XFC: ultra-fast performance using standard components<\/strong>
\n12.5 \u00b5s cycle time, continuously maintained from the PLC to the I\/O signals: This is eXtreme Fast Control \u2013 XFC. With the presentation at Hannover Messe 2012, Beckhoff was underlining its technological leadership in fast control technology. The components for this record-breaking system are: a high-performance CPU \u2013 a Beckhoff Industrial PC with control software to match \u2013 TwinCAT 3; ultra-fast I\/O components \u2013 with 1 \u00b5s latency; and naturally the fast Industrial Ethernet system \u2013 EtherCAT.<\/p>\n

\u201cWhen we first presented EtherCAT in 2003, the performance of this new fieldbus technology was still miles ahead of the controller capability of the time. With TwinCAT 3 and the current IPC CPUs the gap is closing, although it’s still not possible to foresee when we will be able to make the maximum EtherCAT data throughput fully usable for machine controllers\u201d, says Dr. Dirk Janssen, Manager Software Development at Beckhoff and one of the inventors of EtherCAT. \u201cWith the 12.5 \u00b5s presentation we were showing what the Beckhoff system is capable of together with our EtherCAT Terminals.\u201d Dirk Janssen says that the bus cycle time, while exciting, is actually in itself not decisive: \u201cA fast fieldbus only becomes a fast control system with a capable controller and ultra-fast I\/O components. And only with EtherCAT can the highest performance of the fieldbus be implemented continuously through to the I\/O signals: All technologies that rely on bus couplers with a separate, local I\/O bus suffer here from system-related disadvantages.\u201d<\/p>\n

The presentation at Hannover Messe was composed exclusively of standard components. In typical EtherCAT style, the controller did without special fieldbus hardware and implemented the master in software. The EtherCAT Terminals were from the Beckhoff product portfolio and the fieldbus itself was standard EtherCAT, exactly as it has been known and standardised for years.<\/p>\n

With XFC, control loops are closed much faster and the delay times after transitions are drastically shortened. As a result, Beckhoff provides an innovative system to its customers that makes machines and plants significantly more efficient.<\/p>\n
