Inputs
I1: Assign the unscaled value to function block input I1.
X1 and Y1: You define the first support point of the straight line at function
block inputs X1 and Y1.
X2 and Y21: The second pair of values at function block inputs X2 and Y2
determines the second support point of the straight line.
You can assign the following operands to function block inputs I1, X1, Y1,
X2 and Y2:
•
Constant
•
Markers MD, MW, MB
•
Analog inputs IA01 to IA04:
•
IA01: Terminal I7
•
IA02: Terminal I8
•
IA03: Terminal I11
•
IA04: Terminal I12
•
Analog output QA01
•
Output
…
QV> of a different function block
Output
The output QV supplies the scaled value as an integer.
You can assign the following operands:
•
Markers MD, MW, MB
•
Analog output QA01

The scaling function block must be enabled via coil LS..EN = 1
in order for it to work. If the coil LS..EN is not active, the entire
function block is deactivated and reset. The output value is set
to zero.
