Bad status of two computers out of 26 IT OPC Server Network in System Status Viewer
In System Status Viewer 2 computer out of 26 computers in IT OPC Server Network begin to show "red" status.
When we check IT Control Connection we see that Summary Alarm get value "KeepAliveFailure" and quality "bad". Also have "bad" status Time and Description.
Remaining node are having Good Status.
Restarted the IT OPC service from the Service Structure and SNMP Service from windows service in the PNSM Server.
I'm don't have any vast experience of PNSM Basic Computer Monitoring, but as far as I can tell it makes use of 2 (two) OPC Properties:
1. ResourceAlert (string): "Normal" or "Bad" (+some text, e.g. "Node Down") which is shown in the faceplate.
2. ResourceAlert-Value (integer32): 0 (good), 1 (error) or 2 (warning) to drive an Alarm Expression.
My reference system has Bad quality set on 3 other properties, but is still working as it should (as far as I can tell).
I suggest asking regional ABB to spawn a support case if you need assistance with troubleshooting PNSM.
We are using Device Status to indicate in the Display Graphics, which shows Red even if Node is healthy.
Device Status will show Red if there any Active alarm in the alarm list,Now the alarm is there because of asset monitor is getting bad input quality for keepalivefailure.
Thanks for the support provide, i will create the supportline case..
