Opinions from Students

Łukasz CzekajSiemens S7-1200, S7-1500 PLC programming course in LAD/FBD language

The course was well structured and the first of its kind in which I participated. A very good level of detail in the discussed issues related to the environment itself, such as the TIA Portal, as well as to the hardware level. After some lessons, we have to do something ourselves, so that it is not a synthetic science, but is supported by practice. The most phenomenal thing is the homework included in the course, for which we get "live" support in case of problems with their implementation. If I had to choose a course of this type again, I would not hesitate to choose it again. I highly recommend it, it's really worth it 🙂

Rajesh LefèvreSiemens PLC course in LAD/FBD language

The courses offered by ControlByte are a very good way to quickly learn Siemens PLCs. The materials are comprehensive, supported by practical examples, the issues are discussed in simple and understandable language. The authors support students at every stage, verify homework, send tips and suggestions. The course allowed me to expand and supplement my knowledge in the field of PLC programming, which contributed to the application of knowledge in practice and to the launch of the first production implementation, of course successfully. I highly recommend and encourage you to attend the course!

Diego RobertsSiemens S7-1200 programming basics course

As someone just beginning my journey with PLCs, I found this course fantastic. It explains everything step by step, covering not only the "how" but also the "why" behind each concept. I highly recommend it and am eagerly awaiting future editions. Thank you—I can't recommend it enough!

Khaled A.Siemens S7-1200 Programming Course in Ladder/FBD

I've tried other PLC programming courses, and I can confidently say this one is the best by far. I highly recommend it to anyone looking to learn PLC programming!

Andrew MazurSiemens S7-1200 programming basics course

Hello 🙂 A well-prepared course for total beginners. The right amount of information does not overwhelm the recipient, as at the beginning of programming. The quality of the recordings is great (both video and audio). I am waiting for the continuation of this course as well as for the course at a higher level, because I want to master the LAD language for S7-1200 controllers. Everything I mentioned is best supported by an example of a real machine/line (as it has been so far).

Cezary LipskiSiemens Simatic S7-1200, S7-1500 PLC programming course in LAD/FBD language

A course at a very high level that met all my expectations. Materials in the form of video files and contact with the teacher - full professionalism. Another advantage of this type of course is the loose time frame that we can adjust to our pace of work. Kamil, who runs the course, thoroughly analyzes the homework sent to him and sends his observations in feedback. In my opinion, this course is a must-have item both for those starting their adventure with PLC programming, who want to learn the principles of good programming, as well as for people with experience.

Daniel CzerniakSiemens S7-1200 programming course

Hi! I want to thank you very much for the "SIemens S7-1200 Programming Course". The short films contained the maximum amount of information, without the so-called "pouring water". Pure knowledge, lots of examples, very interesting tasks to perform and tests. I am very pleased with both the quality of the courses and the service. It was my debut when it comes to online courses, so at the beginning I had some doubts, which later turned out to be completely unfounded. I highly recommend and look forward to the next editions 🙂
Regards

Tomasz GrzmilSiemens Simatic S7-1200, S7-1500 PLC programming on-line course in LAD/FBD language

A very nice course. The lecturers discussed theoretical issues in a professional and at the same time very accessible way and presented the possibilities of programming PLC controllers on many examples. I am satisfied and I can definitely recommend it to everyone who wants to start their career with controller programming.

Sebastian WencelPLC programming course S7 1200 1500 in LAD and FBD languages

The course is great. It has many useful issues necessary when programming PLC controllers. The presenters explain everything in a clear and legible way. Each module consists of short but very informative videos. This is an excellent option for beginners who want to program PLC controllers in the future. This course also teaches good practices when it comes to proper programming.

Thomas CzerwińskiCodesys programming course in ST language

A great course filled with substantive knowledge (very well-prepared materials) and examples that allow you to start your adventure with PLC. A big advantage is the support provided by the authors during the webinars. I would highly recommend.

Maciej PalaSiemens S7-1200 programming course - basic LAD.

Hello, Really great course, a large dose of information in great quality. Knowledge delivered at the highest level - bravo Controlbyte. From the basics of building a controller to programming a sorting line. I've done S7-1200 programming courses in books before, but an online video course is in a completely different league. The use of Factory IO is a huge plus for the student and contact with the instructors during the course is a pleasure. I am looking forward to the next stage of the course - Intermediate LAD. I definitely recommend it.

Daniel SzałkowskiSiemens S7-1200 PLC programming course - basics

A very good course for people who are starting their adventure with PLC. Step by step explained where it comes from. Lessons are organized in such a way that they do not overwhelm with too much information. Highly recommended and waiting for the next part 🙂

Ahmed JohanssonSiemens S7-1200, S7-1500 PLC programming course in LAD/FBD language

When I started, I was completely new to PLCs—my knowledge was limited to understanding inputs and outputs, and even college didn’t cover much on the subject. This course was a game-changer; it helped me transition into a new role at a machine manufacturing company. The explanations are clear, and the simulator allows for hands-on practice, making it easy to understand and visualize the concepts. Plus, having lifetime access to the course online is a huge bonus. I recommend it to anyone interested, and I’m excited for future editions of the course!

Piotr KoziełSiemens S7-1200 programming basics course

I am a person starting my adventure with PLC and for me this course was great. Explained step by step how and what to do and where it comes from. I highly recommend it and look forward to the next editions. Thank you and I recommend!!!

Erik NasserSiemens S7-1200 programming basics course

Hello! 🙂 This course is excellently designed for complete beginners. It provides just the right amount of information, making it easy to follow without overwhelming those new to programming. The quality of both the video and audio recordings is outstanding. I’m eagerly awaiting the continuation of this course, as well as an advanced course, to deepen my skills in LAD programming for S7-1200 controllers. I especially appreciate how real machine and line examples are used throughout—it's a fantastic learning approach!
