  1. EMCalDCS and relatedIssues with Shutdown/Installation B. S. Nilsen M. Cherney J. Fujita

  2. 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 EMCal Weekly meeting Thursday November 11, 17:30 cern

  3. 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..

  4. 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.

  5. 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?

  6. 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”.
