Introduction
EtherNet/IP Features
EtherNet/IP is an industrial multi-vendor network that uses Ethernet.
The EtherNet/IP specifications are open standards managed by the ODVA (Open DeviceNet Vendor
Association), just like DeviceNet.
EtherNet/IP is not just a network between Controllers. It is also used as a field network. Because
EtherNet/IP uses standard Ethernet technology, various general-purpose Ethernet devices can be
used in the network.
1-1-2
High-speed, High-capacity Data Exchange through Tag Data Links
The EtherNet/IP protocol supports implicit communications, which allows cyclic communications
(called tag data links in this manual) with EtherNet/IP devices.
Tag Data Link (Cyclic Communications) Cycle Time
Tag data links (cyclic communications) operate at the cyclic period specified for each application,
regardless of the number of nodes. Data is exchanged over the network at the refresh cycle set for
each connection, so the communications refresh cycle will not increase even if the number of nodes is increased, i.e., the concurrency of the connection's data is maintained.
Because the refresh cycle can be set for each connection, each application can communicate at its
ideal refresh cycle. For example, interprocess interlocks can be transferred at high speed, while the
production commands and the status monitor information are transferred at low speed.
Features of Built-in EtherNet/IP Port on NJ/NX-series CPU Units
Tag Data Links
Cyclic communications between Controllers or between a Controller and other devices are possible
on an EtherNet/IP network.
High-speed data exchange can be performed through tag data links.

1 Introduction
CIP Message Communications
You can send CIP commands to devices on the EtherNet/IP network when required by executing
CIP communications instructions in a program.
As a result, it is possible to send and receive data with the devices on the EtherNet/IP network.
BOOTP Client
If the built-in EtherNet/IP port on an NJ/NX-series CPU Unit is set in the BOOTP settings, the
BOOTP client operates when the Controller power is turned ON, and the IP address is obtained
from the BOOTP server.
It is possible to set all of the IP addresses of multiple built-in EtherNet/IP ports at the same time.
1-1 Introduction

1-1-2 Features of Built-in EtherNet/IP Port on NJ/NX-series CPU Units
FTP Server for File T
An FTP server is built into the Controller. You can use it to read and write data within the Controller
as files from workstations and computers with FTP clients.
The FTP server enables the transfer of large amounts of data from a client without any additional
ladder programming.
FTP Client for File Transfers to and from Host Computers
An FTP client is built into the Controller, so you can read and write files on workstations and computers that have an FTP server from the Controller.
You can use the FTP client communications instructions to transfer one or more files between the
Controller and an FTP server.
NTP Client for Automatic Controller Clock Adjustment
The clocks built into Controllers connected to Ethernet can be automatically adjusted to the time of
the clock in the NTP server. If all of the clocks in the system are automatically adjusted to the same
time, time stamps can be used to analyze production histories.
*1. A separate NTP server is necessary to automatically adjust the Controller clocks.
Socket Services
Socket services can be used to send and receive data between general-purpose applications and
Controllers.
Through the communications services with sockets, you can send and receive data to and from remote nodes, i.e., between the host computer and Controllers or between Controllers.
You can execute socket communications instructions in order in a program to execute communications processes with the socket services.
There are two socket services, the UDP socket service and TCP socket service.
ransfers to and from Host Computers
DNS Client for Specifying Host Names
When you specify an NTP server, SNMP manager, or the destination of socket instructions or CIP
communications instructions, you can use the host name, as well as its IP address (DNS client or
hosts settings).
This will help identify the IP address automatically even after the IP addresses of relevant servers
are changed due to system revisions.
*1. A separate DNS server is necessary when you use host names with the DNS client.
*2. The DNS server is specified directly using its IP address.

Network Management with an SNMP Manager
The SNMP agent passes internal status information from the built-in EtherNet/IP port to network
management software that uses an SNMP manager.

Complete Troubleshooting Functions
A variety of functions are provided to quickly identify and handle errors.
• Self-diagnosis at startup
• Event log that records the time of occurrence and other error details
Two EtherNet/IP Communications Ports as a Standard Feature, Equipped
with IP Routing Function (Only with the NX701 and NX102 CPU Units)
These CPU Units are equipped with two EtherNet/IP ports for EtherNet/IP communications as
standard.
This feature allows you to separate the information network from the control network. In addition,
the built-in EtherNet/IP ports support the IP routing function to send IP packets to devices on other
IP network segments.

CIP Safety on EtherNet/IP Compatible
Combined with the NX-SL5£££
Safety on EtherNet/IP communications in networks between Controllers and field networks. Safety
communications by CIP Safety is enabled with devices that support CIP Safety on EtherNet/IP and
other Safety CPU Units.
Additional Information
CIP (Common Industrial Protocol)
CIP is a shared industrial protocol for the OSI application layer. The CIP is used in networks
such as EtherNet/IP
Data can be routed easily between networks that are based on the CIP. You can therefore easily configure a transparent network from the field device level to the host level.
The CIP has the following advantages.
• Destination nodes are specified by a relative path, without fixed routing tables.
• The CIP uses the producer/consumer model. Nodes in the network are arranged on the same
level and it is possible to communicate with required devices whenever it is necessary.
The consumer node will receive data sent from a producer node when the connection ID in
the packet indicates that the node requires the data. Because the producer can send the
same data with the same characteristics in a multicast format, the time required for the transfer is fixed and not dependent on the number of consumer nodes. (Either multicast or unicast
can be selected.)

1 Introduction
CIP Message Communications
User-specified CIP commands can be sent to devices on the EtherNet/IP network.
CIP commands, such as those for reading and writing data, can be sent and their responses received
by executing the CIP communications instructions from the user program in the NJ/NX-series CPU
Unit.
By specifying a route path, you can send CIP messages (CIP commands and responses) to a device
on another CIP-based network segment via a built-in EtherNet/IP port or the EtherNet/IP Unit (CIP
routing function for message communications).
The maximum number of levels of CIP routing via the ports is eight for any combination of CS, CJ, NJ,
and NX-series CPU Units. Note that the number of levels of IP routing using an L3 Ethernet switch is
not counted in the number of levels of CIP routing via the ports.
• NX701 CPU Unit and NX102 CPU Unit
Because there are two built-in EtherNet/IP ports, CIP routing is possible by the CPU Unit alone.
1-20
• NJ-series CPU Unit
By combining the built-in EtherNet/IP port and an EtherNet/IP Unit, CIP routing can be performed.

Additional Information
In CIP routing, a node (Unit) that routes information subtracts the equivalent of one hop from
the timeout, deletes its own address from the route information, and relays the information to
the next node (Unit).
When a timeout is specified, the timeout for the actual request service processing is set in the
last hop.
In the case of relay hops, the timeout for the relay route must be added to the timeout for the
request.
OMRON products that support CIP subtract 5 seconds per hop.

Version Information
For NJ-series CPU Unit, you can use the EtherNet/IP Unit with the CPU unit version 1.01 or
later and the Sysmac Studio version 1.02 or higher.
IP Routing
The built-in EtherNet/IP on the NX701 CPU Unit and NX102 CPU Unit have the IP routing function.
The IP routing function sends IP packets to other network segments based on the routing information
set in the IP router table.
o communicate with devices on other network segments, you must set the IP router table and default
T
gateway settings for the CPU Unit and each device on the network appropriately for your network configuration.
Precautions for Correct Use
• You cannot create tag data links between multiple CPU Units using IP routing on the NX701
CPU Unit and NX102 CPU Unit.
• The IP routing function can only be used with the NX701 CPU Units and NX102 CPU Units.
IP routing cannot be used with a combination of a built-in EtherNet/IP port on an NJ-series
CPU Unit and an EtherNet/IP Unit.

Port Forward - IP Forward
This function divides the network for the built-in EtherNet/IP ports 1 and 2. When you divide the
network, set IP Forward to Do not use. When it is set to Do not use, any other IP packets than
those addressed to the Controller are discarded. Refer to 5-1 TCP/IP Settings

Additional Information
CIP routing is not be affected by the IP Forward setting.
Packet Filter
IP packets are filtered in the receive processing at the built-in EtherNet/IP ports. When the Packet Filter setting is enabled, it will allow you to connect the Sysmac Studio only from a computer with the IP
address registered, and restrict any other connection from those with unregistered IP addresses. This
function can be used only for the NX102 CPU Unit.

Ethernet Switch Types
Unmanaged Layer 2 (L2) Ethernet Switches
These Ethernet switches use the Ethernet MAC address to switch ports. Ordinary Ethernet
switches have this function. Ethernet switch functions and settings cannot be changed.
Managed Layer 2 (L2) Ethernet Switches
These Ethernet switches use the Ethernet MAC address to switch ports. Ethernet switch functions
and settings can be changed with special software tools for Ethernet switches running on a network
node. You can also collect analytical data. These Ethernet switches provide more-advanced functions than unmanaged layer 2 Ethernet switches.
Ethernet Switch Functions
This section describes the Ethernet switch functions that are important for an EtherNet/IP network. For
a built-in EtherNet/IP port, consider whether the Ethernet switch supports these functions when you
select the Ethernet switch.
• Multicast filtering
QoS (Quality of Service) for TCP/UDP port numbers (L4)
•
2
2-1-2 Ethernet Switch Types
Multicast Filtering
Multicast filtering transfers multicast packets to the specific nodes only. This function is implemented in the Ethernet switch as IGMP snooping or GMRP.
“Specific nodes” are nodes equipped with an IGMP client, and have made transfer requests to the
Ethernet switch. (OMRON built-in EtherNet/IP ports are equipped with an IGMP client.) When the
Ethernet switch does not use multicast filtering, multicast packets are sent to all nodes, just like
broadcast packets, which increases the traffic in the network.
Settings must be made in the Ethernet switch to enable this function. There must be enough multicast filters for the network.
QoS (Quality of Service) Function for TCP/UDP Port Numbers (L4)
This function controls the priority of packet transmissions so that packets can be sent with higher
priority to a specific IP address or TCP (UDP) port. The TCP and UDP protocols are called transport layer protocols, leading to the name L4 (layer 4) QoS function.
NJ/NX-series CPU Unit Built-in EtherNet/IP Port User’s Manual (W506)

2 Installing Ethernet Networks
When tag data links and message communications are executed on the same network, tag data
links can be sent at higher priority to prevent problems such as transmission delays due to message communications traffic and packet losses due to buf
Settings must be made in the Ethernet switch to enable this function and give higher priority to tag
data link packets.
These functions are supported by Ethernet switches as described in the table below.

If the Network Configurator is used to set the connection type in the connection settings to a
Multicast Connection, multicast packets are used. If the connection type is set to a Point to
Point Connection, multicast packets are not used.
Precautions for Ethernet Switch Selection
The functions supported by the Ethernet switch may affect tag data link transmission delays and the
settings in the Controller configurations and setup.
In addition, if the Ethernet switch supports advanced functions, special settings are required for the
functions.
When you select an Ethernet switch, it is necessary to consider what kind of data transmission and

Executing Tag Data Links Only
We recommend that you use an L2 Ethernet switch without multicast filtering or an L2 Ethernet
switch with multicast filtering.
An L2 Ethernet switch with multicast filtering prevents increased traffic due to unnecessary multicast packets, so the tag data links can operate at higher speed.
If either of the following conditions exists, there is no dif

Executing Tag Data Links and Message Communications
We recommend an L2 Ethernet switch with multicast filtering and L4 QoS.
If you set tag data links for higher-priority transmission, it is possible to prevent problems such as

Selecting the Ethernet Switch Based on the Ethernet Switch's Supported Functions
L2 Ethernet Switch without Multicast Filtering
We recommend this kind of Ethernet switch when only tag data links are executed and any of the
following conditions is met.
• The tag data links are set to share the same data with all nodes in the network. (Multicast packets are transferred to all nodes in the network, just like broadcast transmission.)
•
The tag data link settings are all one-to-one (unicast) and multicast packets cannot be used.
• There is little traffic in the tag data links.
No special settings are required for an L2 Ethernet switch without multicast filtering.
L2 Ethernet Switch with Multicast Filtering
We recommend this kind of Ethernet switch when only tag data links are executed and the following condition is met.
• There are many 1:N links (where N represents some number of nodes in the network) in the tag
data link settings, i.e., there are many multicast packets used, or there is heavy traffic in the tag
data links.
Specific settings are required for an L2 Ethernet switch with multicast filtering. There must be
enough multicast filters for the network.
2-1-4 Precautions for Ethernet Switch Selection
L3 Ethernet Switch with Multicast Filtering and L4 QoS Functions
We recommend this kind of Ethernet switch when both tag data links and message communications are executed.
If you set tag data links for higher-priority transmission, you can prevent problems such as transmission delays due to message communications traffic and packet losses due to buffer overflow.
When multicast filtering and L4 QoS are used, settings must be made accordingly on the Ethernet
switch. There must be enough multicast filters for the network.

2 Installing Ethernet Networks
Selecting the Ethernet Switch Based on the Network Communication Speed
Executing Tag Data Links at a Baud Rate Over 100 Mbps
If you use data tag links with the following conditions, use an Ethernet switch with multicast filtering
or an Ethernet switch that supports a baud rate of 1,000 Mbps.
• Multicast
•
Baud rate over 100 Mbps
If there is an Ethernet device on the same network that communicates at a speed of 100 Mbps or
less, the device may affect tag data link communications and cause tag data links to be broken,
even if the device is not related to tag data link communications.
Precautions for Correct Use
• Ask the Ethernet switch manufacturer for setting procedures for the Ethernet switch.
• Install the Ethernet switch based on its environmental resistance specifications so that the
environmental resistance specifications are fully met. Ask the Ethernet switch manufacturer
for information on the environmental resistance of the Ethernet switch.

Network Installation
Basic Installation Precautions
• Take the greatest care when you install the Ethernet System. Be sure to follow ISO 8802-3 specifications. Be sure you understand them before attempting to install an Ethernet System.
• Unless you are already experienced in installation of communications systems, we strongly recommend that you employ a professional to install your system.
• Do not install Ethernet equipment near sources of noise.
If a noisy environment is unavoidable, take adequate measures against noise interference, such as
installation of network components in metal cases or the use of optical cable in the system.
• When using a shielded cable with the shields on both ends of the cable connected to connector
hoods, ground loops induced by improper grounding methods may decrease noise immunity and
cause device damage. To prevent ground loops caused by differences in potential between device
grounding points, the reference potential between the devices must be stabilized. Design grounding
appropriately so that noise current does not flow to ground lines between the devices. For grounding
methods, refer to the NJ-series CPU Unit Hardware User's Manual (Cat. No. W500), NX-series CPU
Unit Hardware User’s Manual (Cat. No. W535), NX-series NX102 CPU Unit Hardware User’s
Manual (Cat. No. W593), or NX-series NX1P2 CPU Unit Hardware User's Manual (Cat. No. W578).
• To obtain information on installing EtherNet/IP cable, contact ODVA.
ODVA web site: http://www.odva.org
• When you install an EtherNet/IP network that combines an information network with the control system, and the communications load may be heavy due to tag data links, we recommend that you set
up a network where the load does not affect communications. For example, install the tag data links
in a segment that is separate from the information network.

Regardless of which baud rate is used, check with the Ethernet switch manufacturers for information about installing the network between Ethernet switches, and in particular whether or not it is
necessary to connect the cable shields to the connector hoods.
Other Precautions When Laying the Twisted-pair Cable
• Firmly insert the connector until it locks into place when you connect the cable to the Ethernet switch
and the built-in EtherNet/IP port.
• Do not install the twisted-pair cable together with high-voltage lines.
•
Do not install the twisted-pair cable near devices that generate noise.
• Do not install the twisted-pair cable in locations subject to high temperatures or high humidity.
• Do not install the twisted-pair cable in locations subject to excessive dirt, dust, oil mist or other contaminants.
Recommended Clamp Core and Attachment Method
When you use a NX-series CPU Unit and connect the cable shield only with the connector hood of the
Ethernet switch, you need to attach a clamp core to the EtherNet/IP port of the CPU unit.

Precautions When Installing and Connecting Ethernet Switches
Precautions When Installing Ethernet Switches
• Do not ground the Ethernet switch in the same location as a drive-system component, such as an
inverter.
•
Always use a dedicated power supply for the Ethernet switch. Do not use the same power supply for
other equipment, such as an I/O power supply, motor power supply, or control power supply.
• Before installation, check the Ethernet switch's environmental resistance specifications, and use an
Ethernet switch that is appropriate for the ambient conditions. Contact the Ethernet switch manufacturer for details on Ethernet switch's environmental resistance specifications.
Ethernet Switch Connection Methods
• Connect Ethernet switches with twisted-pair cables, as follows: Connect an MDI port to an MDI-X
port with a straight cable. Connect two MDI ports or two MDI-X ports with a cross cable.
Note It is very difficult to distinguish cross cables and straight cables by appearance. Incorrect cables will
cause communications to fail. We recommend cascade connections with straight cables wherever possible.

System-defined Variables Related to
the Built-in EtherNet/IP Port
You can use the system-defined variables that are provided for the built-in EtherNet/IP port in programs to check the status of the built-in EtherNet/IP port.
Checking for Errors in the Built-in EtherNet/IP Port
You can check for built-in EtherNet/IP port errors, Sysmac Studio setting errors, Network Configurator setting errors, TCP/IP application errors (e.g., FTP or NTP), etc.
The following hierarchy is used. The system gives the error status at each level by logically ORing
the error status information in the next lower level.
*1. Error status variables for errors related to NX-series CPU Units are provided individually for communica-
tions port 1 and communications port 2. You can use error status variables for communications port 2 with
the NX701 CPU Units and NX102 CPU Units only.
Refer to on .
*2. With the NJ-series CPU Unit, this variable can be used with the unit version 1.11 or later.

Hierarchical Relationship of System-defined Variables Related to EtherNet/IP Errors in the
NJ-series CPU Unit
The system-defined variables that are related to EtherNet/IP errors have the following hierarchical
relationship. For example, if the value of any of the _EIP_PortErr, _EIP_CipErr, or _EIP_TcpAppErr
variables in the second level is TRUE, then the _EIP_ErrSta
variable in the first level also changes
to TRUE. Therefore, you can check the values of system-defined variables in a higher level to see
if an error has occurred for a variable in a lower level.

The meanings of the bits are shown in the following table. However, do not use the following variables in the user program: _ErrSta (Controller Error Status), _CJB_ErrSta (I/O Bus Error Status),
_CJB_MstrErrSta (I/O Bus Master Error Status), _CJB_UnitErrSta (I/O Bus Master Unit Status),
_NXB_ErrSta (NX Bus Function Module Error Status), _NXB_MstrErrSta (NX Bus Function Module
Master Error Status), and _NXB_UnitErrStaTbl (NX Bus Function Module Unit Error Status). There
may be a delay in updating them and concurrency problems in relation to the error status of the
function module. Use these variables only to access status through communications from an external device.
Bit Meaning
15 Master-detected error: This bit indicates whether the master detected a Controller error in the Unit/slave for
the error status of the Controller error.
TRUE: The master detected a Controller error
FALSE: The master has not detected a Controller error. (Valid for _CJB_UnitErrSta.)
14 Collective slave error status: This bit indicates if a Controller error was detected for levels (e.g., a Unit, slave,
axis, or axes group) that are lower than the event source (i.e., for a function module).
TRUE: A Controller error has occurred at a lower level.
FALSE: A Controller error has not occurred at a lower level. (V
_EC_ErrSta.)
