HI Redundant Controller goes in fault on download?
I am working on a 800xA System redundant HI controller (PM-865A) and I am facing the issue that sometimes that I download(mostly cold start) on the controller; the controller goes in fault. The controller and SM811 module of both the units goes in fault. This occurs when the controller is "Sending Domanins" for our application?
Any advise on the probable reason for this would be greatly appreciated since even though we are in engineering status at the moment, we cannot proceed until we iron out this problem?
