FANUC FOCAS is a set of dynamic link libraries (DLLs) that enable communication between a computer and a FANUC CNC Ethernet or PCMCIA interface. Core Capabilities
Instead of writing complex C data structures from scratch, you can use existing community wrappers: fanuc focas python
def collect_machine_data(handle, csv_filename="cnc_data.csv"): data_log = []
import pyfocas # CNC Connection Parameters ip = "192.168.1.10" port = 8193 handle = None try: # 1. Open Communication handle = pyfocas.focas_open(ip, port) print("Successfully connected to FOCAS.") # 2. Read Machine Status (Mode, Status, Alarm) status = pyfocas.cnc_statinfo(handle) print(f"Machine Mode: status['mode']") print(f"Machine Status: status['status']") # 3. Read Spindle Speed spindle_data = pyfocas.cnc_rdspdlth(handle) print(f"Actual Spindle Speed: spindle_data['speed'] RPM") except Exception as e: print(f"Error: e") finally: # 4. Close Connection if handle: pyfocas.focas_close(handle) print("FOCAS Connection Closed.") Use code with caution. Common FANUC FOCAS Functions in Python if ret == 0: status_map = 0: "Standby",
The FOCAS library grants access to nearly all internal CNC data via Ethernet or High-Speed Serial Bus (HSSB). 18;write_to_target_document7;default0;4c0;18;write_to_target_document1a;_rXjuaenGFY6UwbkPwOyrqA4_20;16; 0;52f;0;401;

The combination of FANUC FOCAS and Python opens up a wide range of possibilities for automation, data analysis, and custom application development. Here are some example applications:
