Setting the time of day
Time on SIMOTION (real-time clock)
SIMOTION D4x5‑2 has an integrated real-time clock. All events on a module (alarms,
messages, etc.) are "time-stamped" based on the time shown by this real-time clock.
Various options are available to set the clock of the SIMOTION D4x5-2:
● Setting the clock via the engineering system
– SIMOTION SCOUT: Select the SIMOTION D4x5-2 in the project tree and then "Target
system" > "Set time" in the menu.
– SIMOTION SCOUT TIA: Call the "Set time" function at "Online & diagnostics" in the TIA
Portal in the project tree.
● Setting the clock using the "rtc" system function block
● Synchronization of the local time with an NTP time server (as of V4.5)
The status of the NTP time synchronization can be determined with the
_getStateOfNTPClockSynchronisation system function.
For further information on the NTP process, see the
SIMOTION Communication System
Manual and the
SIMOTION SCOUT TIA Configuration Manual.
SINAMICS system runtime (operating hours counter)
Faults and alarms are "time-stamped" based on the system runtime on SINAMICS Integrated
of a SIMOTION D, Controller Extensions and SINAMICS S120 Control Units. This means that
events are recorded by default on the basis of operating hours rather than a particular time of
day or date.
System runtime
The entire system runtime is displayed in CU parameter p2114.
● p2114[0] indicates the system runtime in milliseconds. After reaching 86,400,000 ms (24
hours), the value is reset.
● p2114[1] indicates the system runtime in days.
The counter value is saved when the power is switched off. After the drive unit has been
switched on, the counter continues to run with the value stored when the power was last
switched off.
As a result, the drive displays the system runtime from 00:00:00 on 01/01/1992 in both the
alarm window in SIMOTION SCOUT and the diagnostic buffer for entries.
If faults and alarms need to be "time-stamped" based on a time of day, "Time stamp operating
hours" needs to be changed to "Time stamp UTC format" as described below.
Requirements
A telegram 39x is required for the time synchronization. If the automatic PROFIdrive telegram
setting is selected for the Control Unit, this telegram is used automatically (see Section Calling
the drive wizard (Page 176), Standard/Automatic setting).
