Elevator with the following simplifications:
- There is no weight sensor and no Stop button in the cars
- All call buttons are constantly active. The call buttons in the car have higher priority.
3 sensors/buttons for calling the elevator on the relevant floor (0, 1, 2),
3 sensors/buttons in the elevator for selecting the destination floor (0, 1, 2),
3 sensors for detection of the floor on which the elevator is located,
3 sensors for detection of whether the doors are closed on the floors.
1 actuator for moving the elevator upwards and 1 actuator for moving the elevator downwards.
3 actuators for opening the door on the relevant floor (0, 1, 2).
