"I am a small business owner and I had been fighting the software for countless hours because I had no way of knowing how to present data and structure my system logic within TIA portal. I had literally written the same program 6 times and trashed each version because I couldn’t find the flaws in my own mess of ladder logic.

After trying multiple other online classes and training avenues, I finally came across Hans’ courses. His first principles approach to program structure was such a relief and helped answer questions that I never thought I needed to ask. I watched the training videos a couple times and used the end result as a guide for my own software.

These courses helped me deliver on a huge project and created a foundation for a skill I now use on a daily basis. Two thumbs up. Thank you Hans for what you do and keep fighting the good fight."

"My name is Oleksandr, a marine electrical engineer from Ukraine with background in electrical instrumentation and control. While I frequently worked with PLCs during troubleshooting, my knowledge was limited, and I wanted to gain a deeper understanding of PLC programming to enhance my skills and career opportunities.

I enrolled in several basic courses, but they often just covered simple LAD instructions without real-world applications. While searching for better resources, I discovered a free video from PLCskilltree.com that explained PLC structuring with a practical example. The concepts were refreshingly new and eyeopening, making perfect sense.

Hans’s courses were comprehensive, challenging, and significantly contributed to my development in PLC and HMI programming. After the courses, I felt confident enough to create my own full-sized application for real-world equipment. Without hesitation, I recommend the courses on PLCskilltree.com to anyone seeking comprehensive and practical learning in TIA PLC programming."

"Before I found PLCskilltree.com, I found myself having to modify a very shabby Siemens PLC project in TIA Portal V16. The project was supplied with a package equipment system but lacked many safety and functional features. I had to quickly add a bunch of I/O modules, instrumentation, and logic to integrate it into my facility. On top of that, I had never used TIA Portal before - I was only familiar with Allen Bradley!

Then I discovered Hans’ courses. It was extremely useful to get up to speed with TIA portal very quickly and helped me get my project up and running. The focus on program organization and structure was especially useful and made all the difference.

I learned how good structure can make a PLC project more scalable, easier to troubleshoot, and easier to modify. Hans’ sample project is exactly what I like to see in professionally developed PLC projects. It is well worth the money to buy these courses. Thank you, Hans."

"I am from Wrexham, Wales, UK working in manufacturing for 28 years, starting as an electrical maintenance engineer. Over the last decade, I moved into machine controls, focusing on PLCs and Drives. Curious about TIA Portal’s tag-based programming and Profinet, I turned to video-based learning to expand my skills.

I found Hans’ PLC course on plcskilltree.com through a post on LinkedIn and was immediately impressed. Most PLC courses only cover basic logic with timers, counters, and simple integer moves. Hans’ training focused on real-world applications, like process tank systems with user-set parameters and animations. The lessons were clear, engaging, and delivered so well that they truly are simple to follow.

Since enrolling, I’ve adopted structured programming with UDTs and DBs, replacing my old, chaotic method of mapping data with markers. My confidence in TIA Portal has grown, and I now see large systems as modular units that you build up, not just a mass of rungs in one OB.

I have taken many video courses over the past few years, but Hans’ courses are perfectly delivered with excellent, relatable content. You feel like you have enhanced your skills, knowledge and experience in this training… just as it should be."

"My name is Candia Porter, and I am from Canada. Before I started learning TIA Portal, I had some experience with Allen Bradley PLC programming from college. As an Electrical Designer, I was tasked with commissioning machines using TIA Portal, but I found it difficult to step into another programmer’s brain and understand their programs. I didn’t know where to start.

I began searching YouTube for TIA Portal programming tutorials, hoping to find real-world examples related to my work. After watching several videos, I came across Hans’s video, “How to Structure Your PLC Program in TIA Portal Like a Pro”. I was totally sold by his course material - clear and well-organized explanations for programming TIA Portal applications. So I purchased his PLC & HMI online courses.

After taking Hans’s courses, I feel much more confident about writing my own TIA applications. I now enjoy programming and find that understanding the program also enhances my design concepts - an unexpected benefit. It doesn’t matter if you’re just starting out or if you are experienced, Hans’s courses are clear, full of professional tips, and easy to follow. Thanks, Hans!"

"Hi! My name is Marcin, and I’m from Poland. I was hired as a junior PLC programmer after the previous programmer left the company unexpectedly. They needed someone to handle PLC programming for machinery used in medical applications, using high-frequency welding technology. After just a month in the office, I was asked to program the latest version of their machine using Siemens TIA Portal, with only electrical drawings to guide me.

At first, I was afraid I’d end up with “spaghetti code” that would be impossible to debug, especially since I had never programmed a PLC application on my own. My wife and I were praying and somehow Hans’ course appeared to me as I was educating myself on the internet. I felt strongly that I needed it, so I asked my boss to buy it for me. If not, I was ready to invest in it myself.

Thanks to Hans’ clear explanations and step-by-step tutorials, I was able to confidently program my own PLC application. After completing the project, my boss wrote: “Mr. Marcin Okulczyk programmed a PLC and HMI for Medical-machine. His task was to set up a complete new program starting from zero. The end result was correct/professional and delivered in time”. Hans’ course was essential for my success."
