refresh rate of the daq-pad 6016

Laurent,

Have you tried using one of the sample vis to test your continuous input? Please try sampling at 1kHz and acquiring 100 samples per channel.

If you are trying to do some analog output to control the system I would recommend having the analog output run in parallel with the analog input and immediately write the calculated output as soon as it is read. This works better because you will not be stopping and restarting the task (as is the case with the DAQ Assistant, hence the delay).

This Developer Zone article outlines how you can perform PID control only it uses a Counter output instead. I would use this VI as a base to start working on your code. I would also start by changing the counter output to your Analog output and change the PID code to your Proportional control code.
