  1. Epics Archiving at DESY Albert Kagarmanov (IHEP Protvino Russia) Matthias Clausen (DESY Hamburg Germany)

  2. Contents • DESY Epics Archiving overview • History • Using Channel Archiver experience • Current Work around Archiving • AAPI as Abstract Archive Data Interface • 2D waveform plot in Channel Archiver Web-Interface BESSY 2002, EPICS Workshop, Albert Kagarmanov “Epics Archiving at DESY”

  3. DESY Epics Archiving overview • History • A lot of different Control Systems at DESY • TINE for Hera, DOOCS for TTF, EPICS for Kryo • From 96 to 99 we are used used home-made Archive Monitor: • Filename Structure- yyyy/mm/recordName –1 file per month per record • Contents– simple binary array of time/value/status • Now this data convert to SDDS-format. • GUI- IDL tool from Research Systems,Inc (http://www.rsinc.com) -see following picture: BESSY 2002, EPICS Workshop, Albert Kagarmanov “Epics Archiving at DESY”

  4. Typical IDL screens: BESSY 2002, EPICS Workshop, Albert Kagarmanov “Epics Archiving at DESY”

  5. DESY Epics Archiving overview • Using Channel Archiver Experience • We are using Channel Archiver during last 2,5 years. • Currently we are storing about 3000 channels. • It’s working good. We had some troubles with writing data to NFS-disk. • GUI for Archive Data: • Standard CGI-interface from Channel Archiver • IDL • Strip(History)Tool • JoiMint through DIXI-server for XML-data BESSY 2002, EPICS Workshop, Albert Kagarmanov “Epics Archiving at DESY”

  6. Current Work around Archiving • AAPI as Abstract Archive Data Interface • For extract data from different Archive Source (EPICS,DOOCS,TINE,SDDS) we are using additional program interface layer : Archive API - AAPI • AAPI can answer for few questions about abstract archive data: • getData [and ControlInfo] • getChannelInfo • getChannelList • AAPI is independent TCP/IP server • AAPI_server –port 3999 & BESSY 2002, EPICS Workshop, Albert Kagarmanov “Epics Archiving at DESY”

  7. Current Work around Archiving • AAPI as Abstract Archive Data Interface • Name convention: by prefix: • EPICS|channelName (Epics is default) • DOOCS|channelName • TINE|channelName • (plan?) OLD_EPICS|channelName ( For old archive data) • AAPI is more convenient for adding new Data Source: • Do not need recompile existing GUI application • Do not need even restart it. (See next picture: ) BESSY 2002, EPICS Workshop, Albert Kagarmanov “Epics Archiving at DESY”

  8. AAPI as Abstract Archive Data Interface Channel Archiver SDDS Epics Data Other/Old Epics Data HERA TINE TTF DOOCS • Blue lines – not implemented yet. ArchiveAPI -interface Other Control System DIXI / XML Perl/Other CGI-interface StripHistory Tool IDL JoiMint Other GUI EPICS World BESSY 2002, EPICS Workshop, Albert Kagarmanov “Epics Archiving at DESY”

  9. 2D waveform plot in Channel Archiver Web-Interface • 2D waveform plot in Channel Archiver Web-Interface : • Existing 3-D waveform picture is very complicate for understanding. • For improving this situation we are added small modification to existing CGI-Web part of Channel Archiver. • We are added additional button “2D-Plot” and textEntry “wf number”, which allow 2d-plot this waveform as 2D-picture: BESSY 2002, EPICS Workshop, Albert Kagarmanov “Epics Archiving at DESY”

  10. 2D waveform plot in Channel Archiver Web-Interface BESSY 2002, EPICS Workshop, Albert Kagarmanov “Epics Archiving at DESY”

  11. 2D waveform plot in Channel Archiver Web-Interface • 2D picture for time = 05/05/2002 00:38:17 , Number =3. • Link: http://www-kryo.desy.de/documents/2dPlot.html BESSY 2002, EPICS Workshop, Albert Kagarmanov “Epics Archiving at DESY”
