5.4.1.5.12 Assignment of the task class
Name:
Cycle time
By assigning the cycle time to a task class, the data exchange between the CPU and module can be prioritized
and adapted to the requirements of the application. Faster task classes result in increased data throughput, but
this increases the system load.
Information:
Using a task class that is too slow can result in new data from the module not being available within a
measurement cycle. The task class must be less than or equal to the maximum cycle time.
Information:
This configuration involves a driver setting that cannot be changed during runtime!

Task class used
5.4.1.5.13 Maximum cycle time
The maximum cycle time defines how far the cycle time of the X2X Link can be increased without causing a
communication error or impaired functionality. The maximum cycle time here is 10 ms.
5.4.1.5.14 Minimum cycle time
The minimum cycle time defines how far the bus cycle can be reduced without communication errors occurring.
Note that very fast cycles decrease the idle time available for handling monitoring, diagnostics and acyclic com-
mands. The minimum cycle time here is 400 ms.
