  1. DESY Strip Tool extensions Matthias Clausen Albert Kagarmanov MKS-2, DESY

  2. New features: • History specific features: • Why history feature? Realization scheme. • History Algorithms Menu • Circle Fitting. Redraw • Our realizations (History Record, calls to archive) • Common features: • Y-scale Zoom and Moving • Current Value Showing • Logarithm Scale • Auto range • Conclusions, TODO, download.

  3. Why history feature? • Operators want to have 1-2hour previous data when they start StripTool • “Close” problem: If someone will close StripTool all data tracks will lost. • Historical reason: No good/fast archive browsers. • DESY specific reason: Data for 1996-2000 years was saved in “home made” bin/SDDS-format. • Some info you can find under : www-kryo.desy.de/main/tools.html

  4. Realization scheme: • Current data coming from CA (original StripTool) • History data coming from “archives” • 2 way for archive call: • 1) Local (LibIO, SDDS) • 2)Network (Archive API ) • Both case are implemented as compiler option • Current DESY realization use AAPI.

  5. History Window

  6. Reduction method: Average • Average method: useful for common view, using like default (Can’t show single min/max)

  7. Reduction method: Tail of raw • History Panel: Last 1024 real points from archiver

  8. Reduction method: Sharp • Sharp Method will try keep all essential min/max

  9. Reduction method: Spline • Spline: use well known cubic spline interpolations

  10. Endpoints • Allows exactly set time-scale endpoints

  11. Show points • Show points like small circle

  12. Redraw • 12 month • plotting • 1 day • plotting • after • replot

  13. Common View: Y scale moving, current Value

  14. Logarithm scale • Logarithm Scale is important for value as a pressure.

  15. Auto range

  16. DESY realizations: • In StripTool 2.4b8 from JLAB was added StripHistory_fetch() call, so all WS-Developer can create history browser using his own local archiver. For example, in LANL ChannelArchiver support was added into StripTool • At DESY we are using history record from IOC first (usually in this record have about 200 more recent history points ) and if we need more points we get data from our SDDS-binary files (AAPI protocol) • Request for history record - channel access call . • Request for archiver – AAPI(over TCP/IP) call to AAPI server which extract data from SDDS-files.

  17. DESY realizations: • Get Data Request • First current data • Need more data? Try Archive Record (CA) • Need more ? Try ask AAPI (TCP/IP)

  18. Conclusions, TODO, download. • StripTool with History extensions seems more flexible (real Data Browser). • TODO: • C++ version of StripTool (Chris Larrieu) • Min/Max curves? • Download: Current version of Strip(History)Tool available under ftp://ftp.desy.de/pub/EPICS/extensions/ 1) stripHistoryTool/StripHistoryAtDESY.tar.gz 2) AAPI/AAPIatDESY.tar.gz
