The topic of my thesis is the automation process of hygienic flowing technologies. In
that, the focus is on a dairy-pasteur.
Basically, the system consists of a source and a target tanks and a pasteur with 3
sections. The task is to automate the flow of the dairy product and to control precisely
The structure of my thesis is built up according to the followings. Firstly, after the short
introduction I describe the Pasteur-process. Afterwards, the measure units and the
controlled devices are introduced. I suppose that the Siemens S7 PLC is known by the
reader and I write about that just briefly.
After all background information is given, the major part of my thesis comes with the
program-writing. Firstly, I introduced the structure of the program developed by me.
Thereafter, the main sections and functions are explained with particular examples.
In the nowadays automation, one of the most important view-point is the content of
the services of the operator panel as the result of the automation. Such a complex
system has to be developed with a visual appearance, which provides the most
comprehensive information for the operator. The HMI (Human-Machine Interface)
ensures the connection between humans and machines by colorful, graphical screen.
In conclusion, I describe the environment my development is applied in and I
summarize my thesis overall.
