Synchronizing the SINAMICS clock
Proceed as follows to convert the SINAMICS clock to UTC format and to synchronize this
with the SIMOTION clock:
1. In the project navigator, call the context menu of the SIMOTION D410.
2. Select the "Properties" entry in the context menu.
3. Select the "Perform time synchronization with SINAMICS drive units" option in the
Note
This setting is automatically activated for new projects from V4.2 and applies for all drive
units connected to the SIMOTION D410. The SINAMICS clock is automatically
synchronized with the SIMOTION clock for all drive units with configured message
frame 39x.
The first time synchronization is performed after the SIMOTION D control unit has reached
the RUN operating state.
To compensate for deviations between the SIMOTION and SINAMICS clocks, the time of
day is automatically resynchronized at regular intervals.
Via the system variable _driveStates.allClocksSynchronized on the device, the user program
can query whether the automatic time synchronization is activated (=YES) or deactivated
(=NO).
Before the first synchronization, alarms and messages are stored with the time stamp valid
in the SINAMICS at this time, all subsequent alarms and messages with the synchronized
time.
The first time synchronization after switching on is entered with the status of the operating
hours counter and the time (UTC time, synchronized with SIMOTION) in the diagnostics
buffer of the drive (e.g. SINAMICS Integrated).
