Hello, 
I am trying to have a PID control with USB 6211 to give duty cycle according to the feedback getting from the USB 2408-2AO reading. But when I connect the mccdaq to process variable of PID control I am getting an error. Can anyone tell me how to resolve this issue.
Thanks.

Besides, you should not place everything inside the while loop but only the Read and Write API. You can Change Duty Cycle on a Continuous Pulse Train
