3.4.4 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 timebase for the system clocks are generated internally if the PROFINET interface is not
operated with RT class IRT with high performance or IRT with high performance is set, but
no data is being transferred. This also applies if the PROFINET interface is operated as
synchronization master with RT class IRT with high performance and data is 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 with high
performance. 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.
