When restoring a file backup, what happens to the SRAM files on the controller?

When restoring a file backup on a FANUC controller, SRAM files are overwritten. This means that the files stored in SRAM, which include the current configuration and any operation-related data, will be replaced with the data from the backup file. This action is crucial for ensuring that any previous settings or configurations are updated or reverted to a specific known state as defined in the backup.

This overwriting process can be essential in various scenarios, such as recovering from an error or ensuring consistency across multiple systems. Understanding this is key when managing controller backups, as it emphasizes the importance of keeping current records of SRAM files before performing a restore operation. Performing a backup of SRAM files before restoring can safeguard any critical data that might be lost in the process.
