3. In
the "IO devices" table, define the synchronization roles and RT classes of all devices of
the sync domain:
– Define the role of the PLC by opening the dropdown list in the "Synchronization role"
column and selecting "Sync master".
Figure 5-9 Selecting the sync master
– Check whether the synchronization role is set to "Sync slave" for all desired devices.

4. In the "Sync-Domain_1" section, enter a value in the "send clock" dropdown list appropriate
for the "Equidistant DP cycle" setting.
Note
The
send clock of the sync domain and the DP cycle for SINAMICS Integrated must match!
If you have not set the same values for these settings, an error message will be issued when
the configuration is compiled. In this case, match the values and compile the project again.
The "Equidistance DP cycle" setting is contained under "Equidistance" in the properties of
the PROFIBUS Integrated subsystem. (default setting: 2 ms; minimum value: Version-
dependent)
5.5.11 Match values between PROFINET IO and PROFIBUS Integrated
In
case you have used different values, an error message will be issued in the "Info > Compile"
inspector window during the compilation.
The following values must agree:
Isochronous mode values:
● "PLC > Alarms > Isochronous alarms > NCK > Application cycle"
● "PROFINET IO system > Domain management > Sync domains > Sync-Domain_1 > Send
clock"
● "PROFIBUS Integrated_1 > Equidistance > DP cycle > Equidistant DP cycle"
