800xA 5.1 OPC shutdown periodically
800xA system in the site consists of ASCS1,ASCS2 by redundant, Windows 2008 Server (32bit), 800xA 5.1 RevA FP1, RAM 4GB and total tags are 6,000.
OPC DA Connector service for one of the both servers is shutdown approximately every 1 year periodically in the site. So, In order to prevent unexpected problem, I recommanded periodic shutdown every 1 year. But, customer didn't accept it and they is about to upgrade 800xA to the latest version of 5.1 or 6.0.
At this point, do you know this cause?
if you uprade, what is your suggestion for upgrade mathode?

There could be many normal reasons for an OPC DA Connector restart.
The OPC DA Connector is in itself acting as an OPC client and it continuously monitors the OPC server for health, and will disconnect and restart if:
a) the OPC server terminates
b) if a bad status is returned
c) supervision timeout occur
d) if the OPC server requests a shutdown
The server status can also be manually checked with the built-in advdsopcclient.exe tool of System 800xA:
For proper operation, "Running" must be reported:
Also, take a look at the [Service Structure]Services:Service Event List. In fact, copy that event list down to the OPC DA Connector service, or an individual group or service provider and call it there to get a filtered list. You can also right click any column, e.g. "Message" and type a view filter, e.g. "OPC DA server*" as I did in the image below.
Look for the events emitted during a malfunction. You should see messages like:
OPC DA server stopped. The OPC Server terminated unexpectedly!
OPC DA server shutdown request.
OPC DA server stopped. Supervision timeout.
All of the above are restarts initiated by the OPC server itself, not System 800xA.
If the connector "crashes" it often leaves an exception trace in the below file (look for the last pages and see if date & time matches up with the occurrence):
C:\ProgramData\ABB\Process Portal A\Log\Exception_CrashHandler_AdvDsOPCConnector.log
If this is the case, consider turning on "Dump On Exception" to catch a full memory dump next time a crash occur. Crash dumps can be investigated by R&D. Please consult your regional ABB support center.
Besides the above, the average life time of a Microsoft Windows operating system is typically not more than a year. A quarterly or semi-quarterly reboot is not uncommon.
