Hello,

I have a running ControlLogix Enhanced redundancy system: The first chassis has in Slot 0 the Controller, in Slot 1 the Redundancy Module and in Slot 2 a CNB Module (node 3). The second chassis has the very same configuration. The third chassis has in Slot 0 a CNB Module (node 1), in Slot 1 another CNB Module (node 2), in Slot 2 a DHRIO Module, in Slot 3 another DHRIO Module and in Slot 4 a 16 Digital Input Module.

What I don't know how to do is getting the entry status of the CNB located in the chassis that is running as Secondary.

Can anybody give me any clue?

Thanks!

Best regards
Fernando
