From my experience, I have to say that RealPars is the most professional online training program out there. The instructors are easy to follow and clearly explain PLC theories with excellent supporting visuals and real-life application examples. I like that they provide a summary after each lesson that brings together all the information and makes it easier to retain. Plus, I can train anytime, anywhere. I’m a maintenance apprentice right now, but when I complete RealPars training I’ll be ready to go after the PLC programming jobs I want.

I work on electrical and instrument maintenance now, but my goal is to become a full-time PLC programmer. University courses take too much money and time. The RealPars video training method is great…the instructors are all experts and speak clearly so they keep my interest and are easy to follow. I’m eager to gain even more PLC expertise as new content is added.
