*Date and time of an event are calculated in this way:
Event Date/Time = Timestamp Hi (seconds) + (216) x Timestamp Low (seconds) + (01-Jan-2014 00hh:00min:00sec)
** The daily maximum and minimum data were saved starting from the nearest day, in registers 0x2100 and 0x2101, at the farthest day, in registers
0x215E e0x215F.
