Connecting to the Network
Section 3-3
There are three ways to connect the Network Configurator to the network.
a.
Connection via a USB port (connection to an NE1A-series Controller)
b.
Connection via a DeviceNet Interface Card
c.
Connection via Ethernet (NE1A-EDR01: Network Configurator version
2.0
@
or higher, NE1A-SCPU01-EIP or NE1A-SCPU02-EIP: Network
Configurator version 2.2
@
or higher)
With Network Configurator version 1.6
@
or earlier, operations (e.g., down-
loading and uploading) can be performed only for networks that have devices
connected. In the figure above, if a connection is made at network 1, only
devices on DeviceNet_1 can be accessed, and if connection is made at net-
work 2, only devices on DeviceNet_2 can be accessed.
When using Network Configurator version 2.0
@
or higher with a network that
contains the NE1A-EDR01, CPU Units with unit version 2.0, and CPU Units
that support EtherNet/IP (see note 2), uploading, downloading, and other
online operations can be performed for networks other than the network to
which the connected device belongs. If a connection is made to the NE1A-
SCPU01 Controller (pre-version 1.0) in network 1, operations can be per-
formed only for the DeviceNet_1 network.
Note
(1) For CPU Units with unit version 1.0 or earlier, uploading and downloading
can be performed only for devices that are connected to the network to
which the CPU Unit belongs.
(2) CPU Units (with EtherNet/IP) support the Network Configurator of version
2.2
@
or higher.
When the Network Configurator is connected to the network, a blue icon will
be displayed on the tab of a destination network, and a green icon will be dis-
played on the tab of an operable network, as in the following figure.
The tab may remain grey after a network has been set to online. This indi-
cates that the network is inoperable at the present online destination. The
connection destination must be changed to operate the network. Change the
connection destination using the procedure described in
3-3-5 Changing a
Connection Destination
.
3-3-5
Changing a Connected Network
This section describes how to change a connection destination.
Note
This function is enabled only when connection is made to the NE1A-EDR01
via Ethernet, connection is made to the NE1A-SCPU02 (unit version 2.0) via
DeviceNet_1
EtherNet_1
DeviceNet_2
