Abstract
This paper, we propose a Modbus communication method between PC and inverter system-asynchronous 3-phase motor through an interface designed in VisualBasic language. The construction of this communication interface is aimed at helping lecturers and students access industrial communication technology with modern electric drive systems, easily updating information and installing the inverter system via a PC. The research results have built an intuitive computer interface, updated the settings, showing the full operation information of a 3 - phase asynchronous motor inverter system. In addition, the results also show the ability to apply industrial communications for remote control and monitoring with modern electrical equipment in shipbuilding and industrial automation.
