SINAMICS system runtime (operating hours counter)
For SINAMICS S120 control units and the SINAMICS Integrated on a SIMOTION D410,
faults and warnings 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 warnings 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.
Prerequisites
A message frame 39x is required for the time synchronization. If the automatic PROFIdrive
message frame setting is selected for the control unit, this message frame is used
automatically (see Section Accessing the drive wizard (Page 74), Standard/Automatic
s
etting).
If the message frames are specified manually, message frame 39x must be set up. See
section Message frame configuration (Page 115)
So that drive
units can be synchronized with the SIMOTION time, they must support
message frame 39x and the UTC (coordinated universal time) time format.
The following Control Units support time synchronization:
● SINAMICS Integrated of the SIMOTION D410
● SINAMICS S120 CU310, CU310-2, CU320, CU320-2 control units connected via
PROFIBUS or PROFINET
