Best PLC Programming Courses: A Comprehensive Guide

Programmable Logic Controllers (PLCs) are the backbone of modern automation, controlling everything from factory assembly lines to amusement park rides. Mastering PLC programming is a highly sought-after skill in today's industrial landscape. This article explores the best PLC programming courses available, helping you choose the right path to become a proficient automation engineer. Whether you're a beginner or an experienced professional looking to upgrade your skills, this guide will provide valuable insights into the top training options.

Why Learn PLC Programming?

The demand for skilled PLC programmers is constantly growing as industries increasingly rely on automation to improve efficiency and reduce costs. Learning PLC programming opens doors to various career opportunities in manufacturing, robotics, and process control. It's not just about writing code; it's about understanding complex systems and finding innovative solutions to real-world problems.

Key Benefit: PLC programming skills translate to higher earning potential and career advancement opportunities in the automation industry.

Types of PLC Programming Courses

PLC programming courses come in various formats, each catering to different learning styles and experience levels. Understanding the different types can help you choose the one that best suits your needs.

Online Courses

Online courses offer flexibility and convenience, allowing you to learn at your own pace and from anywhere in the world. They often include video lectures, interactive simulations, and downloadable resources.

In-Person Training

In-person training provides a hands-on learning experience with direct interaction with instructors and fellow students. These courses typically involve working with actual PLC hardware and software.

University Programs

Some universities offer PLC programming courses as part of their engineering or technology programs. These courses provide a more comprehensive and theoretical understanding of automation principles.

Professional Tip: Consider your learning style and schedule when choosing between online and in-person courses. Online courses offer flexibility, while in-person courses provide immediate feedback and hands-on experience.

Top PLC Programming Courses

Here's a curated list of some of the best PLC programming courses available online and in-person, based on factors like curriculum quality, instructor expertise, and student reviews.

1. Udemy: PLC Programming from Scratch

This course is designed for beginners and covers the fundamentals of PLC programming using Siemens S7-1200 PLCs. It includes video lectures, quizzes, and hands-on exercises.

2. Rockwell Automation: PLC-5/SLC 500 Programming

Rockwell Automation offers comprehensive training on their own hardware, including the PLC-5 and SLC 500 series. This course is ideal for those working with Allen-Bradley PLCs.

3. TIA Portal Training

Specifically tailored for Siemens TIA Portal, this training dives deep into the software environment and its capabilities, often a standard in modern industrial settings.

4. ISA (International Society of Automation): Various PLC Courses

ISA offers a wide array of PLC courses covering different brands and programming languages. Their courses are taught by industry experts and provide valuable certifications.

5. Local Community Colleges

Many community colleges offer introductory and advanced PLC programming courses that combine theory with hands-on lab work.

Important Note: Always check the course curriculum and instructor credentials before enrolling. Look for courses that cover relevant industry standards and programming languages.

Key Concepts Covered in PLC Programming Courses

A comprehensive PLC programming course should cover the following key concepts:

  • PLC Architecture: Understanding the components of a PLC system, including the CPU, input/output modules, and power supply.
  • Programming Languages: Learning different PLC programming languages, such as Ladder Logic, Function Block Diagram (FBD), and Structured Text (ST).
  • Basic Logic Functions: Mastering basic logic functions like AND, OR, NOT, and XOR.
  • Timers and Counters: Using timers and counters to control sequences and events.
  • Analog Signal Processing: Working with analog input and output signals.
  • Human-Machine Interface (HMI): Designing and programming HMIs to interact with PLC systems.
  • Communication Protocols: Understanding communication protocols like Ethernet/IP, Modbus, and Profibus.
  • Troubleshooting: Diagnosing and resolving common PLC programming issues.

Here's a visual representation of the distribution of time typically spent on different PLC programming languages during a comprehensive course:

Key Insight: Ladder Logic remains a fundamental language, but understanding Structured Text and Function Block Diagram is increasingly important for complex applications.

Choosing the Right PLC Programming Course

Selecting the right PLC programming course depends on several factors, including your experience level, learning goals, budget, and preferred learning style. Here's a step-by-step guide to help you make the right choice:

  1. Assess Your Experience Level: Are you a complete beginner or do you have some prior programming experience?
  2. Define Your Learning Goals: What specific skills do you want to acquire? Do you want to work with a particular PLC brand or programming language?
  3. Set a Budget: PLC programming courses can range in price from a few hundred dollars to several thousand dollars.
  4. Consider Your Learning Style: Do you prefer online learning or in-person training? Do you learn best through video lectures, hands-on exercises, or a combination of both?
  5. Read Reviews and Testimonials: Look for reviews and testimonials from previous students to get an idea of the course quality and instructor expertise.
