function SCAN_Op times out but it's not consistent.

[skilagig]

I have a PXI 1000B chassis connected to a SCXI 1001 via a PXI6031E MIO card. I have 6 1102c modules plugged into the SCXI chassis. Each module is connected to a BNC 2095 (where my field inputs come in)I have it setup to mux 192 channels into one A/D. I wrote a small program in LabWindows to get familiar with setting up the scan list. The function SCAN_Op times out but not consistently. I have included my code. Can you suggest anything?
Thank you.

Hello;

The best way to start the development of your application is to take a look at the NI-DAQ shipping examples at C:\Program Files\National Instruments\NI-DAQ\examples\VisualC\SCXI.

I modeled my code after one of the sample programs. They use a Timeout_Config right before the SCAN_Op function and they disable it before the end of the program. I've tried to use it but I still get random timeout errors.
