2-2-4 Examples of Tasks
An overall control task that is set to go to READY status at the start of opera-
tion is generally used to control READY/Standby status for all other cyclic
tasks (including extra cyclic tasks). Of course, any cyclic task can control the
READY/Standby status of any other cyclic task as required by the application.
Combinations of the above classifications are also possible, e.g., classifica-
tion by function and process.
