2. Terms and Definitions
Term Explanation and Definition
Node Controllers and devices are connected to the EtherNet/IP network via
the EtherNet/IP ports. The EtherNet/IP recognizes each EtherNet/IP port
connected to the network as one node.
When a device with two EtherNet/IP ports is connected to the
EtherNet/IP network, the EtherNet/IP recognizes this device as two
nodes.
The EtherNet/IP achieves the communications between controllers or
the communications between controllers and devices by exchanging
data between these nodes connected to the network.
Tag A minimum unit of the data that is exchanged on the EtherNet/IP network
is called a tag. The tag is defined as a network variable or as a physical
address, and it is allocated to the memory area of each device.
Tag Set In the EtherNet/IP network, a data unit that consists of two or more tags
can be exchanged. The data unit consisting of two or more tags for the
data exchange is called a tag set. Up to eight tags can be configured per
tag set for OMRON controllers.
Tag data link In the EtherNet/IP, the tag and tag set can be exchanged cyclically
between nodes without using the user program. This standard feature on
the EtherNet/IP is called a tag data link.
Connection A connection is used to exchange data as a unit within which data
concurrency is maintained. The connection consists of tags or tag sets.
Creating the concurrent tag data link between the specified nodes is
called a "connection establishment". When the connection is
established, the tags or tag sets that configure the connection are
exchanged between the specified nodes concurrently.
Specifying the tag set name (tag name) and specifying the instance
number of Assembly Object are given as methods to specify the
connection. In Sysmac Studio, the connection is set by specifying the
instance number.
Connection type There are two kinds of connection types for the tag data link connection,
one is a multi-cast connection and the other is a unicast (point-to-point)
connection. The multi-cast connection sends an output tag set in one
packet to multiple nodes. The unicast connection separately sends one
output tag set to each node. Therefore, multi-cast connections can
decrease the communications load if one output tag set is sent to
multiple nodes.
5
Term Explanation and Definition
Originator and
Target
To perform tag data links, one node requests the opening of a
communications line called a "connection".
The node that requests to open the connection is called an "originator",
and the node that receives the request is called a "target".
Each data for communications is called an ''originator variable'' and a
''target variable''.
Tag data link
parameter
The tag data link parameter is the setting data to perform the tag data
link. It includes the data to set tags, tag sets, and connections.
EDS file A file that describes the number of I/O points for the EtherNet/IP device
and the parameters that can be set via EtherNet/IP.

7. EtherNet/IP Connection Procedure
This section describes the procedure for connecting NX-I/O Series to the PLC via EtherNet/IP.
7.1. Selecting NX-I/O and Designing the Power Supply System
Selecting NX-I/O:
As a general guideline modules NOT supported are as follows:
Timestamp digital IO modules
Serial Communications Modules
Pulse Output Modules
Note: For information on a specific card compatibility with the Coupler, please see NX Data
Reference Manual W525-E1-06 Appendix A-3 Compatibility of Couplers.
Designing the Power Supply System:
The total power consumption from the NX Unit Power Supply must not exceed the NX Unit
Power Supply capacity of the Unit that supplies the NX Unit power.
Use the following procedure to design the NX Unit Power Supply.
1 Calculate the total power consumption from the NX Unit Power Supply that is required
by the NX Units that are connected to the EtherNet/IP Coupler Unit.
2 If the total power consumption from the NX Unit Power Supply exceeds the NX Unit
Power Supply capacity of the EtherNet/IP Coupler Unit, add an additional NX Unit Power
Supply Unit to the right of an NX Unit before the capacity is exceeded.
3 Calculate the total power consumption from the NX Unit Power Supply that is required
by the NX Units that are connected after the additional NX Unit Power Supply Unit.
If the total power consumption of those NX Units exceeds the NX Unit Power Supply
capacity of the Additional NX Unit Power Supply Unit, add another Additional NX Unit
Power Supply Unit to the right of an NX Unit before the capacity is exceeded.
4 Repeat Step 3 until the design conditions for the NX Unit Power Supply are met.

7.2. Setting up the Coupler
Make sure that the Coupler has no previous file configured onto it. If it has a previous
configuration, Sysmac Studio is needed to clear all the memory in the coupler. During power
up and initialization, the EtherNet/IP coupler automatically detects connected NX Units and
applies a default configuration. If the order or type of any of the slices is changed, then the
Coupler will need to be cleared.
Previous Configuration File
NX Unit operation settings are stored in the EtherNet/IP Coupler Unit. If an EtherNet/IP Coupler Unit has been previously configured, the memory needs to be cleared using the Clear All Memory option in Sysmac Studio before attempting this configuration procedure. Otherwise, stored settings for NX Units that were previously mounted may be automatically transferred to mounted NX Units.
7.2.1. Setting IP Address with Switch Settings
The following switches are used to set the node address. The setting range is from 001 to 254.
If these switches are used, the node address that is set on the switches will be valid. (The
factory setting is 000).
Switch Node Address Range Node Address Setting
DIP switch pin 4 ON
DIP switch pin 4 OFF
192.168.1.� or
192.168.250.�
Preset
Top rotary switch
Bottom rotary switch
0-F
0-F
1 to 254 (setting 01 to FE)
Note: For more information on setting the IP address with switch setting, see the NX-EIC202
EtherNet Coupler User Manual W536-E1-02
Precautions for Correct Use
• The IP address corresponding to the switches is read only once when the Unit Power
Supply is turned ON or the EtherNet/IP Coupler Unit is restarted. If the node address is
changed after the Unit Power Supply is turned ON or after the EtherNet/IP Coupler Unit is
restarted, the new node address will not be used until the next time that power is turned ON
or the EtherNet/ IP Coupler Unit is restarted.
• An error will occur if the same node address is set for more than one Unit.
• An error will occur if the same IP address is set for more than one Unit.
• An error will occur if the node address is not within the setting range.
13
7.3. Setting up the PLC
Set up the PLC.
7.3.1. Hardware Settings
Set the hardware switches on the Ethernet/IP Unit and wire the network.
Precautions for Correct Use
Make sure that the Power Supply is OFF when you perform the setting up.
1. 1 Make sure that the Power
Supply to the PLC and the
Switching hub is OFF.
*If the Power Supply is turned
ON, settings may not be
applicable as described in the
following procedure.
2. 2 Check the positions of the
hardware switches on the front
of the EtherNet/IP Unit by
referring to the right figure.
3. 3 Set the Unit number setting
switch to 0.
The unit number is used to identify individual CPU Bus Units when
more than one CPU Bus Unit is mounted to the same PLC. Use a
small screwdriver to make the setting, taking care not to damage the
rotary switch. The unit number is factory-set to 0.
14
4. 4 Set the Node address setting
switches to the following default
settings.
NODE No.x161: 0
NODE No.x160: 1
*Set the IP address to
192.168.250.01.xxx
*By default, the first to third
octets of the local IP address
are fixed to 192.168.250. The
fourth octet is the values that are
set with the Node address
setting switches.
When there are multiple EtherNet/IP Units connected to the Ethernet
network, the EtherNet/IP Units are identified by node addresses. Use
the node address switches to set the node address between 01 and
FE hexadecimal (1 to 254 decimal).Do not set a number that has
already been set for another node on the same network
The left switch sets the sixteens digit (most significant digit) and the
right switch sets the ones digit (least significant digit).The node
address is factory-set to 01.

perform unexpected operation. Take sufficient safety precautions and proceed
to this section. If you cannot confirm safety, do not proceed to this section after
completing until Section 7.4.1. If you proceed to this section, make sure to
complete all the steps and place the Target Device in the safe state.
If you wire the I/O in the state that the Power Supply to the devices is turned ON,
doing so may cause damage to the devices. Always read and heed the
information provided in all safety precautions of manuals for each device to be
wired.

8. Appendix
8.1. Assigning Network Variables
8.1.1. Basic I/O Mapping
The numbers used to identify NX Units in a Slave Terminal are called Unit Numbers. These
numbers are allocated automatically from left to right starting with 1 when the power is turned
ON. It is not necessary for the user to set these numbers. The EtherNet/IP Coupler Unit will
have a unit number of 0.
The type and order in which NX Units are mounted will determine the I/O allocation and will
also affect the Network Variable address assignments in the PLC. Refer to
NX-EIC202_EtherNetIP_Coupler_UserMan_en_201504_W536-E1-02,9-5-5 Creating Tags
and Tag Sets on page 9-41 for more information about importing/exporting Network variables.
The figure below shows this mapping.

I/O Mapping Example
I/O data is mapped to the EtherNet/IP Coupler Unit’s I/O data blocks in the same order the NX
Units are connected to the EtherNet/IP Coupler Unit, regardless of the NX Units’ models. The
example below shows the I/O data mapping to the Input / Output blocks.
Note: For more information see NX-series EtherNet/IP Coupler Unit User’s Manual W536
