WriteNarrowestRealType Property (_UAEnhancedClientSessionParameters)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Engine.ComTypes Namespace > _UAEnhancedClientSessionParameters Interface : 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
 
Property WriteNarrowestRealType As Boolean
'Usage
 
Dim instance As _UAEnhancedClientSessionParameters
Dim value As Boolean
 
instance.WriteNarrowestRealType = value
 
value = instance.WriteNarrowestRealType
bool WriteNarrowestRealType {get; set;}
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 OpcLabs.EasyOpc.UA.Engine.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 OpcLabs.EasyOpc.UA.Engine.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 member or type is for use from COM. It is not meant to be used from .NET or Python. Refer to the corresponding .NET member or type instead, if you are developing in .NET or Python.

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

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
