iii CS/CJ/NSJ Series Instructions Reference Manual (W474)
About this Manual:
This manual describes the ladder diagram programming instructions of the CPU Units for CS/CJ-
series Programmable Controllers (PLCs) and the NSJ-series Controllers. The CS Series, CJ Series
and NSJ Series are subdivided as shown in the following table.
NSJ-series Controller Notation
For information in this manual on the Controller Section of NSJ-series Controllers, refer to the informa-
tion of the equivalent CJ-series PLC. The following models are equivalent.

OMRON Product References
All OMRON products are capitalized in this manual. The word “Unit” is also
capitalized when it refers to an OMRON product, regardless of whether or not
it appears in the proper name of the product.
The abbreviation “Ch,” which appears in some displays and on some OMRON
products, often means “word” and is abbreviated “Wd” in documentation in
this sense.
The abbreviation “PLC” means Programmable Controller. “PC” is used, how-
ever, in some Programming Device displays to mean Programmable Control-
ler.
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.

Omron Companies shall not be responsible for conformity with any standards, codes or regulations
which apply to the combination of the Product in the Buyer’s application or use of the Product. At
Buyer’s request, Omron will provide applicable third party certification documents identifying ratings
and limitations of use which apply to the Product. This information by itself is not sufficient for a com-
plete determination of the suitability of the Product in combination with the end product, machine,
system, or other application or use. Buyer shall be solely responsible for determining appropriate-
ness of the particular Product with respect to Buyer’s application, product or system. Buyer shall take

formance is subject to the Omron’s Warranty and Limitations of Liability.
Product specifications and accessories may be changed at any time based on improvements and
other reasons. It is our practice to change part numbers when published ratings or features are
changed, or when significant construction changes are made. However, some specifications of the
Product may be changed without any notice. When in doubt, special part numbers may be assigned
to fix or establish key specifications for your application. Please consult with your Omron’s represen-
tative at any time to confirm actual specifications of purchased Product.
Information presented by Omron Companies has been checked and is believed to be accurate; how-
ever, no responsibility is assumed for clerical, typographical or proofreading errors or omissions.

Unit Versions of CS/CJ-series CPU Units
Unit Versions A “unit version” has been introduced to manage CPU Units in the CS/CJ
Series according to differences in functionality accompanying Unit upgrades.
Some instructions are supported only by specific versions of a CPU Unit.
Confirm support before programming.
Notation of Unit Versions
on Products
The unit version is given to the right of the lot number on the nameplate of the
products for which unit versions are being managed, as shown below.
Confirming Unit Versions
with Support Software
CX-Programmer version 4.0 can be used to confirm the unit version using one
of the following two methods.
•Using the PLC Information
• Using the Unit Manufacturing Information (This method can be used for
Special I/O Units and CPU Bus Units as well.)
PLC Information
• If you know the device type and CPU type, select them in the Change
PLC Dialog Box, go online, and select PLC - Edit - Information from the
menus.
• If you don't know the device type and CPU type, but are connected
directly to the CPU Unit on a serial line, select PLC - Auto Online to go
online, and then select PLC - Edit - Information from the menus.
In either case, the following PLC Information Dialog Box will be displayed.

Unit Versions and Programming Devices
The following tables show the relationship between unit versions and CX-Pro-
grammer versions.
Unit Versions and Programming Devices
Note 1. As shown above, there is no need to upgrade to CX-Programmer version
as long as the functions added for unit versions are not used.
2. CX-Programmer version 7.1 or higher is required to use the new functions
of the CJ1-H-R CPU Units. CX-Programmer version 7.22 or higher is re-
quired to use unit version 4.1 of the CJ1-H-R CPU Units. You can check
the CX-Programmer version using the About menu command to display
version information.
3. CX-Programmer version 7.0 or higher is required to use the functional im-
provements made for unit version 4.0 of the CS/CJ-series CPU Units. With
CX-Programmer version 7.2 or higher, you can use even more expanded
functionality.
