■2. Background processing stop
By the background processing stop signal (GS522.b0), background processing by other functions (alarm, logging,
device monitoring) can be stopped during the backup/restoration.
When background processing is performed, the backup/restoration and other functions are alternately performed.
Therefore, backup/restoration takes much time, but the monitoring of the controller continues.
When background processing is not performed, processing of other functions stop until the backup/restoration is
completed.
Therefore, the monitoring of the controller stops, but the backup/restoration takes less time.

(1) Log file save setting
Before background processing is stopped, set the file saving for the functions that collect log
data such as the alarm and logging.
Without setting the file saving, all log data such as alarm data and logging data are lost after
backup/restoration is completed.
(2) Functions disabled during background processing stop
When background processing is stopped, in the backup/restoration, all functions stop except
for the backup/restoration.
Therefore, the following functions that collect log data cannot acquire the data in the backup/
restoration.
• Alarm function
• Operation log function
• Logging function
• Recipe function
(3) Background processing stop for trigger backup
During the trigger backup, turning on the background processing stop signal (GS522.b0)
does not stop background processing.
Background processing is always performed.
・
When background processing is stopped
Other functions stops communication until backup/restoration is completed.
