Siemens output format
If the Siemens output format is selected, the lowest three bits are used for status evaluation. The process
data is represented in bits 15 to 3, with bit 15 representing the sign bit. Scaling of the measured value
according to the Siemens standard has to be done via user scaling (R33, R34).

R33: User scaling for analog input - offset (B
w
)
This register contains the offset of the user scaling for the analog input (default: 0).
User scaling for the analog input can be activated in the feature register via bit
