RP and MP controllers and I/O modules are devices that 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 the devices to a storage location on a PC or network. For more information, see BACnet Backup and Restore .
When RP and MP controllers and I/O modules are part of an EcoStruxure BMS, the configuration data automatically resides in the parent EcoStruxure BMS server. The EcoStruxure Building Operation database and the device database are synchronized to help ensure there is always one backup available that can be used to restore the 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.
For VAV controllers, ensure you back up and save the flow balance data, as this data is not covered by the database synchronization described above.
