Developing SCADA Systems to Monitor and Control Liquid and Detergent Factories

The SCADA system, which means Supervisory Control and Data Acquisition systems, are widely used in automatic management and control of producing and manufacturing processes throughout the world, reducing manpower and improving production efficiency. However, in Ethiopia, the manufacturing sector is at its infant stage and manual systems are mostly applied in existing factories. Therefore, in this paper we design a monitoring system based on existing SCADA system only in English and develops HMI software with GUI representing sub components to enable computerized controlling and monitoring of different parts in factories both in English and Amharic. Simulation results show interactions among sensors, actuators, SCADA hardware and HMI software in the overall system and real time data can be transferred and stored in databases. Finally, it is observed from PI controllers that tanker’s level can reach its steady state value after 0.15 seconds.
