System Configuration of Slave Terminals

Slave Terminal is a generic name for a building-block remote I/O slave that contains a group of NX
Units connected to a Communications Coupler Unit.
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 a Communications Coupler Unit other than an EtherCAT Coupler Unit is used.
