Calling ProcessConnectionConfigurationSets with Action set to ActionEstablishConnectionsEnabled, ActionEstablishConnectionsDisabled, or ActionEstablishConnections shall establish the Connections contained in the ConnectionConfigurationSets and their related communication model.

Establishing connections shall follow the behaviour specified in 6.7.3.2.

The ConnectionManager shall ensure the expected result of the requested Action as follows:

• Calling ProcessConnectionConfigurationSets with Action set to ActionEstablishConnectionsEnabled shall establish all Connections contained in the ConnectionConfigurationSets with a disabled communication model and include EnableCommunicationCmd in the command sequence. A disabled communication model has Enabled flags set to FALSE for all DataSetReader and DataSetWriter configuration elements and to TRUE for all other elements (WriterGroup, ReaderGroup, PubSubConnection, and PublishSubscribe).

A disabled ClientServer communication model may be defined in a future version of this document.

• Calling ProcessConnectionConfigurationSets with Action set to ActionEstablishConnectionsDisabled shall establish all Connections contained in the ConnectionConfigurationSets with a disabled communication model and omit EnableCommunicationCmd from the command sequence. A disabled communication model has Enabled flags set to FALSE for all DataSetReader and DataSetWriter configuration elements and to TRUE for all other elements (WriterGroup, ReaderGroup, PubSubConnection, and PublishSubscribe).

Calling ProcessConnectionConfigurationSets with Action set to ActionEstablishConnections shall establish all Connections contained in the ConnectionConfigurationSets with the communication model as configured by the engineering tool generating the communication model. The ConnectionManager shall apply the communication model as is using the SetCommunicationConfigurationCmd and omit EnableCommunicationCmd from the command sequence. Depending on the state of the configuration elements (e.g., the value of the Enabled flag for PubSub configuration elements), parts of the communication model may be enabled and others disabled. This allows, for example, to have a subset of the Connections enabled and the rest disabled. It is the responsibility of the engineering tool to configure the state of the configuration elements properly and consistently.
