Hello all, I'm having issues with multiple 171CBU98090 momentum processors. They are programmed to read Modbus ASCII via XXMIT block from two devices ever 5 seconds or so to poll data on 10 Modbus registers. The processors run without any issue for a months and out of nowhere they go in to halt. Does anyone know what may be causing this? I contacted tech support many times over the years but all they could recommend is to update the firmware, which I did and issue persists. thanks!
