Quickly connect to Fanuc CNCs using FOCAS and Python to read/write data, monitor status, and automate tasks. Example libs: python-focas or pyfocas; use ctypes to call FOCAS2 DLL (or eWON/OPC for networked setups). Always run on a secure, authorized network and test on non-production machines.
| Use Case | FOCAS Function Area | Python Outcome |
|----------|---------------------|----------------|
| OEE Dashboards | cnc_rddynamic, cnc_rdoption, rdopn | Real-time % utilization, idle time detection |
| Predictive Maintenance | cnc_rdaxisdata (servo load, torque) | Trend analysis to predict bearing/tool wear |
| Program Management | cnc_upload, cnc_download | Automatic backup of all CNC part programs |
| Alarm Monitoring | cnc_rdalarmmsg | Push alerts to Slack, Telegram, or email |
| Energy Monitoring | cnc_rdpower (on supported models) | Track energy per part produced | fanuc focas python
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.
