摘　　要：介绍了以S7-300系列PLC为核心的基于Profibus-DP总线技术架构的水库闸门控制系统。系统采用带有现场总线Profibus-DP接口的旋转编码器来测量闸门的位置,可靠性得到很大提高,并给出了通信程序。Based on the Bus technology of Profibus-DP, one kinds of the reservoir gate monitoring and control system is developed, the system is consisted with the PLC of S7-300 series as the core. In this system the position of the gate＇s displacement is measured by a rotating coder which provides a Profibus-DP interface, and the reliability is enhanced. Thecommunication program is listed.
