Solid: Fault condition detected. One or more user voltage rails are in short-circuit or overcurrent condition
Blinking: The input voltage is too high (greater than 16 V) and all outputs, including the RSL output, are disabled.
Solid: These are generally caused by metal shavings falling inside the case. You can clear this by trying any of the following steps:
Blinking: The power supply is incorrect. Check your roboRIO power connection. For the FIRST Robotics Competition (FRC) it should be wired to the dedicated output in the Power Distribution Panel (PDP). Follow this guide for connection guidance: Wiring the FRC Control System
Solid: No code. The protocol indicates that no user code has been loaded.
Blinking: E-Stop. The protocol indicates that the driver station has E-Stopped the robot.
Solid: Deploy your code again. If using LabVIEW, make sure you select Run as Startup when deploying code for competition use. Refer to the next document for more information: Creating, Building and Loading your Benchtop Test Program
Note: LabVIEW code can take up to 1 minute to show up (turn the Comm LED green) after booting up.
Blinking: Reset the roboRIO by clicking the Reset button or doing a power cycle.
Outputs unknown, undetermined, or in test mode.
The Drivers Station has started a Test Match on the roboRIO. Disable the roboRIO in the Driver Station and the light should clear.
