摘要

EtherCAT专为低周期时间的高效实时流量而设计，众所周知，它显示出一些低效率，其中包括高质量的主从同步。在本文中，我们研究了一个原型电路，它允许我们使用嵌入在EtherCAT帧中的PTCP实现主设备和从设备之间的高质量时间同步。该电路向后兼容现有的EtherCAT网络。我们提供测量数据，并对今后的工作提出建议。

Improving EtherCAT master-slave synchronization precision using PTCP embedded in EtherCAT frames: A proof-of-concept

Designed for efficient real time traffic at low cycle times, EtherCAT is known to display several inefficiencies which include high quality master-slave synchronization. In this paper we examine a prototype circuit that allows us to achieve high quality time synchronization between master and slave device using PTCP embedded in EtherCAT frames. This circuit is backward compatible to existing EtherCAT networks. We provide measurement data and make proposals for future work.
