Functional description
KL304x and KL305x 5
Process data The process data that are transferred to the Bus Coupler are calculated
using the following equations:
X_adc: Output values of the A/D converter
Y_aus: Process data to PLC
B_a,A_a: Manufacturer gain and offset compensation (R17, R18)
B_h,A_h: Manufacturer scaling (R19, R20)
B_w,A_w: User scaling (R33, R34)
a) Neither user nor manufacturer scaling are active:
Y_a = (B_a + X_adc) * A_a (1.0)
Y_aus = Y_a
b) Manufacturer scaling active (factory setting):
Y_1 = B_h + A_h * Y_a (1.1)
Y_aus = Y_1
c) User scaling active:
Y_2 =B_w + A_w * Y_a (1.2)
Y_aus = Y_2
d) Manufacturer and user scaling active:
Y_1 = B_h + A_h * Y_a (1.3)
Y_2 = B_w + A_w * Y_1 (1.4)
Y_aus = Y_2
The equations of the straight line are activated via register R32.
