CJ-series Special Unit Devices
If the device is a CJ-series Special Unit, I/O port names are determined by the model number of the
Unit and the functionality.

Device Variables

In an NJ-series Controller, external devices (slaves and Units) are not assigned to specific memory
addresses in the CPU Unit. Rather, variables are assigned to the I/O ports. These variables are called

device variables.

Slave and Unit Configuration
Information created.
Slave and Unit Configurations
You can specify device variables in the user program or in external communications to access the
devices (slaves or Units).
