1SVC 440 795 M1100
The function block operates according to the following equation
Y(x) = Actual output value of target range
X
= Actual input value of source range
X1 = Lower value of source range
X
2
= Upper value of source range
Y
1
= Lower value of target range
Y
2
= Upper value of target range
