The use of the industrial Modbus network in control and measurement systems of laboratory stations

Abstract

This article presents the potential of using the Modbus TCP industrial computer network in measurement tests of electrical machines and devices used in laboratory stations. The Modbus interface is the primary communication channel for most measuring equipment for reading electrical parameters, such as current, voltage, and power, as well as mechanical parameters, such as rotational speed and torque at the shaft of the tested machine. The measurement system is designed to acquire data in steady states of the electric drive assembly, where the measured parameters indicate approximately the same value. The article presents the tasks and role of the measurement system in a modern approach to collecting and processing measurement data using intelligent communication devices.
