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.

There is also free sequencing software that can be used on raspberry pi, and I realized that it seems to be possible to control sequencing on raspberry pi by using this software. So, I decided to use OpenPLC to control the sequence with raspberry pi. It took me a very long time to get it working because of the quirks in the software. It was also very close to "Impossibly hard game" as the students called it, as there was very little information available in the search. For this reason, I was tempted to throw everything out over and over again.
