Problems with timers

[trap]

I'm using Wait Until Next ms Multiple VI in my program and all is OK. Except when I use two of this VI's simultaneously. Then the times becames irregular. (The periods are long enough, so this isn´t the problem.) Does anybody know why? Thanks in advance.

What are the errors you are seeing? I ran a loop with a 100 ms and 200 ms Wait Until Next ms Multiple VIs and it ran correctly at abou 200 ms each time. What kind of behavior did you see?

I've just solved this problem. I was having problems because I didn´t know that in the fist cicle of the loop this VI doesn't keep the time. My loops had one or two cicles. Thanks.
