eXtreme Fast Control (XFC) is the technique that enables very fast, temporally high-precision reactions using EtherCAT, special I/O terminals and TwinCAT on the PC. Using EtherCAT distributed clocks (DC) and appropriate terminals, distributed latches or cam controllers can be implemented simply in this way.

• function blocks for the high-precision acquisition and switching of digital signals related to axis positions
• EtherCAT distributed clocks with the timestamp-based EtherCAT EL1252, EL2252 or EL2262 input and output terminals
• blocks for the conversion of DC time to position and vice versa
• convenient PLCopen-compliant TouchProbe block
• digital cam controller as PLCopen-compliant block

In conjunction with TwinCAT NC I, function blocks are available for high-precision switching of signals depending on the path position.
