Summary
This chapter has been a crash course in the basic mathematics of PLC programming. We have explored the basics of adding, subtracting, multiplication, and division, trigonometric functions, order of operations, and more. Knowing how to program equations into a PLC is a pivotal skill for any automation engineer. At the end of the day, if a PLC programmer cannot program mathematical equations, they can’t function as an automation engineer!
One of the biggest takeaways from this chapter is the use of built-in functions. Functions are very important in the realm of PLC programming and many more functions are supported that are non-mathematical. As such, the next chapter will be dedicated to exploring some of the fundamental functions that PLC programmers will often encounter.
