Issue
When backup to flash is automatically disabled by the system due to exceeding the flash circuit breaker write limit, no system alarm is sent to make the system's operator aware
Product Line
EcoStruxure Building Operation
Environment
Continuum i2920 Controller
Cause
Implementation of Continuum Infinet integration in EcoStruxure Building Operation did not include this feature.
Resolution
As a workaround, a user-created alarm can be used instead of the system alarm.
Here is a sample implementation of this workaround:
- Under the Infinet Interface create an Alarm, in this example, we are using an 'Expression' alarm
Here is the algorithm used as an expression for the alarm
Value = BackupDisabld
-
In the i2 device, edit the 'StatusBackup' system variable and attach the alarm above in the Alarm Configuration tab.
Make sure to tick the 'Enabled' box to engage the alarm.
The alarm will be sent when the flash circuit breaker trips which in the i2 device takes place after 10,000 backups
To resume backups the feature must be manually re-enabled from Workstation by right-clicking the device and selecting DEVICE->ENABLE BACKUP TO FLASH
