Wait for the digital signal

[Jani]

Is there like "wait for the panel activity" in digital signal, "wait for the digital signal goes up" etc. ?
Or is it bad to make it with sequence structure and inside of first sequence use while loop?

If you need to wait for a digital signal before continuing on with your program, the best way is to have a while loop that continuously reads the signal and stops the loop when the signal goes high. You can put this loop in the first frame of a sequence, or you can wire an output from the loop (like error out from the device read vi) into your next step. Be sure to put a delay (100mSec) in your loop so that the loop does not hog CPU time.

Thank you for your answer.
Second thing is that how much it makes charge to computer if i have like 5 different waiting loops at the same time?

As long as each loop has some time delay, having 5 loops won't make any noticable difference.
