 If the input value at input s3 < 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 is returned at the output value to output d.
 If the input value at input s3 > 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.

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.

Description
The function adds an offset value to the input value at input s3. The offset values for the negative
and positive areas are entered at inputs s1 and s2. The result of the function is returned at output d
