Pick to Light

In a Pick to Light (PTL) flow, after WMS Cloud runs a wave and creates allocations, these are then communicated to the PTL system. The PTL will have information on each allocation, container, location and item quantities to be picked.

As a container is scanned at the start of the picking module, lights light up corresponding to the allocations in that container. As the operator pushes the light buttons to confirm picks, the PTL system sends messages. Once the container is complete, a close message is received from the PTL and the container can proceed to staging. Exception scenarios such as short picks are also covered through these APIs.

Pick to Light Flow Steps

1. Run cubed or non-cubed wave.
2. Generate Wave Pick information as an output interface file to be sent to MHE’s control system.
3. Scan LPN to start packing.
4. Pick and Pack into LPN. As the lights glow, use Pack API.
5. Send short API if picked short.
6. Send Close LPN (non-cubed or automatically packed)
7. Send Complete command if all picking for given OBLPN is complete to short all remaining picks.
