Unspecified bus object at root Outport block

Diagnostic action to take when root Outport block of referenced model does not specify bus object for bus output

Model Configuration Pane: Diagnostics / Connectivity

Description

The Unspecified bus object at root Outport block configuration parameter determines the diagnostic action to take when generating a simulation target for a referenced model if any root Outport block of the referenced model receives a bus and does not specify a Simulink.Bus object.

Settings

warning (default) | none | error

none

The software takes no action.

warning

The software displays a warning.

error

The software terminates the simulation and displays an error message.

Tips

• This diagnostic applies only when a model is used as a referenced model. Simulating or updating the model on its own does not invoke the diagnostic.

• A root Out Bus Element block does not require a Simulink.Bus object for the corresponding Model block to output a bus.

• When a root Outport block receives a virtual bus and does not specify a Simulink.Bus object, the corresponding Model block output is a vector.
