Data Log Function
■ Batch
Select this check box to batch output all the sampled data to the external memory device
*1
.
All the data is saved on the external memory device

when the trigger device addresses changes from 0 to 1. If a file
with the same name already exists on the external memory device
*1
, that file is overwritten. The maximum amount of
output data is the amount configured by the data storage area.
*1 USB flash drive inserted in USB1 for HG2J-7U, SD memory card for HG5G/4G/3G/2G-V, HG4G/3G and HG2G-5F,

The storing of data stops if there is insufficient free space on the external memory device. The error
information is stored in the following HMI Special Data Registers. For details about the error information,
refer to Chapter 33 “HMI Special Data Register (LSD)” on page 33-8.

Trigger Device Address: Specifies the bit device or the bit number of the word device to serve as condition for batch
output. For the device address configuration procedure, refer to Chapter 2 “5.1 Device
Address Settings” on page 2-70.
Data is output to file when the value of the Trigger Device Address changes from 0 to 1.
File Name: Enter the file name for the output data or shows the file name.
The default is “LOGOn.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).
Specify File Name by Value of Device Address: Select this check box to assign a file name
for the output data using a value of device
address specified in the File Name Device
Address.
(File Name Device Address): Specifies a word device to create a file name. The file
name is set by reading the values sequentially from the
starting device address specified with the File Name
Device Address and handling those values as character
data up to the character before NULL(00h).
The maximum number of device addresses is 40
(2 characters per word device, maximum of 80 single-
byte characters). You can only specify an internal device.
For the device address configuration procedure, refer to
Chapter 2 “5.1 Device Address Settings” on page 2-70.
Example: from Upper byte is selected as the Storage Method of String Data on
the System tab in the Project Settings dialog box, and the device address
specified by (File Name Device Address) is LDR100 and the text to set is
"IDEC":
The file name at this time becomes "IDEC.CSV".
