Hi,
you could do it like:

let ind = 0;

let tag1 = Tags("FromHMI_ar["+ind+"]");

let tagValue1 = tag1.Read();

Screen.Items("Text box_2").Text = tagValue1.toString();

Hello 

this is only for WinCC Unified (Javascript).

for WinCC Comfort/Advanced you have to use VB Script.

Here you can find some hints:
