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

GUIs for FOPI

FOPI Main Panel RPC CDC Helitron statistic values • 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 channel address of LED colour coding informs user about channel's state shown by tip of LED • set all CAEN HV channels panel selection • display error history

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

Sector Panel for CAEN HV channels - 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 selection for sub detectors double click plot to open channel panel

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 • 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 • Online - Trending of temperature values measured by PT 100 • displays alarm state • variable update rate

Lambda - Low Voltage devices Fopi dedicated Mainpanel • control of up to 5 Lambda – Genesys • devices via GPIB bus • supplies RPC detector • use of the device - specific drivers • possibility to auto - write all channels, • archives voltage and current into a logfile ©A. Schwinn

Le Croy HV devices • old hardware (1985) • control via ESONE Server on a CAMAC Bus • very slow reaction time • output is written in output buffer of the 2132 Interface • device language is 16 Bitcoded and cryptic • control of more than 1700 HV - Channels • supply for photo - multiplier ©A. Schwinn

Constant Fractions • control of ca. 150 Constant Fraction "CF 8101" Discriminators • control via ESONE Server on a CAMAC Bus • CNAF´s are the CAMAC data words (Crate, Board, Address, Function) • able to observe all values, and to recognize changes • Enable/Disable boards to observe • able to play a alarm-wav file on alarm ©A.

Client – Server communication server client

Detector Hierarchy 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 fixed detector layer variable x/y/z: any crate/board/channel number, depending on how many HV channels are used channel layer

Sub Detectors server client filter Channels and User. List for sub detectors information concerning the joining sectors (upper & lower layer) is needed

Panel Behaviour client

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