Data acquisition task • In the final stage there will be about 100 diagnostic systems • Collect data from the diagnostic hardware • Store and archive data for common access in time • Data should be stored in a global space • Data from all systems have to be comparable • Configuration for the system on a global scale • Handle data for long pulses 2. 3. 2005 P. Heimann, Design Review March 2005 3

Long pulses • Discharges up to 0. 5 h – new concept for data acquisition – new structure of archived data – segment concept • • Global time Data monitoring Remote control, automatic execution Message logging Data reduction Pattern recognition, event driven sampling Real time for feedback 2. 3. 2005 P. Heimann, Design Review March 2005 4

General requirements The system should be • • • Flexible Extendable Maintainable No early decision on computer hardware As far as possible independent of a special operating system As far as possible use mainstream hardware components and software Use already proven concepts from existing systems Modern software design principles, Object oriented methods Object oriented data base Java as implementation language 2. 3. 2005 P.
