Abstract. The purpose of this project is to create a Man Machine Interface (MMI) running at a standard PC. The software FIX32 from Intellution is used for the visualization. The casting process needs the implementation of a recipe functionality. By choosing the recipe a set of parameters is downloaded to the PLC. The PLC used is a S5 from Siemens and the communication with the MMI is done by a serial bus based on Siemens specifications..

Abstract. 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 on 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.

Abstract. The aim of this project is to automate the collection of chips that pile up during the production of power trains for cars. The production line consists of more than 50 machines which are connected via tubes with the central collecting unit. The transportation of the chips through the tubes are realized with underpressure, crusher devices, screw conveyors and valves. The actuators are controlled with an IPC from Siemens via Profibus modules covering an overall distance of more than 2 miles. Each unit has an operator panel to show the unit's status and alarms occurred. With the sequence chains based software a program is developed using principles of Time Slicing known from computer's Task Scheduling to ensure that every unit can deliver its chips and additional requests can be handled. With the Man Machine Interface (MMI) at the central unit the Time slice can be manipulated.

Abstract. The focus of this project is to automate a plant producing carrot mash by several heating processes. The plant is implemented in an existing production line having a conveyor belt system with a masticator at the product inlet and a centrifugal juicer at the outlet. The control strategy has to deal with a system having an irregular flow rate and shape of the product at the inlet and the requirement of a steady flow to the outlet. Furthermore the product transport is controlled by two pumps in a row realizing flow rates of up to 15,000 liter per hour of a viscous and inhomogeneous product. The heating processes are controlled with cascade controllers and disturbance variable compensation. A Man Machine Interface (MMI) is created running at a Touchpanel PC. It provides full manual control of all actuators, schematics of the plant, presentation of the measured values, graphs of the stored values, logging and presentation of alarms.

Abstract. The objective of this project is the automation of an ultrafiltration plant to accumulate the concentration of pharmaceutical products. A Man Machine Interface (MMI) is created running at a Touchpanel PC. It provides full manual control of all actuators, schematics of the plant, presentation of the measured values, graphs of the stored values, logging and presentation of alarms. An audit trail is implemented for all 160 parameters of the batch process.
