Tag Object in Event Scripts Documentation

[deon.korb]

The documentation describes the modern approach to accessing parameters via the tag object:
paramValue =tag['parameters']['myParam']

https://docs.inductiveautomation.com/display/DOC81/Tag+Event+Scripts

A thread here alludes to some other properties:

Tag change script "valueChanged": tag object

Hi guys, This is a "PyTagNodeWrapper", but I couldn't find anything with that name in the docs. Is it even supposed to be exposed to scripts? This is just out of curiosity. I was trying to get to a BasicTagPath object to retrieve the tag's folder path, but it seems that system.tag.writeBlocking works with a relative path, so I didn't need it after all. [image]

I could not find any other documentation as to what else is contained in that object. I do a lot of string manipulation of the tagPath in event script to read properties, and I think some of those properties might be in the tag object.

Is there some more detail somewhere or even some kind of recursive introspection one can do on that tag object?

Most of the known properties are going to be from this list of constants:

You can always dir() the object to do introspection at runtime. It looks like tag.getPropertyModel().getProperties() will also have a pretty complete list from the runtime object.

Thanks. I'll have a look to see if there is something I can use rather than tag reads
