In this object an offset value for the correction of the A/D-value can be specified. The offset affects the<br />
objects 6401 h and 6402 h. Because the calculation with the offset is done before the addition or averaging<br />
of the measured values, it does only make sense to evaluate the 24 higher-order bits.<br />

7FFF FF00 +10,0 V - (1 LSBAD-CONVERTER) => 9.99999 V<br />
Note: If only the 16 higher-order bits of the A/D-converter values are used (object<br />
6401 h), then only the 16 higher-order bits of the 32-bit value of the object 2404 h<br />
are evaluated!<br />

1 LSB AD-CONVERTER => 10 V / 80 0000 h => 1.19209 V<br />
