Effective Protocols for Industrial Communication

Abstract

The industry has undergone three revolutions mechanization, electrification, and informatization and now it is the era of fourth industrial revolution the Internet of things also called Industrial revolution 4.0 which is predicted its way into factory. The main vision of the fourth revolution is smart factory with globally networked and real-time capable industrial production. As a part of these, companies are aiming to create intelligent devices, storage systems, and supplies in industrial production. These intelligent devices in turn exchange data, perform action, control each other and also the products are aware of their current state. Furthermore, the challenge is to control of device in network with increase in their number and RT (real time) capability. The industrial communication network plays a vital role in automation industry. The industrial communication provides an effective means of data exchange, data controllability, and flexibility to connect other devices. The paper gives an introduction to industrial communication network and various industrial Ethernet protocols for real-time data exchange in automation industry. The paper mainly explains the effective role of EtherCAT protocol for the development of smart factory.
