Abstract

Programmable logic controller (PLC) plays a significant role in every era, either it is in field of automation, industry or educational purposes. As the demand for automation grows exponentially, control systems need to be easy to program, flexible, reliable, and cost-effective. This article provides an overview of PLC implementation in automation, industry, and education. This article reviews an investigation into the role of PLC in automation, industrial, and educational goals. PLC has its own limitations, but research shows that it has more benefits than limitations. After survey it will see that the PLC can be used in any application, either it is simple or complex control systems. The analysis conducted and focuses on the concept, operation, advantages and practical applications of PLC, as well as comparison with other control systems.
