This VariableType defines the general characteristics of an AnalogItem.
The AnalogItemType derives from the BaseAnalogType.
The StatusCode delivered with the value also contains an informational bit called SemanticsChanged. Servers that implement Data Access shall set this Bit in notifications if EURange (could change the behaviour of a Subscription if a PercentDeadband filter is used) or EngineeringUnits (could create problems if the client uses the value to perform calculations) Properties are changed. Clients that use any of these Properties should re-read them before they process the data value.
In addition a server can send SemanticChangeEvents if the value of the properties EURange and EngineeringUnits are changed. To indicate this capability, the SemanticChange flag must be set in the AccessLevel and UserAccessLevel attributes of this variable.
