• Precautions for starting the GOT
When reading and restoring the user alarm from the data storage, install the data storage on the GOT
before powering-on the GOT.
After powering-on the GOT, the data in the data storage cannot be restored.
In addition, when the data storage is installed after the power-on, the user alarm data in the data storage
are overwritten when other user alarm data are stored in the data storage.
(b) Performing the power-failure backup
To hold the data in the data storage, configure the setting in the [File Save] tab of the [User Alarm
Observation] dialog, and use either of the following methods.
• Storage by the store trigger device
• Storage by the touch switch
• Storage by the Buffer Flash Forced Saving signal (GS520.b0)
To hold the data in the SRAM user area, configure the setting in the [Basic] tab of the [User Alarm Observation]
dialog.
• Saving data to the SRAM user area
(c) Information to be stored
The information in the alarm log file to be stored in the data storage and the SRAM user area differ
depending on the alarm collecting method.
(d) File name and storage timing
You can set any file name for each alarm ID.
You can set triggers (rise or fall) to perform the file save.
(e) Available memory capacity
The memory capacity used to retain the user alarms at power failure can be checked in the [Basic] tab of
the [User Alarm Observation] dialog.
(f) Backing up the alarm log file stored in the data storage
Select [Automatically backup at the time of saving] in the [File Save] tab of the [User Alarm Observation]
dialog to store the alarm log file as a backup file when the alarm log file is saved.
