EtherCAT® Features

High-Speed Ethernet


Precise Synchronization


Lower Solution Costs


Open Technology


The transimission rate of EtherCAT® is 2 x 100 Mbit/s which makes EtherCAT® the Fast Ethernet with full-duplex feature. For example, 1000 digital I/O can be distributed to 100 nodes in 30 µs. The DC (Distributed Clocks) in EtherCAT®   can lead to exact adjustment with less 1 µs in synchronization with Master and slaves. With EtherCAT® filedbus, IPC can be replaced by PC-based system with smaller volume. Ethernet port is fine for EtherCAT® connection through CAT5 LAN cable. EtherCAT® is diclosed to SEMI, IEC, and ISO standard. The Master is available for various Real-Time Operating System, such as, INtime, Linux, and so on.

 

EtherCAT® System Configurations

  EtherCAT® consists of Master and slaves. Each slave has its ESI file with .xml format. TwinCAT® is the EtherCAT® utility which is developed by Beckhoff. The TwinCAT® automation suite forms the core of the control system. Through TwinCAT®, the Master can generate an ENI file with all the information of Master and slaves in .xml format.  

 

EtherCAT® Data Transmission

  In EtherCAT® network, the Master sends an Etherne frame passing through all of the slave nodes. Each EtherCAT® datagram is a command that consists of a header, data and a working counter. EtherCAT® datagrams are sent by the EtherCAT® Master to all connected EtherCAT® slaves. The data exchange is cyclically updated between Master and slaves.
