5.4.3 Set time of day
Time on SIMOTION (real-time clock)
SIMOTION D410 features 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.
To set the clock from SIMOTION SCOUT, select the SIMOTION D410 in the project tree,
followed by "Target System" > "Set Time".
Alternatively, the clock can be set using the "rtc" system function block.
SINAMICS system runtime (operating hours counter)
For
SINAMICS S120 Control Units and the SINAMICS Integrated on a SIMOTION D410, faults
and alarms are "time-stamped" on the basis of the system runtime. By default, events are
recorded in terms of operating hours rather than in terms of 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" on the basis of 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
Accessing the drive wizard (Page 82), Standard/Automatic setting).
If the telegrams are specified manually, telegram 39x must be set up. See Section Message
frame configuration (Page 121).
So that drive units can be synchronized with the SIMOTION time, they must support telegram
39x and the UTC (coordinated universal time) time format.
For precise time synchronization, the drive unit must also be operated via an isochronous bus
on SIMOTION. The SINAMICS Integrated with SIMOTION D is always connected
isochronously.
The following Control Units support time synchronization:
