Ecal prototype dcs system using pvss

Contents:

  • Proposed layout of the DCS

  • SM0 and SM1 layouts

  • Status of implemented sub-systems

  • Conclusions

8.7.2003


Proposed layout

Proposed layout


Proposed layout1

Proposed layout

  • Separate into 4 sections of sub-detector:

    EBL,EBR, EEA,EEB

  • Each section has same structure

  • 7 sub-systems:

    HV, LV, Cooling, Precision Temp,

    Humidity, Laser Monitoring, TSS

  • Communication to DSS, DAQ and CMS central DCS


Sm0 and sm1 layouts

Status of implemented sub systems

Status of implemented sub-systems

  • DSS monitors the PLCs of the TSS

  • Internal structure reflecting that of the figure

  • All testbeam data sent to Oracle devdb. Easy to retrieve data to text files

  • Only systems not implemented: Laser monitoring and LV


Supervisory system

Supervisory System:

  • Based on FwFSM, Finite State Machine, sends commands, receives states

  • As a separate PVSS system

  • Will communicate with all other systems

  • Implemented into the Hierarchy (FSM) so far for Cooling and HV systems. Others to follow....


Supervisory system1

Supervisory System:


Status of implemented sub systems1

Status of implemented sub-systems

Cooling system:

  • Ready for testing

  • Only sends states, does not receive commands, passive monitoring.

  • Calibration coefficients and limits can be changed from PVSS with a password.

Status of implemented sub systems2

Status of implemented sub-systems

HV:

  • installed on final PC, long term stability tests started

  • Need a password to change any settings and turn on/off channels.

    Precision Temp:

  • development started: SM0 will have 2 parallel systems: 1 using ELMB, other using Keithley

Precision Temp main panel:

PROTOTYPE ONLY: for the Keithley system!


Status of implemented sub systems3

Status of implemented sub-systems

Humidity:

  • System similar to the Precision Temp, to be implemented

    TSS:

  • Implemented by the Belgrade group

  • Being tested at the moment


Status of implemented sub systems4

Status of implemented sub-systems

Communication with DAQ:

  • Done via an XML file read by a C++ proxy. Communication to PVSS via DIM.

    (note: not the final system, only for SM0, until the XDAQ system implemented)


Status of implemented sub systems5

Status of implemented sub-systems

  • LV communication to be defined before a PVSS development can start

  • Possibility of web-enabling the Oracle database to allow everyone access to the data in the tables


Conclusions

Conclusions

  • Close to achieve a nearly “complete” PVSS-controlled DCS for SM0 and SM1

  • Aim for a complete control by the fwFSM system

  • SM0 first large scale test for ECAL-DCS

  • SM0/1 systems as “prototype” for complete ECAL

  • The feedback from the shifters during the first weeks of SM0 will be very important
