Message: Network connection to OS1 lost, Condition: Network connection error, Area 1
We use ABB 800xA system Ver 5.1 & having a total 4 workstations (i.e. 3:OS & 1:ES). today suddenly OS1 has been hanged i.e. all the AI's were not varying, also the mouse was not responding.
I have checked the workplace Event list from the ES1 and it is showing the following message:
Message: Network Connection to OS1 Lost, Condition: Network Connection Error, Area 1, Sub condition: Network Connection Down.
The Error message indicates that ES1 detected that OS1 failed. It tells you nothing usefull about why OS1 failed.
There are a couple of million possible reasons why the "mouse isnt responding" ranging from the CPU being completely overloaded to the mouse being unplugged. But in your case it looks like your problem is ~microsoft windows~. i.e. something broke and the workplace hung.
Without more error messages and diagnostics theres not much more we can tell you. I assume you rebooted the station and the problem went away ?
What else exactly happened ? Did you check the CPU load and memory ? Did you get a red box in the top right allowing you to restart the workplace ? Have you got the workplace crash dump handler enabled ? are there any other windows logs ? event logs ? system messages ?
