Floating point data zone control
 If the input value at input s3 < 0.0, the negative offset value at input s1 is added
to the input value at s3, and the result is stored as the output value at d.
 If the input value at input s3 = 0.0, 0.0 is returned as the output value to output d.
 If the input value at input s3 > 0.0, the positive offset value at input s2 is added to
the input value at s3, and the result is stored as the output value at d.

Output value d
Positive bias
value s2
Input value s3
Negative bias value s1
This instruction also exists as a P instruction (for FP2/2SH, FP3/5, FP10/10SH PLC types), which
is only executed at the rising edge of the EN trigger. Select [Insert P instruction] from the
"Instructions" pane if you require a P instruction. To facilitate reuse, the instruction then appears
under "Recently used" in the pop-up menu. Press <Ctrl>+<Shift>+<v> within the programming
area to open the list of recently used elements.

Variable Data type Function
s1 REAL area where negative bias value is stored or negative bias
value data
s2 REAL area where positive bias value is stored or positive bias value
data
s3 REAL area where input value is stored or input value data
d REAL area where output value is stored
Description
The function adds an offset value to the input value at input s3. The offset value for the negative
and positive area are entered at inputs s1 and s2. The result of the function is returned at output d
as follows:
