C#

public OpcAnalogItemNode(OpcName name, T value)


Parameters

name OpcName

The OpcName through that the new analog item node can be accessed.

value T

The initial value of the new analog item node.

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.

C#

public override OpcDataType DataType { get; set; }


Property Value

OpcDataType

One of the members defined by the OpcDataType enumeration.

Value

Gets or sets the value of the analog item node.

C#

public T Value { get; set; }


Property Value

T

A T representing the value of the analog item node. This can be also a null reference (Nothing in Visual Basic).

InitializeDefaults()

Initializes the default values used by the OpcAnalogItemNode´1.

C#

protected override void InitializeDefaults()


Remarks

This method is used to ensure the availability of appropriate node specific default values. For more information like when this method is to be overwritten see InitializeDefaults.
