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.
Series
CJ Series
CS Series
NSJ Series
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.
