Register description
KL3351 11
Terminal-specific register description
Process variables R0: Unfiltered ADC value X_R
This register contains the unfiltered ADC value of the connected element
according to (Gl. 0.1)
R1-R5: No function
R6: Diagnostic register
High byte: not used
Low byte: status byte
Manufacturer parameter R17: Offset hardware B_a
16 bit signed integer
This register is used for offset compensation of the terminal.
Register value approx. 0x0000
R18: Gain hardware A_a
This register is used for gain compensation of the terminal.
Register value approx. 0x3D4X
R19: Manufacturer offset B_h
16 bit signed integer [0x0000]
This register contains the offset of the manufacturer’s linearisation
equation. The linearisation equation is activated by way of R32.
R20: Manufacturer scaling A_h
16 bit signed integer *2^-8 [0x00A0]
This register contains the scale factor of the manufacturer’s linearisation
equation. The linearisation equation is activated by way of R32.
Application parameter R32: Feature register:
[0x0004]
The feature register specifies the terminal’s operating mode.
Feature Bit No. Description of the operating mode
Bit 0 1 User scaling (R33, R44) active [0]
Bit 1 1 Manufacturer scaling (R19, R20) active [0]
Bit 2 1 Watchdog timer active [1]
The watchdog timer is switched on by default.
Bit 3 1 Sign / amount representation [0]
Sign / amount representation is active instead
of twos-complement representation. (-1 =
0x8001)
Bit 4 - Not used, don’t change
Bit 5 1 activate Filter constant in R37 [0]
Bit 11-6 - Not used, don't change
Bit 15-12 Operating mode
1111 Voltage output [1111]
others Reserved
R33: User offset B_w
16 bit signed integer
This register contains the offset of the user linearisation equation. The
linearisation equation is activated by way of R32.
R34: User scaling A_w
16 bit signed integer *2^-8
This register contains the scale factor of the user linearisation equation.
