FANUC FOCAS is a set of dynamic link libraries (DLLs) provided by FANUC. It allows external software to interact directly with the CNC controller via Ethernet (TCP/IP) or HSSB (High-Speed Serial Bus). Through FOCAS, you can read and write: Operating mode, alarms, execution status. try: with FocasController(cnc_ip) as cnc: logging
You can easily pipe CNC data directly into Python’s powerful data analysis libraries (like Pandas or NumPy) or visualization tools.
However, the rise of Python in the industrial IoT (IIoT) space has changed this completely. Python bridges the gap between the factory floor and powerful data analytics, enabling engineers to build flexible and cost-effective monitoring systems.
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 It allows external software to interact directly with
pyfanuc is a free, open-source library available on PyPI. It is designed to be a clean, modern Python interface to a FANUC controller. It abstracts away much of the complexity of the underlying FOCAS calls, allowing you to connect and read data in just a few lines of code.
FANUC FOCAS is an open architecture and communication interface developed by FANUC, allowing users to access and control FANUC devices, such as CNC machines, robots, and servo drives, using a variety of programming languages. FOCAS provides a set of APIs (Application Programming Interfaces) that enable developers to read and write data, execute commands, and monitor the status of FANUC devices. This interface is designed to facilitate the integration of FANUC devices with external systems, such as MES (Manufacturing Execution Systems), ERP (Enterprise Resource Planning) systems, and custom applications.
