摘要：In this paper we propose an application written in LabVIEW through which a number of transducers or sensors are controlled so that the data from them are taken according to a certain algorithm and also this application realize the data processing. Control consists in selection for each of these transducers, their inputs selection and retrieves information from them. The physical connection between used transducers and master is made through RS-485 bus and the transmission protocol used is Modbus RTU.
