Here’s a structured review of (Factory Automation Network Connection) with a practical example, covering what it is, how it works, and a typical use case. What is FANUC FOCAS? FOCAS is a set of library functions and protocols that allow external applications (PCs, HMIs, MES, ERP) to communicate directly with FANUC CNC controllers (Series 0i, 30i, 31i, 35i, etc.) over Ethernet.

// Connect to CNC (IP, port 8193 default) ret = Focas1.cnc_allclibhndl3("192.168.1.100", 8193, 10, out handle); if (ret == Focas1.EW_OK) Console.WriteLine("Connected"); Focas1.ODBPOS posData; ret = Focas1.cnc_rdposition(handle, Focas1.ODBPOS_ABSOLUTE, out posData); if (ret == Focas1.EW_OK)

Console.WriteLine($"X: posData.data[0]"); Console.WriteLine($"Y: posData.data[1]"); Console.WriteLine($"Z: posData.data[2]");
