What Will I Learn?
  • By the end of this course, you will be able to create a PLC program from scratch.
  • The primary and overall objective of this course is to give a novice an understanding of PLC programming, ladder logic, and the inner workings of a standard HMI (Human-Machine Interface).
  • Students will learn the difference between digital and analog signals and how to bring them into a PLC, process them, and send them back out.
  • Students will be familiarized enough with a sufficient variety of ladder logic instructions to create a complete PLC program from scratch.
  • Students will explore basic, standard controls techniques for things like HOA control, level control, pump control, and (on at least an introductory level) PID control loops.
  • Students will develop an understanding of alarm and notification programming, and the relevant considerations to safety and operator usability.
  • Students will be introduced to HMI development and given a general understanding of how an HMI program works.

Requirements
  • There is no software, hardware or experience required in order to complete this course, but practicing the techniques discussed on an emulator or live PLC are necessary steps toward eventual mastery.
Description

This course is designed to equip the novice with no prior PLC programming experience with the basic tools necessary to create a complete PLC program using ladder logic common to most current platforms.

Using the Rockwell software RSLogix 500 and FactoryTalk View Studio, we will be covering such topics as general controls, digital and analog IO, ladder logic programming, alarm / notification handling, HMI, emulation, best practices and more.

In the end, we will go through an entire, working PLC program and HMI line by line to solidify comprehension of the learning objectives.

Why Are There Four PLC Courses?

PLC I teaches you how to program with the focus on ladder logic, which is the most popular PLC programming language.  The goal is to teach you everything you need to know to make a PLC do what you want it to do.  You are also given all the software necessary to both CREATE and RUN your own programs live - right on your own computer.

PLC II forces you to take what you've learned and solve problem after progressively harder problem unassisted.  You get a spec and are told simply: "Make it work, and don't progress until you have."  After, you get to watch me solve each one as well.  By the end, you don't just know how to program - you are a PROGRAMMER.

PLC III gives you both knowledge and experience in FIVE different HMI / SCADA development environments.  By the end, you've created several COMPLETE visualization (screen) projects that you can actually run on your own computer (and SHOW PEOPLE in an interview) with no additional hardware.

PLC IV is only for the heavyweights.  This course teaches you how to program using all five IEC programming languages (plus one more) in multiple environments.  There are projects as well, so by the end, you have seen it all and DONE it all as well.  There won't be anything anybody can show you that you won't already be familiar with.

Who is the target audience?
  • This course is written for anybody who wants to become functional with ladder logic as quickly as possible.

Mercenary PLC-tamer

My background includes industrial automation and mechanical design. By degree, I'm an MBA, however after a few years on the road full-time as a management consultant, I fell into and in love with engineering.

My PLC / HMI experience includes projects from $10k up to about $40m, primarily within the realm of chemical processing and filtration. I am competent in RSLogix 500, 5000, FactoryTalk, PanelView, Maple Systems, C-More, Productivity 3000 and Arduino.

From a mechanical perspective, I've designed most of the same systems I program. My competencies in this area include full design, 3D modeling and drafting of assembly and fabrication drawings in AutoCAD and / or Inventor. I've designed mobile systems that were built in shipping containers up to one that filled a two-story building.

Before engineering, I developed and implemented CI (Continuous Improvement) management systems in companies across America in various industries to include a military finance organization, a printing company, a mortgage bank, a candy factory (my personal favorite), a nuclear products manufacturer, a major producer of coiled aluminum and several more.

Apart from things professional, I'm heavy into RC (heli, planes, drones, buggies and rally cars) and I also dedicate time to studying and teaching the Scriptures on my own websites (vanityandlies / vanidadymentiras).
