Interruptions
Interruptions

  • Dec.7-> Feb. 4: No access to Controls System from Outside, Except for approved personnel.

    • E-mail me with names who need access. I can always add people later.

  • Jan. 12->21 Point 2 shutdown for major cooling intervention. No power to racks, ACR’s,…

  • DAQ upgrade to SL5 not scheduled yet (no testing).

    • Need to test all Shuttle programs (calibration…)

    • New DAQ hardware will be 64 bit machines.

    • DCS remaining on SL4, XP, 2003. Only new machines will be 64 bit.

  • Central DCS plan Hardware/Software upgrades.

    • All XP system must upgrade to SP3.

    • PVSS and JCOP patched introduced as needed.

    • Direct RDB queries to be implemented, 5 min/system

Hardware items
Hardware Items

  • Request to send in all ISEG create for modifications

    • Add externally controllable slow ramp-down of HV.

    • Can be used in case of loss of communications with control system.

    • Can be wired into EMCAL’s “Emergency Stop” button. Sets EMCAL into “Supper-Safe” mode.

  • A new round of cable installation is planned. Do we have any new cable to be installed?

  • Ethernet outlets are in low supply do we need more?

  • Now is the time to request any Rack modifications..

Points to consider
Points to Consider

  • Implementation of a new ALICE State, “Run Pause”

    • If a detector has a problem, in stead of Stopping and starting a run, that detector can request a “Run Pause”. All other detectors stay in usual state ready to pick up the run.

    • Might the EMCAL want to do so?

    • What might the EMCAL want to do if some one else request a “Run pause”?

    • This might/will have an effect on Shuttle programs which will need to exclude this paused time period during its calibrations (especially if they were the cause of the pause).

    • Any Other issues/requests???

  • Large power perturbations have been seen by ALICE.

    • What do we know about EMCAL’s behavior during these times?

    • Do we have system working to handle such problems?

    • Especially during installation phase, can we handle unexpected interruptions “any were”?

    • We may want to set up tests of some or all of our interlocks and monitoring system.

Dcs plans changes
DCS plans/changes

  • Implement new EMCAL hardware

  • Remove some Data-Points queried from other systems, others to get “centralized”.

  • Fully Backup our system.

  • Write Restore instruction and provide information about any private/special code needed.

  • Implement RDB monitoring (add one data point).

  • Implement Alert/Alarm help for Central DCS and EMCAL DCS system.

  • Administrator Access to DCS machines.

    • Recently, Federico had to reboot the DCS machines.

    • Clearly all On-call’s need this privilege.

    • It can easily be granted on request, or do find some other solution?

Background c hanges
Background Changes

  • We will no longer use PVSS. Now it is called “SimaticWinCC”.

  • New DCS data base to be installed.

  • DB table size to be significantly reduced in size.

  • A review of the ALICE Safety Matrix.

    • EMCAL always “SAFE” and “Supper Safe”.
