flashing stacked sequence auto start and stop

[tbob]

If you want to stop the while loop programatically, just wire the condition into the stop sign.  In your case, I am assuming that you want to stop after the 5th LED gets lit.  So wire the 5th LED boolean to the stop sign.  See attached vi.

My idea is to have the led's turn on then off sequentially, until my test data is plotted. I use a DIAdem Open Ref.,DIAdem Run Script, then DIAdem Close Ref. This takes between 10-15 seconds. I was hoping to display the LEDs during this time period then programmatically stop the LEDs and continue processing with in the frame structure.

Attached is my LED back and forth vi. Works fine as a stand alone but when I save it as a subVI and call it up in the main vi it acts differently. The LED's just run in one direction!

Am I understanding correctly.  You have a series of VI's operating in series.  After each VI, you want the next LED to turn on to show the progress.

I think an action engine would work.  Each time it is called, it runs once and turns on the next LED and turns off the rest.  You keep track of the next LED in an uninitialized shift register.  You could pass in an array of references to each of the LEDS.  (Or a reference to an array of LED's) that allows you to index to the reference that you want to turn on and off.

This would be a sub-VI you would put between your other VI's, you would control the flow by wiring the sub-VI's in series with error registers.
