摘 要: 工业控制网络对网络的实时性要求很高,不仅要求传输速度快,数据传输还要具有确定性。以太网的通信存在不确定性,不能满足实时性要求,成为以太网应用于工业控制领域的主要障碍。本设计实现的实时以太网就是网络中每个节点的通信被严格地限定在规定时间内,确保在同一网段内同时只有一台在发送数据。 Industrial control net is a special applicative network, it demands high desired real time processing and deterministic. Non-deterministic communication of ethernet which can't meet the real time demand of industrial control has become a main obstacle in application on filed device layer network. Real-time Ethernet implemented in this design is to build a high speed , deterministic network over traditional Ethernet . The communication among work stations is limited in deterministic time intervals , which guarantte that only one node can send datas in a certain time.
