Do I always need a Tag Provider to expose my (memory) Tags?

I suppose so?

We would like to replace our OPC-UA server implementation by Ignition.

At the moment I expose the memory tags by:

  • Enable the “Expose Tag Providers” in the OPC-UA settings
  • Create a Realtime Tag Provider like e.g. [NewProvider]
  • Create the memory tags for [NewProvider] using system.tag.configure in Web Dev Python resources
  • Read/write the memory tags using system functions…

In our current OPC-UA server implementation the tags are created directly in i=85 [ObjectsFolder] whereas in Ignition they are created in ns=2;s=[NewProvider].


Do I always need the Tag Provider and have this starting point [NewProvider]?
