Object Oriented Automation Systems

This master's thesis is about the implementation and evaluation of a small object-oriented automation system. By using a realtime Java VM from Jamaica, a sheet feeding magazine from the machine Tetra Aptiva Aseptic has been controlled. The expectations included to achieve more structured and safer programming, better documentation through UML and to separate application developers from developers of basic functionality. The work has involved to understand the existing control program, to design an object oriented model in Java and to run it on a test rack. The system worked fine, and most expectations were fulfilled. The performance measurements indicated that the Java was fast but also had a slightly larger jitter
