Access UDT parameter in script

[zxcslo]

Well... then I'm 'lost'...
In my case, when I drag from OPC browser the UDT (struct) tag from my S7-1500 OPC UA server, that tag is Unicode string type (JSON). You obviously get Document type.

I'm using v7.9.12. You're using v8.
In v8 system.tag.read is deprecated (but it'll still work, for backward compatibility). The new function is system.tag.readAsync.
Maybe system.tag.read was changed in v8...??? Maybe @Kevin.Herron can explain?

EDIT: I read the other post it again and it seems that, because tag system is completely changed in v8:

@Kevin.Herron

edit: the Document object in our tag system might be a mutable GSON object and not a String… I’ll have to look at this in a bit when I get the office.
