PLC Application
PLC is short for Programmable Logic Controller and it’s widely used in various industries such as steel, textile, chemical, automobile, oil and gas, and robotics among other industries.

PLC Explained
A PLC is a compact industrialized computer that has been adapted for the control of equipment and processes in an industrial facility from one location. In other words, PLC is the main key behind almost every automated control process.

PLC Function
The functions of a simple PLC can be divided into three categories: Input, Central Processing Unit or CPU, and Output.

1. Reading input: which detects the state of the proximity sensor that is connected to the PLC Input.
2. Executing the PLC Program: based on the information received from the PLC Input, and
3. Writing output: which sends commands to the pusher that is connected to the PLC Output.

PLC Programming
Engineers must write a program according to their process requirement, also known as a PLC Program, and then download it directly to the CPU of the PLC. The PLC Program is stored in non-volatile memory so it is not lost in the event of a power failure
