Device Specific error 7, Device specific error2.
I have a question for error status for AC800M PM 891 controller.
Error status is Device Specific error 7, Device specific error2...
This controller is some of alarm is not possible to acknowledge the system ararm and proecess alarm..
800xA 5.1 FP4 RevE used.
Device Specific Errors mean the errors are down there in the children of PM891 controller.
check out for errors in CI modules, I/O modules...
Not possible to ack alarms can be for many reasons. try removing controller from OPC A/E and readd it. restart event collector and alarm manager services. Check your user role if you have operator permission..
