A clock synchronization method for EtherCAT master
Microprocessors and Microsystems, 2016EtherCAT has been widely applied in the motion control domain due to its advantages of the fast response speed, low CPU usage and good synchronization performance. Although the built-in distributed clock (DC) synchronization mechanism exhibits strong performance between slaves, the method of clock synchronization between the master and the reference ...

Synchronization Improvement of Distributed Clocks in EtherCAT Networks
IEEE Communications Letters, 2017The aim of this letter is to improve the performance of clock synchronization in EtherCAT networks. Although EtherCAT synchronizes the slave clocks to the reference clock using a distributed clock synchronization mechanism, a synchronization error still exists between them. We propose a method to estimate and significantly reduce this error.

On the Wireless Extension of EtherCAT Networks
2017 IEEE 42nd Conference on Local Computer Networks (LCN), 2017EtherCAT is one of the real-time Ethernet protocols widely employed in industrial controls. However, its wireless extension is not straightforward due to the unique on-the-fly bus access method based on summation-frame. This paper explores the possibilities of interconnecting EtherCAT with wireless standards such as IEEE 802.11 and 802.15.4.

Performance analysis of switched EtherCAT Networks
2010 IEEE 15th Conference on Emerging Technologies & Factory Automation (ETFA 2010), 2010EtherCAT is a popular, real-time Ethernet network that features very high communication efficiency. However, because of the ring topology it relies on, cycle times increase when the network size grows larger (considering both the amount of process data and the network extension).
