I found this course to be very well set out and structure to build on my basic knowledge of ladder logic. Thank you and looking forward to more courses you release to follow along with.

By Enatius on 3/7/2026

So far so good, clear communication, voice is not annoying, and the structure is awesome, get to read the context of the slide, prior to the voice dictation and understanding of whats on the slide (perview to the audience prior to explanation, is making it easier to get the message the author is trying to get out, easier to keep up with the chapters), looking forward to the next section.

The learning was at the next level. I don't have access to the TIA portal, but it still feels like learning in real time. I am so grateful to you, sir, for giving me great insights over ladder logic programming

By Subrato Dhar on 1/14/2026

The instructor has excellent verbal communication to explain the PLC programming concepts. Great effort put by the instructor to make student like me understand PLC ladder logic programming.

By Mark on 1/8/2026

I learned a lot and i was able to take it at my own pace. I lived it, my only criticism is that a couplke of the sections have a lot fo prereq knowledge required and it may be helpful to illustrate that. I have a cs degree so I knew about fsm, boolean algebra, etc. But someone less familiar may not know what that stuff is, and good practice would be to indicate that, unless you already did. I am new to udemy. so sorry if you did.

By Sidney Sharp on 11/12/2025

I feel this was an extremely good match for me. I have learned so much! From the outside looking in it seemed complicated but the instructor has made it incredibly easy to learn.

By Christopher [C] Cook on 10/7/2025

I am an engineering graduate looking to brush up on my automation skills for a promotion at work. So far this seems pretty relevant even though it is mostly review so far. Well made videos. Good audio also which is very important.

By Uwimana Kennedy Felix on 11/27/2024

this is a friendly course, I'm not yet have long time with it, but i hop to go father with it. the best thing to this course it introducing me to my daily work life, and taking me to be more professional.

By Paul Ainsworth on 10/8/2024

I think it was a good match. I did find that there were a few gaps or explanations for a few things. I do believe that when teachers are advanced and are teaching a beginners course they tend to gloss over or just forget certain things that might be important for us to know. I really liked the fact that I was able to stop or pause sections and really understand what was being taught. I definitely appreciate that about Udemy. Thank you!

By Sean Ray on 4/5/2024

This was a great introduction to Ladder Logic. I was hoping for more practice samples for real world machines, but this was a great course for introducing the different components and basics of ladder logic. For someone who is and operator and not a programmer this was easily digestible and understandable.
