4.4.4.4 FLD File
(Write)
After having dealt with the configuration file 8061.CFG, the AMS-8061
check for the presence of a file named 8061FLD.TXT.
This, is an ASCII file which contains the date of the first requested record
and the number of them. The syntax is: FLD HH:mm;GG/MM/YY; n where:
•
HH is hour of the day.
•
mm is minute of the day.
•
GG is the day.
•
MM is the month.
•
YY is the year
•
n is the number of records required (if n="---" then all records
starting from the date/hour up the last recorded record will be
uploaded).
For example the string FLD 18:13;23/07/09;100
Asks for 100 records from the 23
If, instead, the string would have been FLD 18:13;23/07/09;---
It would ask for all records from the 23
Note that, in case of "---" (up to now option), in order to avoid huge
files and long transfer time, the number of records will be limited to
about 5000.
Once the AMS-8061 has read the file 8061FLD.TXT, it deletes it. It will be
replaced later with the newer self created 8061FLD.TXT which reflects the
last uploaded record.
This solves the continuity of records even without any external intervention.
Indeed, for every connection the AMS-8061 uploads the records and writes
a new FLD file which reports the date/hour of last record so that next
connection will continue from this having thus an uninterrupted series of
records.
After having read the FLD file, which informs the AMS-8061 about which
records
have
to
HH_mm_GG_MM_YY.D61 where:
•
HH is hour of the day.
•
mm is minute of the day.
•
GG is the day.
•
MM is the month.
•
YY is the year
This file, in binary format, contains the downloaded measurement results.
After having written the record file HH_mm_GG_MM_YY.D61, the AMS-
8061 writes the file named 8061FLD.TXT which replaces the old one.
This, is an ASCII file which contains the date of the last uploaded record
and terminates with the string "---".
The content will be therefore: FLD HH:mm;GG/MM/YY;---
•
HH is hour of the day.
•
mm is minute of the day.
•
GG is the day.
•
MM is the month.
•
YY is the year
For example the string FLD 20:30;23/07/09;---
Says that the last updated record is related to the date of 23th of July 2009
at 20:30 .
If the user does not need a specific period but, as usual, a simple
continuous data logger , there is no need to write any FLD File as the
system is self-sufficient.
