　　SIMATIC S7-200 SMART 集成以太网接口，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 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，64K 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。
　　控制系统工艺分析如下：
　　1. 在检查完无故障的情况下，启动设备。设备自动运行完成各个过程。
　　2. 加压延时过程，此时打开排气电磁阀。
　　3. 加压过程，关闭排气阀，打开充气阀。检测压力值是否正常，取模拟量值跟设定值做 对比，若压力值过低，则低压报警，同时停止加压过程，关闭充气阀，打开排气阀。
　　4. 平衡延时过程，关闭充气阀。检测压力值是否正常，去模拟量值跟设定值做比较，若超出设定值，则报警输出，同时结束平衡延时过程，打开排气阀。
　　5. 检出过程，此时取模拟量值跟设定值做比较，若超出设定值，则报警输出，同时结束检出过程，打开排气阀。
　　6. 结束延时过程，打开排气阀，延迟时间结束，关闭排气阀。
　　由于使用了 SMART LINE 触摸屏，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。
　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。
　　通过终端用户的使用， 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。
