The PubSubcomponents have configuration property lists as KeyValuePairarrays. These optional configuration properties extend the configuration parameters defined for the different PubSubcomponents.

The configuration properties are mainly used as protocol or product specific parameters influencing the behaviour of the PubSub application. These properties may contain information that should not be visible outside the configuration tools and PubSub applications. Therefore the properties shall not be included in the PubSubConnectionDataType, WriterGroupDataTypeand DataSetWriterDataTypewhen sent in discovery messages.

The configuration are defined in different sections in the scope where they are used. The properties that can be applied to all PubSub components are defined in Table 4.

The NamespaceIndexof the QualifiedNamein the KeyValuePairfor properties defined in this document shall be 0. The Nameof the QualifiedNameis the property name from Table 4. The DataTypeof the Valuein the KeyValuePairshall be the DataTypedefined in Table 4.

Table 4formally defines the standard PubSubconfiguration.
