The QueueName parameter with DataType String specifies the queue in the Broker that receives NetworkMessages sent by the Publisher. This could be the name of a queue or topic defined in the Broker.
The ResourceUri property of DataType String allows the transport implementation to look up the configured key from the corresponding KeyCredentialConfigurationType instance defined in OPC 10000-12 to use for authenticating access to the specified queue.
If this String is not null or empty, it overrides the ResourceUri of the PubSubConnection authentication settings.
The parameter AuthenticationProfileUri of DataType String allows the selection of the authentication protocol used by the transport implementation for authenticating access to the specified queue.
If this String is not null or empty, it overrides the AuthenticationProfileUri of the PubSubConnection transport settings defined in 6.4.2.2.2.
The RequestedDeliveryGuarantee parameter with DataType BrokerTransportQualityOfService specifies the delivery guarantees that shall apply to all NetworkMessages published by the WriterGroup unless otherwise specified on the DataSetWriter transport settings. The DataType BrokerTransportQualityOfService is defined in 6.4.2.1.
The value NotSpecified is not allowed on the WriterGroup. If the selected delivery guarantee cannot be applied, the WriterGroup shall set the state to Error.
This Structure DataType is used to represent the broker-specific transport mapping parameters for WriterGroups. It is a subtype of the WriterGroupTransportDataType defined in 6.2.6.7.2.
The BrokerWriterGroupTransportDataType is formally defined in Table 128.
