LD Gate Invert Result Example

The INV operator inverts the result of the operation up to its point.
It uses the new result as the execution condition.
The result of this inversion will be the same as the OR Gate Inversion.

If the open contact, M14.0, is powered OFF, the INV operator inverts the result to ON.
The coil, Y56.8, is energized.

If the open contact, M14.0, is powered ON, the INV operator inverts the result to OFF.
The coil, Y56.8, is deenergized.

AND Gate Invert Result Example

The INV operator inverts the result of the operation up to its point.
It uses the new result as the execution condition.

If the open contacts, M.68.3, M15.5, and M46.7, are powered OFF, the INV operator inverts the result to ON.
The coil, Y18.9 is energized.

If the open contacts, M.68.3, M15.5, and M46.7, are powered ON, the INV operator inverts the result to OFF.
The coil, Y18.9 is energized.

OR Gate Invert Result Example

The INV operator inverts the result of the operation up to its point.
It uses the new result as the execution condition.
The result of this inversion will be the same as the LD Gate Inversion.

If both open contacts, M70.8 and M51.0, are powered OFF, the INV operator inverts the result to ON.
The coil, D105.4 is energized.

If the open contact, M70.8, is powered OFF or the open contact, M51.0, is powered ON, the INV operator inverts the result to OFF.
The coil, D105.4 is energized.

If both open contacts, M70.8 and M51.0, are powered ON, the INV operator inverts the result to OFF.
The coil, D105.4 is energized.
