The endpoint (see "transport_layer.url") is an OPC UA interface and provides several means of use by a client (Browse, Read, Write, Subscribe). The following items allow any connected client to access directly all server data without prior use of browsing, provided that it has knowledge of the PIVOT object it needs and there related types.
