EtherCAT Industrial Real-Time Ethernet In-Depth: Distributed Clocks, PDO/SDO, and Master/Slave Implementation

EtherCAT is an industrial real-time Ethernet protocol. This article explains its three core mechanisms: distributed clocks for synchronizing clocks across multiple slaves, the process data (PDO) and service data (SDO) communication methods, and concrete master and slave implementations. For robotics developers who need high-frequency, low-latency servo control, this is a practical introduction to understanding industrial bus communication.
