How can I de-energize the channels at the end of the test?

Hello,

I am controlling multiple solenoid valves in a cyclic manner by energizing them cyclically inside a loop. I am new to the labview and I am not sure how I can have them all de-energized once a certain criteria is met. At this point, once the criteria is met, the loop stops, but some of the valves remain open. Any help would be appreciated.

After the loop, you just write FALSE to all of the digital outputs.  Then you can close the task(s).
