QualityChoiceBitField Property (DAQuality)



OpcLabs.EasyOpcClassic Assembly > OpcLabs.EasyOpc.DataAccess Namespace > DAQuality Class : QualityChoiceBitField Property
Gets the QualityChoice bit field.
Syntax
'Declaration
 
<DefaultValueAttribute(Mono.Cecil.CustomAttributeArgument)>
<XmlIgnoreAttribute()>
Public ReadOnly Property QualityChoiceBitField As DAQualityChoice
'Usage
 
Dim instance As DAQuality
Dim value As DAQualityChoice
 
value = instance.QualityChoiceBitField
[DefaultValue(Mono.Cecil.CustomAttributeArgument)]
[XmlIgnore()]
public DAQualityChoice QualityChoiceBitField {get;}
[DefaultValue(Mono.Cecil.CustomAttributeArgument)]
[XmlIgnore()]
public:
property DAQualityChoice QualityChoiceBitField {
   DAQualityChoice get();
}
Remarks

You cannot set the QualityChoice using a property; use SetQualityAndSubstatus method instead. This approach is needed as the semantics of the Status depends on the QualityChoice, and therefore setting just QualityChoice could lead to inconsistent or undesired contents of the DAQuality.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2012, Windows Server 2016; .NET Core, .NET 5, .NET 6: Linux, macOS, Microsoft Windows
