Introduction to Programmable Logic Controllers (PLCs)

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. The workshop includes 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.

Objectives:

• 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.

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

Workshop Length: 40 hours/5 days

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

Onsite Training: If you have multiple people to train from your facility, Purdue MEP can bring this training to you. For additional information on this option, please contact mepsupport@purdue.edu.
