RP controller expansion modules have two types of memory, flash memory and RAM.
The flash memory is used as follows:
Embedded flash memory: for boot loader, operating system, application software, and configuration storage
NOR flash memory: for log files and default configuration storage
The RAM is used for runtime operation.
The configuration data for the RP controller expansion modules resides in the RP controller to which the devices are connected. When the RP controller is part of an EcoStruxure BMS, the configuration data for the controller and expansion modules automatically resides in the parent EcoStruxure BMS server. Any configuration changes made through the EcoStruxure Building Operation software are stored in the EcoStruxure BMS server as well as the hosted RP controller and its subsystem. This means there is always a backup available for restoring or replacing an RP controller.
Configuration changes made through a third party BACnet Operator Workstation (B-OWS) or the Commission mobile application are not automatically part of the configuration data in the EcoStruxure BMS server. You need to upload such configuration changes if you want the changes to be stored in the EcoStruxure BMS server.
Scheduled backups of the EcoStruxure BMS server can provide additional protection against application and data loss. You can also manually back up or restore an EcoStruxure BMS server to a storage location on a PC or network.
