To allow a rapid abstract development and reuse in embedded systems nowadays component-based system development is often used. However, control and monitoring at runtime for adjustment and error identification often take place using different domains or tools. They are in general more concrete and therefore the user needs a deeper understanding of the system. This paper in contrast presents a continuous concept to raise the abstraction level and include runtime control and monitoring into component-based models. The concept is based on an extended component-based meta model and libraries, which describe present components as well as their interfaces and parameters. During design time, based to the model designed by the user, source code is generated. At runtime, control commands are send to the embedded target according to user modification in the model as well as acquired monitoring data is back annotated and displayed on model level. The concept is demonstrated and evaluated using a reconfigurable hardware platform.
