How can get (read) a variable from UDT defined in faceplate's tag interface in JS?

Hallo, 

 how can get (read) a variable from UDT defined in Tag Interface of FAceplate in JS?

I know how to get variable direct from Tag Interface but I need from UDT with : Faceplate.Parent.Properties."name of variable".Tag;

Split from Faceplate Interface Variable.

Hi, 

isolved this problem:

example:

let title = Faceplate.Parent.Properties.Interface.Tag;  // Interface is defined in Tag interface with Data type 'PLCUDT'.

So to access to the variable from UDT Type, we can write:

title+".ProcessValue" // ProcessValue is element of UDT
