Is there any Ethernet/IP comms being used? Given its a CPU33 E/IP is onboard. If there is you will need to use network configurator to save the configuration if you want to have a backup.
James There is nothing there that requires any attention.
The analogue cards should have saved their configuration.
And as Chelton states are there any Ethernet I/P comms going anywhere?
Example - remote I/O with a NX-EIC202 Ethernet I/P interface?
