EtherCAT® Features

High-Speed Ethernet

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.

Precise Synchronization

The DC (Distributed Clocks) in EtherCAT ®can lead to exact adjustment with less 1 µs in synchronization with master and slaves

Lower Solution Costs

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

Open Technology

EtherCAT® is disclosed to SEMI, IEC, and ISO standards. The master is available for various RealTime Operating System, such as INtime, Linux, and so on

EtherCAT® System Configurations

trans1

 

 

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® System Configurations



ECAT-data-transmit

 

EtherCAT® consists of Master and slaves. Each slave has its ESI file with .xml format. TwinCAT® is the 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.
