Troubleshooting Network Issues

cRIO-9047 is Not Communicating with the Network

  • Ensure that the Ethernet connections between the cRIO-9047 and the host computer, and between the host computer and the router are secure.
  • Configure the IP and other network settings by completing the following steps.
    1. Use the USB-to-Type-A cable (included in the Battery Test System kit) to connect the cRIO-9047 USB device port to a host computer. The USB driver creates a virtual network interface card and assigns an IP address to the cRIO-9047 in the format of 172.22.11.x.
    2. In Measurement & Automation Explorer (MAX), expand your system under Remote Systems.
      Note If you do not see the cRIO-9047 under Remote Systems, right-click Remote Systems, and select Troubleshoot Remote System Discovery to walk through troubleshooting steps.
    3. Select the Network Settings tab to configure the IP and other network settings.
    4. (Optional) Use the standard measurement rack Ethernet port to reconnect the cRIO-9047 to the host computer. The cRIO-9047 attempts to initiate a DHCP network connection at power up.
      Note If the cRIO-9047 cannot obtain an IP address, it connects to the network with a link-local IP address with the form 169.254.x.x. The host computer communicates with the cRIO-9047 over a standard Ethernet connection.
  • Temporarily disable any network firewalls or other security software.

Verify the cRIO-9047 controller IP configuration by completing the following steps:

  1. Put the cRIO-9047 in safe mode and enable the RS-232 serial port by holding down the RESET button on the controller front panel for 5 seconds.

    The STATUS LED starts blinking three times every few seconds. Refer to the cRIO-904x User Manual for more information about safe mode.

  2. Connect a monitor to the mini DisplayPort to view the IP address.
    Note The controller also broadcasts the IP address through the RS-232 serial port. Refer to the cRIO-904x User Manual for more information about serial port configuration on the cRIO-9047 controller.
  3. Set a new DHCP connection by holding the RESET button on the controller front panel down for 5 seconds. The STATUS LED repeats the same behavior from Step 1.

    If the cRIO-9047 fails to set a new DHCP address, it assigns itself a link-local IP address. If the DHCP connection is successful and appropriate for your application, skip to Step 6.

  4. In MAX, expand your system under Remote Systems.
  5. Select the Network Settings tab to configure the IP and other network settings.
  6. Reboot the cRIO-9047 by pressing the RESET button on the controller front panel.

cDAQ-9189 Chassis Disconnects from Network

If your cDAQ-9189 chassis becomes disconnected from the network, try the following solutions:

  • After moving the chassis to a new network, NI-DAQmx may lose connection to the chassis. In this case, click Reconnect to provide NI-DAQmx with the new hostname or IP address.
  • The cDAQ chassis icon indicates whether it is recognized and present on the network. If a connected chassis appears as disconnected in the configuration tree in MAX, select Self-Test or Reset Chassis. If successful, the chassis icon changes to blue/grey.

For additional troubleshooting resources for the cDAQ-9189 chassis, refer to Finding a Network DAQ Device in MAX in the Measurement & Automation Explorer Help for NI-DAQmx.
