Constant bus cycle time

Constant bus cycle time
The DP master addresses its assigned DP slaves cyclically. S7 communication may cause
the intervals to vary. You can enable a "bus cycle with constant bus cycle time" to achieve
identical intervals. This ensures data transmission at the same (constant bus cycle time)
intervals.
