SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Displays real time.
All inverters require an on-board clock function with which fault conditions may be timestamped and logged.
However, they have no battery backed Real Time Clock (RTC). Inverters may support a software driven RTC which
requires synchronisation with the RTC supplied via a serial interface.
The time is stored in a word array parameter P2115. The time will be set by USS Protocol standard "word array
parameter write" telegrams. Once the last word is received in index 2, the software will start running the timer itself
using internal running 1 millisecond tic. Hence becoming like RTC.
If powercycle takes place, then the real time must be sent again to the inverter.
Time is maintained in a word array parameter and encoded as follows - the same format will be used in fault report
logs.
The values are in binary form.
Index: [0] = Real Time, Seconds+Minutes
[1] = Real Time, Hours+Days
[2] = Real Time, Month+Year
Note: See r0948 (fault time).
Description: Indicates total number of alarm events.
This parameter is incremented whenever an alarm event occurs. It also gets incremented when a warning is
cleared or faults are cleared.
This parameter is used by the PC tools.
