Expression read tags on level before

Ignition
1

Hello Ignition’s black belt :slight_smile:

Ignition 8.1.3
I have a UDT (UD1) that contain an instance of another UDT (UDT2).
I would like to add a tag in UDT2 that will read a tag from UDT1.

How do I do that?

Thanks.

Could you better explain what you are trying to do?

I’m pretty new my self, so this might not be the best answer. But I can’t think of a reason off hand one udt would read from another.

I’m thinking you want to look into indirect addressing/ creating a template which could read from multiple udts. and use that template for your end goal.
