Create a periodic task
A periodic task performs a function or functions at a specific rate.
Important: Be sure that the time period is longer than the sum of the run times of all the programs assigned to the task.
•
If the controller detects that a periodic task trigger occurs for a task that is already operating, a minor
fault occurs (overlap).
•
Priorities and run times of other tasks may also cause an overlap.
