How a 20-Year Automation Engineer's Complete Siemens PLC Video Library Is Quietly Turning Confused Technicians Into the Most Valuable Engineers on the Factory Floor

Published August 24, 2026  ·  9 min read  ·  Skillvolt Industrial Hub

If you have ever stood in front of a Siemens PLC panel while a fault alarm is screaming, and felt your stomach drop because you genuinely did not know where to start — you already know the feeling this article is about.

You look at the rack of modules. Red lights blinking. Someone is standing behind you asking "so what's wrong with it?" and you are trying to look calm while your mind is completely blank.

Maybe you have watched a senior engineer walk up to the same panel, plug in a laptop, go online in a few seconds, read something on the screen, and fix it in ten minutes. And you have wondered — quietly, privately — how they know what you do not.

Maybe you have been passed over for a promotion. Not because you are lazy. Not because you do not care. But because the job needed someone who could program and fault find a PLC, and that someone was not you.

Maybe you have applied for an automation role, felt confident walking into the interview, and then frozen the moment they asked you to explain how you would troubleshoot a ladder logic program that was not running as expected.

Maybe you have spent money already. A course here. An ebook there. Videos that were too theoretical, taught by people who have never actually stood in front of a live panel with an angry production manager watching over their shoulder.

Maybe you have spent hours on YouTube, piecing together fragments — a video on timers here, a video on ladder logic there — but never getting the full picture. Never getting the one thing you actually need: a complete, structured path from zero to confident.

And maybe — this is the one that stings the most — maybe you have had to call a vendor engineer to fix a fault that, deep down, you suspect you should have been able to fix yourself. You watched them do it. You paid the invoice. And you felt something you do not say out loud.

Your career is moving. But it is not moving fast enough. And deep down you know why.

Every day you spend guessing on that factory floor is a day someone else is getting the promotion you deserve.

Then Something Changed Everything

For years, the gap in the market was obvious to anyone paying attention. There were bits and pieces of PLC training scattered everywhere online — a free video here, a $40 course there — but nothing that took a technician from complete beginner all the way through to confidently fault finding live Siemens systems under pressure.

What existed instead was a huge, quietly circulating library — a professional Siemens automation engineer's complete recorded lecture archive. Over 300 lessons. Built over years of real classroom and real plant-floor teaching. Hardware. Programming. Real industrial application programs. Online diagnostics. Fault finding. HMI. PID control.

Skillvolt's team went through every single lesson. All 300-plus of them. Not skimming — watching, testing the programs, checking the logic, verifying that what was being taught actually matched what a technician would face on a real Siemens installation.

What became clear almost immediately was this: this was, lesson for lesson, the most complete practical Siemens PLC training either of us had come across anywhere — free or paid.

So the decision was simple. Package it properly. Structure it into clear modules. Make it available — at a price a technician anywhere in the world could actually afford — instead of leaving it buried in a format nobody could access.

The first engineers who got early access reported the same thing, over and over: this was not "another PLC course." It was the missing piece. The thing that finally connected hardware, programming, and real fault finding into one complete skill.

What This Course Actually Covers

Most PLC courses teach you to write a program. This course teaches you to THINK like an automation engineer.

There is a massive difference. Writing a program is one skill. Understanding why a program fails — and fixing it under pressure while a production line is down — that is the skill that makes you irreplaceable.

Compare This To What You Are Currently Spending — Or Losing

  • Vendor engineer callout fee to fix a PLC fault you could fix yourself — $200 to $500 per visit
  • Siemens classroom training course — $2,000 to $5,000 per week. Plus flights. Plus hotel.
  • Random YouTube videos — Free but incomplete, unstructured, and leaves dangerous knowledge gaps
  • Generic online PLC course — $200 to $500. Usually theory heavy with no real fault finding
  • Lost promotion opportunities because you lacked the skill to justify it — Priceless. And painful.
  • The real cost — Every month you spend without this skill is another month your career stands still while others move past you.

Siemens PLC Mastery gives you 300+ video lessons — the equivalent of months of classroom training — for a fraction of what one vendor callout costs.

Electrical Technician, Lagos, Nigeria
I'd been the guy who wires panels, not the guy who touches the PLC. Went through the fault-finding modules twice before I felt ready. Three months later my supervisor moved me into an automation support role I'd been trying to get for almost two years. Wish I'd found this sooner.

Our plant used to call the Siemens vendor for almost every fault on the line. Now I handle it. Took me a few weeks of going through the diagnostics module properly before I trusted myself on a live panel, but it stuck. My plant manager asked me directly what changed.

I came from instrumentation, not programming, so I was worried the course would assume too much. It didn't. Started from hardware basics and built up from there. That's exactly the bridge I needed to move into automation work.

Graduated with no practical PLC exposure — my degree barely touched it. Added this to my CV after finishing the modules and got called for an interview within a few weeks. They actually tested me on ladder logic and I wasn't lost, which honestly surprised me a little.

I used to avoid the PLC panel completely and let someone else deal with it. Now I'm the one people on site come to when there's a Siemens fault. Didn't expect that shift to happen this fast, honestly.

Oil and gas environment, so every unplanned stop costs real money. Siemens faults used to mean waiting on a vendor engineer to fly in. I handle almost all of it myself now. The fault-finding module alone was worth going through slowly, more than once.

Every automation job I applied for wanted "experience" I didn't have a way to get. Going through this gave me enough real, practical knowledge that I stopped freezing up in technical interviews. Still job hunting, but I'm actually passing the technical rounds now.

One Last Thing...

Picture yourself 90 days from today.

A fault alarm goes off on the Siemens line.

You walk to the panel. You go online. You read the diagnostic buffer. You isolate the fault. You fix it. You restart the line.

Your supervisor watches. Says nothing. But you see it in his eyes.

That is what this course gives you.

The question is not whether you can afford $18.

The question is whether you can afford another year without this skill.

P.S. — This course comes with a full 30-day money-back guarantee. You have nothing to lose and a complete career upgrade to gain.

P.P.S. — The $18 launch price is only available for the first 50 buyers. Once those spots are gone, the price returns to $58. Do not come back tomorrow and find the price has changed.

P.P.P.S. — Every day you delay is another day a fault alarm goes off and you are not ready for it. That ends today.

To your success,
