# Execute a program on the FANUC device dev.execute_program('my_program')

# Using ctypes approach to demonstrate how to check CNC mode # The mode indicates whether machine is in Auto, MDI, JOG, etc.

def get_cnc_mode(handle): # ODBMODE structure for mode data class ODBMODE(ctypes.Structure): fields = [ ("mode", ctypes.c_short), # Operation mode ("i_mode", ctypes.c_short), # Input mode ("info", ctypes.c_short * 4), # Additional info ]

The following architecture demonstrates how to load the FOCAS library, establish a TCP/IP connection to a CNC machine, and read the absolute position of the X-axis using Python's native ctypes library. 1. Initializing and Connecting

# Set up the connection parameters machine_ip = "192.168.1.100" machine_port = 8080

Once connected, you can call specific FOCAS functions by passing the machine handle . Let's look at how to pull two of the most requested data points: Machine Status and Axis Positions. 1. Reading Machine Status ( cnc_statinfo ) fanuc focas python

If you are just starting, recommend using the pyfanuc library to get familiar with protocol analysis.

Python libraries like pyfanuc and chattertools have effectively removed the traditional technical barriers. By understanding the core protocols and following the practical examples in this guide, you can begin your journey to unlock the full potential of your FANUC manufacturing assets today.

The open-source library pyfanuc (available via pip install pyfanuc ) wraps the native FOCAS DLLs using ctypes . It provides a Pythonic interface. # Execute a program on the FANUC device dev

Reads I/O signals, allowing monitoring of PLC inputs/outputs. Advanced: Program Management with FOCAS

Ensure you have Python set up on your machine.

John had heard about FANUC's FOCAS (FANUC Open CNC API) library, which allowed developers to create custom applications to control FANUC CNC machines. He decided to use Python, a language he was familiar with, to create a program that could communicate with the CNC machine using FOCAS. Initializing and Connecting # Set up the connection

Ensure your PC can ping the CNC machine's IP address. FANUC FOCAS typically uses TCP port 8193 .
