5. Sezione di Bari September 16, 2002D. Elia - DCS workshop / ALICE week 5 Steps towards prototype II 1.Design of the new VR board: full set of LV supplies for 1 half-stave (7 voltage regulators) fine tuning of VRs output via on-board DACs output voltages and currents available via on-board ADCs control logic implemented via on-board FPGA control operations by JTAG 2.Implementation of the supervisory control (PVSS): control of HV/LV supplies via PVSS link of PVSS to JTAG controller full integration of HV/LV/VR-boards

6. Sezione di Bari September 16, 2002D. Elia - DCS workshop / ALICE week 6 Long term planning (1) 1.FEE: - definition of Pilot Data frame - definition of DCS part of Router module - definition of interface between Router and ALICE-DCS - prototype chains for I,V monitoring - tests of Analog Pilot (I,V,T) and Digital Pilot - prototype of full FEE monitoring chain with Router 2.Interlocks: - definition of interlock strategy - tests with Analog Pilot - design of interlock box - integration with ALICE Safety System - full working prototype ( In collaboration with P. Chochula )

7. Sezione di Bari September 16, 2002D. Elia - DCS workshop / ALICE week 7 Long term planning (2) 3.Power suppies and VR: - tests and choice of HV/LV PS - prototype of VR board - interface between VR and DCS - integration with interlock and FEE monitoring system 4.Temperature monitoring: - prototype with PT1000 daisy-chain - choice of sensors - design of dedicated bus - test with Analog Pilot - interfacing with DCS 5.Database, 6.
