4.1.1 Features
 EtherCAT is a high-performance bus system based on Ethernet.
 Thanks to the integrated synchronisation mechanisms via "distributed clocks",
EtherCAT offers excellent real-time characteristics.
 Synchronisation with "Distributed clocks"
( 36)
 EtherCAT provides a higher bandwidth compared to CANopen:
– This enables motion and logic applications to be operated by the same bus.
– The number of the nodes to be controlled is higher.
– The maximally possible bus length is longer.
 EtherCAT can access all field devices via a common interface. Therefore, a division into
Logic fieldbus and MotionBus is not required.

Note!
For industrial PCs of the EL 1xx, EL x8xx, CS x8xx and CPC x8xx series in control
technology release 2.5, EtherCAT is not supported.
