Summary
In this chapter, we explored Boolean algebra, or, as it is sometimes called, Boolean logic. We have explored the basic operators, how to compute Boolean values, truth tables, and more. In short, this chapter may have seemed unnecessary; however, knowing how to calculate Boolean equations and create truth tables is a prerequisite to becoming a quality PLC programmer.
This chapter is the last in the design/logic section. Starting in the next chapter, we’re going to move on to more practical aspects of PLC programming and start writing working PLC code. As such, the next chapter will focus on getting CODESYS up and running and writing our first PLC program!
