Alarm Log Function
■
Real Time
Select this check box to output data to the external memory device
*1
in real time.
With real time output, data is saved to the external memory device
*1
in three minute intervals after the MICRO/I
starts running. If the accumulated data reaches 819th item, then the data is forcibly saved to the external memory
device
*1
. When there is already data with the same file name on the external memory device
*1
, 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 external memory
device), 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 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 33-7.

• When the value of the following HMI Special Internal Relays changes from 0 to 1, the data at that time is
first output in real time to the external memory device, and then access to the external memory device is
stopped. For details, refer to Chapter 33 “HMI Special Relay (LSM)” on page 33-2.

• The amount of free space on the external memory device is saved to the following HMI Special Data
Registers. For details about the free space on the External Memory Devices, refer to Chapter 33 “HMI
Special Data Register (LSD)” on page 33-7.

Trigger Condition: Select the check boxes for the items that will trigger the output of Alarm Log data to the external memory
device.
Occurrence:
Alarm Log data is output to the external memory device when an alarm has
occurred.
Recovery: Alarm Log data is output to the external memory device when the alarm is
recovered from.
Confirmation: Alarm Log data is output to the external memory device 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.
