This Register is an enumeration for the size of a record in the Historical Log. The valid values are:
0x00000 = 32 byte records
0x00001 = 64 byte records
0x00002 = 128 byte records
0x00003 = 256 byte records
0x00004 = 16 byte records
Q
Historical Log 2 Data Pointers: (45333-45460)
These Registers indicate which information to include in a record in the Historical Log. Each Data
Pointer has the following 4 (four) byte structure:
Size Format Description
2 byte unsigned int Line Number
1 byte unsigned char Point number
1 byte unsigned char Reserved
A Line Number is an index into the Communication Table. Example - Line Number 11 is for the 12th
line in the Communication Table, 0.1 second Phase-to-Neutral Voltages. Data Pointers with Line
Numbers greater than the number of lines in the table are ignored.
A Point Number is an index into the Communication Table.
Example: Point Number 1 is for the second entry in a Line. Line Number 11, Point Number 1 is the
second in the twelfth line, 0.1 second V
BN
. Data Pointers with Point Numbers greater than the number
of points for the line are ignored.
Q
Record Format: A Record contains as many bytes as specified by the Historical Log 2 Record Size
Field in the Programmable Settings Block (45464). 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.
