PLC Programming for Industrial Automation

Master PLC programming from the ground up with this comprehensive, hands-on guide covering all five IEC 61131-3 languages: Ladder Logic, Structured Text, Function Block Diagram, Instruction List, and Sequential Function Chart.

Written for both aspiring and working engineers, this book walks you through PLC hardware fundamentals, software environments, core programming concepts, timers, counters, analog I/O, communication protocols, and safety practices — then applies them across seven real-world case studies including conveyor belt control, tank level management, HVAC automation, and a traffic light simulation.

Advanced chapters cover Industry 4.0 connectivity, MQTT and OPC UA integration, IIoT edge computing, AI-driven predictive maintenance, and cybersecurity essentials for control systems. Eight comprehensive appendices provide quick-reference symbol tables, sample programs in every IEC language, a full troubleshooting guide, a glossary, vendor comparison tables (Siemens, Allen-Bradley, Schneider Electric), FAT/SAT testing procedures, and a 20-industry SCADA applications reference.

Whether you are setting up your first PLC or hardening an enterprise control network, Practicing Engineers Network delivers the depth, examples, and clarity to take you there.
