I have a VI written that reads in data from a pitot tube/anemometer in the wind tunnel. After setting a speed I want to be able to read 50 milliseconds of data from the Pitot Tube, put this data in an array along with the desired speed, and input these into a PID algorithm which regulates the output of a voltage controlling the speed of the Wind Tunnel. I tried using Timed Loops to no avail, and using the Elapsed TIme VI to set off a case structure outside of the loop however this only worked the first time the Elapsed Time output was True. Any Ideas?
(The VI is on a computer not connected to the network currently)

Hi all,
I'm trying to communicate with an instrument that uses serial connection. I have a closed loop wind tunnel algorithm in place that uses a pitot-static system in the wind tunnel to close the control loop (A voltage out controls speed).
I am calibrating various anemometers, and previously was using a device that outputted a voltage and was read with a USB DAQ device. I was able to have my control loop run extremely fast prior to using the serial device. Any thoughts on this?
