Fanuc — Focas Python

(example):

try: while True: # Get absolute position (X, Y, Z, etc.) pos_data = focas2.cnc_rdposition(h, 0) # 0 = absolute print(f"X: pos_data['data'][0]:.3f Y: pos_data['data'][1]:.3f Z: pos_data['data'][2]:.3f") fanuc focas python

In the world of industrial manufacturing, FANUC CNC (Computer Numerical Control) machines are the gold standard—powering everything from automotive assembly lines to aerospace component machining. For decades, extracting data from these controllers or sending commands to them meant relying on proprietary, vendor-specific software (often written in C++ or ladder logic). That barrier has now fallen. (example): try: while True: # Get absolute position

The handle is an integer ID used for all subsequent calls. Once connected, you can poll any data point. Let’s read the current position (absolute, machine coordinate) and spindle load : The handle is an integer ID used for all subsequent calls

time.sleep(1) finally: focas2.cnc_freelibhndl(h) monitor_cnc("192.168.1.100")

import streamlit as st import focas2 import time st.title("FANUC CNC Monitor")

Place the DLL in a location Python can find (e.g., C:\Windows\System32 or your project folder). Every FANUC CNC with Ethernet needs an IP address and port (usually 8193 by default for FOCAS). You also need to enable the FOCAS server function on the CNC side (often a parameter change: e.g., set parameter 148 bit 0 = 1).
