5.6.4 FLD File
(Read)
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;23/04/14;100
Asks for 100 records from the 23 th of April 2014 at 18:13.
If, instead, the string would have been FLD
18:13;23/04/14;---
It would ask for all records from the 23 th of April 2014 at 18:13 up to now.
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 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 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.
5.6.5 Record File
(Write)
After having read the FLD file, which informs the AMS-8061 about which
records
have to be uploaded, it writes a file named
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
The content of this file is binary and reflects what is described, according to
the setting, in the §3.11 “D61 Structure, Download description
”.
Please
refer to it for the correct interpretation of data.
