ZeroPointAdjustment: ABN614#002 defines property that initiates when set the TRUE (ON) state a procedure, which maybe automatic, to define or set the value zero of the output. Remark: properties can be variables or methods according to IEC 61987 CDD.
AnalogSignal provides the measured or readback process value. The unit of this value is provided by the EngineeringUnits property.
<SignalCalibrationIdentifier> is a container object for the calibration parameters of the signal. It has an interface reference to ICalibrationType in order to add general calibration variables. Since it is a placeholder, an instance of AnalogSignalType can have several calibration objects.
SignalConditionSet is a container object for the condition parameters of the signal.
The components of AnalogSignalType have additional references which are defined in Table 151.
