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.

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.
