F131_BTR
Turns OFF the bit specified by the bit position at n of the 16-bit data specified by d if the trigger EN
Description
is in the ON-state. Bits other than the bit specified do not change. The range of n is 0 to 15.
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.
