How to access OPC.NET 3.0 (formerly known as OPC Xi)

I want to communicate with KepServerEx using the OPC.NET WCF service.

I have configured the server as described at http://ift.tt/1MKE8BE, with all bindings enabled. Everything seems OK : the service is running, no errors are displayed in the event log, the configured ports are open (tested with telnet, netstat).

The problem is that I don’t know how to reference the service. The configuration window displays the following information:

• Name: KEPServerEXV5_OPCNET

• URL: http://machine_name:64412/OPCServices/serverDiscovery

• Status: Running

I have tried different URI combinations to no avail. I have located the configuration file (xi_server_runtime.exe.config) , but it contains no serviceModel tag, hence no base address or endpoint information. I tried to configure a MEX endpoint as follows:

   <system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior name="OPCNET">
                    <serviceMetadata httpGetEnabled="true"/>
                </behavior>
            </serviceBehaviors>
        </behaviors>

        <services>
            <service behaviorConfiguration="OPCNET" name="KEPServerEXV5_OPCNET">
                <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
            </service>
        </services>
    </system.serviceModel>

but nothing has changed.
