Tip!

Note that data inconsistencies may occur if analog input 1 is used several times within the cyclical

task.

• As the process image is updated every 3 ms within the 40 ms of cyclical task processing,

there may be different input values for analog input 1.

Event-controlled task (EVENT)

• If system organization units are used in one event-controlled task only, their process image

will be generated in the event-controlled task.

• If the same system organization units (that are not also used in a time-controlled task) are

used in two event-controlled tasks, their process image will be generated in the cyclical task.

Tip!

For further information about tasks, refer chapter 8.8, “Task configuration”. (^ 8-29)

Interrupt-controlled task

• If system organization units are used in one event-controlled task only, their process image

will be generated in the event-controlled task.

• If the same system organization units (that are not also used in a time-controlled task) are

used in an event-controlled and an interrupt-controlled task, their process image will be

created in the cyclical task.
