7. slide 718 th DCS Workshop – March, 6Francesca Poggio detector DCS FSM and other news… basic version of the top level: not existing PVSS version in use: 3.6 detector installation foreseen for mid-May (changed with respect to the DCS commissioning meeting…) –considering the new instalation date, the hand-over of the project is shifted to May we are in contact with offline experts, we are trying to speak the same language…

8. slide 818 th DCS Workshop – March, 6Francesca Poggio final installation at Point 2 PC: ok cables: interlocks for the positioning system (not under our responsibility) HV: available, but no urgent need to install them, they will be installed when it will be clear that we can also monitor them… VME: same as HV PLC: after surface test with PVSS Integration with other online systems: test at Point 2 with DAQ and TRG, not before end june
