Overrange protection is active:
If the limit values of registers OvRL (R21) and UnRL (R22) are exceeded, the associated
status bits are set and the measuring range is restricted accordingly.

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).
