Troubleshooting Network Communication for LabVIEW Real-Time Systems

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 obtain an IP address, it connects to the network with a link-local IP address with the form 169.254.x.x.

Complete the following steps to restore the controller to the default network settings.
  1. Move the IP RESET switch to the ON position.
  2. Push the RESET button to cycle power to the chassis.
  3. Configure the IP and other network settings in MAX from the host computer.
  4. Move the IP RESET switch to the OFF position.
