摘要
本文介绍了西门子 PLC 混合网络在过程控制实验装置中的应用。控制系统在逻辑结构上分为两层:现场设备层和网络控制层,PROFIBUS 用于现场设备层,网络控制层采用工业以太网。文章对控制系统的设计思想、系统结构、组态方法进行详细的分析和论述。
This paper Introduces the Siemens PLC mix network application In the the process control system for experiment equipment.The control system is logically composed of two layers.device layer and control layer. Profibus is applied in field device layer and Industral Ethernet is adopted in network control layer. Paper explains design idea, system frame and configuration means.
