The following Properties are defined to extend the AnalogItemType.
The Variable DisplayFormat specifies how the value shall be displayed across all displays, clients and applications for uniformity. It is a string that contains one or more format specifiers, which are single characters or groups of characters that define how the string representation of that object’s value should appear.
The Variable EffectivePrecision specifies the significant part of the value, e.g. 0.01 means 1% precision.
The Variable HH identifies a high limit for the variable above which an event is triggered.
The Variable H identifies a high limit for the variable during normal process.
The Variable L identifies a low limit for the variable during normal process.
The Variable LL identifies a low limit for the variable below which an event is triggered.
The Variable AnalogMeasurement represents the current value measured by the sensor.
The Property EngineeringUnits specifies the units for the AnalogMeasurement’s value (e.g., DEGC, hertz, seconds). The EUInformation type is specified in 5.6.3 OPC 10000-8.
The Object UIInfo contains graphical specifications required for creating faceplates to display information about the containing object.
