refer to the attached file, the digital I/O will be on once the vi is run. This is due to the Constant True button is wired to the data line.

 

How to off the digital I/O, once the stop button is pressed? Any good idea?

Hello,

 

When "Stop" is pressed, the while loop will stop and then the "Clear task" will execute, so it is between the two that you should insert another "Write" with a false linked to it.

 

But maybe you could also do that :

This is a snippet (vi save in a png file), download the png file and drag and drop it to your VI's diagram.

 

By the way this is in LV 2010, which version do you have?

Whats the " grey-white colour" loop? How to write " stop": value chang" ? It's an event structure, it can detect events that you register for. To register for an event you right clic on the frame and select "Add event case" then comes a windows in which you can set the event you want to catch, the most used type of events is the "value change" on a control, so first select the control from the list and them select the "value change" event.
