All stations of the network must be uniquely identified by means of an IP address. Every
EtherNet/IP device has addressing facilities.
O
-
O
riginator: Origin station, which is responsible for the connection to the target
station.
T
-
T
arget: Target station to which a connection is established.
O
à
T - Data direction origin station to target station.
T

O - Data direction target station to origin station

are supported from VIPA
Listen Only
and
Exclusive Owner
.
n
Listen Only
–
If a connection has an application type of
Listen Only
, it shall be dependent on
just sending application connection for its existence. For a scheduled
Listen Only
connection, the FORWARD_OPEN path shall contain a schedule segment. The
O
à
T connection shall use the heartbeat format. A target may accept multiple
listen only
connections which specify the same T
à
O path. Devices that wish to
listen to multicast data without providing configuration may use this application
type. If the last connection on which a
Listen Only
connection depends is closed
or times out, the target device shall stop sending the T
à
O data, which will result
in the
listen only
connection being timed out by the originator device.
n
Exclusive Owner
–
If a connection has an application type of
Exclusive Owner
, it shall not be
dependent on any other connection for its existence. For scheduled
Exclusive
Owner
connections, the FORWARD_OPEN path shall contain a schedule seg-
ment. O
à
T application data that controls outputs may be present. A target may
only accept one
exclusive owner
connection which specifies the same O
à
T path.
In addition, the target may accept
listen only
and
input only
connections that use
the same multicast T
à
O data. The term
connection owner
shall refer to the con-
nection originator whose O
à
T packets are being consumed by the target object.
The term
owning connection
shall refer to the connection associated with connec-
tion owner. When an
Exclusive Owner
connection timeout occurs in a target
device, the target device shall stop sending the associated T
à
O data. The T
à
O
data must not be sent even if one or more
input only
connections exist. This
requirement exists to signal the originator of the
exclusive owner
connection that
the O
à
T data is no longer being received by the target device.
One possible way to prevent an Exclusive Owner connection timeout in a
target device from stopping the T
à
O production is for the target device to
also support production of the T
à
O data as point to point for the Exclu-
sive Owner connection.
From VIPA there is an EDS (Electronic Data Sheet) files for the EtherNet/IP coupler avail-
able. There the scanner can find all the information to establish a communication connec-
tion to the EtherNet/IP coupler. This file may be found in the
