LED Details

You can set either ON or OFF state for the LEDs.

The roboRIO contains the RADIO, COMM, and MODE LEDs. Every LED associates with two Boolean controls for displaying various colors. For example, the RADIO LED associates with the RADIO (Green) control and the RADIO (Red) control. The following table shows the configuration options to display a green, red, or orange RADIO LED:

Green Red Orange Off
RADIO (Green) TRUE FALSE TRUE FALSE
RADIO (Red) FALSE TRUE TRUE FALSE
Note   For any application that uses one or more Express VIs, you must use the Reset VI at the end of the application to reset the FPGA target and all the I/O channels. Otherwise, the Express VIs might not execute correctly when you run the application for the second time.
