In my previous CODESYS article, I explained what CODESYS is and why it is an exciting and important technology in industrial automation.

We mentioned that CODESYS is a great platform to learn PLC programming on because the CODESYS Development System is available to download and use free of charge.

In this article, we will show you how to download and install CODESYS so that you can start developing PLC applications in CODESYS as quickly as possible.

Let’s get started by downloading CODESYS.

Download CODESYS

You can download CODESYS from the CODESYS Store.

In my browser, I navigate to the CODESYS Store and click on the button to download the 64 Bit version of the CODESYS Development System as shown here.

After clicking the link, a pop-up window appears and prompts me to sign in to continue downloading CODESYS.

Installing CODESYS


In this article, I have shown you how to download and install the CODESYS Development System.

Now that the CODESYS Development System is installed on your computer, you are ready to launch CODESYS and start developing control applications and visualizations.

If you are interested in learning how to develop control applications with CODESYS, you can check out our course CODESYS 1: Introduction to PLC Programming.

This course gives you a detailed introduction to CODESYS and shows you how to write and test your first CODESYS application and develop a visualization for the application.

At the end of the course, you will receive a certificate of completion signed by WAGO proving that you know the basics of developing PLC applications with CODESYS.
