Shut down while loop in subVI

[george seifert]

I need to shut down a while loop that contains an event structure in a subVI that runs parallel to my main VI.

I know I've seen this somewhere, but am not quite sure what to search for. Just a quick refresher of my options would be most appreciated. I've done it with a named timed loop that I can stop from the main VI, but somehow that seems clumsy.

A good option here is to create a user event, register for it in your event structure, and trigger it in your main VI. It would look like this (simplified to one VI with two loops):

Alternatively, if you already have a timeout case in your event structure, you could check the state of a notifier in that timeout case to see if the notifier has fired.

Perfect. Thanks.

And don't forget to close the Event with "Unregister for Events" outside the lower while loop
