In this tutorial, we will show you how to use macros in HMI programming to read and write data from CSV files. CSV files are commonly used for storing tabular data, and being able to read and write from them can be incredibly useful in industrial automation settings.

We will start by explaining what macros are and how they can be used in HMI programming. Then, we will guide you through the process of reading CSV file data using macros, and show you how to display the data on your HMI screen.

Next, we will demonstrate how to write data to a CSV file using macros. This can be useful for logging data or for updating external databases.

Throughout the tutorial, we will provide clear, step-by-step instructions, and demonstrate each step using a practical example. By the end of the video, you will have a solid understanding of how to use macros to read and write CSV file data from your HMI, and be able to apply this knowledge in your own industrial automation projects.

So, whether you're new to HMI programming or an experienced developer looking to expand your skills, this tutorial is perfect for you!
