Issue Details

I am using the CompactRIO (cRIO) 9040. What rates can I acquire from my modules at?

Solution

There are a few considerations when using DAQmx with the CompactRIO-904X:
 
  • The acquisition sample rate is limited by the Sampling Rate specification for your specific C Series Module. You would use the DAQmx Timing VI to configure your samples rates. Data is streamed to the buffer on your cRIO's Real-Time Operating System, and pulled off of the buffer with the DAQmx Read function. Consult this article for more information on timing and buffers.
  • Specifically for Hardware Timed Single Point acquisition (continuous streaming without a buffer), the update rate is 5 kHz, per the specification on this White Paper
