Two While Loops on one Block diagram do not run independently. I have two millisec timers with different values controlling LED's, but the LED's blink in phase. Why?

If I put the While Loops on two separate VI's and run them both, I get the expected result; ie, the LED's blink asynchronously.

Do you have any wires connecting both loops within the VI?

Maybe try posting an example?

No - just two While loops on the same blk diag page.

OK, this is my first time to use the forum, and I see that I can post a file attachment, which I will do now.

Thank you _very_ much for your prompt assistance!

If you are using the "Continous Run" button the LEDs will blink synchronously because the VI doesn't run again until both wait times have expired.

In your VI, I changed the while loop conditionals to "Continue If True" and the LEDs blink at different rates.

I changed the VI per your comment, and it works 'as expected' now...

Kudos & thanks to VI Guy!
