. . . 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 MP200 unit, the MP200
unit always adds a first "filler" record, so that there is always at least 1 record in
the log. This "filler" record can be identified by the data being all 0xFF, and it being
index 0. If a record has all 0xFF for data, the timestamp 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 registers].
