Every FOCAS session begins by allocating a handle using cnc_allclibhndl3 . This handle tells FOCAS which specific machine you want to talk to during subsequent function calls. fanuc focas python

# First, install the library: pip install pyfanuc from pyfanuc import FocasController # 1. Connect to the CNC cnc = FocasController('192.168.1.100', port=8193) # 2. Read All Axis Data (Position, Speed, Load) # Reference: https://www.inventcom.net/fanuc-focas-library/position/cnc_rdaxisdata try: axis_data = cnc.read_axis() for axis, data in axis_data.items(): print(f"Axis axis: data['position'] mm, Load: data['load']%") except Exception as e: print(f"Error connecting to CNC: e") # 3. Read a User Macro Variable (#100) # Reference: https://www.inventcom.net/fanuc-focas-library/ncdata/cnc_rdmacror2 try: macro_value = cnc.read_macro(100) print(f"Macro #100: macro_value") except Exception as e: print(f"Error reading macro: e") # 4. Read Alarms try: # Read currently active alarms alarms = cnc.read_alarms() print(f"Active Alarms: alarms") except Exception as e: print(f"Error reading alarms: e") Use code with caution. Common Use Cases 1. Real-time Machine Monitoring

Here's an example PyFOCAS code snippet:

pip install pyfocas

focas = ch.Focas(ip='192.168.1.100')

pos = ODBAXIS() ret = focas.cnc_absolute2(handle, -1, 4, ctypes.byref(pos))

try: with FocasController(cnc_ip) as cnc: logging.info(f"Starting data collection loop, logging to csv_filename every monitoring_interval_seconds seconds.") : Modern manufacturing relies on real-time data to

cnc.close()

def read_with_retry(func, max_retries=3, delay=1): for attempt in range(max_retries): ret = func() if ret == 0: return ret time.sleep(delay) return ret

For detailed information about axis data parameters, refer to the official FOCAS documentation on cnc_rdaxisdata . This handle tells FOCAS which specific machine you
