The analysis carried out in this technical paper highlights the concepts, working, advantages and practical applications of programmable logic controllers, along with a comparison with other control systems. A PLC aids in automation of a process by monitoring inputs and controlling outputs after making a decision on the basis of its program. It is commonly used for controlling many mechanical movements of heavy machinery and to control the voltage and frequency of power supplies. PLCs offer an array of advantages over other control systems, and have hence evolved as an important controller in industries these days owing to its large number of applications.
