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 con-
figure the system when any other type of Communications Coupler Unit is used.

Item
The Unit that serves as the center of control for a Machine Automation Con-
troller. It executes tasks, refreshes I/O for other Units and slaves, etc. NX
Units can be connected to an NX1P2 CPU Unit.
The NX Units perform I/O processing with connected external devices. The
*1
NX Units exchange data with the CPU Unit through I/O refreshing. A maxi-
mum of eight NX Units can be connected to an NX1P2 CPU Unit.
The End Cover is attached to the end of the CPU Rack.
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 mak-
ing a connection to a built-in EtherNet/IP port.
