摘　　要：工业以太网进入工业控制领域是工业自动化的发展趋势 ,其中主要障碍是以太网的非实时通信。简要介绍了几种工业以太网的实时通信技术。侧重介绍分散自动化接口解决工业以太网通信实时性的方法———RTPS协议。Entering process control area of Ethernet is the developing trend of process automation, while the major obstacle is that Ethernet is not real time communication. Several real time communication technologies of industrial Ethernet are introduced in the paper. The RTPS protocol, the basis for data distribution underlying the Interface for Distributed Automation is emphasized. The performance of RTPS implementing real time communication is discussed.
