Overview
I wrote this course with the intention of showing how Programmable Logic Controller systems are constructed, and how to get started on programming these systems. After taking this class, an engineer should be able to design and build a simple PLC controller.
This course was designed for electrical engineers with limited experience with PLC’s as well as engineers of other disciplines. Most engineers will come away with a deeper understanding of how to build and program a PLC system. This course also shows how software can replace hardware. This will help engineers as they economically apply PLC’s to various projects. Engineers in other disciplines will also find it useful to have an understanding of how Programmable Logic Controllers work, as they work with mechanical, chemical, and building systems. The more that we, as engineers, understand how things in other disciplines work, the better that we can do our specific jobs.
There is very little math involved in the doing of this course. It always helps to understand basic algebra. Sometoo much) understanding of Boolean Algebra is also helpful for understanding this course.
This course is built on understanding the parts of a PLC system, and how they work together to make an operating system.
The student must take a multiple choice quiz consisting of twenty questions at the end of the course to obtain PDH credits. It is my intention that the material presented in this course help the student to be better versed in Programmable Logic Controllers, and therefore be more comfortable when working with engineers, technicians, and craftsmen in the field.
