. . . 13 records
NOTES
:
• This retrieves the actual window. Repeat this command as many times as necessary to retrieve
all of the records when auto-increment is enabled.
• Note the filler record. When a log is reset (cleared) in the meter, the meter always adds a first
"filler" record, so that there is always at least 1 record in the log. This "filler" record can be iden-
tified by the data being all 0xFF, and it being index 0. If a record has all 0xFF for data, the time-
stamp is valid, and the index is NOT 0, then the record is legitimate.
• When the "filler" record is logged, its timestamp may not be "on the interval." The next record
taken will be on the next "proper interval," adjusted to the hour. For example, if the interval is 1
minute, the first "real" record will be taken on the next minute (no seconds). If the interval is 15
minutes, the next record will be taken at :15, :30, :45, or :00 - whichever of those values is next
in sequence.
6. Compare the index with Current Index.
NOTES
:
• The Current Index is 0 at this point, and the record index retrieved in step 5 is 0: thus we go to
step 8.
• If the Current Index and the record index do not match, go to step 7. The data that was received
in the window may be invalid, and should be discarded.
7. Write the Current Index to [0xC351, 2 reg].
