Data Log Function
Add Device Address data to File Name: Select this check box to add the bottom three digits of
the value of the device address configured by (File
Name Device Address) to the end of the file name for
the output data.
(File Name Device Address): Specifies the word device that is the source for the value to
add to the file name. For the device address configuration
procedure, refer to Chapter 2 “5.1 Device Address Settings”
on page 2-68. This option can only be configured when the
Add Device Address data to File Name check box is
selected.
Example: When File Name is "LOGO01" and the value of device address in (File Name
Device Address) is 123, the file name is "LOGO01123.CSV".
Add Time Stamp: Select from the following format for date and time to be added to the file
name when data is output:
None , YY , YY+MM , YY+MM+DD , YY+MM+DD+HH ,
YY+MM+DD+HH+MM , YY+MM+DD+HH+MM+SS
The format is YYMMDD_hhmmss (YY: year, MM: month, DD: day, hh: hour,
mm: minute, ss: second).
Example: File Name is "LOGO01" on September 15 2013 at 23:30:50
YY : LOGO01_13
YY+MM : LOGO01_1309
YY+MM+DD : LOGO01_130915
YY+MM+DD+HH : LOGO01_130915_23
YY+MM+DD+HH+MM : LOGO01_130915_2330
YY+MM+DD+HH+MM+SS : LOGO01_130915_233050
Set limit on files: Specifies the upper limit (1 to 100) when limiting the number of files to be
output.
When the Set limit on files check box is selected, note the following points.
• If the number of data files saved on the external memory device increases, it may take some time for
the data output processing, or the output of the next data may not be processed normally.
• When displaying pictures saved on the external memory device and processing the output of data both
occur simultaneously, the pictures may not be displayed.
• When parts that blink overlap pictures saved to the external memory device, the blinking period may
slow down when data output processing occurs.
• The following single-byte character cannot be used in the file name configured by File Name or Specify
File Name by Value of Device Address .
\ /
: ; * ? " < > |
• File names that exceed the limits in Specify File Name by Value of Device Address and file names
configured with characters that cannot be used are as follows.
- When the text of the file name exceeds the maximum number of device addresses (no NULL), the text
stored in device addresses up to the maximum number of device addresses from the start is
configured.
- When a character that cannot be used is set, the text is up to that character.
- When the first character is a character that cannot be used, the text is that set for
File Name .
• The operation when the Set limit on files check box is selected is as follows.
- The files are output up to the set limit, and then for additional files, the new files are saved by
discarding the old files in order of the oldest first.
- If the number of files saved on the external memory device already exceeds the limit when operation
starts, the number of files at that time is the limit. From there the data is discarded in order from the
oldest data and replaced with new data with each file output.
