Siemens SIMOTION D4x5-2 Commissioning And Hardware Installation Manual page 231

If the telegrams are specified manually, telegram 39x must be set up (see Section Telegram
configuration (Page 271)).
So that drive units can be synchronized with the SIMOTION time, they must support telegram
39x and the UTC time format.
For precise time synchronization, the drive unit must also be operated via an isochronous bus
on SIMOTION. The SINAMICS Integrated for SIMOTION D and the CX32/CX32‑2 Controller
Extension always have an isochronous connection.
The following Control Units support time synchronization:
● SINAMICS Integrated of the SIMOTION D
● CX32/CX32‑2 Controller Extensions
● SINAMICS S120 CU310, CU310‑2, CU320, CU320‑2 Control Units connected via
PROFIBUS or PROFINET
● SINAMICS S110 Control Units CU305, connected via PROFIBUS or PROFINET
(precondition: as of SCOUT V4.4)
Synchronizing the SINAMICS clock
Proceed as follows to convert the SINAMICS clock to UTC format and to synchronize this with
the SIMOTION clock:
1. Call the D4x5‑2 context menu in the project navigator.
2. Select the "Properties..." entry in the context menu.
3. Select the "Perform time synchronization with SINAMICS drive units" option in the
"Settings" tab of the "Properties - D4x5‑2" dialog box.
Note
This setting is automatically activated for new projects as of V4.2 and applies for all drive units
connected to the D4x5‑2. The SINAMICS clock is automatically synchronized with the
SIMOTION clock for all drive units with configured telegram 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 D4x5‑2 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 diagnostic buffer
of the drive (e.g. SINAMICS Integrated).
