14. Conclusions XM is the central platform to operate ASDEX Upgrade and automate experiment execution. It -defines operation methods of the machine -provides acces methods to resource information and monitors resources -provides central services for configuration, logging, protocolling, and archiving -provides user interfaces for operators / sys.engineers / exp.leaders The separation of operation control flow from discharge information handling helped to design a method to configure the highly flexible system in a transparent way.
