1-2-2 System Configuration of Slave Terminals
A building-block remote I/O slave provided with a group of NX Units connected to a Communications
Coupler Unit is generically called a Slave Terminal.
The NX Units can be flexibly combined with a Communications Coupler Unit to achieve the optimum
remote I/O slave for the application with less wiring, less work, and less space.
The following figure shows an example of the system configuration when an EtherCAT Coupler Unit is
used as a Communications Coupler Unit.
Refer to the user’s manual for the connected Communications Coupler Unit for details on how to config-
ure the system when any other type of Communications Coupler Unit is used.
*1. The connection method for the Support Software depends on the model of the CPU Unit or Industrial PC.

A computer software application for setting, programming, debugging, and
troubleshooting NJ/NX/NY-series Controllers.
For an NX1P2 CPU Unit, this application performs setting operation by making
a connection to a built-in EtherNet/IP port.
