WriteNarrowestRealType Property (UAClientSessionParameters)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Engine Namespace > UAClientSessionParameters Class : WriteNarrowestRealType Property
When writing to nodes of OPC UA data type Number and the type is not given explicitly, use the narrowest type available.
Syntax
'Declaration
 
Public Property WriteNarrowestRealType As Boolean
'Usage
 
Dim instance As UAClientSessionParameters
Dim value As Boolean
 
instance.WriteNarrowestRealType = value
 
value = instance.WriteNarrowestRealType
public bool WriteNarrowestRealType {get; set;}
public:
property bool WriteNarrowestRealType {
   bool get();
   void set (    bool value);
}

Property Value

The default value of this property is False.

Remarks

If this property is false and the type is not given explicitly, the client will attempt to write Double when the variable data type is Number.

Note that when this property is true, the written value can lose precision!

In order to obtain or modify this parameter, in the default state (when OpcLabs.EasyOpc.UA.EasyUAClientCore.Isolated equals to false), access UAClientAdaptableParameters.SessionParameters property of static OpcLabs.EasyOpc.UA.EasyUAClientCore.AdaptableParameters. If you have set OpcLabs.EasyOpc.UA.EasyUAClientCore.Isolated to true, you need to access UAClientAdaptableParameters.SessionParameters property of OpcLabs.EasyOpc.UA.EasyUAClientCore.IsolatedParameters.

The getter method of this property is pure, i.e. it does not have observable side effects.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.
