摘要
对ControlNet现场总线的网络访问机制进行了详细的探讨,建立了ControlNet以广播方式(Strobe)传送预定信息的信息流模型,通过分析网络吞吐量,信息平均等待时间和最长等待时间等参数,讨论了ControlNet的实时性,确定性和网络利用效率。
The paper gives a detailed discussion on the MAC mechanism of ControlNet.The message flow diagram of strobe type message exchange is set up to analyze the network throughput,message average waiting time and maximum waiting time, through which the article presents the real-time property,determinism and network utility of ControlNet and comes to some meaningful conclusions that may help to the integration and configuration for industrial control system.
