Design of Scada-Based Motor Monitoring System

Industrial progress triggered by the development of science and technology is centered towards the era of industrial automation. Industrial automation gives the industry the opportunity to develop production output. SCADA (Supervisory Control and Data Acquisition Systems) is a system that works on supervisory control of certain devices from a remote location and human operators can monitor and control devices from a computer screen by not being physically near the device. The purpose of this research is to find out how to solve problems in the control program on the Schneider PLC for motor control to improve the efficiency and reliability of system performance, with consideration of various technical, operational, and safety aspects. The initial step of this research is the design of a series of tools on SCADA-based motor monitoring that will facilitate the assembly process. The next step is to connect the HMI with the PLC, whether the HMI can work properly or not. After the HMI and PLC can be confirmed to work properly, the next process is to assemble the tool. After the tool is assembled, the researcher conducts experiments and measurements and records the results and analyzes whether the tool made can work properly or needs improvement again. Based on the results of the process of designing, making, and testing the design of a SCADA-based motor monitoring system, it can be concluded that the error of PZEM 004T in measuring voltage is 0.0198% in measuring current is 0.612%. In this test, for the three PZEM 004 T as slave 1, slave 2, and slave 3 connected to the RS485 converter and directly connected to the HMI, will experience data reading errors on the HMI because the data retrieval time is too fast and not in rhythm which results in some data not being recorded.
