OR Gate Example​


The ORI closed contact orientation performs a boolean OR operation based on the OFF status of the assigned BOOL data register.

Ladder Diagram Example​


When the closed contact, M95.3, is powered OFF OR the closed contact, M33.1 is powered OFF, the coil, Y10.2, is deenergized.



When the closed contact, M95.3, is powered ON, the coil, Y10.2, is energized.



Or when the closed contact, M33.1, is powered ON, the coil, Y10.2, is energized.



If both closed contacts, M95.3 and M33.1, are powered ON, the coil, Y10.2, is energized.
