EEPROM log data structure
Note:
22/34
●

●

●
For each tamper entry log, the tamper count: number of tampers in month
D: date and T: time is of 3 bytes.
Total cumulative energy log
Two duplicate entries are stored. One at the start of EEPROM and another at the end
of EEPROM
This is done to make sure that, if EEPROM is corrupted at one point, another entry with
the correct CRC is considered as a valid value
7 bytes (4 bytes: kWh, 2 bytes: impulse count and 1 byte: CRC): total cumulative
energy entry
Cumulative energy until last month
Cumulative energy until last month states energy consumed up to the last calendar
month reset
month
Monthly maximum demand
3 bytes (1 byte: integer value and 2 bytes: impulse count): MD value, 3 bytes (date) 3
bytes (time)
Current monthly cumulative energy
Current monthly cumulative energy states energy consumed in that particular current
month until the last calendar month reset
6 bytes (4 bytes: kWh and 2 bytes: impulse count), current cumulative energy entry
Monthly average PF
PF average value is the sum of PF readings and PF averaging count is the number of
PF readings. 4 bytes (PF average value) 2 bytes (PF averaging value)
Monthly tamper log
For the monthly tamper log, the following four types of tamper data are logged:
–
–
–
–
For each tamper, there are 4 entries per month:
–
–
–
6 bytes (4 bytes: kWh and 2 bytes: impulse count): cumulative energy entry up to last
Earth tamper
Reverse tamper
Neutral missing tamper
Case tamper
1 byte: tamper count
3 bytes: date
3 bytes: time.
