S7-200在HVM膜过滤器控制系统改造中的应用

Application of S7-200 in HVM Membrane Filter Control System Reconstruction

随着科学技术的发展,模块化的小系统主要使用PLC+触摸屏的模式控制,很多企业基于减员增效的考虑也积极进行集中控制的改造。在HVM膜过滤器控制系统改造中,中盐吉兰泰氯碱化工有限公司自主设计了西门子S7-200PLC+海泰克PWS6600S型触摸屏的控制系统。基于此,有必要详细阐述该控制系统的硬件设计和软件编程。

With the development of science and technology, the modular small system mainly uses the mode control of PLC＋ touch screen. Many companies are actively pursuing centralized control based on the consideration of reducing staff and increasing efficiency. in the transformation of hVM membrane filter control system, China Salt Gilletai Chlor Alkali Chemical Co., Ltd. independently designed the control system of Siemens S7-200PLC＋ haitek PWS6600S touch screen. Based on this, it is necessary to elaborate on the hardware design and software programming of the control system.
