Hi,

1. Yes.
2. Yes. Both client and server on the same computer.
3. Always.
4. No. The problem on different machines.
5. I will ask the customer.

Thank you.
Michael

Thank you for this.

Additional questions:
1. This is the problem for which you might be able to give us a remote access to the machine, is that right?
2. Both the client and the server are on the same computer, is that right?
3. Does this happen always with this server on this machine, or just sometimes?
4. Does it work correctly with the same server on some other machine (or, "don't know")?
5. Will the remote access be for extended periods of time and with ability to repeatedly install our tools? It is likely that we may need to go back, add some logging, product a new QuickOPC build, retest, and so on.

Best regards

Browsing the DeltaV OPC server fails - "Object is not connected to server" was created by micham
We are using QuickOPC.Net version 2018.2. We have a problem when trying to browse the DeltaV OPC server (opcda.OPC.DeltaV.1). When trying to browse, we see the error:

Object is not connected to server. See the attached screen capture.

Note: We don't have a problem to browse for OPC items with any other OPC server.
Your help is mostly appreciated.

Thank you.
