CNC controller for a cutting machine

The paper addresses the field of factory automation within the scope of flexible production systems. The controller has been built on the open QNX real-time operating system for PC architecture. The commonly accepted graphical user interface environment of Microsoft Windows serves as the front-end of the HMI. The controller and the HMI are interconnected by the Ethernet TCP/IP link that is extended to the office-level of factory automation. The application is thoroughly presented with the highlight on real-time features; the QNX real-time operating system and Ethernet TCP/IP technology for the use in a networked automated factory are also described
