Trouble using Real Time "Wait" and "Wait until"

[Real-Time Measurement and Control]

Hi,

My problem is:
When I use Labview Realtime with a while loop in CompactRIO, if I use a "Wait" or "Wait Until" function with unit "us" ot "ns" the loop will stop there forever. However, if I set the unit to ms, the loop can normally run.

Besides, if I run the same vi under the host computer (not under CompactRIO), the loop can run correctly with whatever units "ms", "us", or "ns".

Can anyone help me to solve this problem or tell me why?

Thanks!
