Hi, thank you , yes it works on the latest version.

Hello.

There is built-in trial license that delivers valid data for 30 minutes each time the process is run.
Separate evaluation key is only needed if, for your evaluation, the above time is not sufficient.

Regards
 

No problem kindly share the evaluation key please.

There can be a bug in the older version. As I wrote, we no longer support it.

Test the same with the recent version. If ti works, purchase a version upgrade.

Best regards
 

Hi,  Unfortunately our current perpetual license is  expired only support up to 5.61, please advise it this might be one of reasons the sdk code provided doesnt work.

Hello.
version 5.61 is no longer supported. If you get the same error with the current version, report it here and we will diagnose it.

The information about the attributes is already contained in the result of QueryEventCategories, so the call to QueryCategoryAttributes is not needed. See this example:

opclabs.doc-that.com/files/onlinedocs/OPCLabs-ConnectivitySt...%20an%20event%20attribute.html  

Best regards
 

Hello.

This example shows how to specify which custom attributes should be delivered with each event category:

opclabs.doc-that.com/files/onlinedocs/OPCLabs-ConnectivitySt...ieve%20attribute%20values.html

I hope it helps.

Best regards
