Comparing Best PLC Books
Not all PLC books are created equal. Some function as practical workshop manuals, while others are academic textbooks suitable for university courses.
We analyzed the top 3 contenders based on Theory Depth (how well they explain the 'why'), Practicality (real-world code examples), and Modernity (IEC 61131-3 standards).
Your Self-Study Roadmap
Don't try to learn everything at once. Follow this recommended sequence to effectively master PLC programming.
Build the Foundation
Duration: 4-6 WeeksStart with generic concepts independent of brand. Understand digital Inputs/Outputs (I/O), binary logic, timers, counters, and the scan cycle.
Pick a Platform & Practice
Duration: 2-3 MonthsChoose a major vendor (Rockwell Automation or Siemens) and learn their specific software IDE. This is where you connect your laptop to real hardware or a high-quality simulator.
Advanced Languages
Duration: OngoingLadder Logic is not enough for modern Industry 4.0. You must learn Structured Text (ST) for data processing and complex algorithms.
In-Depth Guide: Choosing Your PLC Resources
Finding the best books for PLC programming can be the deciding factor between struggling with basic concepts and mastering industrial automation. In 2024, the demand for automation engineers is skyrocketing, but quality training material is often scattered. Whether you are an electrician transitioning to controls, a student, or a hobbyist, building a library of high-quality PLC books is essential for self-study.
Deep Dive Reviews: Top 3 Picks
1. The Beginner's Bible
Programmable Logic Controllers (Petruzella)
This is widely regarded as the best PLC book for beginners. It is formatted like a college textbook, which means it is packed with colorful diagrams, photos of real hardware, and end-of-chapter quizzes. If you have zero experience, start here. It doesn't focus on one specific brand, which helps you understand the universal concepts first.
2. The Career Starter
PLC Programming Using RSLogix 5000
If your goal is to get hired in North America, you need to know Allen Bradley (Rockwell). Nathan Clark's book cuts out the fluff. It is a PLC programming book designed to get you comfortable with the Studio 5000 interface quickly. It’s less about electrical theory and more about "how do I make the machine run?".
3. The Future Proof
PLC Controls with Structured Text
Ladder logic is great, but complex modern factories run on Structured Text (ST). Tom Mejer Antonsen’s guide is the best book on PLC for IEC 61131-3 standards. If you want to work with Siemens, Beckhoff, or Codesys, this advanced knowledge is mandatory.
FAQ: Self-Studying PLCs
Can I learn PLC programming on my own?
Absolutely. By combining the PLC training books listed above with low-cost simulation software (like Connected Components Workbench or CODESYS), you can simulate an entire factory on your laptop. Many successful controls engineers started as self-taught hobbyists.
How much math do I need?
For basic ladder logic, you only need simple arithmetic and logical thinking. However, for advanced motion control and PID loops (covered in advanced PLC programming books), a good grasp of algebra and basic calculus is helpful.
Final Pro Tip: Theory is useless without practice. We highly recommend downloading a simulator alongside reading these PLC books. Reading code is different from writing it!
