ControlGroups can be used with Connections.
Assume that the EngineeringUnit of Temperature (see Figure D.28) should not change during the lifetime of a Connection. A connection configuration to achieve this behaviour would establish the control of MonitorControl using the EstablishControlCmd, set the EngineeringUnit with the desired unit (e.g., °F) using the SetConfigurationDataCmd, and reassign control to the ConnectionEndpoint using ReassignControlCmd.
