Unit Versions of CS/CJ-series Controller Link Units
Unit Versions
A “unit version” has been introduced to manage CS/CJ-series Controller Link Units according to differ-
ences in functionality accompanying upgrades.
Unit Version Notation on Products
The unit version code is provided on the nameplate of the CS/CJ-series Controller Link Units for which
unit versions are being managed. This system applies to Controller Link Units with unit version 1.2 or
later.
Confirming Unit Versions with Support Software
CX-Programmer version 5.0 or higher can be used to confirm the unit version in the Unit Manufacturing
Information.
1,2,3... 1. 1. In the I/O Table Window, right-click on the Controller Link Unit, and then
select Unit Manufacturing Information.
2. The following Unit Manufacturing Information Dialog Box will be displayed.
Example: In this Unit Manufacturing Information Dialog Box, unit version
1.2 is displayed. Use this dialog box to confirm the unit version of the Con-
troller Link Unit that is connected online.

Using the Unit Version Labels
Unit version labels are provided with the product. These labels can be attached to the front of previous
Controller Link Units to differentiate between Controller Link Units of different unit versions.
Unit Version Notation
The unit versions are indicated in this manual as follows:
Function Support by Unit Version
Note Use the CX-Net in CX-Programmer version 5.0 or later to set a data link area
in which the number of send and receive words exceeds 12,000 words, or to
set data link tables that allocate the same area for Area 1 and Area 2.

About this Manual:
This manual describes the installation, setup, and operation of the C200HW-CLK21, CS1W-CLK21-
V1, CJ1W-CLK21-V1, CVM1-CLK21, and CQM1H-CLK21 Controller Link Units for C200HX/HG/HE,
CS/CJ-series, CVM1, CQM1H-series, and CV-series PLCs, and includes the sections described
below. The Controller Link Units are used to connect these PLCs to a Controller Link Network. Infor-
mation is also provided in this manual on CS1W-RPT01/02/03 Repeater Units. The following three
manuals are directly related to application of the Controller Link Network.
Depending on the system, you may also need the CX-Programmer, or a Programming Console. Refer
to the body of this manual for details. Please read this manual and related manuals carefully and be
sure you understand the information provided before attempting to install and operate a Controller Link
Unit.
Precautions provides general precautions for using the Controller Link Unit and related devices.
Section 1 provides basic information on Controller Link Networks, and will give the reader an overview
of what Controller Link Networks can do and how best to use them.
Section 2 describes the basic procedures to use the Controller Link Unit. The settings necessary for
using each of the functions are also explained briefly. For more details, refer to the following sections
on individual functions.
Section 3 describes how to install a Controller Link Unit and how to wire the Controller Link Network.
Details are also provided on installation, wiring, and basic operating procedures of Repeater Units,
including information on using them to construct networks.
Section 4 describes the settings required for starting communications. These basic settings are
required for both data links function and the message service. Carry out the settings described here
before turning on power to the Controller Link Unit.
Section 5 describes how to use data links in a Controller Link Network. Refer to SECTION 2 Basic
Procedures for an outline of data link application.
Section 6 explains how to use the message service provided by a Controller Link Unit. It also explains
the FINS commands and responses supported by Controller Link Units and those supported by
C200HX/HG/HE, CVM1, and CV-series PLCs.

Intended Audience 1
1 Intended Audience
This manual is intended for the following personnel, who must also have
knowledge of electrical systems (an electrical engineer or the equivalent).
Personnel in charge of installing FA systems.
Personnel in charge of designing FA systems.
Personnel in charge of managing FA systems and facilities.
2 General Precautions
The user must operate the product according to the performance specifica-
tions described in the operation manuals.
Before using the product under conditions which are not described in the
manual or applying the product to nuclear control systems, railroad systems,
aviation systems, vehicles, combustion systems, medical equipment, amuse-
ment machines, safety equipment, and other systems, machines, and equip-
ment that may have a serious influence on lives and property if used
improperly, consult your OMRON representative.
Make sure that the ratings and performance characteristics of the product are
sufficient for the systems, machines, and equipment, and be sure to provide
the systems, machines, and equipment with double safety mechanisms.
This manual provides information for programming and operating OMRON
PLCs and related devices. Be sure to read this manual before attempting to
use the software and keep this manual close at hand for reference during
operation.
!WARNING It is extremely important that a PLC and all PLC Units be used for the speci-
fied purpose and under the specified conditions, especially in applications that
can directly or indirectly affect human life. You must consult with your OMRON
representative before applying a PLC System to the above mentioned appli-
cations.
3 Safety Precautions
!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 Provide safety measures in external circuits (i.e., not in the Programmable
Controller), including the following items, to ensure safety in the system if an
abnormality occurs due to malfunction of the PLC or another external factor
affecting the PLC operation. Not doing so may result in serious accidents.
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.
xxi
Operating Environment Precautions 4
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.
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 counter-
measure for such problems, external safety measures must be provided
to ensure safety in the system.
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 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 Confirm safety at the destination node before transferring a program to
another node or changing contents of the I/O memory area. Doing either of
these without confirming safety may result in injury.
4 Operating Environment Precautions
!Caution Do not operate the control system in the following locations:
Locations subject to direct sunlight.
Locations subject to temperatures or humidity outside the range specified
in the specifications.
Locations subject to condensation as the result of severe changes in tem-
perature.
Locations subject to corrosive or flammable gases.
Locations subject to dust (especially iron dust) or salts.
Locations subject to exposure to water, oil, or chemicals.
Locations subject to shock or vibration.
!Caution Take appropriate and sufficient countermeasures when installing systems in
the following locations:
Locations subject to static electricity or other forms of noise.
Locations subject to strong electromagnetic fields.
Locations subject to possible exposure to radioactivity.
Locations close to power supplies.
!Caution The operating environment of the PLC System can have a large effect on the
longevity and reliability of the system. Improper operating environments can
lead to malfunction, failure, and other unforeseeable problems with the PLC
System. Be sure that the operating environment is within the specified condi-
tions at installation and remains within the specified conditions during the life
of the system.
