      • Control software v2.1
    • The prototype was used for first tests of the EHQ module.
    • The behavior of the module for different operational modes has been analyzed .
  • 3) FSM (Finite State Machine) prototype
    • It was foreseen the possibility of operatingsingle channels or groups of channels
    • It was simulated the connection with a database, loading parameters or writing to database
    • FSM prototype was built as a first test
    • It was operated with 16 channels connected to the hardware and 69 channels were simulated

Temperature monitoring prototype

TPC stringent requirement = 0.1 oC stability  a reading resolution of ~ 0.04 oC

Two hardware solutions were tested:

Wago mPLC industrial product

ELMB (Embedded Local Monitor Box) developed by ATLAS

Comparison test made ELMB chosen for the following reasons:

Results:

    • High Voltage:
    • The good news is that the delivered voltages remain unaffected by any communication failures, power cuts etc..
    • The software controlled settings correspond to the true physical values (no local display available on crate or module)
  • Low Voltage:
  • PS behavior with SLIC.OPC (custom solution) regarding local setting ok
    • Main constrains :
    • Company (Wiener) OPC server not available yet
    • Control of single channels (On/OFF, Error Clearing, Reset…) for the PL500 not possible

  • Results:
  • heat transfer from FEC cards to pad plane ~ 0.18 0C
  • relaxation time is approximately 30 minutes
  • Further investigations need to be done for regulations
  • studies
