00 0000 Normal status code:
The connection has been
opened and the tag data link is
communicating normally.
--- --- ---
01 0100 Error code returned from target:
Attempted to open multiple con-
nections at the same connec-
tion.
This error does
not occur.
Depends on the tar-
get’s specifications.
(Contact the target
device’s manufac-
turer for details on
preventing the error
from occurring in the
future.)
Depends on the orig-
inator’s specifica-
tions.
(Contact the origina-
tor device’s manufac-
turer for details on
preventing the error
from occurring in the
future.)
01 0103 Error code returned from target:
Attempted to open a connection
with an unsupported transport
class.
This error does
not occur.
Confirm that the tar-
get supports Class
1.
Confirm that the
originator supports
Class 1.
01 0106 Duplicate consumers:
Attempted to open multiple con-
nections for single-consumer
data.
If the tag data link
is stopped or
started, this error
may occur accord-
ing to the timing,
but the system will
recover automati-
cally.
Depends on the tar-
get’s specifications.
(Contact the target
device’s manufac-
turer.)
If the tag data link is
stopped or started,
this error may occur
according to the tim-
ing, but the system
will recover automat-
ically.
01 0107 Error code returned from target:
Attempted to close a connec-
tion, but that connection was
already closed.
This error does
not occur.
This error does not
occur.
This is not an error
because the connec-
tion is already
closed.
01 0108 Error code returned from target:
Attempted to open a connection
with an unsupported connection
type.
This error does
not occur.
Check which con-
nection types can be
used by the target.
(Contact the manu-
facturer.)
Only multicast and
point-to-point can be
set.
Check which con-
nection types can be
used by the origina-
tor.
(An error will occur if
a connection other
than multicast or
point-to-point is set.)
