Product overview

KL320x

Version: 4.4

Process data

The process data that are transferred to the terminal bus are calculated using the following equations:

Variable

Meaning

X_RL

ADC value of the supply cables

X_RTD

ADC value of the temperature sensor, including one supply cable

X_R

ADC value of the temperature sensor

A_a, B_a

Manufacturer gain and offset calibration (R17, R18)

A_h, B_h

Manufacturer scaling

A_w, B_w:

User scaling

Y_R

Temperature sensor resistance value

Y_T

measured temperature in 1/16 °C

Y_THS

Temperature after manufacturer scaling (1/10 °C)

Y_TAS

Temperature after user scaling

Y_AUS

Process data to PLC

a) Calculation of the resistance value:

X_R = X_RTD-X_RL (1.0)

Y_R = A_a * (X_R - B_a) (1.1)

b) Curve linearization:

Y_T = a1 * Y_R2 + b1* Y_R + c1 (1.2)

Y_T = Y_R if output in Ω (1.3)

c) Neither user nor manufacturer scaling are active:

Y_AUS = Y_T (1.4)

d) Manufacturer scaling active (factory setting):

Y_THS = A_h * Y_T + B_h (1.5)

Y_AUS = Y_THS

e) User scaling active:

Y_TAS = A_w * Y_T + B_w (1.6)

Y_AUS = Y_TAS

f) Manufacturer and user scaling active: (1.7)

Y_1 = A_h * Y_T + B_h

Y_2 = A_w * Y_1 + B_w

Y_AUS = Y_2
