CPU Restore Failed

Was bedeutet E2-49 ?

A restore operation on the CPU, likely involving configuration or application data, has failed. This can lead to the CPU operating with incorrect settings, an older configuration, or failing to start completely, compromising the intended system functionality. Data integrity is at risk.

• Corrupted backup image or restore file being used (e.g., .rdb file).
• Insufficient free memory on the CPU for the restore operation.
• Interruption during the restore process (e.g., power loss, communication error).
• Firmware version mismatch between the backup image and the current CPU firmware.
• Hardware defect in the CPU's non-volatile memory (e.g., NAND flash).

1. 1

   1. Verify the integrity of the restore file using a checksum utility if available.

2. 2

   2. Ensure the CPU has sufficient free internal memory (e.g., check via diagnostic buffer).

3. 3

   3. Perform the restore operation again, ensuring a stable power supply and communication link.

4. 4

   4. Compare the firmware version of the CPU with the firmware version on which the backup was created.

5. 5

   5. Perform a factory reset of the CPU before attempting the restore operation.
