Issue Details

I have a C Series XNET device in my CompactRIO chassis which is reporting that it needs a firmware update. However, the device does not show up properly in NI MAX and therefore I can't access the option to perform an upgrade. It also might not show up at all in a LabVIEW project, when another C Series XNET module does. How can I upgrade the firmware for the device?


The C Series XNET modules require a specific configuration to be deployed to the FPGA in order for the cRIO and MAX to access it. The steps to generate and deploy this configuration can be found in the Getting Started with CompactRIO section of the XNET manual.
  1. Ensure all of the proper software is installed.
    1. On the host computer:  LabVIEW, LabVIEW Real-Time, LabVIEW FPGA, NI-RIO, NI-XNET
    2. On the cRIO: NI-XNET
  2. Add modules to the project.
    1. Add the controller to the project and select LabVIEW FPGA Interface as the chassis mode when prompted.    
    2. Add NI-XNET modules by right-clicking the chassis item (not the FPGA) and selecting New»C Series Modules»Existing target or device; then select your XNET device(s).
      1. If you cannot see your XNET device in this window, add it using the New target or device » C-Series Module, and then select your XNET modules.
  3. Compile and run an FPGA VI. An empty FPGA VI may be used; an existing VI will need to be recompiled to incorporate NI-XNET support for the configured slots.
  4. Once the configuration file is deployed, the XNET module will appear in MAX under the cRIO. Click the module and select Update Firmware.  This will open an Update Firmware window. Select Begin Update. Wait for MAX to indicate a successful update.
