  1. Control and Monitoring of PID Detectors Jean-Sebastien Graulich, Geneva • Disclaimer • Remarks on Control and Monitoring: 1) Missions 2) Settings and Variables 3) The Finite State Machine Approach • PID C&M Logical Description • The ideal GUI • Summary Jean-Sébastien Graulich

  2. Disclaimer • Control and Monitoring of one detector should be under the responsibility of the group building the detector… • I have no experience in developing C&M systems • No concrete activity is possible before the hardware is chosen • In particular, the HV system is not defined yet for TOF, CKOV and EMCAL ! Jean-Sébastien Graulich

  3. Remarks on C&M • My understanding of Control: • Set all the parameters required for the experiment to run in a given configuration • What to do in case of *Event* The Event can be anything between “Voltage of Channel X is 1V above the nominal value” to “the physicist wants to start data taking” Monitoring: • What is the state of a Subsystem at a given time (could be now) This implies the knowledge of all the values of variables and settings Jean-Sébastien Graulich

  4. PID Settings and Variables • HV Settings (usual ones, may change when the HV system is chosen): • HV Set Point MICE-DET-HVPS-01:001:HVSP • Range Level 1 (Dead band) MICE-DET-HVPS-01:001:RL1 • Range Level 2 (Warning Level) MICE-DET-HVPS-01:001:RL2 • Range Level 3 (Alarm Level) MICE-DET-HVPS-01:001:RL2 • Imax L0 MICE-DET-HVPS-01:001:IMX0 • Imax L1 • Trip Time MICE-DET-HVPS-01:001:TRPT • Ramping Up Parameter MICE-DET-HVPS-01:001:RUP • Ramping Down Parameter MICE-DET-HVPS-01:001:RDP • HV Variables: • Actual Voltage MICE-DET-HVPS-01:001:HVV • Actual Current MICE-DET-HVPS-01:001:IV • Status (Normal, Tripped, MICE-DET-HVPS-01:001:STARamping up, Ramping Down) • Other Variables: • Hall Temperature (for TOF) • VME crate Status X 110 for TOF X 240 for EMCAL X ? For CKOV Define when the channel will be switched off automatically Idem Jean-Sébastien Graulich

  5. PID C&M Logical Description • Object: TOF_HV (the group of all the TOF_HV_CH) • State: ALL_ACTIVE (All channels are ON, none is INACTIVE) • State: PART_ON (Some Channels are ON but not all of them) • State: OFF (All channels are OFF) • State: OUT_OF_RANGE_L1 (idem for OUT_OF_RANGE_L2 and OUT_OF_RANGE_L3) (Some channels are in OVERFLOW_L* or UNDERFLOW_L*) • State: TRIPPED (Some channels are TRIPPED) • State: UPDATING (Some channels are UPDATING) • State: COM_ERROR (Some channels are in COM_ERROR) Jean-Sébastien Graulich

  6. USC DSC EMCAL • The Ideal GUI TOF2 TOF0 TOF1 Tracker 2 Tracker 1 • Each Detector has a color:Green= FULL_READY Yellow= OUT_OF_RANGE_L2 Red= OUT_OF_RANGE_L3 or TRIPPED or NOT_READY White= INACTIVE • Each Detector is clickable, a panel pops up with the status of each individual channel • The same panel can be used to edit the settings, providing a password Jean-Sébastien Graulich

  7. Summary • PID Control is basically limited to the Control of HV Channels • 110 Channels for TOF • 240 Channels for EMCAL • A few Channels for CKOV • Time to think about User requirement for the Detector C&M GUI • And also to assign this task to someone… Jean-Sébastien Graulich
