E3-45

Boot Project Load Failed (Retain Data Mismatch)

ABB · System

What does E3-45 mean?

The CPU failed to load the boot project because the retain data detected does not match the project's requirements. This mismatch can occur after firmware updates or project changes, causing the CPU to reject the current configuration and potentially halting operation. Data consistency is crucial.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Consult the manual for proper migration steps after firmware or project changes to ensure data consistency.

  2. 4

    If the problem continues, ensure the boot project itself is not corrupted.
