I use cDAQ 9184 class with a NI-9411 to measure Speed and Torque frequency signal, i create a asynchronous custom device to meet my application, and there is a while loop in RT VI with 50ms wait, i deploy it to windows environment, it works, but the controller actual target loop rate become 25Hz, not what i set 100Hz, even i increase my controller target rate , it doesn.t help , so i wonder why, have someone met this situation before? i will post pictures tomorrow.
