Sinamics Diagnostic Buffer - Siemens SIMOTION D410 Commissioning Manual

Note
The time synchronization must be performed "applicatively" for SIMOTION versions < V4.2.
You can find a sample program in the SIMOTION Utilities & Applications.
If the "applicative time synchronization" is used for SIMOTION versions ≥ V4.2, the time
synchronization must be deactivated via the "Settings on the Device" dialog box.
SIMOTION Utilities & Applications is part of the scope of delivery of SIMOTION SCOUT.
Error correction
If problems occur with time synchronization, this may be due to deactivated symbolic
assignment to incorrect configuration information (Fast IO configuration).
For more information, see Section Message frame configuration (Page 121).
Compensation of runtime deviations
To compensate for deviations between the SIMOTION and SINAMICS clocks, the time of day
is automatically resynchronized at regular intervals.
The following behavior must be taken into consideration when setting the SIMOTION time:
● "Time/date to be set" is after "Time/date on SINAMICS": Time and date are corrected on
● "Time/date to be set" is before "Time/date on SINAMICS": The SINAMICS clock must be
Adopting this procedure ensures that the sequence of SINAMICS diagnostic buffer entries
remains the same, even when the runtime differences are aligned.
The SINAMICS clock operates with a resolution of 1 ms. A synchronization accuracy of 1 ms
can be achieved for all bus cycle clocks that can be divided exactly by 1 ms (e.g. 1 ms, 2 ms,
3 ms, etc.).
Due to system considerations, a slightly lower synchronization accuracy is achieved for all bus
cycle clocks that cannot be divided exactly by 1 ms (e.g. 1.25 ms).
If the drive unit does not have an isochronous connection on SIMOTION, this can result in
runtime differences of milliseconds (depending on the set cycle clock ratios).
