13.2.2 Dest Location Full during Transfer – Double Store
13.2.2.1 The Host issues a TRANSFER command to the SC to transfer a carrier from an input port to a storage
location. When the stocker attempts to place the carrier to the storage location, it finds that the location is occupied.

the stocker crane accessible

In this scenario SOURCE is the
name of a input port position
and DEST is the ZoneName
STORAGE which is a SC selected
shelf. SOURCE is optional
since the SC knows where the
CARRIERID is located.

The Host may choose to

1. Retry the TRANSFER
· The stocker attempts to
place the carrier to the dest
location again
This is a Supplier Option to
implement this Host initiated
recovery method.

STEP COMMENTS HOST SC COMMENTS
16. If the ABORT command is issued
by the Host, an unkown carrier
is created in the SC database
at the physical location
res
p
onsible for the error. This
generates a
CarrierInstalledCom
p
leted event
for the newly created carrier.
The newly created carrier is
NOT automatically sent to the
LP of the manual output port.
The host can issue a new
TRANSFER command for the
carrier currently on the crane
as well as the recentl
y
created
unkown carrier.
17. If the operator indicates, via
the stocker console (supplier
option), that the SC should
select another shelf location,
an unknown carrier is created
in the SC database at the
physical location responsible
for the error. This
g
enerates a
CarrierInstalledCom
p
leted event
for the newly created carrier.
The newly created carrier is
NOT automatically sent to the
LP of the manual output port.
The host can issue a new
Transfer command for the
recently created unknown
carrier. The original transfer
command for the carrier on the
crane completes with success at
the other shelf location.

13.2.3 Carrier ID Errors
13.2.3.1 A carrier ID error occurred. See table below for possible Carrier ID errors and resolutions.
Table 14 Carrier ID Error Scenarios at Stocker Ports
ID Error Error Description Input Port Action Intrabay Output Port Action*
Failure ID read fails
Examples of reasons for failure are:
· Bad bar code reader
· Bad bar code label
· Obstruction of bar code
read
· Other
If IDReadFailureOption is ‘Reject’
Option 1.
1. CarrierIDRead event sent.
2. Carrier automatically sent to
LP of manual output port.
3. IDReadError event sent when
carrier arrives at LP of manual
output port.
Option 2 - manual input port only.
1. CarrierIDRead event sent.
2. Stocker automatically sends
carrier back to operator accessible
location of input port(if necessary).
3. IDReadError event sent
Person picks up carrier from
input port with the PGV.
If IDReadFailureOption is
‘HostControlled’.
1. CarrierIDread event sent.
2. CarrierWaitIn event sent with
unkown carrier ID.
3. Host issues Transfer Command.
Either of the following scenarios are
acceptable based upon the supplier’s
option when moving carrier 456.
Option 1:
1. CarrierIDRead event sent.
2. Carrier continues as if there
was no reader and all events
(CarrierWaitOut,
TransferComplete, etc) will be
sent with the ID (456) of the
carrier as if there was no reader
at the port.
3. IDReadError event sent when
carrier arrives at LP of this
output port.
Option 2:
1.
CarrierWaitOut event for 456.
2. CarrierIDRead event for
Unknown carrier.
3. TransferComplete for 456 with
ID failure error.
4. SC automatically deletes carrier
456 from database and sends
CarrierRemoveCompleted event.
5. SC automatically creates
Unknown carrier at the port and
sends event according to Carrier
State Model.
6. Carrier continues to or remains at
LP of this output port with
CarrierWaitOut for created
Unknown carrier at each position.
7. IDReadError event sent when
carrier arrives at LP of this output
port.
