PLCs are utilised in a variety of industries, including the steel industry, automobile industry, chemical industry, and energy business. With the advancement of all the many technologies in which it is used, the scope of PLCs expands considerably.
In industrial automation, a Programmable Logic Controller (PLC) plays an important role. Industrial computers are similar to programmable controllers. PLCs can be configured to monitor and operate a wide range of sensors and actuators; they process electrical signals and use them to execute preprogrammed commands in practically any application.
Automation is a procedure that is carried out automatically and is usually controlled by computers and sensors. In most cases, there is relatively little human intervention. To activate output devices such as motors or other machinery, input devices like as sensors and switches will operate with a controller or PLC. The PLC will proceed in the order that it was programmed.
A PLC's primary job is to automate processes by transmitting pre-programmed control functions to output devices in response to signals from connected input devices. A sensor, switch, thermometer, or relay is an input device that measures and communicates data from your system.
