CompactRIO cRIO-9066/cRIO-9067 Operating Instructions
STATUS LED
The STATUS LED indicates several situations, as shown in Table 2.
USER1 LED
You can define the USER1 LED to meet the needs of your application. To define the LED, use
the RT LEDs VI in LabVIEW. Refer to the
LabVIEW Help
for more information about the
RT LEDs VI.
USER FPGA1 LED
You can use the USER FPGA1 LED to help debug your application or easily retrieve application
status. Use the LabVIEW FPGA Module and NI-RIO software to define the USER FPGA1 LED
to meet the needs of your application. Refer to the
LabVIEW Help
for information about
programming this LED.

Status LED Indications
Status
Indication
Off
The chassis is operating normally.
Blinks twice and
pauses, every few
seconds
The chassis
has detected an error in its software. This usually
occurs when an attempt to upgrade the software is interrupted.
Reinstall software on the chassis. Refer to the
Measurement &
Automation Explorer (MAX) Help
for information about installing
software on the chassis.
Blinks three times and
pauses, every few
seconds
The chassis is in safe mode. Refer to the
Measurement &
Automation Explorer (MAX) Help
for information about safe mode.
Blinks four times and
pauses, every few
seconds
The software has crashed twice without rebooting or cycling power
between crashes. This usually occurs when the chassis 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 blinks
The chassis has detected an unrecoverable error. Contact National
Instruments.
On for more than
five minutes
The chassis has detected an unrecoverable error. Contact National
Instruments.
On momentarily
The chassis is booting. No action required.
