I apologize. I just found that the enhanced diagnostics will only be in version 2022.2 which is not released yet, but will come out in probably less than a week.

What I was looking for was the datatype the server reports about that variable. Without having to wait for version 2022.2, can you run a small program similar to opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...d%20DataType%20attributes.html (change it t your server, and to the one NodeID you are dealing with - you do not need three variables as in the example). Notice that the program asks for the value of the UAAttributeId.DataType attribute and not the the default UAAttributeId.Value attribute.

Best regards

You just install the new version, make sure your project references the assemblies that come from the new version, and rebuild the project.

I have asked you about the Connectivity Explorer, but that is also the version of the QuickOPC library you are using.
So what I meant was to upgrade the library, primarily.

Hello. Thanks for more details.

The error message looks like from some older product version. In recent versions, we have enhanced it to contain more information needed to troubleshoot this kind of problem.

Which version are you using? (Help -> About)
