4.
Click "New" to open the "Properties - New PROFIBUS Subnet" dialog box.
5.
Name the new subnet, and then enter its properties in the "Network settings" tab, for
example, the transmission rate.
6.
Click "OK" to accept the settings.
The new subnet is now displayed in the "Properties - PROFIBUS interface DP/MPI"
dialog box and is ready for being interconnected with the PROFIBUS DP interface.
7.
Save and compile the changes.
The PROFIBUS subnet you created is displayed as a graphic object in HW Config.
3.3.5
Setting the DP cycle and system cycle clocks
All system clocks for SIMOTION D410 DP are based on the DP cycle of SINAMICS
Integrated, which must be set in HW Config.
In HW Config, double-click the SINAMICS drive at the integrated PROFIBUS. The "DP Slave
Properties" dialog box opens. You can synchronize the DP cycle of SINAMICS Integrated in
the "Isochronous mode" tab.

Range of values for SIMOTION D410 DP
DP cycle
≥ 2 ms
Grid
0.125 ms
The PROFIBUS DP interface of the SIMOTION D410 DP supports operation at a DP cycle
time ≥ 2 ms, at an interval of 0.125 ms. SINAMICS Integrated always runs in isochronous
mode. The cyclic tasks of SIMOTION are therefore always in synchronism with
SINAMICS Integrated.
The set DP cycle of SINAMICS Integrated is displayed as "Bus data cycle" in the "System
Clocks - D410..." dialog box in SIMOTION SCOUT. Select the SIMOTION D410 DP in the
project tree, and then select the "Set system clocks" option in the "Target system" > "Expert"
menu.
The table below shows the ratios you can set for the system clocks of SIMOTION D410 DP
based on the DP cycle.

The minimum servo cycle length that can be set is 2 ms.
If you programmed the PROFIBUS DP interface for operation in isochronous master mode,
you must synchronize its DP cycle with the DP cycle of SINAMICS Integrated in HW Config.
The timebase for the system clocks is generated internally if the DP interface is operated in
isochronous or non-isochronous master mode. SIMOTION D410 does not have to
synchronize itself with an external cycle.
