This guide provides an overview of the book's contents, highlighting key concepts, and chapter summaries. It can be used as a study guide or reference for individuals interested in learning about Programmable Logic Controllers.
Webb begins by contextualizing the invention of the PLC in 1968 (often credited to Richard Morley and Bedford Associates). The text explains the initial requirement: a device that could replace relay panels in the automotive industry to reduce downtime during model changeovers. It tracks the evolution from simple logic replacement to complex Process Control Systems.
While the Webb PDF is a fantastic historical and foundational text, the industry is moving toward soft PLCs (CodeSys) and edge controllers. Nevertheless, recruiters still ask interview questions directly from Webb’s chapters on timer accuracy and seal-in circuits.
