A novel design and development of PLC - HMI and Ethernet based system is used to monitor and control various process variables such as temperature, pressure, level and flow as MIMO (Multiple Input Multiple Output) system in a petro-chemical industry. The project consists of two modules, one is monitoring of these parameters and the other is controlling of those parameters. In this design by using B&R (Bernecker and Rainer) - HMI (Human Machine Interface), the monitoring of the process is done and controlling is performed by PLC (Programmable Logic Controller). In this work in order to transfer the data from plant to the central control room in a single Ethernet cable is used rather than using enormous number of cables so as to reduce the time due to transportation lag and thereby to improve the efficiency. A prototype model is developed, executed and finally validated from the data accumulated from a Petrochemical Industry. From the results it is highlighted that while using PLC - HMI and Ethernet cable, the variables performed output without transportation lag of 15 seconds which will improve the overall plant efficiency, safety and performs online monitoring and control.
