Cyclical task Time interval
Event task Event number (number of interrupt)

The instructions in section Task Priorities must be observed when
assigning priorities.
Programs must be assigned to tasks before they can be executed.
Assigning a program to a task means that an instance of the program
will be executed when the task is activated. Different instances of a
program can be assigned to different tasks.
Several programs can be assigned to one task. In this case the first
program in the task directory will be executed first. Then the next
program will be executed, and so on.
