Property Value

The default value of this property is False.

In order to obtain or modify this parameter, in the default state (when OpcLabs.EasyOpc.UA.EasyUAClientCore.Isolated equals to false), access UAClientAdaptableParameters.DiscoveryParameters property of static OpcLabs.EasyOpc.UA.EasyUAClientCore.AdaptableParameters. If you have set OpcLabs.EasyOpc.UA.EasyUAClientCore.Isolated to true, you need to access UAClientAdaptableParameters.DiscoveryParameters property of OpcLabs.EasyOpc.UA.EasyUAClientCore.IsolatedParameters.

During server discovery, when enabled, checks each ApplicationDescription returned by the FindServers OPC-UA service. Problems found are logged, and invalid application descriptions are then ignored.

Following aspects of the application description are checked:

• ApplicationUri must not be empty.
• ApplicationUri must be valid.
• Host name or IP address in the ApplicationUri must be valid.
• ProductUri must not be empty.
• ApplicationName should not be empty.
• Locale should be supported.
• DiscoveryUrls must be present.
• DiscoveryUrls should not be empty.

Where "must" is used, the condition must be fulfilled for the application description to be valid. Where "should" is used, the condition is only a recommendation (and a failure is just logged).

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