Public Property CloseTimeout As Integer
'Usage
 
Dim instance As UAClientSessionParameters
Dim value As Integer
 
instance.CloseTimeout = value
 
value = instance.CloseTimeout
[DefaultValue(10000)]
[Unit("ms")]
public int CloseTimeout {get; set;}
[DefaultValue(10000)]
[Unit("ms")]
public:
property int CloseTimeout {
   int get();
   void set (    int value);
}
Remarks

This parameter is not interpreted by the component; it is simply passed down to the OPC UA Stack for processing.

If the session cannot be closed in a timely manner, it is consider closed anyway, and the component will not use the same session again. The timeout prevents the component from waiting too long or indefinitely for the confirmation. This means that any new requests to the same endpoint will open a new session, as with the properly closed sessions.

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.
