What type of memory is saved when performing an image backup on a FANUC controller?

When performing an image backup on a FANUC controller, both F-ROM (Flash ROM) and SRAM (Static Random Access Memory) are preserved.

F-ROM is significant because it contains the firmware and system software critical for the operation of the controller, ensuring that any settings or configurations saved in this memory can be restored in case of a system failure or the need to reset the controller. By including F-ROM in the image backup, users can safeguard the baseline operational parameters and custom configurations that are essential for the controller's functionality.

SRAM, on the other hand, holds volatile data such as temporary variables and operational settings while the controller is powered on. It is crucial for storing real-time operational data needed for the current tasks being executed by the robot.

Because both types of memory play vital roles in the controller's operation, preserving them during an image backup ensures a comprehensive recovery of the system to its state prior to any issues, thus allowing for uninterrupted performance and easier troubleshooting in future operations.
