Recent years, ladder-type sequence control programs, we also need to experience a little bit of the latest programs, which are programmed by adding blocks, and we need to educate our students so that they can apply them immediately in practice.
The sequence control experiments were conducted based on the simulator. Sequence control is not controlled by memorizing a special language, but by combining a-contacts and b-contacts. Moreover, since the programs of the sequence are executed from the top down, it is very easy to understand when you think of it as a programming language. Also, I hope you have learned that by using CODESYS and Raspberry Pi, it is relatively easy to conduct sequence control experiments.
Let's use this book as a starting point to actually handle the sequencer and make use of it in practice.
