8.3 Task management
In the programmable variant of the Prepared
Solution the different functionalities are called in different tasks as a function of the processing
priority. The following tasks have already been added:
Task 1 contains the main core of the application. This task must always be processed with the
highest priority, even if the user adds further tasks. It is called at 2ms intervals.
Task 2 calls the machine sequence in which the axis control is applied. In addition calculations
are made and the master frequency evaluated using the normalisation factor.
Task 3 contains the multiplexer and the error management.
TIP!
The user can add further tasks and call custom programs in these additional tasks. Here the
following conditions are to be observed:
• No task is allowed to have a higher priority and a shorter interval time than task 1.
• No user tasks are allowed to have a higher priority and/or a shorter interval time than task
2.
• Further networks can be added to the existing program blocks (e.g. POU MotionControl),
as long as the processing times for the task called do not cause any task overflow.
