While Loop Help

[Jerome1288]

I'm trying to simulate pump strokes and my while loops does not seem to be working. I have to stop the entire VI to update the value. I want the vi to continuously check my input value if that's possible.

I have attached my VI. I am also running 2010 LABView. Any suggestions on how to change my loop would be great!

Thank You

(You did not attach anything and it is LabVIEW, not LABView)

Make sure the terminals are inside the while loop.

Pump VI

[MrHappyAsthma]

I can't open your VI because I have LabVIEW 2009, but you might want to practice getting the spelling on "LabVIEW" down.  It is not "LABView". 

It stands for "Laboratory Virtual Instrument Engineering Workbench".  So that gives you an idea of where the capitalization comes from 😛

And good luck with your While Loop pumping.

You can use the DAQmx Write VI to change the values of your frequency and duty cycle.  I recommend using an Event Structure inside of your while loop and write on the Value Change of your controls.
