3 Data Log Settings Dialog Box
14-18 SmartAXIS Touch User’s Manual
■ Real Time
Select this check box to output data to the external memory in real time.
With real time output, data is saved to the external memory in three minute intervals after the Touch starts running.
When there is already data with the same file name on the external memory, data is appended to that file. If there
was no update to the data during the three minutes, it is not output.
Data is appended to the file until the size of the file reaches the restriction size (256 MB), so the maximum amount of output
data differs according to the settings for the output channel such as the amount of data, the data size, and the labels.
If the sampling interval is shorter than real time output (the interval for writing to the external memory), that Data
Log is recorded up to the data storage amount - 1, and then afterwards, old data is discarded in order and replaced
with new data.

Real time output stops when the file size of the Data Log data exceeds 256 MB or when there is insufficient
space on the external memory. USB flash drive error information is stored in
HMI Special Data Register
LSD33.
• When the value of HMI Special Internal Relay LSM18 changes from 0 to 1, the data at that time is first
output in real time to the USB flash drive, and then access to the USB flash drive is stopped.
• The text font configured for the starting device is output as the label font.
• You can check the free space on the USB flash drive with HMI Special Data Registers LSD34 to 35.
File Name: Enter the file name for the output data or shows the file name.
The default is “LOGAn.CSV”. (n: Data log channel number)
To change the file name, enter a new file name. The maximum number is 120 characters (including
the extension).
Add Device data to File Name
*1
:
Select this check box to add the bottom three digits of the
value of device configured by File Name Device to the end of
the file name for the output data.
Example: When the channel number is 1 and the value of
device configured by File Name Device is 123, the
file name is “LOGA01123.CSV”.
File Name Device: 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 2-62. This option can only be configured when the Add
Device data to File Name check box is selected.
• The function to sample data operates when Data Log data is being saved to the external memory.
• The methods to erase Data Log files saved on the external memory are as follows.
- To erase files during operation using parts, on the External Memory tab on the Project Settings dialog
box, select the Remove Files and the All Data Log files check boxes, and then configure the trigger
device. Assign that trigger device to a part.
- To erase files with WindO/I-NV3, click Clear on the Online tab, and then click Stored Data in
External Memory to display the Clear Data dialog box. Select the Data Log Data check box, and then
click OK.
