4.3.5 ARCHIVE CONFIGURATION (Cont.)
MEDIA FULL OPERATION
For Disk Settings only:
Overwrite
Oldest data replaced with latest data when disk is full.
Stop
Archiving stops when the disk is full.
Notes
1
For floppy disk recorders, the maximum number of history files (total for all groups) is 750 per directory.
For PCMCIA (memory card) recorders, the maximum number of history files per directory is 750 for
each group.
2
When in 'Overwrite' mode, the recorder will overwrite only those files which it has itself created. Thus,
if a disk is inserted which contains history files from another recorder, these cannot be overwritten. The
file names are of the form UUU....UUUIIIIIIFFGGSSSSSS, where IIIIII represent the lowest three bytes
of MAC address of the recorder which created the file (see section 4.5.1). It is not possible for the user
to delete files created by another instrument (i.e. one with a different MAC address).
MEDIA SIZE
For Disk Settings only, this displays the capacity of the Disk or PC card.
DISK ARCHIVE CAPACITY
For Disk Settings only, this gives an estimated time to fill the disk/pc card, based on the archive rate, the compression
ratio, the disk size and on the exact nature of the data. (Rapidly changing values use more space than static/slowly
changing values.)
MEDIA FULL EVENT LIMIT
For disk settings only, this allows the user to specify a percentage-full value for the disk or pc card, at which the
event source 'Archive media % full' is triggered. The event remains active until the disk or pc card is replaced, or has
data removed from it to make more room available.
ARCHIVE TO REMOTE
For Remote settings only:
None
Archive to host is initiated by the operator (
Hourly
Archive to host occurs on the hour every hour
Daily
Archive to host occurs at 00:00* hrs each day
Weekly
Archive to host occurs at 00:00* hrs every Monday
Monthly
Archive to host occurs at 00:00* hrs on the 1st of each month
Automatic
The recorder selects the slowest out of ‘Hourly’, Daily, Weekly or Monthly, which is guaranteed not to
lose data (depends on the size of the Trend History Buffer).
*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).
REMOTE PATH
For Remote settings only:
The route to a folder or directory on the remote host, set up as a part of that host’s FTP configuration
