r2114[0...1] Run time counter
Displays run time counter.
It is the total time the inverter has been powered up. When power is switched off, the value is saved, and
then restored on powerup. The run time counter will be calculate as followed:
Multiply the value in r2114[0] by 65536 and then add it to the value in r2114[1]. The resultant answer will
be in seconds. This means that r2114[0] is not days. Total powerup time = 65536 * r2114[0] + r2114[1]
seconds.
Example: If r2114[0] = 1 and r2114[1] = 20864
We get 1 * 65536 + 20864 = 86400 seconds which equals 1 day.

P2115[0...2] Real time clock
Displays real time.
All inverters require an on-board clock function with which fault conditions may be time-stamped and
logged. However, they have no battery backed Real Time Clock (RTC). Inverters may support a software
driven RTC which requires synchronization 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 power-cycle 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.

P2120 Indication counter
Indicates total number of fault / warning events. This parameter is incremented whenever a fault / warning
event occurs.
P2150[0...2] Hysteresis frequency
f_hys [Hz]
Defines hysteresis level applied for comparing frequency and speed to threshold.
