It all starts with the article. Following a precise list, when the item is identified in the Modula and the operator picks it up, the displays connected to the order to which the item belongs light up to visually indicate to the operator the container in which it must be placed and the exact quantity of that item required for that order.
So the Put to Light system guides those who work on the order during picking and clearly manages the positions where the items must be placed for each order. The correspondence is one-to-one: a luminous display is linked only to a position or container that will be the basis of the order.
