The BaseVariableType is the abstract base type for all other variable types.
However, only the PropertyType and the BaseDataVariableType directly inherit from this type.
There are no references, except for HasSubtype references, specified for this variable type.

This VariableType is used as the type definition whenever there is a DataVariable having no more concrete type definition available.
This VariableType is the base VariableType for VariableTypes of DataVariables, and all other VariableTypes of DataVariables shall either directly or indirectly inherit from it. However, it might not be possible for Servers to provide all HasSubtype References from this VariableType to its subtypes, and therefore it is not required to provide this information. The BaseDataVariableType is a subtype of the BaseVariableType.
There are no References except for HasSubtype References specified for this VariableType.

HasSupertype | VariableType | BaseVariableType |
This VariableType is used as the type definition for all Properties.
Properties are defined by their BrowseName and therefore they do not need a specialised type definition. It is not allowed to subtype this VariableType. The PropertyType is a subtype of the BaseVariableType.
There are no References specified for this VariableType.

HasProperty | Variable | DataTypeVersion | String | Scalar | PropertyType | Optional |
HasProperty | Variable | DictionaryFragment | ByteString | Scalar | PropertyType | Optional |
Used as the type for the DataTypeDescriptions.
There are no References specified for this VariableType. It defines the optional properties DataTypeVersion and DictionaryFragment.
DataTypeVersion indicates whether the type description of the DataType has changed. Changes to the DataTypeVersion may impact the operation of Subscriptions. If the DataTypeVersion changes for a Variable that is being monitored for a Subscription and that uses this DataTypeDescription, then the next data change Notification sent for the Variable will contain a status that indicates the change in the DataTypeDescription.
In some scenarios an OPC UA Server may have resource limitations which make it impractical to expose large DataTypeDictionaries. In these scenarios the Server may be able to provide access to descriptions for individual DataTypes even if the entire dictionary cannot be read. For this reason, this standard defines a Property for the DataTypeDescription called DictionaryFragment. This Property is a ByteString that contains a subset of the DataTypeDictionary which describes the format of the DataType associated with the DataTypeDescription. Thus, the Server splits the large DataTypeDictionary into several small parts and Clients can access without affecting the overall system performance.

HasProperty | Variable | NamespaceUri | String | Scalar | PropertyType | Optional |
This VariableType is used as the type for the DataTypeDictionaries.
There are no References specified for this VariableType. It defines the optional properties DataTypeVersion and NamespaceUri.
Changes in DataTypeDictionaries may be a result of a change to a type description, but it is more likely that dictionary changes are a result of the addition or deletion of type descriptions. This includes changes made while the Server is offline so that the new version is available when the Server restarts. Clients may subscribe to the DataTypeVersion Property to determine if the DataTypeDictionary has changed since it was last read.
Clients may subscribe to the DataTypeVersion Property to determine if the DataTypeDictionary has changed since it was last read.
The URI for the namespace described by the Value Attribute of the DataTypeDictionary.

The base VariableType for Variables that store a Transition that occurred within a StateMachine as a human readable name.
The SourceTimestamp for the value specifies when the Transition occurred. This value may also be exposed with the TransitionTime Property.
A name which uniquely identifies a Transition within the StateMachineType.
A subtype may restrict the DataType.
A QualifiedName which uniquely identifies a transition within the StateMachineType.
An integer which uniquely identifies a transition within the StateMachineType.
Specifies when the transition occurred.
Specifies the time when the current state or one of its substates was entered.
If, for example, a StateA is active and – while active – switches several times between its substates SubA and SubB, then the TransitionTime stays at the point in time where StateA became active whereas the EffectiveTransitionTime changes with each change of a substate.

HasProperty | Variable | BitMask | Boolean | OneDimension | PropertyType | Optional |
HasProperty | Variable | OptionSetValues | LocalizedText | OneDimension | PropertyType | Mandatory |
This VariableType is used to represent a bit mask.
Each array element of the OptionSetValues Property contains either the human-readable representation for the corresponding bit used in the option set or an empty LocalizedText for a bit that has no specific meaning. The order of the bits of the bit mask maps to a position of the array, i.e. the first bit (least significant bit) maps to the first entry in the array, etc.
The DataType of this VariableType shall be capable of representing a bit mask. It shall be either a numeric DataType representing a signed or unsigned integer, or a ByteString. For example, it can be the BitFieldMaskDataType.
Provides the bit mask in an array of Booleans.
This allows subscribing to individual entries of the bit mask. The order of the bits of the bit mask points to a position of the array, i.e. the first bit points to the first entry in the array, etc.
