KL3224 33 Version: 2.0.0
Output format
If only manufacturer scaling via the feature register is active, the output format is as follows:
1 digit is equivalent to 1/10 °C or
1 digit is equivalent to 1/10 Ω
If no scaling is active, the output format is as follows:
1 digit is equivalent to 1/16 °C or
1 digit is equivalent to 1/16 Ω
If the Siemens output format is selected, the lowest three bits are used for status evaluation. The process
data is mapped in bits 3 to 15, with bit 15 representing the sign bit. Scaling of the measurement reading
according to the Siemens standard has to be done via user scaling.

R33 to R47: Terminal-specific registers
The function of these registers depend on the respective terminal type (see terminal-specific register
description).
R33: User scaling – offset (B_w)
16-bit signed integer
This register contains the offset of the user straight-line equation (1.6). The linear equation is enabled via
register R32.
R34: User scaling (A_w)
16-bit signed integer * 2-
8
. This register contains the scaling factor of the user straight-line equation (1.6).
The linear equation is enabled via register R32.
R35 and R36: reserved
R37: Filter constant
[0x0000]
This documentation applies to all terminals from firmware version 3x. The version number can be found
within the serial number on the right-hand side face of the terminal: xxxx3xxx
Example: 5298 3A 2A = the firmware version is 3A.
