Kay Kasemir, Matthias Clausen, SNS,DESY EcliseCon March 2008 XFEL The European X-Ray Laser Project X-Ray Free-Electron Laser 9 CSS @ SLAC Met with Ernest, Sergei, Paul Chu, Greg White Ernest –uses CSS PV Tree for debugging, –plans to use Data Browser. High-level apps group –spent recent years on Matlab due to time constraints –"SEAL" concept for XAL & SLAC logic in Eclipse GUI –developed Eclipse CM Log viewer –working on XAL model server configuration for SLAC –Commonly accepted direction unclear

10. Kay Kasemir, Matthias Clausen, SNS,DESY EcliseCon March 2008 XFEL The European X-Ray Laser Project X-Ray Free-Electron Laser 10 CSS @ DESY Met with Matthias Clausen (DESY) On track to use CSS Synoptic Display with XFEL (end of '08) Meanwhile, alarm system in production for HERA Cryo Ctrl. –Beginning to link ~500 SDS displays, auto-converted from dm2k, as "detail" views from alarms. Working on SNL Editor and Debugger

11. Kay Kasemir, Matthias Clausen, SNS,DESY EcliseCon March 2008 XFEL The European X-Ray Laser Project X-Ray Free-Electron Laser 11 Synoptic Display Very good editor –Align, snap, grid, ruler –Configure color etc. of multiple selection –Layer support –Easy connection to CVS Everything dynamic and configurable –Link PV to text, color, position –Add multiple actions to any widget: open display, send value –Arbitrary tool-tip: PV Name, value(s!), user guidance

12. Kay Kasemir, Matthias Clausen, SNS,DESY EcliseCon March 2008 XFEL The European X-Ray Laser Project X-Ray Free-Electron Laser 12 Conclusion by Kay Need to create demo/test setup of alarm system (a bit more involved) Need to try synoptic display (volunteers?). Determine what's missing, broken, or needs adjustment.
