Rett, J. and Palacios, F. (2002). "Automation of a Wine Stabilization Plant", Project, Crya, Darmstadt and Guth Engineering, Landau and Sektkellerei Schloss Wachenheim AG, Böchingen. The objective of this project is to automate a process used in the industrial production of wine. A program is written on a PLC to control the flow of the wine and several cleaning procedures using nitrogen, water, lye and/or acid. More than 100 valves are used to direct the flow of the liquids while providing a continuous process of up to two parallel batches. Standard PI, bang-bang and Split Range controllers are used to control the flow, the temperature and the pressure. The actuators are controlled via Profibus, AS-i and analogue signals. A Man Machine Interface (MMI) is created running at a standard PC. It provides full manual control of all actuators, schematics of the plant, presentation of the measured values, curves of the stored values, logging and presentation of alarms. The project is accepted as the masters thesis of F. Palacios at the FH Darmstadt in 2002. zurück
