Creating a Codesys Visualization in an application might seem complex, but with this step-by-step guide, it will become simple. In this post, we will show you how to add a visualization manager, create a screen, and connect variables to interface elements.

Adding the Visualization Manager

In the Project Tree, right-click on Applications.
Select Add Object.
Choose Visualization Manager.
In the Visualization Manager window, you will find various options – you can choose a visualization style.
Click the ADD button to add the visualization manager.

Creating the First Screen

Go back to the Project Tree and right-click again on Applications.
Select Add Object and add a new Visualization.
Name the screen, e.g., Screen_01, and confirm.
Now you have a view of the newly created screen.

Adding Interface Elements

Go to the Visualization tab.
Select the Lamp and Switches section.
Drag and drop a Dip Switch on to the screen.
Return to the Visualization Toolbox.
Choose Push Switch and drag it onto the screen.
Add a lamp by dragging and dropping it onto the screen.

Connecting Variables to Interface Elements

Click on the first button (Push Switch), go to Properties.
In the Variable field, double-click and select the three dots (…).
Expand Application, go to PLC_PRG, and select the xPB_Button1 variable.
Press Enter to confirm.
Repeat this process for the next button, selecting the xPB_Button2 variable.
Connect the lamp to the appropriate variable (xLamp) and confirm by pressing Enter.

Testing the Program

Close the Visualization Manager.
Make sure you have two screens open – PLC_PRG and Screen_01.
Go to Window and set them as New Horizontal Tab Group.
Navigate to Online and select Download Program to Simulation.
Ensure that you have checked the Simulation option.
Click Login, confirm by clicking Yes, and start the program.

Checking the Buttons and Lamp Functionality

Turn on the first button – the xPB_Button1 variable will change to True.
To turn on the lamp, press the next button – the lamp should light up.

Conclusion

Congratulations! You have successfully created a simple Codesys Visualization and connected interface elements to variables. If you want to enhance your automation programming skills, remember the basics of variables – we will explore this topic in future posts.
