Aperiodic Trigger
Aperiodic Trigger
Configure aperiodic trigger (interrupt-driven tasks).
For more information, see Tasks and Mapping.
Name
Specify a unique name for the interrupt-driven task configuration.
Settings
Default:
Interrupt
Enter a unique character vector to identify the interrupt-driven task configuration. This value must be a valid MATLAB® variable.
For more information, see Tasks and Mapping.
Color
Specify a color for the interrupt icon.
Settings
Default: Blue
Click the color picker icon to select a color for the interrupt icon.
Tips
The interrupt icon appears on the top left of the Model block. It indicates the task to which the Model block is assigned.
As you add an interrupt, the software automatically assigns a color to the interrupt icon, up to six colors. When the current list of colors is exhausted, the software reassigns previously used colors to the new interrupts, starting with the first color assigned.
If you select a different color for an icon and then use the software to automatically assign colors, the software assigns a preselected color.
For more information, see Tasks and Mapping.
Aperiodic trigger source
Specify the trigger source for the interrupt-driven task.
Settings
Default:

Signal number [2,SIGRTMAX-SIGRTMIN-1]
Enter the POSIX® signal number as the trigger source.
Settings
Default:
2
Minimum:
2
Maximum:
SIGRTMAX-SIGRTMIN-1
Enter the POSIX signal number as the trigger source.
Dependencies
Aperiodic trigger source > Posix signal (Linux/VxWorks 6.x) enables this parameter.

Event name
Enter the name of the event as the trigger source.
Settings
Default:
ERTDefaultEvent
Change
ERTDefaultEvent
to the actual trigger source event.
Dependencies
Aperiodic trigger source > Event (Windows) enables this parameter.
