• Temporarily, following a failure of the primary FTP server.
The backup FTP server will then instantly take over the
role of the primary FTP server.
At the beginning of each new session, the SP90m checks
to see if the primary FTP server is back to work and
accessible. If that is the case, files will be pushed back to
the primary FTP server (and the backup FTP server will
stay idle in the background).
• Permanently, as a second repository for all the files
collected by the receiver.
Recording Raw
Data Outside of
Any Sessions
Raw data recording can also take place outside of any
sessions. What’s more, it can take place simultaneously with
data recording performed through the programmed sessions.
This alternate recording capability can be controlled through
Receiver
>
Memory
on the Web Server.
Like with sessions, this type of data recording produces a G-
file but the recorded data are those set on the port
corresponding to the storage medium used (and not on port S
or N). If for example the internal memory is used to save the
G-file, then the recorded data will be those set on port M.
The settings are very similar to, while independent of, those
found for session batches (i.e. site name, recording interval,
ring file memory). For example raw data can be collected at
1 Hz through sessions while those collected through the
Recording function may be at 20 Hz. Also a different site
name may be used so that you can easily identify the data
collected through the Recording function from those
collected through sessions.
As with sessions, the
Ring File Memory
option may be used in
this case to manage the free memory space. When this space
drops below
600
MBytes, the older raw data file will be
deleted to keep a minimum of free space on the storage
medium used.
