In the caller VI, attach an indicator to the iteration terminal (the blue i) and run your code. Does the value increase while you're running?
--> I said already twice that i did that and that it was changing
Have you used highlight execution in the subvi to see what you output?
--> now i did and yes that helped 😉
Attaching the code doesnt help or? U need the device a driver installed?!
Anyway it works now 🙂
