The SubscriberConfigurationType is formally defined in Table 95. It describes the Subscriber specific information for the Subscriber of an information flow. The configuration of the Subscriber requires additional information from the parent object, which applies to all Subscribers.

The optional Address specifies the network address to be used for the reception of NetworkMessages at the Subscriber of the information flow. This is an abstract type, and a concrete subtype shall be used. For the usage of Address, see OPC 10000-14 Clause “PubSub mappings”, Subclause “Transport protocol mappings”. If Address is omitted and the parent Object contains a multicast network address, the Address of the parent Object shall be used for the Subscriber. If Address is omitted and the parent Object contains a unicast network address, the default reception address with the default port shall be used (e.g., “opc.udp://localhost”; for details, see OPC 10000-14). The configuration is invalid if Address is omitted here and in the parent Object.
The MessageReceiveTimeout specifies the maximum acceptable time between DataSetMessages. Received by the Subscriber. For the definition of MessageReceiveTimeout, see OPC 10000-14.
The optional ReceiveQos specifies the Quality of Service to be used for the Subscriber of the information flow. It shall only be present if Qos is present in the parent Object. If present, ReceiveQos will override Qos ReceiveQos of the parent Object. For the definition of ReceiveQos, see OPC 10000-14.
