  • Field Details

    • FLD_MAP

      public static final ScadaFieldMap FLD_MAP
      Map of field names to SCADA field Descriptors

    • delay

      @Field(type=double.class, ctrl=true, hndRb="TrgCfgDelayRb", hndSet="TrgCfgDelaySet") public double delay
      Time delay between beam-on event and actual DAQ start. NOTE: this value may be negative indicating DAQ before the beam-on event (thus, sampling only noise)

    • event

      @Field(type=int.class, ctrl=true, hndRb="TrgCfgTrigEventRb", hndSet="TrgCfgTrigEventSet") public int event
      Event code to trigger data acquisition - values 0,...,256

  • Constructor Details

    • TrgConfig

      public TrgConfig()
      Create a new, uninitialized DaqConfig object.

    • TrgConfig

      public TrgConfig(DataAdaptor daptSrc)
      Create a new TrgConfig object initialized from the given data source.
      Parameters:
