FANUC CNC controls
PLCGateway monitors FANUC CNC machines over FOCAS Ethernet, without Fwlib or a Windows PC, and turns their data into OEE, alarms and dashboards.
PLCGateway reads FANUC CNC controls with its own implementation of the FOCAS Ethernet protocol: machine status, positions, spindle speed and load, feed, alarms, programs, macro variables, parameters, diagnosis and PMC signals.
Because no FANUC library is needed, PLCGateway runs on Windows, Linux or a small ARM device at the machine. With the production model it calculates availability, cycle counts and OEE for every CNC, and the OPC UA server shares the data with MES.

Notes for commissioning
- Enable FOCAS on the embedded Ethernet port in the control's Ethernet settings (port 8193).
- Use status.run and the program number for availability and cycle detection in the production model.
- Only macro variables are writable; everything else is read only.
- Let an AI assistant create a standard tag set for each CNC over MCP.
Questions and answers
Does PLCGateway need FANUC Fwlib32?
No, the FOCAS Ethernet protocol is implemented natively, so it runs without Windows and without FANUC DLLs.
Can it read FANUC robots?
The FOCAS driver is for CNC controls. Robot controllers can be connected through OPC UA or Modbus TCP if the robot offers them.
How many machines can one installation monitor?
Each machine is a device with its own connection; a single PLCGateway typically monitors a whole shop floor.
