Stange behavior of Alarm -800xA 5.1
I have a question about alarm indication of objects. Please refer to the attached screenshots.
Library used is signal library. You can see from the screenshots differential normal is active but it is not giving any alarm.
OPCDA and AE indications are smiley. All services are in service state(green). I couldn’t find a wrong configuration.
ABB MMS Server for AC800M/C : StartupType=Manual,Log on as : 800xAService
ABB OPC Server for AC800M : StartupType=Automtic,Log on as : 800xAService
Interesting thing is if you force the signal and change the Input status then remove the force then it will generate the alarm.
Let me know if you have any suggestions to fix this issue.
Note that the controller cyclic load is 65%. Is it came out of the controller load ?
