Hi Defreitas, Maybe you will need to change the filename (Path) in the logix designer project that you download to the PV as well. -------------------------------------------

Doubt it, considering the RM2 communicates through the bus. But you can try. A power cycle after assigning IP may do the trick. Let me know.

Power Down One Chassis: Start by powering down one of the redundant chassis. This ensures that only one chassis is active at a time, preventing IP conflicts during the configuration process. Remove the Redundancy Module: Remove the 1756-RM2 module from the active chassis. This step is crucial ...

you need to set one to .10 and the partner incremented by 1 ie .11 They cant be the same but the RM2 will handle the changeover.

Are you using a 1756-RM2?

Hi John, In logix designer is the module configured to be single ended or differential current? You are likely correct that the problem is ground loops, depending if you can afford to lose the capacity, set the 1756-IF16 as differential current input, meaning each channel has an isolated RTN. ...
