Q: Answer-Which statement is FALSE regarding Programmable Logic Controller?

A Programmable Logic Controller PLC is an industrial digital computer designed for automation of electromechanical processes, such as control of machinery on factory assembly lines. PLCs are widely used because they are rugged, reliable, and can be easily reprogrammed for different control tasks. They are optimized for real-time control in industrial environments and are specialized to interface with sensors, actuators, and other industrial devices. Therefore, the statement PLCs cannot be reprogrammed for other tasks is false, since one of the main advantages of PLCs is that they can be reprogrammed to handle new tasks without changing hardware.
