PLC在钢坯加热炉的应用

Application of PLC in the Billet Heating Furnace

介绍了施耐德几种系列PLC同时应用于同一项目的控制中,如何通过以太网和MB+网实现不同系列PLC之间的信息交换。采用Unity Pro XL作为PLC的编辑软件,将逻辑运算程序设计在Quantum PLC中进行,而I/O信号转换由Premium PLC完成,利用Vijeo Look 2.6制作监控画面,容易地了解炉温及坯料运行情况,采用高速计数模块实现环形炉料位及钢坯移动控制地精确计算。改造后的自动化控制系统,具有稳定可靠、省时高效,集过程控制与界面操作、监控等多功能于一体的特点。

This article describes the several series of Schneider PLC are applied in the same item,how to carry out the information interchange among these different series of PLC by using Ethernet and MB + networks. Unity Pro XL as PLC editing software,the logic program running under Quantum PLC,and I / O signal conversion is completed by Premium PLC. The monitoring screen is made by using Vijeo Look 2. 6,thus it is easy to take the reins about the furnace temperature and condition of steel feed circling. It is adopting high-speed technology modules to calculate accurately the control of RHF level and steel feed circling. After the transformation,this automatic monitoring system is reliable,time-saving and efficient,and it unifies processing control and interface operation,monitoring and other multifunctional system.
