Knx commands in a for loop

[Ceros2112]

Hello,

I'm trying to make a "reset" function for a series of blind shutters, basically I want to read the actual state, and toggle the command in order to make the shutters move back and forth the actual position.

Everything seems to work fine in the script (I set logs and everything is good) except that shutters don't move 

So I wonder, is it possible to use knx commands in a for loop or there is some kind of limitation?

Thanks for your help.
