About this Manual:
This manual describes the ladder diagram programming instructions of the CPU Units for CS/CJ-
series Programmable Controllers (PLCs). The CS Series, CJ Series and NSJ Series are subdivided as
shown in the following figure.
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.
NSJ-series Controllers Equivalent CJ-series CPU Unit
NSJ@-TQ@@(B)-G5D CJ1G-CPU45H CPU Unit with unit version 3.0
NSJ@-TQ@@(B)-M3D CJ1G-CPU45H CPU Unit with unit version 3.0 (See note.)
Note: The following points differ between the NSJ@-TQ@@(B)-M3D and the CJ1G-CPU45H.
Please read this manual and all related manuals listed in the table on the next page and be sure you
understand information provided before attempting to program or use CS/CJ-series CPU Units in a
PLC System.
