Hello,

I checked my old solution made in VBA in Excel which communicates with the same hardware. The program works fine with the same parameters (IP address and port) and the same tags . It is therefore not a communication bug.

The reference file in Excel, "OpcLabsEasyOpcUA.tlb" was created on November 11, 2020.

You get a screen print of the details of the attached file.

Thank you!

Eric

Hello,

Hello

The file attached is the screenshot of the properties of the OpcLabs.EasyOpcUA.dll file.

Thank you!

Hello!

I actually tried to do this operation but without success.

Last week my version of the software worked perfectly with the same parameters. Currently I have access to the HTML page of the OPC-UA server by the same IP address.

I also did the following tests:
a)
- Full Uninstall all the software (Quick OPC)
- Computer restart
- Rebuild
- Same error message without any library installed?
b)
- New software download
- Full installation
- Computer restart
- Rebuild
- Same error message

Hello Support team,

I am trying to test your actual Version 2020.2 but the included demo licence is no longer valid:

Not allowed to run by the license "Multipurpose". You might be using a trial license, and the version of the software you are using is obsolete. Obtain a recent version to resolve this problem. Component name: "QuickOPC", license IDs: "Multipurpose", version number: 558, release date: 06.04.2020, trial validity: 210 days, option expression: "EasyDAClient".

I need a functional test license quickly because I have a test to do with a customer shortly. If it works, I will have an order and I will purchase a full license.

Thank you,

Eric
