3 Basic Instructions Explanations: ANDF instruction is used in the series connection of the contacts’ falling-edge detection. Program Example: Ladder diagram: Instruction code: Operation: LD X0 Loading in A contact of X0 X0 OUT Y1 Drive Y1 coil Explanations: The ORP instructions are used in the parallel connection of the contact’s rising-edge detection. Program Example: Ladder diagram: Instruction code: Operation: X0 LD X0 Loading in A contact of X0 X1 Y1 OUT Y1 Driving Y1 coil Explanations: The ORP instructions are used in the parallel connection of the contact’s falling-edge detection.
