Preface
Programmable Logic Controllers: Hardware and Programming is an
introductory text that explores many aspects of PLCs in an easy-to-understand
manner. The key concepts of PLCs are discussed using a comprehensive approach to
enhance learning. The text organization begins with basic concepts and progresses
to system level applications. Applications, testing procedures, and operational
aspects of PLC equipment and systems are discussed. This textbook emphasizes
the PLC’s practical use in industry.
The programmable logic controller was first introduced in the automotive
industry in the late 1960s. Today, PLCs are found throughout all manufacturing
industries and are increasingly found in commercial building automation systems.
Knowledge of selecting, wiring, and programming PLCs is required in many
career fields, including industrial controls, automation engineering, and
industrial maintenance.
This textbook describes the most common programmable logic controller
functions and provides examples using the Allen-Bradley Small Logic Controller
(SLC 500) series. There are a few software simulators for the SLC 500 for your
choosing. A quick web search can yield results from a variety of suppliers and
prices. The last chapter of the text discusses the next generation RSLogix 5000
software. PLC theory and PLC selection for various applications are explained.
PLC wiring and programming are also covered with numerous examples.

G-W Integrated
Learning Solution
Together, We Build Careers
At Goodheart-Willcox, we take our mission seriously. Since 1921, G-W has been
serving the career and technical education (CTE) community. Our employee-owners
are driven to deliver exceptional learning solutions to CTE students to help prepare
them for careers. Our authors and subject matter experts have years of experience
in the classroom and industry. We combine their wisdom with our expertise to
create content and tools to help students achieve success. Our products start with
theory and applied content based upon a strong foundation of accepted standards
and curriculum. To that base, we add student-focused learning features and tools
designed to help students make connections between knowledge and skills.
G-W recognizes the crucial role instructors play in preparing students for careers.
We support educators’ efforts by providing time-saving tools that help them plan,
present, assess, and engage students with traditional and digital activities and
assets. We provide an entire program of learning in a variety of print, digital, and
online formats, including economic bundles, allowing educators to select the right
mix for their classroom.
Student-Focused Curated Content
Goodheart-Willcox believes that student-focused content should be built from
standards and accepted curriculum coverage. Programmable Logic Controllers
also uses a building block approach with attention devoted to a logical teaching
progression that helps students build upon their learning. Content is presented in
small, focused chapters to help students master concepts before moving on. We call
on industry experts and teachers from across the country to review and comment
on our content, presentation, and pedagogy. Finally, in our refinement of curated
content, our editors are immersed in content checking, securing and sometimes
creating figures that convey key information, and revising language and pedagogy.
