Hello,
I have a program that outputs TTL pulses using Counter Outputs with DAQmx to time equipment signals. We use the program to scan timing delays from a master oscillator. Occasionally we run into an issue where Labview will write the correct timing using DAQmx, but the signal on the card (PCI-6602) will not update to the new timing delay (measured using an oscilloscope). A temporary workaround we found is to restart Labview. This has become more frequent over time and I was wondering if I could receive input towards how to troubleshoot the problem more.
We are currently using Labview 2009, and we have noticed that the CPU usage of Labview is abnormally high during this time (up to 50%). This only seems to occur when the timing delays don't update properly, otherwise CPU usage is low (<5%).
Thanks
