How to auto start again when script stopped?

In the normal case the SCript should not be stopped without a error...i run many scripts and some for many hours.

Maybe there is an error in your Script with no expection?

in my most scripts i work with a while loop and its working great.

Settings: Automatically start service / Automatically run script start when starting service? (<--- thats not the function you need I think..its starting your scripts, after starting the service)
