Profibus通信监测仪的设计与实现

为满足Profibus系统调试的需要,设计了一种基于PC的Profibus通信监测仪,它能对接入总线的各种设备进行在线监测,实时分析以及故障诊断。实现了一种新型的报文识别方法,以适应总线高速传输的要求,并在此基础上增加报文解析功能,保证用户在不了解总线协议情况下亦能自如使用Profibus系统。试验结果表明,Profibus通信监测仪具有广阔的应用前景。

Design and Implementation of Profibus Communication Monitor

In order to meet the needs of Profibus system debugging,the design of Profibus communication monitor based on PC is described.The devices can be monitored on line,the devices real-time analysis and fault diagnosis are given.A new type of telegram identification method is proposed,which can adapt to the requirements of high-speed on bus.On the basis of this function,the telegram analysis function is increasd.This function can make the using of Profibus system easier,even if the user don't know the bus protoc...
