Delayed Stop
When a robot has delayed stop, xhandler marks an area around the robot as long term locked, ideally just robot’s actual position. The reason for having this specifically marked as long term locked is so that the planning software will then remove any task groups that contain bins that are unavailable, due to this lock, from the port queues and the preparation queue. If a task or taskgroup is already selected by a port then it will stay selected until either, all the tasks are picked, deleted or the port is closed.
Exceptions:
- If a taskgroup has been notified via the lookahead feature then it will NOT be removed
- Bin Interface does not do this locking
- ASPlanner does not do this locking
WMS Implementation
Locking events will be communicated to the WMS using the following Log Publisher segments:
- Cell Lock (CL): https://interface.autostoresystem.com/edit/cell-lock
- Lift Cell Lock (LCL)https://interface.autostoresystem.com/edit/lift-cell-lock
It is recommended that the WMS listens to these Segements and takes appropriate action to temporarily lock this inventory or find replacement inventory for the bins included in these events.
