摘　　要：为快速解决Profibus应用系统在设计、安装、调试及应用的不同阶段可能出现的各种故障,开发了一套基于Profibus总线的实时在线诊断系统"Profidiag"。首先对各阶段可能出现的故障进行分类,然后结合各阶段硬件及软件故障的诊断方法,给出了总线系统发生故障时的诊断策略。诊断系统根据诊断策略运用诊断功能块和Maintenance的诊断功能,通过对诊断报文的解析,实时动态地给出Profibus总线系统故障的诊断信息。现场运行表明,该系统能有效地捕捉各种故障并给出具体的诊断信息,具有一定的推广应用价值。To quickly resolve various failures that may occur at different stages of design,installation,commissioning and application of the Profibus application system,the real time online diagnostic system ＂Profidiag＂ based on Profibus has been developed.Firstly,the failures that may occur at each stage are classified; then,combining with the diagnostic methods for hardware and software failures at each stage,the diagnostic strategies for the failure occurrences in field control system （FCS） are given.In accordance with diagnostic strategies,by adopting diagnostic functional block and the diagnostic function of Maintenance,through analyzing the diagnosis messages,the diagnosis information for the Profibus system are dynamically given in real time.The field operation indicates that this system effectively captures various failures and gives specific diagnostic information,it possesses certain values of promotion and application.
