BECKHOFF KL3102 - Manual (Page 12)

Register description
12 KL3102
Application parameters
R32: Feature register
[0x0000]
The feature register determines the operating modes of the terminal.
Feature Bit No. Mode description
Bit 0 1 User scaling (R33, R34) active [0]
Bit 1 1 Manufacturer scaling (R19, R20) active [0]
Bit 2 1 Watchdog timer active [0]
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)
Bits 7-4 - not used, don't change
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
R33: User-Offset B_w
[0x0000]
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
[0x0100]
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
[0x0000]
If the process data exceeds or falls below this limit, the corresponding bits
are set in the status byte.
R36: Limit 2 in Y_2
[0x0000]
If the process data exceeds or falls below this limit, the corresponding bits
are set in the status byte.
R37: Filter constant of the ADC
[35C0]
The KL3102 possesses two low-pass filter stages. The first level consists
of a sinc^3 filter. This is always active. Second consists of a FIR filter
22.order, which can be deactivated.
R37.0 Fast-Bit =1: It takes place a fast reaction to branches at the input
despite active filter stage. With branches the filter is gone around.
R37.1 Skip-Bit =1:
The FIR filter stage is deactivated.
SKIP=1
F_g = 81076 / Nf
SKIP=0
F_g = 11981 / Nf
F_stop = 43008 / Nf
