Programmable logic controller (PLC) is an electrical digital device that can be programmed through Codes and functions like as timing, logic, counting, and sequencing are stored in the PLC programmable memory. Machines and processes are controlled by these instructions. Variable frequency Drives are used in the industrial process for speed control and smooth start stop. As the need of automation increases significantly for the industrial processes, a control system needs to be easily programmable, flexible, reliable, robust and cost effective. It is human nature to always seek to improve the processes of its activities, in which Process automation has enabled industrial automation to make a major technological Advance. In view of this, the aim is to reduce the energy in the process manufacturing industries. In this paper a review on Importance of using PLC and drives to save energy in industrial process. Various applications of PLC and Drives in the energy research, industrial control, Application of monitoring and control of industries process are reviewed in this paper. Most industries are responsible for most of the percentage of GDP (Gross Domestic Product) movement in industrialized countries, at a time when companies seek to maximize their processes in an increasingly competitive market, always having to adapt any and all procedures with a view to technological advances, making a particular industrial process cleaner, which is of great importance to maintain the consumer market.
