Bitwise Boolean instructions
F69_WUNI
The function combines the two values at inputs s1 and s2 with the value at input s3 by bit-unit
Description
processing. The result of the function is returned at output d. The data-unite is calculated as
follows:
[d] = ([s1] AND [s3]) OR ([s2] AND (NOT[s3]))
s1

When the value at input s3 = 16#0, the value at input s2 is returned at output d.
When the value at input s3 = 16#FFFF, the value at input s1 is returned at output 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.
