Description

This command activates the connection to the Cascade DataHub, if available. When the datahub mode is active, the input points are automatically published to the datahub when they change, and output points with the exception-flag set will be automatically updated when the corresponding values in the datahub change. The command must be preceded by the attachNS command.

This command can be used in the configuration file, or modified as required via the command interface.
