Learn Allen-Bradley PLC Programming from Scratch - No Electrical or Programming Background Required Every automated machine you've ever seen run - a conveyor that starts when a part arrives, a bottling line that fills and caps in sequence, a robot cell that waits for a signal before moving - is built on the same foundation: ladder logic running on a PLC. This book teaches you that foundation, step by step, using the exact platform used across modern automotive, packaging, and process industries: Allen-Bradley CompactLogix and ControlLogix controllers programmed in Studio 5000 Logix Designer. Written for the complete beginner, this guide assumes no prior electrical engineering or coding experience. Each concept builds on the last, moving from hardware fundamentals to a fully working capstone project you build yourself. What You'll Learn: - How PLCs work: the scan cycle, hardware architecture, and the Allen-Bradley product family - Navigating Studio 5000 Logix Designer - projects, the Controller Organizer, online vs. offline mode - Core ladder logic instructions: XIC, XIO, OTE, OTL/OTU, branches, and rung evaluation - Tags and data types, including UDTs, base tags, and alias tags - Timers and counters: TON, TOF, RTO, CTU, and CTD, explained with real-world analogies - Seal-in logic, interlocks, and why simple Start/Stop rungs aren't enough - Math, comparison, and move instructions for real process logic - A complete capstone project: a conveyor and diverter system with counting and reset logic, built rung by rung - Practical troubleshooting: reading fault codes, diagnosing wiring issues, and using the Tag Monitor - Organizing larger programs with routines and Add-On Instructions (AOIs) - A full glossary of PLC and ladder logic terminology for quick reference Whether you're an engineering student, a maintenance technician looking to move into automation, or an aspiring controls engineer preparing for your first PLC job, this book gives you a practical, hands-on path into the platform that runs a significant share of the world's factory floors. No hardware required. Every example can be built and tested using Studio 5000's built-in emulator. Start your journey into industrial automation - one rung at a time.
