Cause : Checksum mismatch comes when the calculated parameter checksum does not match any enabled reference checksum.
- Check that all necessary approved (reference) checksums (96.56…96.59) are enabled in 96.55 Checksum control word.
- Check the parameter configuration. Using 96.55 Checksum control word, enable a checksum parameter and copy the actual checksum into that parameter.
