Re: [milo-dev] How to read properties or attributes from node

[José García Hernández <jgarcia@xxxxxxxxxxx>]

Hi Kevin,

Yes, we have Wonderware and InTouch servers and yes, I can see the properties only using a Wonderware client. We can subscribe to value changes of those properties by knowing the identifier and using your Java library, but it's impossible for us to list them using browse / read.

Regards.

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.

Regards.

If you can’t see these properties when browsing “Node1” then perhaps they aren’t actually being exposed via OPC UA by the server.

Can you see them using another UA client like UaExpert?
