Lambda, low-Voltage device … GPIB CAEN - HV 70 Channels LeCroy – HV 1792 Channels CS -Interface Objekte CAMAC PT100 ca. 200Stck.

3. requirements for FOPI control system - remote control and monitoring of power supplies (High/Low Voltage) - archiving of measured values (voltage, currents, temperatures) - archiving of hardware configuration/settings (ramp / trip time, set points) - distributed control system (Front End / Operator)  independant Front End - User Management: several profiles  access rights - possibility to divide High Voltage channels into sectors (RPC/CDC/Helitron) - internal errors should be displayed for the user - controlled and variable boot sequence

4. GUIs for FOPI

5. FOPI Main Panel colour coding of LED channel address of LED shown by tip statistic values panel selection cross – section of the detector's drift chambers (CDC/RPC/Helitron) mapping of CAEN HV channels  allocation between channels and sectors statistic values for each sector panel selection allows user to open other panels colour coding of LED informs user about channel's state set all CAEN HV channels display error history RPCCDC Helitron

6. CAEN Power Supplies 1527 & PT 100 sensors channel state channel output password request temperature of PT 100 sensor detailled configuration Board Information supplies RPC, CDC and Helitron access via CAEN OPC server and LabVIEW DSC Module structure: crates/boards/channels one PT 100 for each HV channel user management by password request (2 user profiles: admin/user) additional board information online trending for output values background colour indicates sector area only visible after logged in successfully area only visible after push Board Info

7. Sector Panel for CAEN HV channels double click plot to open channel panel selection for sub detectors - background colour indicates sector membership - allows user to open sub sector panels - set all channels mapped to sector - error history - colour of plot indicates alarm state

8. Trend, Alarm & Temperature Monitors displays trendings of measured and configuration values  access to log data of DSC database via DSCTrend class editable time interval for trendings error display divides High Voltage channels by sectors Online - Trending of temperature values measured by PT 100 displays alarm state variable update rate displays all occured alarms  access to alarm data of DSC database via DSCAlarm class displays alarm settings unacknowledged alarms generates alarm documentation file alarm summary

15. Detector Hierarchy channel layer detector layer fixed variable m:number of sub detectors in HEL_n n:number of sub detectors in HEL s:lowest layer of CDC e.g. s = 0_0_0  depth = 5 t:number of sub detectors e.g. in lowest layer of CDC_0_0_0 x/y/z:any crate/board/channel number, depending on how many HV channels are used

16. Sub Detectors serverclient filter Channels and UserList for sub detectors  information concerning the joining sectors (upper & lower layer) is needed

17. Panel Behaviour client

18. CS requirements problem:DB entry with different parameters for each detector object (  fixed hierarchy) solutions:a.)optional "data - in" parameter for "load process" – event b.)class to create user- defined database entries by event problem:DB entry for each channel object required (  truncate name.vi) solution:template DB entry as default for an object inherited by BaseProcess  additional parameter for load – process, e.g. „use default DB entry“ or „use database entry from instance“
