Hi Experts,
I got a 1734-ACNR failed on-site recently. I have replaced it with a new ACNR (node number and chassis size configured) but can't fix the problem.
As the system has been running for over an year (no update recently), it should not relating to programming/configuration issue I guess.
The ACNR modules status LED keeps flashing green and PointBus LED keeps flashing red simultaneously. Both channel A & B, System Power and Field Power LED are solid green.
The ACNR carrying totally 19 modules (IB8 and OB8 only) with 1 EP24DC in the middle. All IO modules modules status LED are solid green but network status LED keep flashing green. For the EP24DC, all LED on it are solid green.
There are other ACNR connecting to the same frontal and those are working just fine. The frontal is a ControlLogix L61 (16.54) with redundancy.
The ACNR replaced from site was tested on test platform and working so I am guessing something to do with TB, IO modules or EP24DC.
Any suggestion is appreciated.
