[Visual Basic]

Public Property WriteValueAutomatic() As Boolean

  Public Get

  End Get

  Public Set

  End Set

End Property

[C#]

public bool WriteValueAutomatic { public get; public set; }

Remarks

If this property is set true (default case) a value object is written automatically by assigning it to its connected variable object.

Example

For writing values to structure members it is useful to set this property false:

Variable structVar = new Variable(cpuObj,"stVar" );
structVar.Connect();
structVar.WriteValueAutomatic = false;
// Setting member values
structVar.Value["elem_BOOL"] = true;
structVar.Value["elem_SINT"] = 15;
structVar.Value["elem_DINT"] = 345578;
// Writing whole structure
structVar.WriteValue();
structVar.WriteValueAutomatic = true;
