OpcAggregateConfigurationNode Members

Initializes a new instance of the OpcAggregateConfigurationNode class.

C#

public OpcAggregateConfigurationNode()

Initializes a new instance of the OpcAggregateConfigurationNode class as a child node of the parent node given.

C#

public OpcAggregateConfigurationNode(IOpcNode parent)

Parameters

parent IOpcNode

The IOpcNode used as the parent node or a null reference (Nothing in Visual Basic) in the case there is no parent node available.

Initializes a new instance of the OpcAggregateConfigurationNode class accessible by the name specified as a child node of the parent node given.

C#

public OpcAggregateConfigurationNode(IOpcNode parent, OpcName name)

Parameters

parent IOpcNode

The IOpcNode used as the parent node or a null reference (Nothing in Visual Basic) in the case there is no parent node available.

name OpcName

The OpcName through that the new aggregate configurtion node can be accessed.

Initializes a new instance of the OpcAggregateConfigurationNode class accessible by the name and id specified as a child node of the parent node given.

C#

public OpcAggregateConfigurationNode(IOpcNode parent, OpcName name, OpcNodeId id)

Parameters

parent IOpcNode

The IOpcNode used as the parent node or a null reference (Nothing in Visual Basic) in the case there is no parent node available.

name OpcName

The OpcName through that the new aggregate configurtion node can be accessed.

id OpcNodeId

The OpcNodeId through that the new aggregate configurtion node can be identified and accessed.

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

C#

public OpcAggregateConfigurationNode(OpcName name)

Parameters

name OpcName

The OpcName through that the new aggregate configurtion node can be accessed.

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

C#

public OpcAggregateConfigurationNode(OpcName name, OpcNodeId id)

Parameters

name OpcName

The OpcName through that the new aggregate configurtion node can be accessed.

id OpcNodeId

The OpcNodeId through that the new aggregate configurtion node can be identified and accessed.

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).

Gets or sets a value which indicates the minimum percentage of bad data in a given interval required for the status code for the given interval for the processed data requests to be set to bad.

C#

public byte PercentDataBad { get; set; }

Property Value

Byte

A value indicating the percentage of bad data for the processed data requests set to bad. The default value is 100.

Remarks

The PercentDataGood and PercentDataBad must follow the following relationship PercentDataGood >= (100 – PercentDataBad). If they are equal the result of the PercentDataGood calculation is used.

Gets the OpcPropertyNode´1 of the PercentDataBad property.

C#

public OpcPropertyNode<byte> PercentDataBadNode { get; }

Property Value

OpcPropertyNode<Byte>

An instance of the OpcPropertyNode´1 class.

Gets or sets a value which indicates the minimum percentage of good data in a given interval required for the status code for the given interval for the processed data requests to be set to good.

C#

public byte PercentDataGood { get; set; }

Property Value

Byte

A value indicating the percentage of bad data for the processed data requests set to bad. The default value is 100.

Remarks

The PercentDataGood and PercentDataBad must follow the following relationship PercentDataGood >= (100 – PercentDataBad). If they are equal the result of the PercentDataGood calculation is used.

Gets the OpcPropertyNode´1 of the PercentDataGood property.

C#

public OpcPropertyNode<byte> PercentDataGoodNode { get; }

Property Value

OpcPropertyNode<Byte>

An instance of the OpcPropertyNode´1 class.

Gets or sets a value indicating whether the server treats data returned with a status code severity uncertain with respect to aggregate calculations.

C#

public bool TreatUncertainAsBad { get; set; }

Property Value

Boolean

The value true indicates the server considers the severity equivalent to bad, a value equals false indicates the server considers the severity equivalent to good, unless the aggregate definition says otherwise. The default value is true. Note that the value is still treated as uncertain when the status code for the result is calculated.

Gets the OpcPropertyNode´1 of the TreatUncertainAsBad property.

C#

public OpcPropertyNode<bool> TreatUncertainAsBadNode { get; }

Property Value

OpcPropertyNode<Boolean>

An instance of the OpcPropertyNode´1 class.

Gets or sets a value indicating whether the server interpolates data when no boundary value exists (i.e. extrapolating into the future from the last known value).

C#

public bool UseSlopedExtrapolation { get; set; }

Property Value

Boolean

The value false indicates that the server will use a stepped extrapolation format, and hold the last known value constant. A value of true indicates the server will project the value using UseSlopedExtrapolation mode. The default value is false.

Gets the OpcPropertyNode´1 of the UseSlopedExtrapolation property.

C#

public OpcPropertyNode<bool> UseSlopedExtrapolationNode { get; }

Property Value

OpcPropertyNode<Boolean>

An instance of the OpcPropertyNode´1 class.

Applies the configuration specified to the aggregation setup of this OpcAggregateConfigurationNode.

C#

public void ApplyConfiguration(OpcAggregateConfiguration configuration)

Parameters

configuration OpcAggregateConfiguration

The OpcAggregateConfiguration to apply.

Exceptions

ArgumentNullException

The configuration is a null reference (Nothing in Visual Basic).
