Types of NSJ Controllers

Differences between
Types of Controllers
• Connect CJ-series Expansion Racks to use any required CJ-series Units.
An NSJ I/O Control Unit can be mounted to the back of the NSJ Controller
to connect up to three CJ-series Expansion Racks with a total of up to 30
CJ-series Units (10 Units per Rack). Any of the CJ-series Basic I/O Units,
Special I/O Units, and CPU Bus Units can be mounted to the CJ-series
Expansion Racks.
• If an NSJ I/O Control Unit is not mounted, either an NSJ Controller Link
Unit can be mounted to add a Controller Link port or an NSJ Ethernet Unit
can be mounted to add an Ethernet port. This enables either connecting
to a host via Ethernet or connecting to the pier-to-pier Controller Link net-
work. Seamless communications are possible to integrate information
with the host or with other production lines.
Using the ladder monitoring function makes it possible to monitor the execu-
tion status of programs in the Controller Section or in other PLCs without hav-
ing to use a Programming Device, such as a CX-Programmer or Programming
Console.
Special screens are provided on the Display Section that enable monitoring
the Controller Section or DeviceNet master functionality of the NSJ Controller.
Error information and countermeasures can be displayed. The alarm monitor-
ing function of the Display Section can also be used to automatically switch to
the special screens when an alarm occurs.
The System Menu of the Display Section can be used to back up Controller
Section data onto a Memory Card.
There are two types of NSJ Controllers, as follows:
• NSJ@-@@@@(B)-G5D
• NSJ@-@@@@(B)-M3D
The following points are different in the Controller Sections of NSJ@-
@@@@(B)-G5D and NSJ@-@@@@(B)-M3D Controllers. (The Display Sec-
tions are identical.)
