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.
