Hello,
I am glad that it works. Thank you for letting me know.

QuickOPC 2020.3 was released on December 3, 2020. That's not that long. Only a portion of users make an upgrade really fast. And yes, OPC UA complex structures are not commonly used. What's more, as you have noticed yourself, the problem depends on the data. It may not appear with some servers or configurations at all.

Best regards

This problem appears to have been resolved.
I hope there are not more errors.
Apparently I'm the only one who uses complex structures with OPC-UA, because this problem should have been noticed long ago.

Thank you. TeamViewer would only be of limited help; let's see how it works out. I have made the change that should hopefully fix the issue. Please download and install latest QuickOPC 2020.3 from www.opclabs.com/products/quickopc/downloads , and verify that it is build 5.59.1023.1 or later. Rebuild your project with it, retest, and let me know the outcome.

This assumes that you are building against the assemblies taken from the Setup program, and are not using the NuGet packages on www.nuget.org for build - they have not been updated yet. If you need them, let me know.

Best regards

Hello.

In order to reproduce the problem, I would need access to the PLC with your configuration, and I do not have that currently.
But, it is possible that we resolve the issue without the need to reproduce it. I have reviewed the related changes between versions 2020.2 and 2020.3, and found a possible problem by inspecting the code.

I will prepare a new build of 2020.3 which will hopefully fix it. Please allow some time for it. I will notify you here on the forum when it is ready. Thank you for reporting the problem.

Best regards

Das Problem ist in Strukturen die Arrays enthalten, aber nicht bei allen.

Sie sollten das Problem mit meiner Struktur nachstellen da dies wirklich ein schwerer Fehler ist

Hello,
can you please provide some information?

1. What is the last version that has worked - was it QuickOPC 2020.2, or something older?
2. Can you still run you program built with the same version , and does it still work today? (just making sure that the problem is truly in the change in QuickOPC and not in some change elsewhere).
3. Can you send me or somehow what is an example of correct (expected) data read, from the old version?
4. What precisely happens with QuickOPC 2020.3? Do you get an error? If so, what is the error? Or are there other symptoms?

Best regards

P.S. For easier work, I am attaching the picture from your document right below.
