Hello,

In the documentation here : Addressing external tags (RT Unified) • Configuring tags (RT Unified) • Reader • TIA Portal Information System, it says :

Indirect addressing via a screen object

In indirect addressing via a screen object, select the option "Screen object" for dynamization. If, for example, you select an IO field for this purpose, the content of the input field is adopted as the process value in the dynamized object property or at the parameter of a system function.

How can I do that ? I want to use indirect addressing to dynamize the Process value of an IO field, I know I can use a WString tag to do that (by selecting “Tag” dynamization), but I was wondering why I don't have the “Screen object" option for dynamization, as specified in the doc ?

I'm using SIMATIC WinCC Unified PC V20.00.00.00_00.00.90.11

Thanks you!
