The handle is an integer ID used for all subsequent calls. Once connected, you can poll any data point. Let’s read the current position (absolute, machine coordinate) and spindle load : fanuc focas python

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.
