OpenPLC Programming Handbook

Turn a $35 board into a real PLC.

OpenPLC is the world’s first fully open-source programmable logic controller, and it runs on hardware you already own — a Raspberry Pi, an Arduino, an ESP32, or rugged industrial boards. With it you can program in the same IEC 61131-3 languages used in refineries, factories, and water plants, and watch your logic run on your own bench.

This fully illustrated, ladder-first handbook takes you from your very first contact and coil to a complete, running control system. You won’t just read about programmable logic controllers — you’ll build with them, chapter by chapter, on real hardware.

Inside, you’ll learn to:

• Install and configure the OpenPLC v4 Editor and runtime
• Write ladder logic — and use Structured Text and Function Block Diagram where they fit
• Master timers, counters, math, comparison, and memory addressing
• Build sequential control with Sequential Function Charts (SFC) — including how to make one actually run
• Design reusable function blocks, edge detection, and PID control
• Map I/O and Modbus registers across a dozen different boards
• Test your programs with a free copy of Ignition Maker before you wire anything
• Secure your controller the way real industrial sites do
• Extend OpenPLC to new hardware like the AutomationDirect Productivity Open
• Build a complete, real-world project from idea to running system

Whether you’re a maker, a student, a technician, or a professional engineer, this book gives you the practical, hands-on knowledge to use OpenPLC with confidence.

Fully revised for OpenPLC’s move to Autonomy Logic and the Version 4 runtime, this second edition is the current, complete guide — with refreshed security, IIoT, and hardware coverage, and dozens of clear illustrations throughout.

Write it. Run it. Hold it in your hand.
