This VariableType defines the general characteristics of a DataItem. All other DataItem Types derive from it. It defines the optional properties Definition and ValuePrecision. The DataItemType derives from the BaseDataVariableType.
Definition is a vendor-specific, human readable string that specifies how the value of this DataItem is calculated. Definition is non-localized and will often contain an equation that can be parsed by certain clients. Example: Definition::="(TempA - 25) + TempB"
ValuePrecision specifies the maximum precision that the server can maintain for the item based on restrictions in the target environment.
ValuePrecision can be used for the following DataTypes:
The ValuePrecision Property is an approximation that is intended to provide guidance to a Client. A Server is expected to silently round any value with more precision that it supports. This implies that a Client may encounter cases where the value read back from a Server differs from the value that it wrote to the Server. This difference shall be no more than the difference suggested by this Property.
