Part III FP Instructions
F132_BTI
16-bit data bit invert
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
d ANY16 16-bit area
n INT specify bit position to be inverted
For Relay T/C Register Constant
d - WY WR WL SV EV DT LD FL -
n WX WY WR WL SV EV DT LD FL dec. or hex.
Description
Inverts [1 (ON) 0 (OFF) or 0 (OFF) 1 (ON)] the bit at bit position n in the 16-bit data area
specified by d if the trigger EN is in the ON-state. Bits other than the bit specified do not change.
The range of n is 0 to 15.
