Dear existing & future PLC software developers, I have published part 17a of my free PLC programming using TwinCAT 3 tutorial.

TDD is the practice of writing tests before writing the implementation code. Writing software using the practice of TDD is something that has been around in the traditional software development industry for a while, but only recently has gained attention in industrial automation. In this series of videos, we will look at the theory of TDD, and then see how it’s done in practice.
