How to take action when vi stops running

[eNaught]

Sorry for the newbie question but I can't seem to find the answer anywhere. How do I go about taking action such as turning off leds or reseting some variables when my vi stops running. Is there some sort of boolean flag that I can read to determine if the vi is running or a flag that gets set when the vi terminates? Thanks in advance.

Shouldn't your VI know when it has stopped running? If you have a loop around your VI then you know when it has stopped running - it's when the loop stops.

Or, are you using the Abort button on the VI? If you are, STOP right now. The Abort button is not supposed to be used for normal operation.

Thank you for your reply. I am using the abort button, this is just a simple vi that alternately flashes a couple leds and runs until someone stops it. I need all the leds to go off when the vi is stoped. I understand your point though, I suppose if I add a stop button to terminate the vi I can use that to turn off the leds also. Thanks again!

The state of the LEDs should not be important if the VI is not running (edit mode), it is however probably important that they are off next time you run the VI.

To make sure that indicators start out at the desired defaults when the VI starts running, go to "VI properties...Execution" and enable "clear indicators when called".

That is very helpful, thank you again.

Funny thing, I was wondering how to solve same problem.

If your inicator states are something other than the default, you can use property nodes to set them as well during your initialization phase.
