1.7 Transferring Data Files from the DX
The display and event data files, report data files, snapshot data files, setup files, and
change settings log files created in the internal memory of the DX can be automatically
transferred using FTP at the time the files are created.
Files to Be Transferred via FTP
The display or event data files are automatically transferred to the FTP destination
described in the next section at appropriate times.
File Type Description
Display data file Data files are automatically transferred at each file save interval.
Event data file Files are automatically transferred when the data length of data is
recorded.
Report data file When the file division mode is Combine † or Separate, † data files are
automatically transferred when a report file is closed (or divided).
For example, data files are transferred once per month when
generating only daily reports.
When the mode is Seprt2, † an individual report file is output for each
event.
† See section 9.5 in the DX1000/DX1000N or DX2000 User’s
Manual.
Snapshot data file The files are automatically transferred when a snapshot is executed.
They are transferred regardless of the media storage setting.
* Indicates snapshot using the FUNC key, communication command
(EV2 command), USER key, or remote control function.
Setup file and change
settings log file when the
settings have changed *2
The DX automatically transfers the setup file and change settings
log file that are automatically saved to the CF card when the settings
are changed.
*1 When “FTP transfer at signing” is enabled on a DX with the /AS1 advanced security option,
this file is automatically transferred after you sign in. See section 2.1 in the Advanced
Security Function (/AS1) User’s Manual.
*2 Only on DXs with the /AS1 advanced security option
Shifting the Transfer Time (Release number 3 or later)
There may be cases when data cannot be transferred from the DX to the FTP server
due to too many simultaneous connections to the FTP server. An example is when
multiple files are created and need to be transferred at the same time from multiple DXs.
By shifting the transfer time, you can avoid having too many simultaneous connections
to the FTP server. The time that display data files, event data files, and report files are
transferred can be shifted.
• Even if a new event that requires an FTP transfer occurs while the DX is waiting to
transfer the data of the previous event, it does not affect the transfer wait time of the
previous event. When the transfer shift time passes, all data files of the same type that
have been created (all of the files that have not been transferred) are transferred via
FTP. The following figure is an example for display data.
• To avoid accumulating too many files that have not been transferred, we recommend
that you set the transfer wait time shorter than the interval at which events that require
FTP transfers occur.
