一种基于现场总线和PLC的中厚板轧机伺服控制系统应用分析

Application Analysis of Servo Control System Based on Field Bus and Plate Mill of PLC

随着社会经济的发展,以及计算机和PLC控制技术的发展,中厚板生产企业面临着激烈的市场竞争。因此,对于中厚板生产企业来说,要想使利润达到最大化,就必须实现低成本、高质量以及高成材率的指标。首先了解PLC在中厚板轧机中实现自动化控制的要点,针对西门子PLC、Profibus DP现场总线技术组成中厚板轧机的伺服控制系统,从控制系统的硬件设计、系统软件的设计、系统工艺的控制功能以及系统优化所实现的功能进行探讨和优势分析。

Along with the social economic development, as well as the development of computer and PLC control technology, production enterprises of medium - thick plate are facing fierce competition in the market. Therefore, for medium-thick plate production enterprises, they must realize low cost, high quality and high yield index in order to maximize profits. Firstly, it must learn the key point of PLC achieving the automation control in plate mill; in view of plate mill servo control system composed of Siemens PLC and Profibus DP technology, it makes discussion and advantage analysis from the hardware design of control system, system software design, control function of system technology and realized functions by system optimization.
