Peres, Fernando Luís TartariMüller, Felipe Luís2022-02-012022-02-012021http://repositorio.uricer.edu.br/handle/35974/386In recent years, the instrumentation and automation market has been demanding field equipment such as pressure and temperature transmitters, converters, positioners, actuators and controllers, among others, with high performance, reliability and availability. For this reason, communication between equipment and systems has become more important, with the intention of obtaining better results such as minimizing consumption, reducing process variability, reducing operating and maintenance costs, as well as ensuring process optimization. In this sense, this work presents a study regarding the profibus protocol applied in a biodiesel industry, exposing the essential characteristics of these protocols, taking into account a comparison between the implementation of a conventional automation network from 4 to 20 mA, profibus network and Ethernet/ IP, following the classifications of networks and the various existing protocols. In a second step, based on the knowledge developed through the exploration of the literature, a supervisory system was developed in order to enable the visualization of data in real time, the management of information and the operation of the automation system, which was divided into sequential steps: analysis and creation of the supervisory based on Factory Talk View software, elaboration of system blocks and tags related to the communication protocol.Thus, based on the results obtained and the knowledge developed through the exploration of the literature, the feasibility of using the profibus protocol was verified. Finally, the last stage of this work was dedicated to the development of an automation bench, with the objective of reading the information provided by the instruments and, in this way, validating the methodological procedures applied.pt-BREngenharia ElétricaAutomaçãoProtocolo ProfibusSistema de supervisórioTrabalho de Conclusão de Curso
