Dear existing & future PLC software developers, I have published the 4th part of my free PLC programming using TwinCAT 3 tutorial.
In this video we will look into the various data types that are available in the IEC 61131-3 standard, pointers & references and how to work with arrays. We will cover why pointers can be dangerous and why you generally want to prefer to use references instead. Then we will finish the tutorial by looking at how we can convert between different data types. Also, what is the relationship between the amount of stars in the universe and TwinCAT? Watch the video to learn!
