Output cams / measuring inputs with vector drives
With vector drives, the cycle clock ratios (current controller cycle clock, speed controller
cycle clock, sampling time of the I/Os, etc.) depend on the number of vector drives, or with
chassis units also on the device type used.
Note the information in Section Current controller cycle clocks <> 125 µs / use of output
cam
s and measuring inputs (Page 224).

Additional information on quantity structures and cycle clock settings can be found in the
SINAMICS S120
Function Manual.
6.5.3 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.
To set the clock from SIMOTION SCOUT, select the D4x5-2 in the project tree and then
select "Target system" > "Set time" in the menu.
Alternatively, the clock can be set using the "rtc" system function block.
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 diagnostics buffer for entries.
If faults and warnings 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.
