Time loop problem when add a parellel subvi in another time loop

Question

I have four time loops in parellel, they work find
without any problem. However when I add a third party
Vi as a subvi in parellel inside a another time loop.
The first four time loops start working eraticly.
Is there any way I can make them work independently
time wise. There is no data transfering between any
of the loops

Answer 1

Hello
The VI with the timing loop is set to cycle once every second, and all it does
Is turn on a boolean light indicator off and on every second. It has a boolean
inverter connected to the shift registers of the loop. Its priority is set to Normal.
The third party VI interacts with a spectrometer hardware. The spectrometer measures
The amount of light and transform the data collected by the spectrometer into digital information, which is then passes to LabView. LabView then compares the sample information to a reference measurement and displays the processed spectral information.
The timing loops of the main VI is manually set by me the user.
The timing loops would loose its sequence; the loops would run normal for a couple
Of cycle the
n either run fast or run slow. If I take out the third party subvi everything
Runs fine
I am using windows XP with LabView 7.1
