Timing of three different PWM trains

[troop316twins]

Hello all,

I am trying to time three different software timed pwm trains so that two begin immediately after the first pulse stops.  Right now they all work sequentially.

Thanks so much for your help.

You need to make your subVI reentrant.  Go to its VI properties, execution tab, and choose the preallocated clone reentrant radio button.

Each time the subVI executes, it blocks execution of itself in the other loops, since it is not currently reentrant.  This leads to the serial behavior you are seeing.
