BACnet/IP devices have three types of memory:
Flash memory: for boot loader, operating system, application software, and configuration storage
RAM: for runtime operation
FRAM non-volatile memory: for data retention in the case of power outage
You can manually back up or restore BACnet/IP controller devices to a storage location on a PC or network. For more information, see BACnet Backup and Restore .
When BACnet/IP controller devices are part of an EcoStruxure BMS, the configuration data automatically resides in the parent EcoStruxure BMS server. The EcoStruxure Building Operation database and the BACnet/IP controller device database are synchronized to help ensure there is always one backup available that can be used to restore the BACnet/IP controller device memory. Scheduled backups can provide additional protection against application and data loss. In addition, device-specific values (for example, AHU or heat pump data) are duplicated in the parent server to facilitate device replacement scenarios.
