cRIO-9012/9014 Operating Instructions and Specifications
This LED is a bi-color LED. When the controller is powered from V1,
the POWER LED is lit green. When the controller is powered from V2,
the POWER LED is lit yellow.
FPGA LED
You can use the FPGA LED to help debug your application or easily
retrieve application status. Use the LabVIEW FPGA Module and
NI-RIO 2.0 or later to define the FPGA LED to meet the needs of your
application. Refer to
LabVIEW Help
for information about programming
this LED.
STATUS LED
The STATUS LED is off during normal operation. The controller
indicates
specific error conditions by flashing the STATUS LED a certain number of
times every few seconds, as shown in Table 2.
Table 2.

Indication
1
The controller is unconfigured. Use MAX to configure the controller.
Refer to the
Measurement & Automation Explorer Help
for information
about configuring the controller.
2
The controller
has detected an error in its software. This usually occurs
when an attempt to upgrade the software is interrupted. Reinstall
software on the controller. Refer to the
Measurement & Automation
Explorer Help
for information about installing software on the
controller.
3
The controller is in safe mode because the Safe Mode DIP switch is in
the ON position. Refer to the
Configuring DIP Switches
section for
information about the Safe Mode DIP switch.
4
The controller 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 controller memory usage.
Modify the VI as necessary to solve the memory usage issue.
Continuous flashing
or solid
The controller has detected an unrecoverable error. Please contact
National Instruments.
