Q
Record Format: A Record contains as many bytes as specified by the Historical Log 1 Record Size
Field in the Programmable Settings Block (45463). The first eight bytes in each record is the Time
Stamp. The format of the Time Stamp is:
Byte Format Range Description
0 binary 0 – 99 century
1 binary 0 – 99 year
2 binary 1 – 12 month
3 binary 1 – 31 day
4 binary 0 – 23 hour
5 binary 0 – 59 minute
6 binary 0 – 59 second
7 binary 0 – 100 centisecond
If this historical record was recorded while the meter was in test mode, then only energy readings
will be recorded. All other values requested will be stored with the byte values of 0x055. The most
significant bit of the centisecond byte indicates whether this record was recorded while the meter
was in test mode.
If the historical record was recorded after powering up or the log was reset, the record does not con-
tain information covering a full interval and the most significant bit of the second’s byte will be set.
If the historical record was recorded after time was adjusted, the record might contain more or less
than a full interval’s worth of data. If time is advanced within the current interval, or advanced or
rolled back to outside the current interval, the record contains leass than a full interval’s worth of
data and the most significant bit of the minute byte will be set. If time is rolled back within the same
interval, the record contains more than a full interval’s worth of data and the bit before the most
significant bit (bit 6) of the minute byte will be set.
Q
The remaining bytes are the values requested by the Historical Log 1 Data Pointers (45205-45332).
If the first Data Pointer is requesting V
BN
a 4 byte value, then the next 4 bytes in the Record are V
BN
.
This continues, Data Pointer for Data Pointer, until all Data Pointers have been satisfied, or the
number of bytes is equal to the Historical Log 1 Record Size.

Q
Historical Log 2: Historical Log 2 will fill to the total allocated memory. The number of records
possible in Historical Log 2 is the total memory allocated divided by the record size (size of a
Historical Log 2 snapshot).
