I had a similar situation with Cohens Data Hub OPC software. Service started only after PC reboot, but then I couldn't open for edit Cohens Data Hub.
Which software you use to get data from equipment or it's already has an OPC.
If its possible install TopServer or kepware OPC and read data from equipment to OPC and from OPC to ABB.

The 800xA OPC DA Connector service run as service/background process which is not the same as an OPC client running as a desktop application.
Eg any GUI drawn by OPC server will fail the connection since background processes may not interact with the desktop.
The OPC server must support asynchronous OPC methods.
The service account must permit DCOM callbacks from the OPC server.
Enable the error logs on the OPC DA Connector service in AfwApplogviewer; reason for failure should surface there.
Ask regional ABB for assistance with troubleshooting.

Hi,
In the DCOM identity of the OPC Server you are trying to connect, add the user account from which you are able to read the values in Matrikon. Then try to create Service it will be in service.
