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 LabVIEW DSC Module
Information
• structure: crates/boards/channels
• one PT 100 for each HV channel
• user management by password
channel output

admin/user)

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

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

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

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

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 BaseProcess
 additional parameter for load – process,
e.g. „use default DB entry“ or
„use database entry from instance“
