Final exam
| Details |
Oral examination after written preparation. Based on a natural language description of a realistic automation task of appropriate complexity, the students develop a suitable model for a concurrent event-discrete control system. They justify the essential structures of their model with reference to typical automation system, development and maintenance requirements as well as task-specific specifications and prove that the model shows the required behaviour and quality, can be implemented on a controller device and can then be used as a control system that solves the given automation task. |
|---|---|
| Minimum standard | - Students extract the essential relevant information and solution limitations from the task specification and develop a reasonable petri net model of a control system using discrete signals and events of the technical process (signal interpreted petri net), taking into account essential automation quality criteria. - Students are able to simulate essential model sections in thought experiments and thus prove that the model under consideration meets special, required behavioral elements. - Students are able to describe and justify an appropriate implementation concept for their specific model on an industrial control device in its essential structures and properties. They show how the individual model elements and structures are mapped to the implementation concept. |
