摘要
在研究工业网络实时性要求的基础上,给出了工业以太网和实时以太网的定义,深入分析了6种主要实时以太网的通信协议,并概要论述了以太网运动控制、网络安全和以太网延伸至现场设备级等关键技术。同时,较全面地概述了我国EPA实时以太网技术及其标准。
On the basis of the study upon the requirement of real time performance of industrial network, the definitions of industrial Ethernet and real time Ethernet are given. Six of major communication protocols of real time Ethernet are deeply analyzed and some of the critical technologies, e.g., motion control, network security and Ethernet extension to field equipment level are expounded. Meanwhile the technology and standard of EPA real time Ethernet in our country are described comprehensively.
