■ Real Time
Select this check box to output data to the memory card in real time.
With real time output, data is saved to the memory card in three minute intervals after the MICRO/I starts running.
For the HG2G-5F and the HG3G/4G, if the accumulated data reaches 819th item, then the data is forcibly saved to the
memory card. When there is already data with the same file name on the memory card, 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 varies based on the settings for the output channel such as the amount of data, the data size, and the labels.
If the interval to update the Alarm Log is shorter than real time output (the interval for writing to the memory card), that Alarm
Log is recorded up to the 1023rd item, and then afterwards, old data is discarded in order and replaced with new data.

Real time output stops when the file size of the Alarm Log data exceeds 256 MB or when there is insufficient
space on the memory card. Memory card error information is stored in HG special register LSD42.
• When the value of HG special relay LSM20 changes from 0 to 1, the data at that time is first output in real
time to the memory card, and then access to the memory card is stopped.
• You can check the free space on the memory card with HG special registers LSD43 to 44.
Trigger condition: Select the check boxes for the items that will trigger the output of Alarm Log data to the memory card.
Occurrence: Alarm Log data is output to the memory card when an alarm has occurred.
Recovery: Alarm Log data is output to the memory card when the alarm is recovered from.
Confirmation: Alarm Log data is output to the memory card when the key button CHECK was pressed.
Month/day/year hour:minute:second is output for the trigger condition occurrence time, recovery time, and
confirmation time.
File Name: Enter the file name for the output data or shows the file name.
HG2G-5F, HG3G/4G: The default is “ALMHTA.CSV”. To change the file name, enter a new file
name. The maximum number is 120 characters (including the
extension).
HG2F/3F/4F: The file name is “ALMHTA.CSV”. This cannot be changed.
Specify File Name by Value of Device *1*2 :
Select this check box to specify the name of the file for the output data with the value of the
device configured by (File Name Device).
(File Name Device): Specifies the word device that is the source of the data to use as the file
name. The file name is set by reading the values sequentially from the
starting device specified with the file name device and handling those
values as character data up to the character before NULL (00).
The maximum number of devices is 40 (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 2-67.
Example: When the device specified by (File Name Device) is LDR100 and the text to set is "IDEC":
The file name at this time becomes "IDEC.CSV".
