Problem: I receive Error 56 in Measurement and Automation Explorer (MAX) when I try communicating with my Real-Time controller. My controller is connected with a cross-over cable. The error occurs in one or more of the following situations:
Solution: This error is typically caused by specifying a gateway IP address for the controller when one does not exist. Change the gateway IP address on the real-time controller to 0.0.0.0 or leave it blank, as seen below.  Click on the Apply button followed by the Reboot button to put the changes into effect. The gateway is used to route packets to outside networks. A typical Windows machine does not function as a gateway and causes the real-time controller to time out when it does not respond to the Real-Time controller's requests for a gateway.
