Eduardo Cali

I’m a maintenance technician at my company and I recently transferred to automation. We’re working more and more with Siemens so I needed to get up to speed on the newest PLC software. RealPars videos feel like a real classroom experience. The instructors are great…they’re easy to follow and they make the lessons relevant to real-world applications and I like that. I definitely recommend RealPars.

Mario Flores

I tried other online training, but I have to say that RealPars instructors helped me connect the dots in a way the others didn’t. I was able to expand my Siemens knowledge…I only knew Allen-Bradley…now I understand the differences and similarities better. I find RealPars to be a professional and affordable way to get the big picture of PLC as well as gain lots of practical knowledge.
