A-6 I/O Ports of Safety I/O Units
The I/O ports of the Safety I/O Units are displayed on the I/O map of the Communications Coupler
Unit if you place the Safety I/O Units on the Communications Coupler Unit. When you place the Safety
I/O Units on the NX bus of the NX-series CPU Unit, their I/O ports are displayed on the I/O map of the
CPU Rack.
The names of the I/O ports that correspond to the data in the I/O Map of the Safety CPU Unit are giv-
en in the "Corresponding port name" Column. "Same" means that the same name is used.
