6.3.15 U1 codes (Customizable logic functions)
U101 to
U106
Customizable Logic (Conversion point 1 (X1, Y1), Conversion point 2 (X2, Y2),
Conversion point 3 (X3, Y3))
U101 to U106 specify the three operating points for automatically calculating coefficients
(K
A
, K
B
and K
C
) in conversion 1 (K

Input signals (e.g.,
flowrate signal) and coefficients (K
A
, K
B
and K
C
) produce target signals (e.g., target
pressure). (Linearize function)

U107 Customizable Logic (Automatic calculation of conversion coefficients)
U107 automatically calculates conversion coefficients (K
A
, K
B
and K
C
) according to the
three operating points defined by U101 to U106.
The calculation results will be saved in U92 to U97. U107 automatically reverts to "0."
