Fanuc Focas 2
Practical implementation with C#/Python wrappers.
is the standard for modern Ethernet-capable controls, including the 30i, 31i, 32i, and 0i-F/0i-MF families. Core Technical Architecture fanuc focas 2
| Function Call | Purpose | | :--- | :--- | | cnc_allclibhndl3 | Establishes the connection to the CNC. | | cnc_rdaxisdata | Reads current axis data (position, load, feedrate). | | cnc_rdspeed | Reads spindle speed and load. | | cnc_rdstatus | Reads the machine status (Running/Alarm/Idle). | | cnc_rdalarm | Reads active CNC alarms. | | cnc_rdmacror | Reads Macro variables. | | cnc_wrmacrow | Writes to Macro variables (used for dynamic work offsets). | | cnc_upload | Uploads a program from the CNC to the PC. | | cnc_download | Sends a program from the PC to the CNC. | Practical implementation with C#/Python wrappers
For those in the Siemens ecosystem, the MindSphere documentation outlines how to use the FOCAS protocol to bridge CNC data to the cloud. | | cnc_rdaxisdata | Reads current axis data
If you are setting up a new data collection system today, you will almost exclusively use FOCAS 2. Most modern Fanuc controllers ship with FOCAS 2 functionality embedded in the firmware, though specific options may need to be purchased.
