3.4 Configuring PROFINET (only for D410 PN)
Setting the send cycle in HW Config
The PROFINET send cycle always forms the basis for the SIMOTION cycles if the "IRT
communication" real-time class is set and data are being transferred. Set the send cycle in
the "Domain Management" dialog box of HW Config. Open this dialog by selecting the "Edit"
> "PROFINET IO" > "Domain Management ..." command in HW Config.
The set PROFINET send cycle is displayed in SIMOTION SCOUT as "Bus data cycle" in the
"System Clocks - D410..." dialog box. Select the SIMOTION D410 PN in the project tree, and
then select the "Set system clocks" option in the "Target system" > "Expert" menu.
The PROFINET interface supports send cycle times within the range 0.5 ms < send cycle <
4 ms. The maximum configurable resolution is 0.125 ms.
Note
If there are I/O devices with RT class "RT" in a sync domain, only the send cycle clock
settings 0.5 ms; 1 ms; 2 ms and 4 ms are available.
The table below shows which ratios you can set for the system clocks of SIMOTION D410
PN based on the DP cycle of SINAMICS Integrated or on the PROFINET send cycle.

The minimum servo cycle length that can be set is 2 ms.

Rules for SIMOTION D410 PN

Rules for using the PROFINET send cycle
If the PROFINET send cycle is the basis for the cycles, ensure that the DP cycle of the
SINAMICS Integrated and the servo cycle are equal.
The basis for the system clocks is generated internally if the PROFINET interface is not
operated with RT class IRT or if IRT is set and no data are being transferred. This also
applies if the PROFINET interface is operated as synchronization master with RT class IRT
and data are being transferred. The SIMOTION device does not have to synchronize itself
with an external cycle.
The basis for system clocks is derived from the clock signals received at the PROFINET
interface if this interface is operated as synchronization slave with RT class IRT. The
SIMOTION device does not have to synchronize itself with this external clock.
A substitute clock of a duration equivalent to the configured clock is generated internally if
the PROFINET interface has not received a clock signal.
The clock settings are included in the project download to the SIMOTION device and are
adjusted according to specification.
