USER1 LED
The USER1 LED is a bi-color green/yellow 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. For more information about the RT LEDs
VI, refer to the LabVIEW Help.
Resetting the Network Configuration of the Controller
If the controller cannot communicate with the network, you can use the
IP RESET switch to manually restore the controller to the default network
settings. When you reboot the controller with the IP RESET switch in the
ON position, the controller attempts to connect to the network using
DHCP. If the controller is unable to initiate a DHCP connection, it connects
to the network with a link-local IP address with the form
169.254.x.x.

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.
