Hello,
My associate and I are trying to sync up two ControlLogix racks (7-slot chassis) with identical modules. We are able to see the secondary rack increment the IP's of its two ethernet modules (+1 on each of the last octets as they should), however the secondary does not qualify and always shows "DISQ". We are unable to get these things to resolve even though we have done so on similar setups without the EN2TR being involved.
We have two identical ControlLogix 1756-L82e racks set up as follows:
(7 Slot Chassis)
Slot 0: 1756-L82e (CPU, v34.014)
Slot 1: 1756-RM2 (Redundancy module)
Slot 2: 1756-EN2T (Ethernet module, v 11.004)
Slot 3: 1756-EN2TR (Ethernet module, v 11.004)
We have both fiber pairs connected between the RM2 modules (two LC pairs, redundant). We have tried connected CAT5 cables between the EN2T's for example (EN2T in Rack A to EN2T in Rack B) and the same for the ENT2R's, always with similar results.
Previously, we were getting an error that the EN2TR was not set up for IP swapping capability. However we fixed this by setting the IP of the EN2TR to a different IP than the EN2T. We are now getting no errors, and all connections show Full Compatibility, but Disqualification.
Does anyone have any tips or tricks we can use to try to get these things sync'ed up? We have tried Time Sync, power cycling, disconnecting all other equipment, etc and are about out of ideas.
Any help is appreciated, thanks.
