A concept of online monitoring for the Wendelstein 7-X experiment

Steady state operation of the Wendelstein 7-X fusion experiment makes it indispensable to visualize a representative portion of the measured data online. A three tier concept for online data monitoring is introduced and focused upon four main points:• neration of representative raw monitoring data within a data acquisition tier without disturbing the data acquisition line analysis of all raw monitoring data by a monitor server tier including the synchronization of data from different sources sualization of the monitoring data by a monitor client tier for local and remote participation mmunication between the participating tiers rrent prototypic implementation is presented and the techniques used as well as the benefits achieved are discussed.
