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.
Please read this manual and all related manuals listed in the table and be sure you understand infor-
mation provided before attempting to program or use CS/CJ-series CPU Units in a PLC System or an
NSJ-series Controller.
Precautions provides general precautions for using the CS/CJ-series Programmable Controllers
(PLCs), NSJ-series Controllers, and related devices.
Section 1 describes the basic information that is required to use programming instructions.
Section 2 provides a summary of instructions used with NSJ/CS/CJ-series PLCs.
Section 3 describes each of the instructions that can be used in programming NSJ/CS/CJ-series
PLCs. Instructions are described in order of function, as classified in Section 2 Summary of Instruc-
tions.
Section 4 provides instruction execution times and the number of steps for each CS/CJ-series instruc-
tion.
The Appendices provide a list of instructions in order of the mnemonics and an ASCII table.

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 shall not be responsible for conformity with any standards, codes, or regulations that apply to the
combination of products in the customer's application or use of the products.
At the customer's request, OMRON will provide applicable third party certification documents identifying
ratings and limitations of use that apply to the products. This information by itself is not sufficient for a
complete determination of the suitability of the products in combination with the end product, machine,
system, or other application or use.
The following are some examples of applications for which particular attention must be given. This is not
intended to be an exhaustive list of all possible uses of the products, nor is it intended to imply that the uses
listed may be suitable for the products:
• Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or
uses not described in this manual.
• Nuclear energy control systems, combustion systems, railroad systems, aviation systems, medical
equipment, amusement machines, vehicles, safety equipment, and installations subject to separate
industry or government regulations.
• Systems, machines, and equipment that could present a risk to life or property.
Please know and observe all prohibitions of use applicable to the products.

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.

CJ1-H/CJ1M CPU Units
User programs that contain functions supported only by CPU Units with unit
version 4.0 or later cannot be used on CS/CJ-series CPU Units with unit ver-
sion 3.0 or earlier. An error message will be displayed if an attempt is made to
download programs containing unit version 4.0 functions to a CPU Unit with a
unit version of 3.0 or earlier, and the download will not be possible.
If an object program file (.OBJ) using these functions is transferred to a CPU
Unit with a unit version of 3.0 or earlier, a program error will occur when oper-
ation is started or when the unit version 4.0 function is executed, and CPU
Unit operation will stop.
