Device Properties
Property name
Property type
Description
BPMManager Tango::DEV_STRING the BPMManager device name
BPMOrbitAttr Tango::DEV_STRING attribute to read on BPMManager to get the orbit
BPMRefOrbitAttr Tango::DEV_STRING attribute to read on BPMManager to get the reference orbit
DCCTCurrentAttr Tango::DEV_STRING attribute name for the current
DCCTDevice Tango::DEV_STRING DCCT device name
DCCTMinCurrent Tango::DEV_DOUBLE the minimal current, under which the feedback loop is stopped, in mA
DeltaRFMax Tango::DEV_DOUBLE If an iteration computes a delta value above DeltaRFMax, the feedback loop must be stopped.
DeltaRFMaxIteration Tango::DEV_DOUBLE Maximal RF frequency variation which will occur in one iteration. If the computed delta is above, it is thresholded to this value to smooth the RF frequency variation between several iterations.
DeltaRFMinIteration Tango::DEV_DOUBLE Minimal RF frequency variation which will occur in an iteration. If the computed delta is below, no correction is applied.
LockAttr Tango::DEV_STRING attribute name on the lock device
LockDevice Tango::DEV_STRING lock device name
MaxRFErrors Tango::DEV_LONG the maximum number of RF errors since the feedback loop began
RFDevice Tango::DEV_STRING device where the RF frequency is set
RFFrequencyAttr Tango::DEV_STRING attribute name for the frequency
SoundDevice Tango::DEV_STRING textalker device
SimulatedMode Tango::DEV_BOOLEAN if true, the writing of the RF frequency is skipped, but the rest of the algorithm runs as in normal mode. Also, no sound message are emitted
FeedbackPeriod Tango::DEV_DOUBLE The period at which the iterations are executed
DispersionFunction Array of double the dispersion function
ActivatedBPM Array of long the activated BPM ( 0 : inactive, 1 : active )
