代碼 HOST-281: SMB: Time-out waiting for PC
問題描述與安全警告
Fanuc R-30i Series Robot Controller 觸發了嚴重的 SMB: Time-out waiting for PC 警報。需要由合格的操作員或維修技師立即處理，以防止在製造週期中對設備造成二次損壞或導致零件報廢。在接觸電氣控制箱之前，請務必確保遵循標準安全和停機掛牌 (LOTO) 程序。
官方故障排除步驟
Cause: The robot timed-out while waiting for the PC to respond to a PC Share request. Remedy: Verify the PC is properly connected to the network, and can be pinged on the network. Verify the PC Share client tag is properly configured, and the PC has properly shared the location/directory being accessed. The default timeout value can be changed in System Variables. If the PC is too slow for the default timeout, set a more reasonable timeout value in seconds in $SMB_CLNT[X].$RSPTMOUT, and power-cycle the controller. If the problem persists, document the events that led to the error, and call your local FANUC representative.
