I am starting to work with scripts in Tia Portal v12 for program my TP1200 and I dont find a basic feature of scripting for these panels. I need a cyclic script to check the status of a variable. For this I am using a clock variable of a PLC (1hz) for run the script in the "Value Change". But the script dont work. For test if i made a mistake in the programming of my script I created a button that runs this script in the "click". However here it works right.

I have a similar problem as the guy ofthis thread, but with WinCC Confort (here I dont have "Global Script Runtime" ).

How can I run a script cyclically?

Thanks.

The acquisition cycle is set to 100ms. I ensure the panel is reading right the tag with a "led" in the screen. I attach an image of the actual configuration of the tag.

Thanks.
