BECKHOFF KL3311 - Manual (Page 14)

Register Description
12 KL3311, KL3312, KL3314 and KL3302
Terminal-specific register description
Process variables R0: Raw ADC value (X_R)
This register contains the unfiltered ADC value of the connected element
according to (Eq. 0.1)
(0x0000 corresponds to approx. -125mV, 0x8000 to approx. 0V, 0xFFFF to
approx. 125 mV, i.e. gain and offset errors are present)
R1 to R5: Reserved
R6: Diagnostic register
High byte: reserved
Low byte: status byte
Manufacturer parameters R17: Hardware compensation - offset (B_a)
16 bit signed integer
This register is used for offset compensation of the terminal (Eq. 1.2).
Register value approx. 0x0000
R18: Hardware compensation - gain (A_a)
This register is used for gain compensation of the terminal (Eq. 1.2).
Register value approx. 0x3D4X
R19: Manufacturer scaling - offset (B_h)
16 bit signed integer [0x0000]
This register contains the offset of the manufacturer's equation of the
straight line (1.6). The straight-line equation is activated via register R32.
R20: Manufacturer scaling - gain (A_h)
16 bits signed integer *2
-8
[0x00A0]
This register contains the scale factor of the manufacturer's equation of the
straight line (1.6). The straight-line equation is activated via register R32.
R21: Manufacturer gain compensation for reference voltage
[approx. 0x01XX]
