9.3.3
Default task
The default task runs as a background task with the lowest possible user
priority and is not time-monitored. It is activated when all higher-priority user
tasks have been processed. The default task is configured so that it only
uses some of the available residual time. Only one default task is permitted
in each resource. It is recommended only to use cyclical tasks.
Note
All drivers in the I/O configuration that are not explicitly assigned to a
user task automatically activate the default task and are executed in
the context of the default task.
9.3.4
Operating system tasks
Tasks running at the priority level of the operating system include tasks for
communication, debugging, memory management and system control,
unaffected by the user.
