OPC Services (DA & AE) do not take Service Status

Hello,

I am working on a small virtualized system. Recently 2 new connectivities were added to the system however the Services related to OPC (opcda and event collector) do not take the Service status, and in consecuence OPC server do not connect either. Have you experienced or seen this situation before? Any ideas of what could be the problem?

Any ideas would be appreciated.

Thanks

Best regards,

Valeria

This is the expected result if the OPC server does not return OPC_STATUS_RUNNING on the periodic GetStatus() call performed by 800xA DA Connector/Event Collector.

A DA server's health can be probed with the built-in advdsopcclient.exe test tool. Connect and look for the Status indication.

There is no onboard tool for probing AE servers. Internally we circulate "Mr Crilfe/Joines" test tools on request. Speak with closest support center.

The reason for not entering service state is to keep clients "away" from a not healthy OPC server.

All indicates that the new connectivities were not installed as connectivities so some features are missing. I will take care about that first. I will let you know. Thanks for the ideas.

It was very helpful to use the logviewer to realize about the differences between the processes running on the connectivity that was working ok versus the one that had issues

Please create a new thread if you like. Please try the advdsopcclient.exe tool; what OPC Server Status do you see? What OPC server? Logs?

dinoo31, in my case was resolved. But the porblem was that the "connectivities" were not installed properly. When I cloned a connectivity that I knew it was ok, I added the services and they run perfectly. A good way to know if it is working ok, is doing what Stefan says, check what information the logs tell you.

Hello,

Have you provided the controller entity in OPC panel for both OPC DA and OPC AE and check firewall are configured properly if you are using else try turnoff firewll in the control panel.
