The cRIO-905x is Not Communicating with the Network

Version:
    Last Modified: August 30, 2018

    Use this topic to troubleshoot possible reasons your cRIO-905x is not communicating with the network.

    • Ensure that the USB Device connection between the cRIO-905x and the host computer and the Ethernet connections between the host computer and the router are secure.
    • Configure the IP and other network settings by completing the following steps.
      1. Use a USB-Type-C-to-USB-Type-A cable (included in the kit) to connect the cRIO-905x USB Type-C Device Port with Console Out to a host computer. The USB driver creates a virtual network interface card and assigns an IP address to the cRIO-905x in the format of 172.22.11.x.
      2. In MAX, expand your system under Remote Systems.

        If you do not see the cRIO-905x under Remote Systems, use the Troubleshoot Remote System Discovery utility to walk through troubleshooting steps.

      3. Select the Network Settings tab to configure the IP and other network settings.
      4. (Optional) Use the RJ-45 Ethernet port 0 or port 1 to reconnect the cRIO-905x to the host computer. The cRIO-905x attempts to initiate a DHCP network connection at power up.

        Note  

        If the cRIO-905x 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-905x over a standard Ethernet connection.

    • Ensure that you have the correct version of NI CompactRIO Device Drivers installed on the host computer. Visit ni.com/info and enter the Info Code swsupport for the minimum supported versions of LabVIEW and NI CompactRIO Device Drivers.

      If you have recently upgraded LabVIEW, you must reinstall NI CompactRIO Device Drivers.

    • Ensure that the NI USBLAN adapter is recognized in the Device Manager. Select Start»Control Panel»Device Manager»Network adapters»National Instruments»USBLAN adapter. If the USBLAN adapter is not recognized, you must reinstall NI CompactRIO Device Drivers.

      For Windows 10, you may need to search for the Control Panel as it not always available from the Start Menu.

    • Temporarily disable any network firewalls or other security software.
