I am continuing work on my energy meter project on a shared Ignition server with multiple users. It seems a good idea to move my energy meter UDTs and instances from the ‘default’ provider into my own tag provider ‘tp_BA_Energy’. This way I can protect the tag definitions with role-based security and prevent other users from ‘improving’ them.
As a first attempt I copied the UDTs (in Data Types) and all the meters into my new tag provider as shown below.
- Now I find that the originals still work but the copies don’t. All the tag quality values are 'Unknown".
- If I add tags to ‘tp_BA_Energy’ (my new tag provider) they also appear in the default. It’s as though my tag provider is just an alias for the default one.
Can anyone give me a pointer?
