OPC UA Client Driver Statistics Dialog

The Show Stats button will display the following information about an OPC UA Client driver tag.

Note the Endpoints button. This trouble-shooting tools displays the list of OPC UA Server Endpoint information that is retrieved by the driver and held internally.

An OPC UA server may offer multiple endpoints that can be used by clients to connect to it. The endpoints vary in terms of the authentication methods and security levels. The dialog shows what VTScada has received back from the server when it makes its initial (unsecured) connection to retrieve the endpoints. The driver will then choose the most secure endpoint available with the configured authentication method.
