Timing

[JoeyBeagen]

I have a simple problem, but I am unclear on how to do this in labview.  I am doing a cycle test for valves and we need to time the closing cycle. I  have Labview set up so the open command and the stop command are on Binary signal. For instants, the valves begins to close labview reads a 1.. The valves is closed labview equals 0.

I need a way to calculate and show the time is take to close on labview.( the duration between 1 and 0)  I have been playing around with some case structures and while loops with the clock, but I can't seem to get a something that labview likes.

Any Suggestions?

How long is the average time between the 0 and the 1?

See if the attached will work for you. Inside the WHILE loop  you would keep reading the valve value.

When it is "1", stop the WHILE loop.

The Time is about ten Seconds..... and we are doing 20,000 cycles

How do you stop the while loop when the value is 1?  I tired using a True/False, but that doesn't work that same as the stop button so the timing loop always outputs the number 0 ?

I'm not sure I understand your question.

Would it be possible for you to upload the VI?
