Example<br />
40 Axis (each 20 Byte Inputand Output-Data)<br />
50 I/O Station with a total of 560 <strong>EtherCAT</strong> Bus<br />
Terminals<br />
2000 Digital + 200 Analog I/O, Bus Length 500 m<br />
Performance <strong>EtherCAT</strong>: Cycle Time = 276 µs<br />
at 44 % Bus Load, Telegram Length = 122 µs<br />
in spite of this cycle time still 56%<br />
bandwidth remaining, e.g. for TCP/IP<br />
