In this era of revolution technology, industrial automation system deals with advanced automation control technologies to have better control performance over complex processes. To increase reliability, productivity and quality while minimizing the production cost, process control industries must be driven by integrated controllers with high distributed control capability. Distributed Control System is a specially designed control system used to control complex, large and geographically distributed applications in industrial processes. In this, controllers are distributed throughout the entire plant area.

Industrial automation networks were slow and uncomplicated, no special components were required. For example, EIA-232, EIA-422/423, and EIA-485 were often used for the physical layers. In order to communicate with sensors and its peripherals we need an efficient protocol in terms of speed, reliability and safety indeed to communicate with HART, CAN, PROFI Bus, MOD Bus
