It doesn't. The electrical world has been using contactor diagrams for complex logic for decades, and with the inclusion of more advanced computer components ladder logic (still the same concepts, symbols and logic)

It's typical to see a handful of symbols handle what would take a hundred of lines of code for the level of user interface usability, validation, and core functionality.

- lithos 9y agoQuite a few PLCs have ladder logic as a programming language as a selling point. For physical systems it is pretty true.
