Issue Details

I am using a 9214 module with my CompactRIO in FPGA interface mode. The 9214 is rated for 68 Hz but it is slowing my loop rate and it only updates once a second.

Solution

The 9214 module has two modes: High Resolution and High Speed. The high resolution mode is limited to 0.96 Hz, hence the slowed down loop rate. Try changing the mode to High-speed.

To do that, right-click on your module in the LabVIEW project, and go to the properties. Then, modify the setting according to this picture:
