1.1 Introduction
EtherCAT (Ethernet Control Automation Technology) is a high-performance,
Ethernet-based fieldbus industrial network system. The protocol is standardized in
IEC 61158 and apply to automation applications that need faster and more efficient
communications. Short data update times with precise synchronization make
EtherCAT suitable for real-time requirements in automation technology.
1.1.1 EtherCAT Features
Functional Principle
In EtherCAT network, master sends an Ethernet frames pass through all of the slave
nodes. The Standard Ethernet packet or frame is no longer received, interpreted, and
copied as process data at every node. Instead, slave devices read the data addressed
to them and input data are also inserted in the same time while the telegram passes
through the device, processing data "on the fly". Typically the entire network can be
addressed with just one frame.

Protocol
Data exchange are cyclically updated between EtherCAT master and slaves. Data in
EtherCAT frames are transported directly within the standard IEEE 802.3 Ethernet
frame using Ethertype 0x88a4 and are processed by the EtherCAT Slave Controller on
the fly.
Each EtherCAT datagram is a command that consists of a header, data and a working
counter.. The datagram header indicates what type of access the master device would
like to execute:
