PROFIBUS-DP是一种用于现场设备级控制系统和分散式I/O通讯的协议。本文从开发的角度描述了使用SPC3实现PROFIBUS通讯接口的一种方法，并在此基础上建立了一种采用PID算法的过程控制系统，最后利用OPC接口技术在以太网上实现数据服务与监控的分离，从而达到整个系统的网络化。

Abstract: PROFIBUS-DP is a protocol used in field facility control system and dispersed I/O communication. This paper describes a method of implementing the communication interface usingSPC3 by development point of view ，and establishes a kind of process control system using PID arithmetic, then implements the separation of data serving and monitored control by OPC interface technique on Ethernet, so that networked entire system..
