3.4.3 Setting the send cycles and system clocks
Prerequisite
The SIMOTION system clocks (servo/IPO/IPO2) are based on the SINAMICS Integrated DP
cycle or the PROFINET send cycle, depending on the PROFINET real-time class and the
type of data transfer. The cycle clock source can be generated "internally" by the
SIMOTION D410; otherwise, it is obtained "externally" from the clock signals received at the
PROFINET interface.

If the PROFINET send cycle forms the basis for the SIMOTION system clocks, the SINAMICS Integrated DP cycle and
the servo cycle are equal.

Synchronized data traffic, e.g. by means of:
- Controller-controller slave-to-slave communication
- I/O device in separate I/O system
Setting the DP cycle in HW Config
Set the DP cycle of SINAMICS Integrated 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.

Grid 0.125 ms
SINAMICS Integrated always operates in isochronous mode. The cyclic tasks of SIMOTION
are therefore always in synchronism with SINAMICS Integrated.
