OPC server news (1)

CAEN power supplies (HV and LV)

  • OPC server free available for all their modules from

    http://www.caen.it/computing/scdown.php

    - Last OPC server version - 2.9 (march 2005)

  • supports Crates SY127, SY403, SY527,

    SY1527, SY2527

  • Easy 3000 (harsh environment) system included

  • Downloads from www.caen.it

  • Framework currently supports the following Easy boards:

    • LV: A3006,A3009,A3016,A3025,A3100, A3050

    • HV: A3506P/N, A3507P/N, A3512P/N, A3535P/N, A3540P/N

    • Mixed:A4601 H/F

Wiener Power supplies (LV only), Fan Trays and VME crates

  • OPC servers developed by the company (contact IT-CO )

    1.) CANBus OPC server - for remote control of VME PS UEP6021, PL500 family, “Maraton LV moderate HE” interface (KVASER)

    • KVASER PCI CAN drivers are used

      2.) TCP/IP OPC server – so far only for the VME compatible Remote Control Module (RCM) for ”Maraton LV hazardous HE”

    • arrived (version 1.0.0.0, 2 Oct 2005) and under test (IT-CO, M.Beharrell)

    • Documentation still to come

    • First connection to the controller indicates it is working

USB port

TCP/IP port

ELMB (Embedded Local Monitor Box)

  • CAN OPC server available by Atlas DCS group

  • CAN interface (N.I. NICAN driver, KVASER CANLIB driver)

  • Current free OPC version: CANopen OPC Server+ DA 2.5

  • http://atlas.web.cern.ch/Atlas/GROUPS/DAQTRIG/DCS/ELMB/DIST/ELMBdoc.html

  • Framework 2.3.3 fwELMB component available

  • OPC server working very well for temperature monitoring (PT100, PT1000 and NTC sensor

  • Also working also for B-field sensor – “simple version” (produced by NIKHEF)

    • “addressable version” needs a modification of the present OPC server

Alice DCS workshop, Geneva

S.Popescu


Example: ELMB B-Field readout

  • CANBus OPC server+ DA 2.5 for B-field sensor

    • Alice magnet field tests (July-Sept2005)

    • was stable

    • B-field readout via PVSSII software

The Bsensors “simple” versions installed inside

the Alice dipole magnet

OPC based On-line display of the dipole B field values

Iseg HV power supplies

  • OPC server available from Iseg

  • Free download from

    www.iseg-hv.de

  • CAN interface: PCI, USB (Peak company)

  • Last OPC version is 4.02

  • Framework fwIseg 2.0.3 is working with 4.02

  • A new version of fwIseg will be released in 2 weeks; will implement the alarm handling

  • OPC server is stable since Version 4.0; proven in the PHOS lab

Alice DCS workshop, Geneva

S.Popescu


Example:Iseg HV tests PHOS

  • Dynamic loads tested with quasi random ~1Hz 9mA

  • on/off switching in 8-channels

  • Over-current switch

PHOS Requirement

  • Groups of 448 APD channels alimented by 1 Iseg EQH channel of 380.0 V at an average current of 9 mA

  • Each single APD HV bias is controlled by 10 bit bias controller 240-380 V on FEE cards. Individual settings via DCS/RCU

  • Stability requirement is 0.1 Volt (3 * 10-4) over long time and short time dynamic load ( EM particle flux)

Testbox 8 HV channels

( Emulates 1 PHOS module)

Alice DCS workshop, Geneva

S.Popescu


Phos example continued on line trending of 4 hv iseg channels for different hv set points
PHOS example continued: On-line trending of 4 HV Iseg channels for different HV set-points

HV set values:

-Ramp up and down

-10V/s

~ 5 min from 240-400

S.Popescu


Display of 4 channel stability over 2 hours channels for different HV set-points measurements showed 0.01 V stability over time and dynamic load

Alice DCS workshop, Geneva

S.Popescu


Conclusions
Conclusions channels for different HV set-points

  • Functional and stable OPC servers available

  • CAEN OPC servers always up-to-date

  • Wiener to finalize release version

  • ELMB fully stable versions available

  • Iseg now stable (proven by PHOS test)
