Bits 12 to 15
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 [} 37]).

+10 V

• R33: User scaling - offset (B_w)
16 bit signed integer
This register contains the offset of the user straight-line equation (Eq. 1.4 [} 12]). The straight-line
equation is activated via register R32 [} 37].
• R34: User scaling - gain (Aw_)
16 bit signed integer*2
This register contains the scale factor of the user straight-line equation (Eq. 1.4 [} 12]). The straight-line
equation is activated via register R32 [} 37].
• R35: Limit value 1 (Y_2)
If the process data are outside this threshold, the appropriate bits are set in the status byte.
• R36: Limit value 2 (Y_2)
If the process data are outside this threshold, the appropriate bits are set in the status byte.
• R37: Filter constant
[0x0000]
If the internal filter is activated via R32.11, the following filter constants can be selected in R37. In the
standard setting, the corresponding conversion time is 2.5 ms:

Description of the operation mode
1
User scaling (R33, R34 [} 37]) active [0]
1
Manufacturer scaling (R19, R20 [} 36]) active [1]
1 Watchdog timer active [1]
In the delivery state, the watchdog timer is switched on.
1 Sign / amount representation [0]
Sign / amount representation is active instead of two's-complement
representation. (-1 = 0x8001).
1 Siemens output format [0]
This bit is used for inserting status information on the lowest 3 bits (see
below).
- Reserved, don't change
1 Over range Protection [1]
If values exceed or fall below the limits of the registers OVRL (R21 [} 36])
and UNRL (R22 [} 36]), the status bits are set and the measuring range is
restricted accordingly.
1 Limit value 1 active [0]
The process data are compared with limit value 1 (R35 [} 37]), and
appropriate status bits are set.
1 Limit value 2 active [0]
The process data are compared with limit value 2 (R36 [} 37]), and
appropriate status bits are set.
1 Filter1 active [0]
For filter properties, see R37 [} 37]
