摘　　要：Ethernet Powerlink是一种基于IEEE 802.3的实时以太网。首先从原理、循环周期实现及配置等方面详细分析了EthernetPowerlink的核心调度机制,进而具体介绍了实时数据通信方式的实现及配置。这对Ethernet Powerlink的研究具有重要参考价值。下一步工作是要利用OPNET网络仿真软件建立一个标准化的Ethernet Powerlink通信网络模型,用于不同调度机制的试验及性能分析、评估。Ethernet Powerlink is a real-time Ethemet based on IEEE 802.3. The core scheduling mechanism and real-time communication pattern of Ethemet Powerlink are analyzed in depth. Firstly, the scheduling mechanism is analyzed in detail based on principle, cycling period, and configuration, then the implementation and configuration of real-time communication are introduced specifically. These are worth to be referenced in researching Ethernet Powerlink. The next stage of the project is by adopting OPNET network simulation software to establish a standardized Ethernet Powerlink communication network model, for using in experiment, performance analysis and evaluation with different scheduling mechanism.
