Code PRIO-286: FL-net Wait Frame Status
Issue Description & Safety Warning
The Fanuc R-30i Series Robot Controller has triggered a critical FL-net Wait Frame Status 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: My node is in the frame reception wait state because there are no other nodes in the network or my node can recognize any other nodes. Remedy: To start communication, add another node to the network. If my node does not recognize the other node, check whether the robot and remote communication devices are connected to the network properly and are configured correctly.
