Issue Description & Safety Warning
The Fanuc R-30i Series Robot Controller has triggered a critical EtherNet/IP Cannot Resolve Name alarm. Immediate attention from a qualified operator or maintenance technician is required to prevent secondary damage to the equipment or spoiled parts during the manufacturing cycle. Always ensure standard safety and LOTO procedures are followed before accessing electrical cabinets.
Official Troubleshooting Steps
Cause: The robot EtherNet/IP scanner could not resolve the configured remote adapter hostname. Remedy: Verify the Name/IP Address entered in the Scanner Configuration Screen is valid. Try to ping the address from the main EtherNet/IP screen. If using DNS, verify that DNS is properly configured. If using the robot Host Name tables (LOCAL and/or SHARED), verify the tables are properly configured. Press RESET to restart the robot scanner connection.
