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.

PLC Learning Series – What are Inputs?

PLC inputs are one component of our PLC block diagram. The output actions of the PLC will be controlled based on the inputs. We will be looking at digital and analog inputs that can be wired to the programmable logic controller.

PLC Learning Series - What are Inputs?
We will be looking at wiring of a normally open (NO) push button, normally closed (NC) push button, 3 wire PNP sensor, and an analog sensor to the PLC. These will all be sinking inputs. Let’s get started.
