Performance Evaluation of the Switched EtherCAT Networks with VLAN Tagging

Abstract

EtherCAT technology is one of the most popular Real-Time Ethernet (RTE) solutions present on the market at this time. Due to its communication efficiency, EtherCAT is particularly suitable for networks with a large number of devices which demand short cycle times. This paper reviews the application aspects and implementation issues of the Switched EtherCAT networks with VLAN tagging, including their limitations, and provides guidelines for engineering staff in selection of the optimal solution when designing a specific automation system.
