Boot Project Download Error

Hva betyr E2-28 ?

An error occurred during the download of the boot project to the Safety PLC. This prevents the PLC from loading its operational program correctly and entering a run state, rendering it inoperative.

• Corrupted boot project file on the engineering workstation or during transfer to the SM560-S Safety PLC's non-volatile memory.
• Intermittent or unstable communication link (e.g., loose Ethernet cable, network interference) between the engineering workstation and the Safety PLC during the download process.
• Insufficient free memory or a corrupted memory sector within the Safety PLC's non-volatile memory preventing the boot project from being written correctly.
• Incompatible boot project version with the current firmware of the SM560-S Safety PLC, leading to a download rejection.
• Hardware defect in the SM560-S Safety PLC's memory controller or communication interface preventing successful download.

1. 1

   1. Verify the integrity of the boot project file on the engineering workstation; attempt to download a different, known-good boot project if available.

2. 2

   2. Replace the Ethernet cable connecting the engineering workstation to the SM560-S Safety PLC's programming port with a known good, certified Cat5e or Cat6 cable.

3. 3

   3. Perform a power cycle of the SM560-S Safety PLC and retry the boot project download immediately after it restarts.

4. 4

   4. If the Safety PLC has a removable memory card, replace it with a new, compatible card, then attempt to download the boot project.

5. 5

   5. Connect to the Safety PLC via engineering software and try to clear its memory (e.g., perform a 'reset to factory settings') before attempting another download.

6. 6

   6. If repeated attempts fail after all software and hardware checks, replace the SM560-S Safety PLC CPU module.
