Introduction to Allen Bradley PLCs

Introduction to Allen Bradley PLCs

This course is designed to introduce newcomers and others who are looking for a solid background and want to confidently work with Allen Bradley PLC’s. In addition, participants will be taken through lessons gaining confidence and skills along the way in interacting and navigating Studio 5000. Studio 5000 is the newest software application used to configure, program and maintain the entire Allen-Bradley Logix 5000 family.

We start by introducing you to the 3 members of the “Logix” family of Allen Bradley PLC’s and give you a comparative look at their industrial applications.
No basic course would be complete without a brief history lesson as to why and how the PLC was developed. We will show you how the old style control ladder drawings evolved into current-day ladder logic which was the first programming method and still very common today.

Moving on to programming, you will be introduced to the common input and output elements that are seen on program ladder rungs. How physical devices interact with these elements and how they interact with each other is discussed in detail.

Even seasoned veterans have problems with “Controller Tags” used with the ControlLogix PLC. You will be taken through a process of creating “Controller Tags” correctly, and will be able to navigate a program that already has “Controller Tags” created.

The last part the course is devoted to the use of Studio 5000. After learning how to successfully launch Studio 5000, the lessons will take you through the steps of adding and configuring digital and analog I/O. There are a number of options when configuring I/O and safety should always be priority #1. As safety is always of upmost importance, we will discuss best practices and the possible repercussions of hardware fault conditions.

Introduction to Allen Bradley PLCs
  • 1. Allen-Bradley PLC Platforms

    When making use of Allen-Bradley PLCs, there are three main models to choose from.

    In this lesson you are going to learn the technical differences between the three families of Allen-Bradley PLCs, as well as which applications are most appropriate for each type.

  • 2. Anatomy of a Rung

    Before you program a Programmable Logic Controller, it is important to know the anatomy of a PLC program.

    Knowing the basic history of PLCs will help you understand the fundamental terms and concepts used when creating a program.

  • 3. Execution of a Rung

    In the previous video, you learned the basic anatomy of a Rung. As you now know, a rung is made up of a series of input and output elements.

    You can think of the input elements as being conditions, and you can think of the output elements as being actions.

    You can define the behavior of y...

  • 4. Execution of a PLC Program

    Now that you know how a single rung is executed, and how its results are stored in memory, you should be ready to learn about how a PLC executes a program as a whole.

    As discussed in previous videos, the PLC executes rungs in order from top to bottom, and each rung is evaluated from left to ri...

  • 5. How a program uses PLC Inputs & Outputs?

    As you now know, the behavior of a basic PLC program is very straight-forward. However, you might be wondering how this translates to the control of real-world devices.

    In the CompactLogix and ControlLogix line of Allen-Bradley PLCs, “Controller Tags” are automatically generated for all the av...

  • 6. An Introduction to Allen Bradley Using Studio 5000 Logix Developer

    As you may know, we have created hundreds of very informative lessons on PLC programming.

    We have worked in the Step7, TIA Portal and Factory I/O software environments.

    In this lesson, we are going to not only introduce a new PLC but also a new PLC programming environment.

  • 7. Locating Allen Bradley Components in Studio5000 - Part1

    In this lesson, we continue where we left off in the lesson titled: An Introduction to Allen Bradley Using Studio 5000 Logix Developer.

    That lesson had us launching software, opening the create dialog and making some selections that created our base project.

    We’ll start by opening and rev...

  • 8. Locating Allen Bradley Components in Studio5000 - Part2

    In this lesson, we are going to add a discrete output module and discuss the different configuration options and the information that can be found on various tabs.

    We will have an in-depth discussion about the Configuration tab and the ability to change the state of each output when the proce...

  • 9. Locating Allen Bradley Components in Studio5000 - Part3

    We are then going to add an analog module and start going through the many configuration options. We’ll explain the options and what they mean for you as a programmer.

    We’ll talk about some best practices and discuss why we follow those practices. With the many configuration options per chann...

  • 10. Locating Allen Bradley Components in Studio 5000 - Part 4

    In this lesson, we will configure a couple more channels of the Analog Input Module and finish out the report dialog.

  • 11. Locating Allen Bradley Components in Studio 5000 - Part 5

    In this lesson, we are going to add an analog output module, configure some parameters and have more discussion on the configuration.

  • 12. Creating Tags and Assigning Addresses in Allen Bradley - Part 1

    In this lesson, we are going to start creating some tags and assigning addresses to them.

    The first thing that we need to talk about is two Scope types in Allen Bradley, local or Program, and global or CPU.

    After discussing the Scopes, we jump right in and create some tags.
    Control Logix is a t...

  • 13. Creating Tags and Assigning Addresses in Allen Bradley - Part 2

    In this lesson we are going to continue creating discrete and analog tags and assigning I/O points to the tags.
