在同级别小型 PLC 中。因此终确定了用S7-200 SMART PLC + SMART LINE 700 IE触摸屏替换了欧姆龙PLC+维纶触摸屏的控制系统的方案。
4产品硬件配置
SIMATIC S7-200 SMART具有集成PROFINET接口,实现低成本与编程设备的通讯、强大的集成工艺功能,有效的解决方案,满足自动化需求、和灵活的可扩展性、安装简单方便、可拆卸的端子、紧凑的结构可大大节省了控制柜安装占用空间等特点。因此系统采用了SR40 CPU AC/DC/RLY的PLC作为控制中枢,其电源为AC220V,节省了电源模块、数字量输入为DC24V 24点,可直接与输入点连接、16点输出为继电器输出,干触点电压为5~30VDC或5~250VAC,电磁阀的线圈和接触器的线圈供电电压为AC220V,故可直接与PLC输出电路连接,使系统简单可靠。
SMART LINE 700 IE触摸屏准确地提供了人机界面的标准功能,经济实用,具备高性价比。具有集成PROFINET(以太网)接口,实现低成本与PLC控制设备的通讯,方便,快捷,强大的通讯功能, 256色真彩显示,800 X 480 dpi宽屏显示设计和传统屏幕相比具有更大的可视面积,使单个画面中可以显示更多的信息,让操作员具有更舒适的视觉体验,高分辨率使画面更清晰,画质更细腻。由于使用了SMART LINE 700 触摸屏,使得设备界面更加美观,大方,也大大提高了操作的灵活性。下图为触摸屏操作界面。见图5、图6、图76应用体会
SIMATIC S7-200 SMART自动控制系统与开关按钮系统比较,增加了监控功能,具有可靠性强、安全性好、准确性高等优点,可节省人员的编制,大大减少因人为的误操作或开关损坏而造成的故障,从而提高了工作效率,并相对提高了社会经济效益,是一种有效而实用的自动控制系统。
通过客户的使用,证明了气密测漏机控制系统用 PLC 控制的方法是切实可行的。气密性检测装置采用 SIMATIC S7-200 SMART PLC 控制器能大大地提高系统的可靠性和极大地提高了设备自动化程度,并使操作程序更加简便,客户较为满意。the dual PROFIBUS-DP fieldbus network to form the station control level of the system. Water is the basic material condition related to human survival and social development. It is a limited and irreplaceable precious resource and an important guarantee for the sustainable development of economy and society. In recent years, with China's rapid economic growth, the development of urban intensive areas such as the Pearl River Delta has ushered in an unprecedented period of opportunity. However, the progress of industrialization has also led to problems such as water supply shortage and water pollution, and even serious "ecological crisis" events. The state has paid a huge cost of resources and environment. The contradiction between economic development and resources and environment is becoming increasingly acute and needs to be solved urgently.

The State Council issued the outline for the reform of sewage treatment in the Pearl River Delta, and pointed out that the discharge rate of domestic waste should reach
