Read tag id value

Ignition
1

Hi
For tag or UDT instance ignition generate unique tag id which can be seen in tag edit popup.
I want to use this tag I'd in my application but I wonder how can I read it in python.

All tag properties that can be read are read in the same way. The value is the default property, but you can specify others.

It would be something like this:

system.tag.readBlocking(['path/to/tag.propertyName'])

I’m away from my computer at the moment so don’t know what the actual property name for this is.

I mean this tag Id:

I tested many keywords but non of them worked.

Have you tried .uuid ?

5

Yes and it return nothing

What do you want to do with it ?

I believe that is more of an internal value for ignition and it's tag diagnostics. I do not believe that is a value that can be accessed via tag.browse or tag.read functions.

We want to use it a unique id for each device, and track the device with our client.
May be with some java class we can read it. Any idea on this @Kevin.Herron ?
