  1. OPC servers news S.Popescu CERN PH/AIT Alice DCS workshop, Geneva S.Popescu

  2. 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 Alice DCS workshop, Geneva S.Popescu

  3. OPC server news (2) 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 Wiener Maraton RCM front view Alice DCS workshop, Geneva S.Popescu

  4. OPC server news (3) 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

  5. 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 Alice DCS workshop, Geneva S.Popescu

  6. OPC server news (4) 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

  7. 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

  8. 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 Alice DCS workshop, Geneva S.Popescu

  9. Display of 4 channel stability over 2 hours  measurements showed 0.01 V stability over time and dynamic load Alice DCS workshop, Geneva S.Popescu

  10. Conclusions • 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) Alice DCS workshop, Geneva S.Popescu
