requirements for FOPI control systemrequirements 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

colour coding of LED

channel address of LEDshown 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

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

Trend, Alarm & Temperature Trend, Alarm & Temperature MonitorsMonitors

• 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 oftemperature values

measured by PT 100• displays alarm state• variable update rate

• displays all occured alarms access to alarm data of DSC database viaDSCAlarm class

• displays alarm settings• unacknowledged alarms• generates alarm

documentation file• alarm summary

Lambda - Low Voltage devicesLambda - Low Voltage devicesFopi 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

Le Croy HV devicesLe 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 Bit-coded and cryptic

• control of more than 1700 HV - Channels

• supply for photo - multiplier

Constant FractionsConstant 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

variable

m: number of sub detectors in HEL_nn: number of sub detectors in HELs: lowest layer of CDC

e.g. s = 0_0_0 depth = 5t: 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

CSCS requirements requirements

problem: DB entry with different parameters for each detector object ( fixed hierarchy)

solutions: a.) optional "data - in" parameter for "load process" – eventb.) 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“
