Color LED State Indication
POWER Green Solid The cRIO controller is powered from the V1 input
Yellow Solid The cRIO controller is powered from the V2 input
— Off The controller is not powered.
STATUS Yellow 2 flashes
every few
seconds
There is no software installed, which is the out-of-box state,
or the controller has detected an error in its software.
An error can occur when an attempt to upgrade the software
is interrupted. Refer to the MAX Help for information about
safe mode.
3 flashes
every few
seconds
The controller is in safe mode. Refer to the MAX Help for
information about safe mode.
4 flashes
every few
seconds
The software has crashed twice without rebooting or cycling
power between crashes. This usually occurs when the
controller runs out of memory. Review your RT VI and
check the memory usage. Modify the VI as necessary to
solve the memory usage issue.
Continuously
flashing
The controller has not booted into NI Linux Real-Time. The
controller either booted into an unsupported operating
system, was interrupted during the boot process, or detected
an unrecoverable software error.
Solid The controller is booting up.
Red Continuously
flashing
An internal power supply has failed. Check front-panel I/O
and C Series module connections for shorts. Remove any
shorts and power cycle the controller. If the problem
persists, contact National Instruments.
— Off Normal operation.
USER1 Green/
yellow
— You can define the USER1 LED to meet the needs of your
application.
To define the USER LED in LabVIEW Real-Time, use the
RT LEDs VI. For more information about the RT LEDs VI,
refer to the LabVIEW Help.
USER
FPGA1
— Use the LabVIEW FPGA Module and NI-RIO software to
define this LED to meet the needs of your application. You
can use the USER FPGA1 LED to help debug your
application or retrieve application status. Refer to the
LabVIEW Help for information about programming this
LED.
