Industrial automation is one of those fields that quietly runs the modern world. From conveyor systems in factories, to bottling plants, to high-speed packaging lines and robotic assembly cells — PLCs, HMIs, drives, and SCADA systems are everywhere. Yet for many aspiring engineers, getting into this world can feel confusing, fragmented, and unnecessarily difficult.
That’s why Control Junkies exists.
Why this site?
When you first step into industrial automation, you quickly realise there’s no single “clean path” to learning it.
You might learn a bit of electrical theory in college, maybe some PLC basics, perhaps a little ladder logic — but then you enter the real world and suddenly you’re dealing with:
- Real PLC platforms like Siemens, Allen-Bradley, or Beckhoff
- Field devices, sensors, and actuators that behave nothing like textbook examples
- Fault finding on live systems where downtime costs money
- Legacy code written 15 years ago with no documentation
It’s overwhelming at first — and often, you’re left filling the gaps yourself.
Control Junkies was created to bridge that gap.
What this site is
This is a free learning platform focused on industrial automation and control engineering, aimed at:
- Aspiring electrical engineers
- Apprentice and junior automation engineers
- Maintenance engineers wanting to upskill
- Experienced engineers looking to sharpen or refresh knowledge
The goal is simple:
To make industrial automation easier to understand, more accessible, and properly structured.
No fluff. No unnecessary theory without context. Just practical knowledge that reflects how real systems actually work.
What you’ll find here
Over time, Control Junkies will grow into a structured library of content covering:
- PLC programming (from fundamentals to advanced concepts)
- Ladder logic, Structured Text, and function blocks
- HMI design principles
- Industrial networking (Profinet, Ethernet/IP, Modbus, etc.)
- Drives, motion control, and servo systems
- SCADA systems and architecture
- Fault finding and real-world troubleshooting techniques
- Project walkthroughs and example systems
Everything will be written with one goal in mind: real-world application.
Who this is for
If you are:
- Just starting out in automation
- Struggling to connect theory with real systems
- Looking to move from maintenance into controls engineering
- Or already working in the field and want to go deeper
Then this site is for you.
Why “Control Junkies”?
Because once you get into this field properly, it’s hard to leave it alone.
There’s something addictive about understanding how machines think, how processes are controlled, and how everything comes together through logic, signals, and code. Once it clicks, you start seeing systems everywhere — and wanting to improve them.
That’s what this is about.
Final thoughts
Control Junkies is just getting started. The content will grow steadily, focusing on quality over quantity, and always staying practical.
If you’re here early, you’re in the right place at the right time.
Let’s build your understanding of industrial automation — properly.
