Review by Aditya Sadhukhan

This is an excellent course. I am a 3rd-year undergraduate student of Mechanical engineering & I didn’t have the basic concept of “Relay.” Now I have a clear idea about PLC. This course will be beneficial for beginners. Our instructor has introduced this course from a very basic level which helped me a lot. I learned so many interesting things that I would not have known if I did not take this course, especially the logic behind industrial automation. The second thing that I love about this course is using simulation software. Sharing thoughts is a great thing, and I definitely will share my knowledge with my classmates. I love this course. I will definitely take another online course in the future. Last but not least, the course is very informative, and it is a nice experience for me.

Review by Michelle Fugleberg Jensen:

I have an M.sc degree in energy, where we learned a little about the PLC and SCADA and how it was connected to the real world. But that was about it, except for a little hands-on experience with a Siemens PLC block. After the end of my education, I felt in the job description that I needed more experience within the field of PLC to get a job. That’s why I am taking this course, and so far, it is very understandable and has good examples of why the PLC is important.
