触摸屏技术是继键盘、鼠标、手写板、语音输入后为普通百姓所易接受的计算机输入方式。利用这种技术，用户只要用手指轻轻地触碰计算机显示屏上的图符或文字就能实现对主机操作，从而使人机交互更为直截了当。这种技术方便了用户，是富吸引力的全新多媒体交互设备。
触摸屏的本质是传感器，它由触摸检测部件和触摸屏控制器组成。触摸检测部件安装在显示器屏幕前面，用于检测用户触摸位置，接受后送触摸屏控制器；触摸屏控制器的主要作用是从触摸点检测装置接收触摸信息，并将它转换成触点坐标送给CPU，同时能接收CPU发来的命令并加以执行。
触摸屏系统一般包括两个部分：触摸检测装置和触摸屏 控制器。触摸检测装置安装在显示器屏幕前面，用于检测用户触摸位置，再将该处的信息传送给触摸屏控制器；触摸屏控制 器的主要作用是接收来自触摸点检测装置的触摸信息，并将它转换成触点坐标，判断出触摸的意义后送给 PLC，它同时能 接收 PLC发来的命令并加以执行，例如动态地显示开关量和模拟量。
