A Programmable Logic Controller (PLC) is an industrial-grade computer designed to automate electromechanical processes in manufacturing and production environments. Unlike general-purpose computers, PLCs are built to withstand harsh industrial conditions, including extreme temperatures, humidity, and electrical noise. They play a crucial role in controlling machinery, assembly lines, robotic systems, and industrial processes by executing programmed logic in real time.
