PLC Programming refers to the process of creating instructions for a Programmable Logic Controller (PLC), which is a digital computer used for automation of industrial processes. PLCs are designed to monitor inputs, make decisions based on pre-programmed logic, and control outputs to manage machinery and equipment. The programming typically involves using languages such as Ladder Logic, Structured Text, or Function Block Diagram. These languages allow engineers to design control systems that can efficiently manage tasks like assembly lines, conveyor systems, and other automated operations, ensuring safety and reliability in industrial environments.
