Defining the minimum cycle time of the PLC project

Optimising the system

12.4 Optimising the system

 How to optimise the system:

1. Log in and load project.

2. Check the task processing times.

3. Optimising cycle times:

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

priorities can be decreased.

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

corresponding cycle time in its task utilisation.
