Dim dataVariable As UADataVariable
Dim writeValue As Object
 
UADataVariableExtension.UpdateWriteAttributeData(dataVariable, writeValue)

[Extension()]
public static void UpdateWriteAttributeData( 
   UADataVariable dataVariable,
   object writeValue
)

Parameters

dataVariable

The data variable that will be modified.

The value of this parameter cannot be null (Nothing in Visual Basic).

writeValue

The variable value modified by OPC writes.

The value of this parameter can be null (Nothing in Visual Basic).

You can use this method to set the initial data of a writable data variable.

This method sets the WriteAttributeData property so that it contains the specified writeValue, and the current time as its source timestamp. If WriteLoopback is true (the default), a clone of the new write attribute data is also set to the ReadAttributeData property.

This is an extension method (info: C#, VB.NET). In languages that have support for extensions methods (such as C# and VB.NET), you can use the extension method as if it were a regular method on the object that is its first parameter. In other languages (such as with Python.NET), you will call the extension as a static method, and pass it the object on which it acts as its first parameter.
