Summary
This chapter explored the integration of modules and components into a PLC system. The different types of PLC modules, sensors, motors, communication protocols, and more have been explored. We have also designed a simple PLC-based conveyor system to reinforce the concepts that were covered. At this point, you should have a basic idea of how hardware works and how it is used in an automation system.
As stated before, hardware is an important aspect of automation. However, as was also stated, it is not the only aspect that engineers should care about. Now that we have some hardware theory under our belts, we can move on to explore programming concepts by looking at the fundamental principles of programming!
