PCS7在莱钢大H型钢生产线中的应用

为满足现代化工业生产的需要,在莱钢大型H型钢项目中应用了西门子PCS7控制系统。该系统具有高速、高可靠性和强大的通信能力。以冷锯自控系统为例,通过对其编程过程的详细论述,可以得出Profibus-DP总线型拓扑通信网络的应用使得全部控制设备通信网络化成为可能。该系统不但为冷锯的精确定位和锯切提供了有利保障,为设备控制程序的逻辑性和连贯性的模拟调试打下了坚实的基础;而且也为类似大型自控系统的开发提供了借鉴依据。

Application of PCS7 in Large H-shaped Steel Production Line of Laiwu Iron & Steel Works

To satisfy the requirement of modern industrial production,the Siemens PCS7 control system with high speed,high reliability and strong communication capability is applied in large H-shaped steel project of Laiwu Iron & Steel Works.Take the cold sawing automatic control system as example;through discussing its programming process in detail,it is infered that the application of Profibus-DP bus topology communication network makes the networking of the communication of all the control equipment possible.The system offers favorable protection to the accurate positioning of cold sawing and saw cutting,and lays a solid foundation for the simulation debugging of the logicality and coherence of the equipment control program,as well as provides good reference for the development of similar large scale automatic control systems.
