32.6.5.1 Explanation of the Invert (INV) Instruction

When an INV instruction is executed, reverse processing is performed. If the state is OFF before the INV instruction is executed, the state will be inverted to ON.

If the state is ON before the INV instruction is executed, the state will change to OFF as a result of the INV instruction.

Program Example

When the operand of the normally open instruction is ON, the INV instruction will execute and the OUT coil turns OFF.

When the operand of the normally open instruction is OFF, the INV instruction will execute and the OUT coil turns ON.
