Internal Port Queues

Overview

AutoStore creates internal Port queues when using the Task Interface.

• These Port queues are normally not visible (see Viewing the Internal Queue below for exceptions).
• If a Port is closed, task groups in its queue may be reflowed into another Port’s queue.
• The queue is dynamic and continuously changes based on the system’s current state.

For example, the system may reorder task groups to maximize throughput or to allow task groups with an earlier requested time to be selected more quickly.

Viewing The Internal Queue

• Use the configureport method together with the getnexttaskgroups method (the configureport method can also be used within the Console).
• The getnexttaskgroups method returns a list of planned task groups for a specific Port.
• A PTG segment will be sent by the Log Publisher, including the list of planned task groups.

⚠️

The queue is locked for the number of Bins configured. The getnexttaskgroups method only returns the list of planned task groups; it does not lock the queue. The queue is locked as soon as the Port is configured using configureport. This setting can be cleared by setting the configuration value to 0.

Content Code Bin Selection

• When requesting Bins via content codes, AutoStore will never select Bins that are already in any Port queue, whether internal or set by the WMS.
• This rule applies to both internal queues and queues configured by the WMS.
