So is this a Wonderware server you’re connected to and you can only see these properties within Wonderware software?

Hi Kevin!
I cannot see the attributes with UAExpert nor Prosys clients, but can see them with Wonderware. Let me add an attached image.

Can you see them using another UA client like UaExpert?
