Gets or sets a value which indicates in which ways the Value attribute of the variable node can be accessed (read/write) and if it provides current and/or historic data.
public OpcAccessLevel? AccessLevel { get; set; }Public Property AccessLevel As OpcAccessLevel?Property value
One of the members defined by the OpcAccessLevel enumeration if specified; otherwise a null reference (Nothing in Visual Basic). In case of a null reference (Nothing in Visual Basic) the server defined default value of the attribute is used.
ArrayDimensions
Gets the number/lengths of dimensions for an array Value with one or more fixed dimensions.
public OpcArrayDimensions ArrayDimensions { get; set; }Public Property ArrayDimensions As OpcArrayDimensionsProperty value
An instance of the OpcArrayDimensions class which offers the number/lengths of dimensions for an array Value.
Remarks
If the ValueRank does not identify an array of a specific dimension (i.e. ValueRank <= 0) ArrayDimensions can be a null reference (Nothing in Visual Basic). In case of a null reference (Nothing in Visual Basic) the server defined default value of the attribute is used.
DataType
Gets or sets a value which defines a pre-defined used DataTypeId as one of the members defined by the OpcDataType enumeration to simplify querying standard data types. A null reference (Nothing in Visual Basic) indicates that the attribute is undefined and its default value is used.
public virtual OpcDataType? DataType { get; set; }Public Overridable Property DataType As OpcDataType?Property value
One of the members defined by the OpcDataType enumeration.
DataTypeId
Gets or stets the identifier which identifies the node that defines the type of data represented by the variable node. A null reference (Nothing in Visual Basic) indicates that the attribute is undefined and its default value is used.
public OpcNodeId DataTypeId { get; set; }Public Property DataTypeId As OpcNodeIdProperty value
The OpcNodeId of the data type node which defines the type of data represented by the variable node. These data type node defines either a simple or a complex type of data accessible by the Value property.
IsHistorizing
Gets or sets a value indicating whether the server is actively collecting data for the history of the variable.
public bool? IsHistorizing { get; set; }Public Property IsHistorizing As Boolean?Property value
The value true if the server is actively collecting data; otherwise the value false (the default value) or a null reference (Nothing in Visual Basic). In case of a null reference (Nothing in Visual Basic) the server defined default value of the attribute is used.
Type
Gets value indicating the predefined underlying type definition the new node will represent an instance of.
public OpcVariableType Type { get; }Public ReadOnly Property Type As OpcVariableTypeProperty value
One of the members defined by the OpcVariableType enumeration or -1 in case of a custom type definition is used (see TypeDefinitionId).
UserAccessLevel
Gets or sets a value which indicates in which ways the Value attribute of the variable node can be accessed (read/write) and if it provides current and/or historic data taking user access rights into account.
public OpcAccessLevel? UserAccessLevel { get; set; }Public Property UserAccessLevel As OpcAccessLevel?Property value
One of the members defined by the OpcAccessLevel enumeration if specified; otherwise a null reference (Nothing in Visual Basic). In case of a null reference (Nothing in Visual Basic) the server defined default value of the attribute is used.
Value
Gets or sets the value of the variable node which may be simple or complex. A null reference (Nothing in Visual Basic) indicates that the attribute is undefined and its default value is used.
public object Value { get; set; }Public Property Value As ObjectProperty value
A object representing the value of the variable node.
ValueRank
Gets or sets a value which indicates whether the value attribute of the variable is an array and how many dimensions the array has.
public int? ValueRank { get; set; }Public Property ValueRank As Integer?Property value
One of the values defined by the ValueRanks class or a null reference (Nothing in Visual Basic). In case of a null reference (Nothing in Visual Basic) the server defined default value of the attribute is used.
Methods
OfType
Retrieves an instance which represents the definition of a variable type that can be used to define OpcAddVariableNode command instances using the type of variable node represented by the OpcAddVariableNode.TypeDefinition instance provided.
public static OpcAddVariableNode.TypeDefinition OfType(
OpcNodeId typeDefinitionId)Public Shared Function OfType(
typeDefinitionId As OpcNodeId) As OpcAddVariableNode.TypeDefinitionParameters
| Name | Type | Description |
|---|---|---|
typeDefinitionId | OpcNodeId | The OpcNodeId of the type definition to provide. |
Returns
OpcAddVariableNode.TypeDefinition
A new instance of the OpcAddVariableNode.TypeDefinition class which can be used to define typed OpcAddVariableNode command instances.
