ABB PM554: Troubleshooting Target Profile Mismatch

Identify the PM554 Mismatch

The reported serial connection attempt to a PM554 stops with a message translated as “The source profile does not match the target system.” This indicates a project-to-controller identity mismatch. The available evidence does not identify a serial wiring or communication-parameter fault.

Confirmed Root Cause

The error occurs when the project is configured for a CPU model other than the connected controller. The project CPU selection must match the PM554 before downloading.

Correct the Project Configuration

1. Open the project hardware or CPU configuration.
2. Check the configured CPU model against the physical PM554.
3. Change the project configuration to the matching CPU model if another model is selected.
4. Retry the project download through the serial connection.

Do not treat firmware as the primary correction unless the CPU model already matches and separate product documentation identifies a firmware compatibility requirement.

Verify the Correction

Repeat the same connection and download operation after correcting the CPU selection. The correction is verified when the controller accepts the project without the source-profile-versus-target-system mismatch. If the message remains, recheck the exact physical CPU model and the project target before investigating unrelated serial communication issues.
