Introduction to Programmable Logic Controllers (PLC’s)


Date(s) - September 18, 2020 - October 23, 2020
8:00 am - 4:00 pm

EDC of Elkhart County


This five-day workshop provides the basic skills and knowledge you need to work with the programmable logic controllers (PLCs) found in a typical manufacturing plant. The course begins with a review of relay logic, and then you’ll learn PLC programming, including general logic, timers, counters, and math functions, followed by human-machine interface (HMI) programming. Each session includes one or more hands-on labs where you will practice implementing what you have learned on a self-contained PLC system.  PLCs used in this workshop are from Automation Direct, but the basic PLC knowledge and  skills you will learn are easily transferable between PLC systems.


You Will Learn:

  • Explain the hazards that exist when working with electrical systems and guidelines for preventing injuries.
  • Explain what NFPA 79 is and how it relates to PLC system design and programming.
  • Interpret, create, and construct relay ladder logic diagrams and circuits.
  • Explain the components of a typical PLC system and the functionality of each.
  • Distinguish between input and output signals and analog and discrete signals.
  • Interpret, create, construct, and troubleshoot PLC ladder logic diagrams and circuits using basic functions, timers, counters, and math functions.
  • Create HMI screens that function as part of a PLC program.
  • Explain basic steps for troubleshooting PLC systems.


Appropriate For

Engineering and maintenance personnel, technicians, and others who need an introduction to or a refresher of PLCs and PLC programming.



Attendees should have general technical competence and be familiar with Windows operating systems. Previous PLC and electrical experience is helpful but not essential.
