Programmable Logic Controllers
Robert J. Scoff, P.E.
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. Some (but not too 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.
