Igniton 7.9 creation of new tags in Instances

General Discussion

Hello guys,

I am new to Ignition 7.9 platform and I have a question, maybe you cand help me a little.

If I want to create new OPC tag in an Instance folder of an UDT, what is the best practice procedure to do that? I noticed that I can’t create new tags in Instance folders, only outside that folder, or in the Instance folder only.

For example: I have a thermal point named PT730, and inside of it I have many folders, for: temperature, pressure and flow. And let’s supposed that I need to create a new tag in temperature folder. When I click on that folder I get erros message: “New tags cannot be created in UTD instances”.

Can you help me with a hint please?

Thank you in advance!!

Well, you can’t. You would need to define a UDT that used the original UDT as its parent and includes your desired extra tags. Then replace the original UDT instance with an instance of the new type.

You could save a backup of your current state, then roll back to a previous backup where the tags are present, then export them. Then restore to the current state and import them?
