Calculation of process data
The terminal continuously takes measured values and stores the raw values of its A/D converter in register
R0 [} 34] (RAM ). The calculation of the correction with the calibration values takes place after each
sampling of the analog signal. This is followed by manufacturer and user scaling:
The process data that are transferred to the Bus Coupler are calculated using the following equations:
Y_a = (B_a + X_adc) * A_a
Y_aus = Y_a
Y_1 = B_h + A_h * Y_a
Y_aus = Y_1
Y_2 = B_w + A_w * Y_a
Y_aus = Y_2
Y_1 = B_h + A_h * Y_a
Y_2 = B_w + A_w * Y_1
Y_aus = Y_2

The equations of the straight line are enabled via register R32 [} 37].
