Downtimeless evolution of distributed automation systems (changes during runtime) sets high demands on the underlying concepts and methodologies. Within the εCEDAC project a sophisticated description of the underlying system, including state information as well as capabilities of the hardware, is used. In combination with an engineering tool it offers a great amount of engineering support, thus keeping the complexity manageable. This paper illustrates the application of this technology especially for evolution engineering. Herein, the εCEDAC approach provides a mean for checking the correctness of the process of downtimeless evolution by use of a reconfiguration application.
