I/O Terminals use eXtreme Fast Control(TM) technologies.
Press Release Summary:
EtherCAT® I/O terminals with time stamping latch exact system time at which edge changes occur; digital value output can occur at predefined times. Terminals with oversampling enable actual value acquisition or set value output with higher time resolution than communication cycle time. Distributed clocks with less than 1 µsec jitter and 1 µsec resolution are used for time synchronization across entire system. Fast I/O-enabled terminals offer input delays/switching times under 1 µsec.

Beckhoff Automation Announces I/O Terminals for eXtreme Fast Control(TM) (XFC)
Beckhoff EtherCAT® I/O terminals feature XFC technologies for oversampling and time stamping
MINNEAPOLIS, July 24, 2008 - In order to provide solutions suitable for industrial applications with the most demanding requirements for high speed and precise I/O, Beckhoff Automation has announced EtherCAT® Terminals for eXtreme Fast Control(TM) (XFC).
The EtherCAT Terminal system from Beckhoff is a comprehensive I/O family that is ideal for a wide range of applications with its high data throughput and distributed clock synchronization with a jitter of << 1 microsecond (µs). Newly developed XFC terminals offer special features that make them particularly suitable for fast or high-precision applications:
o EtherCAT Terminals with time stamping latch the exact system time at which edge changes occur. Output of digital values can occur at precise, predefined times.
o EtherCAT Terminals with oversampling enable actual value acquisition or set value output with a significantly higher time resolution than the communication cycle time. Distributed clocks with a jitter of << 1 µs and a time resolution of 1 µs are used for time synchronization across the whole system.
o Fast I/O is supported by digital EtherCAT I/O Terminals with very short input delays or switching times of < 1 µs.
XFC control technology enables extremely fast and highly deterministic response times. Its implementation requires integrated support of all hardware and software components involved in the control system: EtherCAT as the system fieldbus, EtherCAT Terminals as the I/O system, Industrial PCs as the control hardware platform, and TwinCAT as the automation and control software. All of these elements are available from Beckhoff Automation.
