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.

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.

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...

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...

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...

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.

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...

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...

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...

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

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

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...

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