Bit 31-28 = Year-high* Bit 27-24 = Month
Bit 23-21 = Year-low* Bit 20-16 = Day
Bit 15 = Summer time flag** Bit 14-13 = Century
Bit 12-8 = Hour
Bit 7 = Error flag
Bit 6 = Reserved for future use***
Bit 5-0 = Minute
*The year is read by combining the year-high
and year- low field. For example, year-high =
0010 and year-low
= 010 => year = 0010010
**0 = standard time, 1= daylight-saving time
***0 = timestamp is valid, 1 = timestamp is not
valid
Energy consumption (Wh, J)
4406xxxxxxxx = MWh, 3 decimals = kWh
440Exxxxxxxx = GJ, 3 decimals
44FB0Dxxxxxxxx = Gcal, 3 decimals
44863Dxxxxxxxx = MMBTU, 3 decimals
Note: Before a midnight reading has been
performed the Function field of the DIF is set
to "value during error state" to indicate that the
value is not valid.
Example:
740600000000 = MWh, 3 decimals = 0 kWh
