Hi Ni Experts,
I am having trouble deciding which NI module suits me better. I am trying to do data acquisition temperature, pressure, and valve. In addition to that I need to implement PID controls (for example, valve will respond to pressure setpoint).
I seem some examples where people have used NI-9220, 9201, USB-6216 to do this because they have the "control" capability where as the USB-6003 for example, does not.
Could anyone provide some advice/comment on the NI-9xxx series or the USB-6xxx series as to which one I should go with?
