Good day,

I got a job, but I can't figure out how to make the movement of the elevator on which floor it is located. And I also can't handle the SET and P0 functions as the exact number of outputs must be observed.

Assignment:

The elevator will be controlled by 4 command inputs (P0, P1, P2 and P3), the time of the elevator movement will be modeled by a suitable delay.

Work output:

The elevator will also be equipped with inputs with signaling of the door status, reaching the stop (reaching P0). The outputs will signal the running of the motor (intermittent flashing) and the reaching of individual floors (P0 is not lit and the others light up when they are reached).

- 4 inputs P0 to P3 for floor selection,

- 1 DOOR input to indicate the status of the door

- 1 SET input for indication of travel to P0 (set sets elevator car to P0)

3 outputs P1, P2 and P3 to indicate the floor reached and

- 1 RUN output for motor control

Thank you for any advice
