Cargo Elevator System Using XG5000 PLC Programming

The XG5000 PLC program implements a three‑floor cargo elevator that moves one floor at a time using up and down push‑buttons. Limit‑switch sensors on each floor provide position feedback, while a latched SYSTEM_ON memory bit keeps the controller active after the start button is pressed. The ladder logic uses SET and RESET coils to energize outputs for each travel direction, ensuring the motor stops when the target floor’s limit switch is triggered. Dedicated rungs handle start/stop, floor‑1 → 2, floor‑2 ↔ 3, and floor‑3 → 2 operations.
