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

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
