There are many types of touch screens on the market that correspond to PLC programming, here only take the mainstream Siemens touch screen as an example, in fact, the construction of the touch screen interface is not as difficult as we think. Start by opening the touch screen software, here with SIMATIC WinCC flexible. 

There are many types of touch screens on the market that correspond to PLC programming, here is only the mainstream Siemens touch screen as an example, in fact, the construction of the touch screen interface is not as difficult as we think. 

First, open the touch screen software, here we use the software "SIMATIC WinCC flexible 2008" as an example, and the interface looks like the following after opening it: 

As you can see in the image above, we can divide this touch screen interface into 6 zones:

A. Menu bar: many operation settings for saving, displaying, etc.;

B. Tool bar: convenient and fast operation buttons, such as enlarging and shrinking the working area;

C. Work area: used for the structure construction of the screen interface, etc.;

D. Project view: the established projects are displayed in the form of a directory tree;

E. Parameter area: mainly used to set attribute parameters for components in the working area;

F-Tool Window: The area where the components that make up the interface view are located.

Friends may not understand this, let's give you a comprehensive example, as shown below:

As you can see in the image above, we can create a split-screen interface for the touch screen in the project area on the left, where we play with the phone all day, I guess this is not difficult to understand. Then drag a button directly to the workspace in the tool window on the right, and then we can also edit the display text of this button in the property parameter area below. 

After the above explanation, do you feel that it is very simple? Programming without PLC instructions, just drag the button directly, is it different from what you imagined? You can follow me to chat privately and bring you more dry goods to share.
