COMMUNICATIONS FAILURE ON ROSEMOUNT OPM2000A, OPM2000R, OPM2001

Communication failures typically fall in to 2 categories:

1. bad interconnecting wiring

2. board faults

If you’re not using Belden 8162 or 8163, you run the risk of causing a communications problem that gets worse with time.

The LON originates on the Stack LON board AND the IG-1 serial gateway. If either board is faulted, unpowered, corrupted, blown power supply,  or whatever then you’ll get COMM FAULTS.
