4 Way Traffic Light PLC Program EasyPLC

Traffic lights are used just about everywhere on busy roads around the world. They can help prevent traffic accidents and keep traffic flowing smoothly in the right direction by regulating the flow of cars, trucks, and other vehicles. The most common traffic light uses red, yellow, and green lights, along with arrows or flashes to indicate which lane should proceed when the lights change from green to yellow or red. Now you can visually see the 4-way traffic light by using the EasyPLC software suite. This provides an easy way of learning PLC programming.
4 Way Traffic Light PLC Program EasyPLCUsing the five steps for PLC program development, we will discuss how to program this traffic light. Four traffic lights and pedestrian panels with push buttons will be used. We will be using an Automation Direct Click PLC for this application, but the general methods can be used for any PLC. Let’s get started.

PLC Learning Series – Programming Steps

Developing a programmable logic controller (PLC) program can be broken down into five steps. These programming steps are as follows:
Five Steps to PLC Program Development
Step 1 – Define the task
Step 2 – Define the Inputs and Outputs
Step 3 – Develop a logical sequence of operation
Step 4 – Develop the PLC program
Step 5 – Test the program
These five steps to PLC program development will help you understand, program, and troubleshoot your automated machine.
PLC Learning Series – Programming StepsWe will look at each of these steps in more detail as we discuss the PLC programming development. Let’s get started.
