Calculation of the Checksum (CS) and the Weighted Checksum (gewCS)
The calculation takes place via all parameter bytes (without the command byte). At the CS all bytes are added (overflows
are not considered here). For the calculation of the gewCS the CS is added to the gewCS. At overflow the gewCS is
incremented by 1.
