Programming using ladder diagram

A vending machine delivers $3$ different items each one cost $4$ AED, the machine is controlled by LOGO! Controller as follows:

User inserts coins one by one, coin sensor detects each coin and triggers a counter.

If enough coins are inserted user can order any of the three items.

Once the user makes an order a servo motor rotates to drop the desired item.

An optical sensor detects the dropped item and stops the running servo motor.

One item only can be ordered at a time.

User can cancel the process before he orders and gets back his money.

If order is canceled, machine drops out the coins via solenoid.

Use LOGO! Soft comfort to create a ladder diagram that solves this automation problem.
