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.
