4.8.4 Runtime measurement
When the PLC program has started, the controller continuously carries out a runtime measurement.
The current and maximum task runtimes of the single tasks are displayed in the codes C02121/1...2
to C02129/1...2 :

Tip!
On the basis of the runtime measurement, you can detect the amount of the remaining
free calculating time in the different priority levels.
The free calculating times must not simply be added since each extension in a higher-
priority task automatically affects the free calculating time in the lower-priority tasks.
