摘　　要：PROFIBUS是目前国内外广泛运用的工业现场总线之一,它提高了过程控制中的分散外设及I/O口数据传输的安全性和可靠性。针对无轴印刷机外设数据传输要求较高的实时性和可靠性,该项目设计了基于C8051F020和SPC3的PROFIBUS智能I/O从站。本文着力阐述了智能从站的硬件设计,介绍了智能I/O从站模块与西门子300系列PLC主站在Step7软件环境下的组态及软件的调试以及提高系统可靠性的方法。PROFIBUS is most important and widely applied field bus in the industry field. Its applications make the process control more safe and reliable. Here, the design for the intelligent I/O slave based on C8051F020 and SPC3 is introduced, This kind of slave is designed for the shaftless printing machine, meeting the demand of modularization and reliability of industry filed, Furthermore, this paper illustrates the software environment of Step7 which is worked on series 300 of Siemens＇s PLC, Finally, how to improve the reliability of slave practically is illustrated.
