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.

OpcConditionVariableNode(OpcName)

Initializes a new instance of the OpcConditionVariableNode class accessible by the name specified.

C#

public OpcConditionVariableNode(OpcName name)


Parameters

name OpcName

The OpcName through that the new condition variable node can be accessed.

OpcConditionVariableNode(OpcName, Object)

Initializes a new instance of the OpcConditionVariableNode class accessible by the name specified with the initial value given by value.

C#

public OpcConditionVariableNode(OpcName name, object value)


Parameters

name OpcName

The OpcName through that the new condition variable node can be accessed.

value Object

The initial value of the new condition variable node.

OpcConditionVariableNode(OpcName, OpcNodeId)

Initializes a new instance of the OpcConditionVariableNode class accessible by the name and id specified.

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.

OpcConditionVariableNode(OpcName, OpcNodeId, Object)

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.

DefaultTypeDefinitionId

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

OpcNodeId

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).

SourceTimestamp

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

DateTime

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.

SourceTimestampNode

Gets the OpcPropertyNode┬┤1 of the SourceTimestamp property.

C#

public OpcPropertyNode<DateTime> SourceTimestampNode { get; }


Property Value

OpcPropertyNode<DateTime>

An instance of the OpcPropertyNode┬┤1 class.
