I hope you're doing well. Is there a way for me to independently check the QuickOPC version tied to our license? If not, could you kindly provide the version details at your earliest convenience?
Thank you for your assistance.

The EasyUAApplication has been introduced in QuickOPC 2023.1 (5.71), so you need this or newer version (kb.opclabs.com/Versions ).
It works in general with any QuickOPC edition. The parts that are limited to Enterprise Edition are those that have to do with CA-generated certificates, using OPC UA Global Discovery Server (GDS) and Certificate Services (CM).
So far you have not indicated that you have to use the GDS in your system. It looks like that you are using self-signed certificates. For that, any edition is sufficient.
Best regards

Furthermore i found this table(attached) where it looks like this functionality is only avalible in Entreprise version, this is right?

Yes, the length of validity period of the auto-generated client certificate can be changed. See e.g. opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...%20Instance%20Certificate.html . In the part "Instance Certificate Auto-Generation", it describes properties like MaximumExpirationDate and ValidityPeriodInMonths, and there is even an example showing how to do it (note that the example removes the old certificate first, in order to prove the point; but then it would re-generate it every time the app runs, which is not what you want, so the part that removes the certificate will not be in your code, at least not regularly executed).
You can also generate the whole certificate externally use some custom tool, and then let QuickOPC just use it.
To your other question, all our product edition/license types include OPC "Classic" Data Access (COM/DCOM-based).
I hope this helps.
Best regards

What is PDA? Is that you OPC client app?

When we establish a connection against the PLC it creates directly the PLC certificate and another one for the PDA.
When the PLC certificate is generated, it allows us to change the validity date.
The first question was if there was any way to change the validity date of the auto-generated certificate of the PDA.
And the other question, was that if with the license that we have contracted, we have access to the OPC DA.
I look forward to your answers.
