RSLogix 5000 and devicenet

[Yiannis 1]

Hello everyone.

I have inherited a redundant FlexLogix system with Devicenet I/O. The secondary controller has faulted and I have to replace it. I have the primary program that I intend to download to the new secondary CPU after setting up the correct IP address. Do I need to do anything with RSNetworx for Devicenet? Reconfigure it or anything like that?
Thanks

There should be nothing to needed for the DeviceNet

I realize you've probably already done this, but wanted to chime in.

All A-B DeviceNet scanners store their configuration in nonvolatile RAM separate from the PLC program.   It's loaded into the scanner itself, and can survive power-down indefinitely.

I would be a little more cautious with a "redundant FlexLogix" system.    Any hot-standby or DeviceNet "redundancy" system will not be as easily integrated and reliable as true ControlLogix redundancy.

As long as the 1788-DNBO module (and the 1788-ENBT, for that matter) have retained their configurations despite the controller fault, they can be re-used without any reconfiguration.
