4.1 Overview
EtherCAT stands for Ethernet for Control Automation Technology. It is a communication
method for masters and slaves which uses Real-Time Ethernet, developed by the
German company BECKHOFF and managed by the EtherCAT Technology Group (ETG).
The basic concept of the EtherCAT communication is that, when a Data Frame sent from
a master passes through a slave, the slave passes the received data to the Data Frame
as soon as it receives the data.
EtherCAT uses a standard Ethernet frame compliant with IEEE802.3. Based on the
Ethernet of 100BASE-TX, therefore, the cable can be extended up to 100 m, and up to
65,535 nodes can be connected. In addition to this, when using a separate Ethernet
switch, you can interconnect it to common TCP/IP.
