If you double-click on a DP slave 611U in the station window, the dialog box:
“DP slave properties” opens.
We recommend activating the equidistant DP cycle for all DP slaves 611U by
activating the equidistant DP cycle within the selected DP slave 611U and finally
adjusting.
During the adjustment, all:

DP slave properties
displayed in the tab: Clock Synchronization
are transferred to all DP slaves of the same type in the configuration, here DP
slave 611U.

Notice
If there are different types of equidistant DP slaves in a S7 project, e.g. different
SIMODRIVE drives, ADI4, etc., the following steps:
1. Synchronize drive to equidistant DP cycle
2. Adjust
must be performed for each type of DP slave first before you can go on to set
the other parameters.
