I have a UDT instance that has a folder in its definition. I want to be able to add other types of UDT instances to this folder in run time is it possible?
I have been trying system.tag.configure, but I keep getting
The target path does not have item 'myNewTagName' for overrides, and cannot accept children tags.
Another way I could ask this question is how do I represent a list of tags in a tag? I was thinking I could make a folder in a UDT and then add and remove tags as necessary during runtime.
@Jonathan Did you ever figure anything out for this, I'm running into a similar issue. I'm able to create a udt instance, but when I try to write to a tag within the udt instance it instead creates a custom property and writes to that instead.

To write to a member tag of a UDT instance, you can simply use system.tag.writeBlocking()
. If you must do overrides on members within system.tag.configure
, you will need a nested tags
list of dictionaries with the properly formatted details. (Non-trivial, unless you work from system.tag.getConfiguration
.)
@pturmel I ended up working around it by using your suggestion to simply write to it after the tag is created.
