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.

Each function returns an error code (0 = success). Always check return values. Combine the live reading loop with a web framework. Example with Streamlit : import focas2 handle = focas2
time.sleep(1) finally: focas2.cnc_freelibhndl(h) monitor_cnc("192.168.1.100")
# Get spindle load (percentage) spindle = focas2.cnc_rdspindle(h, 0) # 0 = first spindle print(f"Spindle load: spindle['data'][0]['load']%") # Start a stored program (O1234) focas2
