/CJ-series Units conform to EC Directives. For the system to conform to
EC Directives, however, the following precautions must be adhered to.
• CS/CJ-series Units must be installed within control panels.
• Use reinforced insulation or double insulation for the DC power supplies
used for the I/O power supplies.
• CS/CJ-series Units that meet EC Directives also meet the Common Emission Standard (EN61000-6-4). The measure necessary to ensure that
standards, such as the radiated emission standard (10 m), are met, however, will vary depending on the overall configuration of the control panel,
the other devices connected to the control panel, and wiring. You must
therefore confirm that EC Directives are met for the overall machine or
device.

EMC and Low Voltage Directives
EMC Directive
In order that OMRON products can be used with any machinery and in combination with other manufacturer’s equipment, the products themselves are
designed to comply with EMC standards (see note 1.), so that the assembled
machinery or device can then also easily comply with EMC standards.
Even if machinery and equipment complies with EMC standards before
assembly, this compliance may change depending on the device, the configuration of the control panel, and wiring, so OMRON cannot guarantee that particular system complies with the directive. You must therefore confirm that
EMC Directives are met for the overall machine or device.

8 Precautions for the C200H-AD003, C200H-DA003/004, and
C200H-MAD01
Note the following important differences between the CS-series Analog I/O
Units and the C200H Analog I/O Units.
Current Input Wiring
The CS1W-AD041-V1/081-V1 Analog Input Units and the CS1W-MAD44
Analog I/O Unit do not have a current input terminal. To switch analog conversion input from voltage input to current input, the voltage/current switch must
be turned ON. Refer to 2-3-4 or 6-3-4 Voltage/Current Switch.
Mean Value Processing
The default setting for mean value processing in the CS1W-AD041-V1/081-V1
Analog Input Units and the CS1W-MAD44 Analog I/O Unit is mean value processing with 2 buffers. By changing the setting in data memory, no mean processing can be selected. Refer to 2-6-3 or 6-6-2 Mean Value Processing.
Operation Mode Switch
To change from normal mode to adjustment mode, or vice versa, with the
C200H-AD003, C200H-DA003/004, or C200H-MAD01 Analog I/O Units, it is

necessary to create an I/O table. With the CS-series Analog I/O Units, the
operation mode switch can be used to make this change. Therefore the I/O
table is no longer necessary. Refer to 2-7-1, 4-7-1 or 6-9-1 Adjustment Mode
Operational Flow.
Error Flags
The C200H-AD003, C200H-DA003/004, and C200H-MAD01 use error codes,
whereas the CS-series Analog I/O Units use error flags. When the ERC indicator is lit due to a setting error in the DM area or an operating error, a bit flag
will be stored in the CIO Area. Refer to 2-8-2 Alarms Occurring at the Analog
Input Unit, 4-8-2 Alarms Occurring at the Analog Output Unit,
Alarms Occurring at the Analog I/O Unit.

It is now possible to set A/D and D/A conversion times and resolution. The
settings are made in D(m+18) in the DM Area allocated for Special I/O Units.
Either a conversion time of 1 ms and a resolution of 4,000 or a conversion
time of 250
set. For details, refer to 5-6-2 Conversion Time/Resolution Setting (CJ1W-
DA08V/08C Only) and 7-6-2 Conversion Time and Resolution Setting.
With the scaling function, values within a range of ±32,000 can be set in the
DM Area words allocated for Special I/O Units, in user-specified units, as
upper and lower limits. A/D and D/A conversion are then executed with these
upper and lower limits taken as full scale. The scaling function is only enabled
when a conversion time of 1 ms and a resolution of 4,000 are set. For details,
refer to 5-6-5 Output Scaling Function (CJ1W-DA08V/08C Only), 7-6-5 Input
Scaling Function, and 7-7-4 Output Scaling Function.
When “1 to 5 V, 4 to 20 mA” is set for the I/O signal range, either the “1 to 5 V”
or “4 to 20 mA” range can then be selected by means of the D(m+35) setting.
Adjusting the factory-set voltage and current can improve the accuracy of current output specifications in comparison to earlier models. For details, refer to
Voltage/Current Range Setting in 7-6-1 Input Settings and Conversion Values
and 7-7-1 Output Settings and Conversions.
With earlier models, the operation mode (normal mode and adjustment mode)
was changed by means of a DIP switch setting on the rear panel of the Unit.
(With CJ1W/CS1W-AD041-V1/08-V1 Units, the operation mode can be
changed by means of either a rear-panel switch or a DM Area setting.)
With the CJ1W-DA08V/DA08C/MAD42, it is possible only by means of a setting in D(m+18) in the Special I/O Unit DM Area. For details, refer to 5-6-2
Conversion Time/Resolution Setting (CJ1W-DA08V/08C Only), 7-6-2 Conversion Time and Resolution Setting, and 7-7-2 Conversion Time and Resolution

Scaling Function With CS1W-AD161 Analog Input Units, CJ1W-DA08V/08C Analog Output
Units (See note 1.), and CJ1W-MAD42 Analog I/O Units, input analog values
and output analog set values can be automatically converted into user-specified units. This scaling function eliminates the previous need to provide programs (e.g., scaling using the SCL instruction) for numeric conversion to
different units.
When upper and lower limits have been preset in 16-bit binary data in the
CPU Unit’s DM Area, within a decimal range of
−32,000 to +32,000, input
analog values and output analog set values can be automatically converted
5

into user-specified units. (See note 2.) When input values are negative, they
are set using two’s complement.
Note 1. Only output scaling is supported by CJ1W-DA08V/08C Analog Output
Units.
2. This is possible only for a conversion time of 1 ms and a resolution of
4,000. The scaling function is not enabled for a conversion time of 250
(500 µs for the CJ1W-MAD42) and a resolution of 8,000.
