EffectiveSecurityMode Property (_UADataSetSubscriptionDescriptor)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.PubSub.ComTypes Namespace > _UADataSetSubscriptionDescriptor Interface : EffectiveSecurityMode Property
The effective security mode being used by this descriptor.
Syntax
'Declaration
 
ReadOnly Property EffectiveSecurityMode As UAMessageSecurityModes
'Usage
 
Dim instance As _UADataSetSubscriptionDescriptor
Dim value As UAMessageSecurityModes
 
value = instance.EffectiveSecurityMode
UAMessageSecurityModes EffectiveSecurityMode {get;}
property UAMessageSecurityModes EffectiveSecurityMode {
   UAMessageSecurityModes get();
}

Property Value

The default value of this property is SecurityNone (UAMessageSecurityModes.SecurityNone).

Because there is an implicit conversion from OpcLabs.EasyOpc.UA.Engine.UAMessageSecurityModes to OpcLabs.EasyOpc.UA.Engine.UAEndpointSelectionPolicy, you can simply use the returned OpcLabs.EasyOpc.UA.Engine.UAMessageSecurityModes in any place where OpcLabs.EasyOpc.UA.Engine.UAEndpointSelectionPolicy is expected as input, and the corresponding endpoint selection policy will be constructed automatically from the message security modes. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.Engine.UAEndpointSelectionPolicy.FromUAMessageSecurityModes static method instead.

Remarks

If a security mode is specified in the CommunicationParameters (i.e. it does not equal to OpcLabs.EasyOpc.UA.Engine.UAMessageSecurityModes.None), it becomes the effective security mode. Otherwise, the InferredSecurityMode is used.

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.

Requirements

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