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 an EtherCAT Coupler Unit, the status is displayed as an I/O port in the I/O
Map of the NJ/NX-series CPU Unit. If you set a device variable for the I/O port, you can monitor the sta-
tus of the Safety CPU Unit from the NJ/NX-series CPU Unit.
