Silo simulation exercise

A excercise to create a ladder logic diagram
Exercise #1 -- Continuous Operation
Completely design and de-bug a ladder control circuit which will automatically position and fill the boxes which are continuously sequenced along the conveyor. Ensure that the following details are also met:
The sequence can be stopped and re-started at any time using the panel mounted Stop and Start switches.
The RUN light will remain energized as long as the system is operating automatically.
The RUN light, Conveyor Motor and Solenoid will de-energize whenever the system is halted via the STOP switch.
The FILL light will be energized while the box is filling.
The FULL light will energize when the box is full and will remain that way until the box has moved clear of the prox-sensor.
