I am using a cDAQ to control my test stand. My main loop reads the analog and digital inputs. The loop timing is ~10ms. The pressure transducers are not connected so they are noisy, and because of that I can see that the indicators are being updated very rapidly. The problem I am having is when I activate one of the digital inputs there is a 5-10 second delay before the indicator updates. I can see that the LED on the cDAQ responds instantly. What could be causing this delay?
