Source block specifies -1 sample time

Diagnostic action to take when a source block specifies a sample time of -1

Model Configuration Pane: Diagnostics / Sample Time

Description

The Source block specifies -1 sample time parameter specifies the diagnostic action to take if a source block (such as a Sine Wave block) specifies a sample time of -1.

Settings

warning (default) | none | error

none: Simulink^® software takes no action.
warning: Simulink software displays a warning.
error: Simulink software terminates the simulation and displays an error message.

Tips

The Random Source block does not obey this parameter. If its Sample time parameter is set to -1, the Random Source block inherits its sample time from its output port and never produces warnings or errors.
Some Communications Toolbox™ blocks internally inherit sample times, which can be a useful and valid modeling technique. Set this parameter to none for these types of models.
