Yes, Understood. I have asked for possibilities for installation, temp licensing and configuration.

Note that it's not just the configuration - I need an installable of the server(s) too. Not always is this possible (licensing etc.). Let's see.

Helo,
thank you. Interestingly, I received no email from you; but this time, the attached ZIP file appears to contain all the traces and images, so we are fine.

I am already going through the traces and seeing some things, but let me ask first: Can these servers(+configurations) be provided to me for on-line troubleshooting here? Or is the problem confined to customer's computers? The issue is that the OPC analyzer traces have some limitations, and having the ability to debug this directly locally would be a big help.

Best regards

I sent the .ZIP file to your email. Please let me know if you did not receive it.

Also re-attached here just in-case.

Versions used: first 2018.3 and then version 2023.1.

Servers that the Demo application are browsing: Insight OPC Server and Siemens OPC server DSIGO

NOTE: The Insight server does NOT have branches.It is an older system that does not have a normal tree structure. The tags are listed one after the other without branches and leaves. The Siemens server does have branches.

Attempted to browse node items of both the Insight OPC Server and Siemens Server using the EasyOPCNetDemo (for both versions) the demo application times out after 5 minutes of trying.

When using the Matrikon OPC Explorer to browse the Insight OPC Server and Siemens Server, no time occurs and all .

I have attached the OPC Analyzer traces.

From the traces, when both clients QueryOrganization, the parameter namespace type is read as OPC_NS_FLAT. Then, when both clients BrowsOPCItemIDs the OPC Test Client sets the BrowseFilter Type to OPC_Flat with no permissions, but Matrikon sets its filter type to OPC_LEAF with ReadWrite parameters. Reason for this is unknown.

In the trace it looks as the browsing is successful, but for some reason the demo applications are timing out.

Lastly, we tested with OPC Expert. It was slower than Matrikon but was eventually successful.

Could you help me determine why there is a timeout when browsing from the demo applications? The expected result is to be able to browse items of both servers without issue.

Images of the exact error has been attached.
