摘　　要：针对印刷机外围设备分散、数据传输信息量大、实时性和可靠性要求高等问题,设计一种基于PROFIBUS-DP协议的I/O从站,用于表格印刷机的分布式控制系统。控制系统由监控计算机运行的软件PLC程序,通过PROFIBUS通信卡与现场I/O从站进行通信,形成分布式控制网络。介绍分布式控制系统的整体结构、工作原理及特点,分析PROFIBUS-DP协议,详细说明采用微控制器C8051F020和协议芯片SPC3开发I/O从站的硬件电路、软件设计流程,给出基于PRO-FIBUS现场总线的分布式控制系统网络组态与调试的方法。经系统测试和实际运行表明,I/O从站与监控计算机通信可靠、准确,实时性满足了印刷机控制系统的要求,具有一定的参考价值和广阔的应用前景。Countering the problems existing in the printing machine, such as the excessive and distributed peripheral equipment, much information exchange, the reliability, veracity and real time feature of data communication, a distributed control system based on PROFIBUS-DP is designed. The soft PLC is studied and realized on the platform of monitor host computer. Via PC-PROFIBUS card, the master computer and I/O slave nodes can communicate with each other directly,like a distributed network. The system structure is more concise. The function of distributed setting and concentrated control is realized in this system. The whole structure and principle of system, the hardware circuit of I/O slave on the C8051F020 and SPC3, the software programming and the testing experiment were discussed in detail. Practical using shows that this distributed control system has the better control effect, indicates it＇s brilliant and validity beyond traditional control methods and is suitable for similar practical engineering.
