Cause : The calculated parameter checksum does not match any enabled reference checksum.
Programmable warning:
96.54 Checksum action
1. Check that all necessary approved (reference) checksums (96.71...96.72) are enabled in 96.55 Checksum control word.
2. Check the parameter configuration.
Using 96.55 Checksum control word, enable a checksum parameter and copy the actual checksum into that parameter.
