SMG-C003 COP (Car Operation Panel): This panel is located inside the elevator car. As a COP, its primary function is to allow passengers to select their destination floor, control door opening/closing, and access emergency features. The SMG-C003 likely builds upon its predecessor with potential enhancements in design, display technology (e.g., more advanced LCDs, touch interfaces), button feel, or communication capabilities, offering a modern and user-friendly experience within the elevator cabin.
