PXI 6120 Real time bug

Recommended Posts

Does anyone have experience using the PXI 6120 DAQ card with LV real time?

I have been plagued by problems for over a year. (Using Traditional Daq)

I use the analog output for continuously generating a sine wave. Then I set up the analog input to capture fininte data for a set number of hardware triggers. 10% of the time, when the analog input re-arms for the next trigger, the analog output stops updating. No error code is ever created by the sofware driver. The short term fix has been to monitor the analog output with a portable scope and reboot the PXI to reset the hardware.

The NI support network came up with the solution of using "DAQmx" a major code rewrite.

I finally rewrote the code only to find a new set of "buggy boos". These new hurdles are the result of using LV8.

To get over the new hurdles, I am hoping that a good example program exists for LV8 RT that shows how to remotely control a PXI chassis with 3 DAQ cards. :lightbulb:
