5.4.2 Alarm buffer
Under "Alarm buffer" you can activate or deactivate the retentive alarm buffer. The default
setting is "deactivated".
Note
Back up data before deactivating the retentivity
When you deactivate the retentivity of the alarm buffer and still need the data in the alarm
buffer, back up this data before deactivating the retentivity in a
log.
Alarm buffer configuration
● "Storage media": Selection list for defining the storage medium for the retentive alarm
buffer. Selection options:
– "Internal Memory": Alarms are written to the internal flash memory.
● "Enable alarm buffer": Option to enable or disable the retentive alarm buffer. The default
setting is "deactivated".
When the retentivity of the alarm buffer is activated, the retentive alarm data is backed up
every two seconds to the selected storage medium. With a high number of alarms, the
storage medium is subject to an equally high number of read and write cycles.
If the retentivity of the alarm buffer is deactivated, the alarm buffer is emptied and the
retentive alarm data is no longer backed up to the selected storage medium. This means
the storage medium is used less with a high number of alarms.
Switching the "Enable alarm buffer" option requires a restart, the "Enable alarm buffer"
dialog is displayed. Restart the system using the "OK" button.
