The control and data acquisition system (CODAC system) for the fusion experiment Wendelstein 7-X is designed for miscellaneous operational scenarios: short pulses with arbitrary intervals, steady-state long pulse operation and arbitrary sequences of short phases with different characteristics in one discharge. The data structures for a description of experiment runs are very complex and comprehensive. A special editor is necessary to guide the user through the different phases of experiment program planning. A more abstract and physics-oriented description of the required machine and plasma behaviour is a suitable way to handle the complexity and to make the experiment program definition process effective and easier.
