摘要
以自动化工程中常用的PLC和PROFIBUS组成的单主站控制系统为研究背景,针对单主站系统信息处理的特点,建立了信息处理模型,从理论上分析了令牌目的循环时间对系统测控周期的影响,研究了单主站控制系统的响应时间。
A typical mono-master control system,composed of PLC and PROFIBUS,is considered as the research background,which is used commonly in automation engineering.Based on the characters of mono-master network,the processing model of high priority messages is set up.In theory the purpose of the token cycle time measurement and control cycle of the system and single master control system response time.
