specified with the initial value given by value
.
C#
public OpcConditionVariableNode(OpcName name, object value)
Parameters
name

C#
public OpcConditionVariableNode(OpcName name, OpcNodeId id)
Parameters
name
OpcName
The OpcName through that the new condition variable node can be accessed.
id
OpcNodeId
The OpcNodeId through that the new condition variable node can be identified and accessed.
Initializes a new instance of the OpcConditionVariableNode class accessible by the name
and id
specified with the initial value given by value
.
C#
public OpcConditionVariableNode(OpcName name, OpcNodeId id, object value)
Parameters
name
OpcName
The OpcName through that the new condition variable node can be accessed.
id
OpcNodeId
The OpcNodeId through that the new condition variable node can be identified and accessed.
value
Object
The initial value of the new condition variable node.
Gets the default identifier which identifies the node that defines the underlying node type from that this OpcInstanceNode has been created.
C#
protected override OpcNodeId DefaultTypeDefinitionId { get; }
Property Value
The OpcNodeId of the type node from that this OpcInstanceNode has been created from. These type node defines the typical structure of an instance node of its type definition. If there exists no specific type definition node a null reference (Nothing in Visual Basic).
Gets or sets a value which indicates the time of the last change of the Value of this condition variable.
C#
public DateTime SourceTimestamp { get; set; }
Property Value
The time of the last change of the Value of this OpcConditionVariableNode.
Remarks
Its value should be the same time that would be returned from the read service inside the OpcValue structure for the condition variable Value attribute.
Gets the OpcPropertyNode´1 of the SourceTimestamp property.
C#
public OpcPropertyNode<DateTime> SourceTimestampNode { get; }
Property Value
An instance of the OpcPropertyNode´1 class.
