Technical requirements
The source code for this chapter can be found in the GitHub repo for this book. You can use the following URL: https://github.com/PacktPublishing/Mastering-PLC-programming/tree/master/Chapter%209.
We will also need some type of rendering software for drawing UML diagrams. For this chapter, I’m going to use draw.io for the rendering. If you prefer another piece of software, you are free to use it. Alternatives that you can use can include things like Google Charts, Visio, or any other software. You can use draw.io for free at the following link: https://app.diagrams.net/.
