Beckhoff Automation says its new eXtreme Fast Control (XFC) technology is an ultra-fast control solution based on highly optimized control and communication architectures. Compared with current PC-based controllers, Beckhoff says XFC offers performance improvements by a factor of 10 and enables cycle times of 100 microseconds without having to give up central intelligence and the associated high-performance algorithms. In addition to highly optimized cycle times, XFC also offers improved temporal accuracy and enhanced resolution. An XFC system incorporates an advanced Industrial PC, ultra-fast I/O terminals with extended real-time characteristics, the high-speed Ethernet fieldbus, EtherCAT and TwinCAT automation software. With XFC, it is possible to achieve I/O response times of ? 100 microseconds.
