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”.
