Hi,

You may close this case. It was a problem in my code.

Thank you.

Hello.

In your test, is the tunneller actually connecting to a different (remote) computer, or is the DELL-I7MIKE your own (client-side, with QuickOPC) machine?
And in the customer's test?

I am unable to upload the PNG file.
The full error is: "Timeout browsing nodes. The client method called (or event/callback invoked) was 'BrowseNodes'.

Hi,

My client did the same test on his computer (same configuration) and got a different error: "Timeout browsing nodes".
See the attached screen capture.
I asked him how many items are in the OPC server. Waiting for answer.

Thank you.

Hi,

I have QuickOPC 5.63.232, and Matrikon OPC Tunneller v.6.3.6.8582 installed on my computer. When I try browsing for items using the Tunneller:DELL-I7MIKE:Kepware.KEPServerEX.V6 server, it takes very long time and then I get this error.

Using Matrikon Explorer, browsing works fine. Can you please advise what should I do?
