Description

The robot EtherNet/IP Adapter was not able to initialize.

Remedy

This alarm generally implies that the Ethernet or TCP/IP interface is not set up correctly. For example, if no IP address is defined, then EtherNet/IP cannot initialize. Verify network connectivity using the ping utility (on the robot and also on the local PC). If the problem persists, document the events that led to the alarm, and call your FANUC or FANUC Robotics technical representative.
