摘要
文章主要从工业过程对所传递的各种信号的属性出发,讨论对于分布式多节点通信系统最适宜的通信机制。并以此为基础,进一步阐述工业以太网的发展状况和可能的发展动向,还讨论了以太网向现场层延伸必须解决的一些问题。最后指出,目前工业以太网合理而可行的发展是与现场总线相结合的路线。
In this paper some most adaptive communication mechanics for distributed multi-nodes communication system is discussed mainly from attributes of various signals which are transmitted in industrial process. Further development situation and possible development trends of industrial Ethernet are described, and some problems to must be solved are discussed when Ethernet extend to field layer. At last, it is pointed to that the reasonable and feasible development of industrial Ethernet would be combination with fieldbuses.
