Integrated commissioning of ECRH for W7-X

The W7-X start-up scheduled for 2015 demands a lot of integrated tests at all auxiliaries as well as the ECRH installation in order to ensure a reliable interaction. Up to 10 gyrotrons have to be controlled as well as 10 different wave guides and two additional remote steering launchers apart from the 10 ordinary front steering launchers. The ECRH remote control system has to be connected to the central W7-X control system in a reliable and easily maintainable way. The main challenges and developed solutions will be discussed.
