With the log-in, the I/O device configuration is loaded into the controller.

2. Check the task processing times.

3. Optimising the cycle times:

• If technologically required, the cycle times of the remaining tasks with lower priorities

can be decreased.

• Condition: No task with a low priority must assign more than 60 percent of the

corresponding cycle time in its task utilisation.
