摘要
生产者/消费者网络模式是一种能够提供多点传送功能的新型网络技术。在生产者/消费者网络模式的基础上,DeviceNet支持位选通、轮询、状态改变/周期等多种数据触发方式,可构建主/从、多主和对等网络结构。介绍了生产者/消费者网络模式的通信特性,分析了位选通、轮询、状态改变/周期等数据触发方式的通信机理。
Producer/consumer network model is the latest networking technology which can implement multicast function. Based on this model, DeviceNet provides manifold I/O data trigger modes, such as bit-strobe, poll, change-of-status (COS)/cyclic, and can construct master/slave, multi-master and peer-to-peer network architecture. The communication characteristics of producer/consumer network model was introduced, and communication mechanisms of bit-strobe, poll, change-of-state (COS)/cyclic I/O data trigger modes were analyzed.
