7.5.2 Digital Output, RS422
7.5.2.1 Values, Ranges
The digital measuring values are being output as unsigned digital values (raw values). 16 resp. 18 bits per value are being transmitted.
Subsequently you can find a compilation of output values and the conversion of the digital value.

The output range is also coded with 64235
values at 18 bit and shifted with the master
value, see Fig. 37. The reserves at SMR
and EMR are coded with 643 values each.
