Hi jasper,
you stop a VI either by
- reading a stop button frontpanel element, connected to the stop condition of a loop in your VI
- clicking the stop button in the VI menu bar to abort your VI
To (re)start your VI you click the run arrow in the VI menu bar.
Did you take the Training resources to actually learn this basic LabVIEW knowledge by now?
Best regards,
