*Programmable Controllers: Theory and Implementation* contains expanded discussions of PLC Basics as well as advanced PLC applications. Control Engineering plays a fundamental role in modern technological systems.

The benefits of improved control in industry can be immense. They include improved product quality, reduced energy consumption, minimization of waste material, increased safety levels, and reduction of pollution. A difficulty with the subject, however, is that some of the more advanced aspects depend on a sophisticated mathematical background.

Arguably, mathematical systems theory is one of the most significant achievements of twentieth-century science, but its practical impact is only as important as the benefits it can bring. Thus, in this book, we aim to strike a balance which places strong emphasis on design.
