本文从分析工业以太网发展瓶颈出发,提出准对工业现场实时性和高可靠性的要求选用TCP/IP协议簇并进行扁平化处理,文中首先介绍设计的扁平化UDP/IP通信协议结构模型,后详细说明了工作流程并给出部分重要程序,本方案已成功用于Profibus总线与工业以太网之间的智能网桥设计中,实际应用表明,本协议具有通信速度高、易扩展、性能稳定的优点。 Based on the analysis of the bottlenecks in the development of industrial Ethernet, this paper proposes that the TCP / IP protocol cluster should be selected and flattened by the quasi-real-time and high reliability requirements of the industrial field. The paper first introduces the flattened UDP / IP communication protocol structure model, After detailed description of the workflow and gives some important procedures, the program has been successfully used in the design of intelligent bridge between the Profibus bus and Industrial Ethernet, the practical application shows that this protocol has the communication speed, easy to expand, stable performance The advantages.
