8-2 Specifications of I/O Data
This section describes I/O data for the Digital Mixed I/O Units.
This section describes the allocable I/O data in the Digital Mixed I/O Units.
An I/O entry mapping is assigned to the I/O allocation settings for the Digital Mixed I/O Units.
A specific I/O entry is assigned to the I/O entry mapping for each NX Unit model. These allocations are
fixed, so you cannot add others or change them.
An I/O entry means the I/O data described in this section. An I/O entry mapping means a collection of
I/O entries.
To assign the I/O allocation information of the NX Unit or Slave Terminal to an NJ/NX-series CPU Unit
or NY-series Industrial PC, use the I/O ports for the allocated I/O data.
However, for Slave Terminals, I/O ports may not be used depending on the type of communications
master or Communications Coupler Unit.
Refer to the user’s manual for the connected Communications Coupler Unit for details on how to use
I/O data for Slave Terminals.
