output.
R22: Under range limit: UNRL
16 bit signed integer in Y_a Gl.1.0 [0x0000]
If the actual value drops below this limit, the corresponding status bit is set
and the minimum value is output.
R23: ADC-Hardware preset
[0x1000]
Initialization of the ADC offset register.
Application parameters
R32: Feature register:
[0x1106]
The feature register determines the operating modes of the terminal.
Feature Bit No.

User scaling (R33, R44) active [0]
Bit 1

Manufacturer scaling (R19, R20) active [1]
Bit 2
1
Watchdog timer active [1]
By default, the watchdog-timer is on.
Bit 3
1
Signed amount representation [0]
The signed amount format is active instead of
the 2’s complement. (-1 = 0x8001)
Bit 4
1
Siemens output format [0]
With this bit, status flags are inserted in the 3
least significant bits (see below).

Bit 8
1
Over range protection [1]
If values exceed or fall below the limits of the
registers OVRL (R21), UNRL (R22), the status
bits are set accordingly and the measured range
is appropriately restricted.
Bit 9
1
Limit 1 active [0]
The process data is compared against limit 1
(R35) and corresponding status bits are set.
Bit 10
1
Limit 2 active [0]
The process data is compared against limit 1
(R36) and corresponding status bits are set.
Bits 15-11
-
not used, don't change
The three least significant bits are used for status evaluation if the Siemens
output format is chosen. The process data item is mapped in bits 3-15, and
bit 15 is the sign bit. The scaling of the process data in accordance with the
Siemens-format must take place over the user scaling (R33, R34)

R33: User-Offset B_w
16 bit signed integer
This register contains the offset of the user straight-line equation (1.4). The
straight-line equation is activated via R32.
R34: User scaling A_w
16 bit signed integer * 2^-8
This register contains the scaling factor of the user straight-line equation
(1.4). The straight-line equation is activated via R32.
R35: Limit 1 in Y_2
If the process data exceeds or falls below this limit, the corresponding bits
