Dear Mgfeal,
Good day!
The right controller has degraded health condition which might be contributing or causing loop issues. There is no DP-1A or DP-IB LEDs either.
The connection status is:
Right controller DP-1B (O) > Enc 5 P1 (O), P2 (G) > Encl 4 P1 (G), P2 (G) > Encl 2 P1 (O), P2 (F) > Encl 6 P1 (G), P2 (G) > Encl 1 P1 (F), P2 (G) > Encl 3 P1 (), P2 () > Left controller DP-1B
*O=Off, G=Green, F=Fault.
*Not sure of encl 3 right IO P1-P2 LEDs. Hence, blank above.
*On Encl 3, left IO, the P2 is off, if cabling is right, it should be connecting to right controller DP-1A.
The loop 1B is disrupted. If any IO module or cable is malfunctioning, the loop error would traverse across the components on loop.
I would request log file (and above missing LEDs) to verify array hardware status. It would help us pproceeding methodically.
Also, do you have spare IO module or cable at site?

Vikash
