A ?gua tem import?ncia fundamental na ind?stria farmac?utica, participa dos processos de limpeza de materiais e superf?cies, al?m de ser utilizada como ve?culo em formula??es, exigindo uma s?rie de especifica??es f?sico-qu?mica e microbiol?gicas. O processo de purifica??o da ?gua deve passar rotineiramente por um controle de qualidade r?gido e deve possuir um processo industrial conciso, automatizado e eficiente, de acordo com a legisla??o vigente. A utiliza??o de redes de automa??o e sistemas supervis?rios est? longe de ser novidade em qualquer tipo de ind?stria, por?m, neste caso, a planta industrial objeto de estudo n?o utilizava estas ferramentas. Para atingir o objetivo proposto fez-se a implementa??o de uma rede de comunica??o industrial entre os equipamentos da planta, atrav?s de uma rede padr?o MODBUS, uma rede instrumental com sinal de corrente el?trica e uma rede padr?o Ethernet. Concentrou-se os dados de leituras das vari?veis dos equipamentos no CLP mestre, este por sua vez ligado a um sistema SCADA. Este SCADA fornece ao operador uma vis?o panor?mica do processo, informando-o em tempo real o comportamento das vari?veis provenientes das etapas do processo, facilitando qualquer interven??o ou mudan?a no sistema. Os dados mais importantes s?o armazenados diariamente em arquivos na esta??o do SCADA, ficando dispon?veis para futuras auditorias ou durante a valida??o anual da planta, comprovando a efic?cia e seguran?a de todo o sistema. / This document propose the adequace of a water treatment station, through the development and implementation of an automation and supervision system for purified water production used in the manufacture of medicines. Water is of fundamental importance in the pharmaceutical industry, it participates in the cleaning processes of materials and surfaces, as well as being used as a carrier in formulations, requiring a series of physicochemical and microbiological specifications. The process of water purification must routinely pass through a strict quality control and must have a concise, automated and efficient industrial process, according to the current legislation. The use of automation networks and supervisory systems is far from novelty in any type of industry, however, in this case, the industrial plant under study did not use these tools. In order to reach the proposed objective, an industrial communication network was implemented between the plant equipments, through a MODBUS default network, an electric current signal instrument network and an Ethernet network. The variables input data of equipaments were concentrated in the master PLC, which was connected to a SCADA system. This SCADA provides the operator with a panoramic view of the process, informing it in real time the behavior of the variables from the process steps, facilitating any intervention or change in the system. The most important data is stored daily in files at the SCADA station, becoming available for future audits or during the annual validation of the station, proving the effectiveness and security of the entire system.
