Free PLC Training Online — Learn PLC Programming and Earn Your Certificate

Search for "free PLC training" and you will find two categories. The first is YouTube videos and PDF manuals — useful for concepts, but passive. You watch someone else program. You read about ladder logic. You do not actually write any code, which means the knowledge rarely sticks when you sit in front of a real controller.

The second category is platforms like Alison that label themselves "free" courses. Many of these give you the video content at no cost, then charge for the certificate at the end — often $9 to $23 — after you have invested hours in the course. The bait-and-switch is well-documented. The result is eroded trust and learners who feel misled.

Good free PLC training does three things. First, it teaches concepts clearly — what a contact is, what a coil does, why the scan cycle matters. Second, it gives you a live environment to practice in: a real PLC simulator that runs your code against real machine behaviour. Third, it is honest about what is free and what is not, so you can plan accordingly.

This platform gives you the beginner curriculum at no cost — lessons, quizzes, embedded practice problems, and the in-browser simulator. The full curriculum and the completion certificate are behind a paid plan, and we tell you that on this page, before you create an account. Reading versus doing is the gap that most free PLC training never closes. We close it in the free tier.

The simulator is the part that makes this different from every other free PLC training course online. Instead of watching a video of someone else writing ladder logic, you open the browser, drag contacts and coils onto a rung, and click Run. The machine — a traffic light, a motor, a conveyor — responds to your code exactly as it would respond to a real PLC.

The free tier uses Allen-Bradley-style ladder logic syntax: XIC for normally-open contacts, XIO for normally-closed contacts, OTE for output coils. The same instruction mnemonics you will see in RSLogix and Studio 5000. No download, no Windows licence, no ControlLogix hardware required.

Every beginner lesson embeds a practice problem directly in the page. You do not finish a lesson and then hunt for an exercise. The exercise is there, in context, immediately after the concept is explained. This tight loop — read, understand, do — is how technical skills actually form.

The completion certificate confirms you finished every module in the full curriculum and passed all the graded exercises. It is not an industry-accredited credential like the ISA CCST — we state that plainly, because the distinction matters. An accredited certification is administered by an industry body and carries formal weight in hiring. A completion certificate confirms you did the work and can demonstrate the skills. Both are legitimate, and they serve different purposes.

For electricians transitioning into controls roles, a completion certificate backed by graded machine scenarios is often more persuasive in an interview than a video-course certificate with no verifiable exercises. You can point to specific scenarios you passed, the score you earned, and the skills each problem tested. That evidence is harder to fake than a completion badge from a passive video course.
