摘要
本文对PROFIBUS-DP现场总线的网络访问机制进行了详细的探讨,建立了PROFIBUS-DP主站间令牌访问和主从站间主从访问机制的模型,通过分析协议的编码效率、通信过程和通信时间参数,定性定量讨论了PROFIBUS-DP现场总线的实时性、确定性和网络利用效率,并得出有理论和实用价值的结论。
A detailed discussion on the MAC mechanism of PROFIBUS-DP is given in the paper. The model of message transmission among master stations and that between master and slave stations is set up to analysis the network throughput and time parameters, through which the real-time property, determinism and network utility of the PROFIBUS-DP is presented and meaningful conclusions drawn that helps to the integration and configuration of industrial communication system with PROFIBUS-DP.
