EnableStatusSubscription Property (_UASmartSessionParameters)

Determines whether the server status monitoring subscription will be enabled.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Property EnableStatusSubscription As Boolean

'Usage
 
Dim instance As _UASmartSessionParameters
Dim value As Boolean
 
instance.EnableStatusSubscription = value
 
value = instance.EnableStatusSubscription

bool EnableStatusSubscription {get; set;}

property bool EnableStatusSubscription {
   bool get();
   void set (    bool value);
}

Remarks

Set this parameter to false to disable the server status monitoring subscription. Note that the monitoring is, however, required for full OPC UA compliance. Without the status monitoring subscription, for example, the client will not be able to recognize the server is about to shut down, and will only learn it after the connection breaks, without having chance to distinguish this case from unexpected connection-related errors.

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.

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