• SavingDatathroughKeyOperation
You can carry out the following data save operations regardless of whether auto save
or manual save is used.
DataStorage Description
All save Collectively saves all the data in the internal memory.
Selective save Saves the specified display data or event data file.
Manual sampled data save Collectively saves all the manual sampled data in the internal
memory.
Report data save Collectively saves all the report data in the internal memory.
 SaveDestination
You can select a CF card or USB flash memory (/USB1 option).
 DataSaveDestinationDirectory
Creates a directory with the name of the data save destination directory name with the
date/time added and saves the data.
Directory name: “Specified string”_YYMMDD_HHMMSS
Example: If the data is saved at 17 hours 6 minutes 42 seconds on September 30,
2005, the data is saved to a directory named “DATA0_050930_170642.”
“DATA0” is the specified string.
Note
The number of directories that you can create on the external storage medium varies
depending on the length of the directory names. If the length of the “specified string” is 5
characters, approximately 170 directories can be created. If it is 20 characters, approximately
120 directories can be created. An error occurs, if you try to create directories exceeding this
limit.
OtherTypesofDataThatCanBeStored
• SetupData
The setup data of the DX is saved to a CF card or USB flash memory (/USB1 option).
The setup data is saved to the root directory.

Example: ABCD10005.PDL
Name of the setup data file
• SnapshotData
The screen that the DX displays is saved to a CF card or USB flash memory (/USB1
option) in PNG format. The data is saved to the same directory as the display data
and event data. For the file name, see the previous page.

• CustomDisplaySetupData
See the Custom Display User’s Manual, IM04L41B01-04E.
SavingDataviatheEthernetNetwork
Display data, event data, report data (/M1 or /PM1 option), and screen image data
(snapshot data) can be automatically transferred and saved to an FTP server via the
Ethernet network by using the FTP client function. Conversely, the DX can function as an
FTP server. The DX can be accessed from a PC and the data files in the internal memory
or the external storage medium can be retrieved to be stored on the PC.
See the Communication Interface User’s Manual, IM 04L41B01-17E.
