Register Description
12
KL304x and KL305x
R33: User scaling - 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 register R32.
R34: User scaling - gain (A_w)
16 bits signed integer* 2
-8
This register contains the scale factor of the user straight-line equation
(1.4). The straight-line equation is activated via register R32.
R35: Limit value 1 in (Y_2)
If the process data are outside this limit value, the appropriate bits are set
in the status byte.
R36: Limit value 5.08 cm (Y_2)
If the process data are outside this limit value, the appropriate bits are set
in the status byte.
R37: Filter constant
[0x0000]
i
Note
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: 52983A2A
⇒
The firmware version is 3A.
If the internal filter is activated via R32.11, the following filter constants can
be selected in R37 (not possible for KL3044 and KL3054). In the standard
setting, the corresponding conversion time is 2.5 ms:

Explanation
0x0000
2nd order FIR filter.
default value
0x0100
1st order IIR filter, cut-off frequency f
g
approx.1 kHz
0x0200
1st order IIR filter, cut-off frequency f
g
approx. 100 Hz
0x0300
1st order IIR filter, cut-off frequency f
g
approx. 50 Hz
0x0400
1st order IIR filter, cut-off frequency f
g
approx. 20 Hz
0x0500
1st order IIR filter, cut-off frequency f
g
approx. 10 Hz
0x0600
1st order IIR filter, cut-off frequency f
g
approx. 5 Hz
0x0700
1st order IIR filter, cut-off frequency f
g
approx. 1 Hz
The implemented IIR filters do not
have any notch behavior, i.e., they do
not explicitly suppress any frequency.
0x1000
50 Hz FIR filter
Averaging over 16 values and first notch 25 Hz
0x2000
60 Hz FIR filter
Averaging over 16 values and first notch 20 Hz
In contrast to the IIR filters, FIR filter
have notch behavior. The timer
settings of the notch filters are set via
channel 0 of the terminal. This means
that the 50 Hz filter on channel 0 and
the 60 Hz filter on channel 1 cannot
be active simultaneously.

values
