10.2 Detecting the task utilisation of the application (T
Task utilisation
)
The time T
Task utilisation
cannot be calculated. It is determined in the running system. For
this the system is commissioned on the basis of cycle times that are sufficiently long, and
afterwards it is optimised.
In order to detect the task utilisation, use the task editor in the »PLC Designer«.
10.2.1 Display of the system utilisation in the »PLC Designer« with the task editor
The task editor contains a dialog window consisting of two parts.
 The left part represents the tasks in a configuration tree.
 If the Task configuration entry is highlighted, the utilisation for all tasks is shown in bar
diagrams in the right dialog window.

How to display the system utilisation:
1. Select the Resources tab:
2. Open the task configuration in the online mode of the »PLC Designer«.

Note!
In order to be able to display the utilisation for all tasks, the IEC61131
SysTaskInfo library has to be included in the project.
