Issue Details

I am using the RT LEDs VI to light the USER1 LED on my CompactRIO controller. According to LabVIEW Real-Time Module Help: RT LEDs VI, state 2 sets the LED to the device default color 2 (if available). What controllers support default color 2?
 

Solution

Currently, the controllers that have a secondary LED color are the NI 902x, NI 903x, NI 904x, and NI 908x CompactRIO controllers. All CompactRIO controllers have a green default color. The NI 902x, NI 903x, 904x, and NI 908x controllers also have yellow secondary color.  

There is no state that will automatically toggle between off and the secondary color, so you must manually program switching between state 0 and state 2 to make the light blink.
