Programmable Logic Controllers (PLC)

A Programmable Logic Controller is a digital computer used for automation of industrial processes. It has a programmable memory where users can store a variety of instructions. These instructions enable the PLC to perform tasks such as logic operations (like AND, OR, NOT), sequential control to manage the order of operations in a process, timing functions for controlling time – based events, counting tasks (e.g., counting the number of products passing on a conveyor belt), and arithmetic operations. PLCs are widely used in industries like manufacturing, power plants, and water treatment facilities due to their reliability, flexibility, and ease of programming.
