This document propose the adequace of a water treatment station, through the development and implementation of an automation and supervision system aimed at the production of purified water 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 vehicle 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 a Ethernet network. The data of readings of the equipments variables were concentrated in the master PLC, which in turn was connected to a SCADA system. This SCADA provides the operator with a panoramic view of the process, informing it in real time of 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.
