4.3.5 ARCHIVE CONFIGURATION (Cont.)
ARCHIVE TO MEDIA
For ‘Local’ setting only:
None
Archive must be initiated by the operator (
section 4.1
)
Hourly
Archive occurs on the hour every hour
Daily
Archive occurs at 00:00* hrs each day
Weekly
Archive occurs at 00:00* hrs every Monday
Monthly
Archive occurs at 00:00* hrs on the 1st of each month
Automatic
The recorder selects the least frequent archive period (Hourly, Daily, Weekly, Month-
ly), which is guaranteed not to lose data as a result of either the internal Flash, or the
local memory device, running out of space (calculated assuming that the memory
device is initially ‘empty’). When Automatic is selected, a further, non-editable menu
item appears, showing which of the archive frequencies has been selected.
*Note: Archive times are not adjusted for Daylight Saving hour changes. Thus if the archive is set
to ‘daily’, ‘weekly’ or ‘ monthly’ then, during ‘Summer Time’, the archive will occur an hour late (i.e.
at 01:00 hrs. instead of midnight).
MEDIA FILE FORMAT/FTP FILE FORMAT
Allows ‘Binary’ (.uhh) fi les, ‘CSV’ (.csv) fi les or ‘Binary and CSV’ to be chosen for FTP transfer. For further
details of
CVS
archiving, see description at the end of this subsection (4.3.5).
ON MEDIA FULL
For ‘Local’ setting only:
Overwrite
Oldest data is replaced with latest data when storage medium is full.
Stop
Archiving stops when the storage medium is full.
Note: When in ‘Overwrite’ mode, the recorder will overwrite only those fi les which it has itself
created. Thus, if a storage medium is inserted which contains history fi les from another recorder,
these cannot be overwritten. The fi le names are of the form UUU....UUUIIIIIIFFGGSSSSSS, where
IIIIII represent the lowest three bytes of MAC address of the recorder which created the fi le (see
section 4.5.1
). It is not possible for the user to delete fi les created by another instrument (i.e. one
with a different MAC address).
Note: The ‘Overwrite’ mode is limited (to approximately 2000 fi les), therefore it depends on the
correct storage medium capacity. The recommended storage medium size is 1GB. If the storage
medium size is increased users should consider using the ‘Stop‘ mode in conjunction with the ‘Me-
dia Full Event Limit’ function to provide a sustainable method for larger archives of data.
MEDIA SIZE
For ‘Local’ setting only, this displays the capacity of the memory device.
REMOVABLE MEDIA CAPACITY
For ‘Local’ setting only, this gives an estimated time to fi ll the archive medium, based on the archive rate,
the compression ratio, the storage medium size and on the exact nature of the data. (Rapidly changing
values use more space than static/slowly changing values.) When archiving to Floppy disks (via USB port),
this fi eld remains empty until after the fi rst archive has taken place.
MEDIA FULL EVENT LIMIT
For ‘Local’ setting only, this allows the user to specify a percentage-full value for the storage medium,
at which the event source ‘Archive media % full’ is triggered. The event remains active until the storage
medium is replaced, or has data removed from it to make more room available.
