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 your program by determining what conditions need to exist for certain actions to be performed.
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.
