Why Does My cRIO Controller Not Show Up in MAX?

Hardware: Compact FieldPoint>>Controllers

Problem:
Why doesn't my cRIO controller show up under Remote Systems in the Measurement and Automation Explorer (MAX)? 

Solution:
There can be several reasons why a cRIO controller does not show up under Remote Systems in MAX, most of them network-related. Here is a list of some of the most common troubleshooting steps to recognize your controller in MAX.
  • Make sure that you have the correct version of NI-RIO installed on the host PC.
    • Refer to related links section of this document for version compatibility information.
  • Check the status LED on the controller. 
    • Refer to your cRIO's operating instructions to determine what might be wrong with the system.
  • Switch the reset IP switch
    • This restores the controller to the default IP address (0.0.0.0). 
  • Check that the network cable is secure on the target and host computer. 
    • If you are connecting directly from the host computer to the cRIO controller, make sure that you have a crossover cable. 
    • If connecting through the local network, double check that you are using a standard network cable. 
  • If you have network firewalls enabled, try temporarily turning them off. 
    • Security software such as BlackICE can possibly block network communication to and from your cRIO controller.
  • Make sure that the host and target controller are on the same subnet. 
    • If the cRIO controller is on a different subnet, you'll need to manually add the target in MAX by right-clicking the Remote Systems menu, and selecting Create New.
  • If you are using an intelligent switch on the network, make sure that it is not disabling a port that is routed to the target.
    • Some intelligent switches that are used on a network will automatically disable some ports that could be blocking communication to the target from the host.
  • If you have multiple network adapters (ie wireless), be sure that all other network cards are disabled.
    • When computers have multiple network cards, MAX may choose to look for remote devices from the card that your cRIO is not connected up to.
    • If one card is wireless, be sure to disable it from the control panel, not just turn off the wireless antenna.
