Fanuc Focas: Python

(FANUC Open CNC Application Server) is a library that exposes the internal data points of a FANUC CNC—spindle load, axis positions, alarms, program execution status—via a network or serial connection. And when you combine FOCAS with Python , you unlock real-time monitoring, predictive maintenance, automated data logging, and even remote control of industrial machinery using one of the world's most accessible programming languages.

Each function returns an error code (0 = success). Always check return values. Combine the live reading loop with a web framework. Example with Streamlit :
