Every Transport of a Shelf access equipment returns a TQUI with the following states
|
|
|
|
- 01: Order complete - box was transported correctly
|
|
- 02: Order aborted - no transport happened
|
|
- 03: No crate - there was no box in the source of the Transport may cause dummybox transport
|
|
- 04: Destination occupied - there is no place for the box in destination
|
|
- 05: Wrong box loaded - generate alternate Transport
|
|
- 11: Order complete Dummy - detected dummy and return it to depot
