NX-series Digital I/O Unit User’s Manual (W521)
7-2 Specifications of I/O Data
This section describes I/O data for the Digital Output Units.
This section describes the allocable I/O data in the Digital Output Unit.
An I/O entry mapping is assigned to the I/O allocation settings for the Digital Output Unit except the Unit
that supports output refreshing with specified time stamp.
In the Unit that supports output refreshing with specified time stamp, one I/O entry mapping for input
and one I/O entry mapping for output are assigned.
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 EtherCAT Slave Terminal to an NJ-series CPU Unit, use
the I/O ports for the allocated I/O data.
