Bitwise Boolean instructions
F66_WOR
Executes OR operation of each bit in 16-bit equivalent constant or 16-bit data specified by s1 and
Description
s2 if the trigger EN is in the ON-state. The OR operation result is stored in the 16-bit area specified
by d. When 16-bit equivalent constant is specified by s1 or s2, the OR operation is performed
internally converting it to 16-bit binary expression. You can use this instruction to turn ON certain
bits of the 16-bit data.

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.
