A-5 Safety CPU Unit Status

The Safety CPU Unit status gives the operating status of the Safety CPU Unit. When a Safety CPU
Unit is placed on the NX bus of the Communications Coupler Unit, the status is displayed as an I/O
port in the I/O map of the Communications Coupler Unit. Also, when a Safety CPU Unit is placed on
the NX bus of the NX-series CPU Unit, the status is displayed as an I/O port in the I/O map of the CPU
rack.
If you set a device variable for the I/O port, you can monitor the status of the Safety CPU Unit from the
NJ/NX-series CPU Unit.
