Connect the programmable controller,use the display screen to display,write the working parameters or input the operation command through the input unit(such as touch screen,keyboard,mouse,etc.),and realize the interaction between human and machine information.The touch screen is easy to use,sturdy and durable,fast response,space saving and other advantages,so that more and more system designers feel that the use of touch screen has considerable advantages.The touch screen consists of hardware and software.The user interface design can be completed by using the software,and the use of the computer can be greatly simplified in combination with the PLC programming.Control system parameters,store production recipes,and record equipment production data.The learning of touch screen can be carried out according to the following steps.First,carefully read the screen design manual for a certain series of touch screens to design the user screen;then design the touch screen screen operation to implement the corresponding PLC program;finally,open the touch screen and PLC programming simulation software for simulation debugging.

连接可编程序控制器,利用显示屏显示，通过输入单元(如触摸屏、键盘、鼠标等)写入工作参数或输入操作命令,实现人与机器信息交互的数字设备称为人机界面,俗称触摸屏。触摸屏以其易于使用、坚固耐用、反应速度快、节省空间等优点，使得系统设计师们越来越多的感到使用触摸屏的确具有相当大的优越性。触摸屏由硬件和软件两部分组成。利用软件可以完成用户界面的设计，结合PLC的程序设计极大的简化了计算机的使用，即使是对计算机一无所知的人,对不懂PLC程序编程的操作人员，也能够按控制要求设置控制系统参数、生产配方存储、设备生产数据记录等操作。触摸屏的学习可以按如下的步骤进行。首先针对某一系列触摸屏仔细阅读其画面设计手册进行用户画面设计;接着设计触摸屏画面操作实现对应的PLC程序;最后打开触摸屏、PLC编程仿真软件进行仿真调试。
