Weird behaviour with Simulate Signal and loops

[achb]

I'm having some weird behaviour with Simulate Signal and while loops. Attached is a picture of my program. The problem I am having is that when I use Stop to stop the inner while loop, then use Go to restart the inner loop, Simulate Signal will instantly generate a bunch of data points in between when I pressed Stop and Go. For example, if I stop 5 seconds in,wait 5 seconds,then press Go, it will instantly generate data for t=5 to t=10. What I need is for the signal generation to stop when I press stop, and continue where it left off when I press Go. How can I accomplish this? I have no idea why it's exhibiting the described behaviour in the first place.

Hi achb,

Would you provide a screen shot of the configuration window for the simulate signal express VI? I was able to reproduce the issue when I used "Simulate acquisition timing" under timing, but the VI behaved as you described you wanted it to when I used "Run as fast as possible". Have you tried that setting?

Even better than supply more screen shots is to supply no screen shots, but to attach your actual VI (save it first) instead.  This lets us "poke under the covers" and even execute your VI to see what it does.  [Don't worry -- almost all Forum beginners make this mistake ...]
