Regulations and Standards

Conformance to EU Directives

Applicable Directives

• EMC Directives

Concepts

 EMC Directive

OMRON devices that comply with EU Directives also conform to the related EMC standards so that
they can be more easily built into other devices or the overall machine. The actual products have
been checked for conformity to EMC standards.*
Whether the products conform to the standards in the system used by the customer, however, must
be checked by the customer. EMC-related performance of the OMRON devices that comply with EU
Directives will vary depending on the configuration, wiring, and other conditions of the equipment or
control panel on which the OMRON devices are installed. The customer must, therefore, perform
the final check to confirm that devices and the overall machine conform to EMC standards.

* Applicable EMC (Electromagnetic Compatibility) standards are as follows:

EMS (Electromagnetic Susceptibility): EN 61131-2
EMI (Electromagnetic Interference): EN 61131-2 (Radiated emission: 10-m regulations)

Regulations and Standards

 Conformance to EU Directives

The NY-series Controllers comply with EU Directives. To ensure that the machine or device in which
the NY-series Controller is used complies with EU Directives, the Controller must be installed as fol­lows:

• The NY-series Controller must be installed within a control panel.

• You must use the power supply in SELV specifications for the DC power supplies connected to
DC Power Supply Units and I/O Units.

• NY-series Controllers that comply with EU Directives also conform to the Common Emission Stan­dard (EN 61000-6-4). Radiated emission characteristics (10-m regulations) may vary depending
on the configuration of the control panel used, other devices connected to the control panel, wir­ing, and other conditions.
You must therefore confirm that the overall machine or equipment complies with EU Directives.

1-1 Introduction

1-1-1 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.

 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.

NY-series Industrial Panel PC / Industrial Box PC Built-in EtherNet/IP Port User’s Manual (W563)

1 Introduction

1-1-2 Features of Built-in EtherNet/IP Port on NY-series Industrial PCs

 Tag Data Links

Cyclic communications between Controllers or between Controllers and other devices are possible
on an EtherNet/IP network. Tag data links can quickly perform data exchanges.

 Message Communications

You can send CIP commands to devices on the EtherNet/IP network when required by execution of
CIP communications instructions in a program. As a result, it is possible to send and receive data
with devices on the EtherNet/IP network.

 BOOTP Client

If the NY-series built-in EtherNet/IP port 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.

 Built-in FTP Server for File Transfers to and from Host Computers

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

1-1 Introduction

1

1-1-2 Features of Built-in EtherNet/IP Port on NY-series Industrial PCs

An FTP client is built into the Controller so that 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.

 Socket Services

Socket services can be used to send/receive data between general-purpose applications and Con­trollers. You can use these communications services to send and receive any data to and from
remote nodes, i.e., between host computers 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.

 Host Names

You can directly specify IP addresses, but you can also use the host names instead of the IP
addresses for SNMP managers, or the destinations of socket instructions and CIP communications
instructions (DNS client or hosts settings). This is useful, for example, when server IP addresses
change for system revisions because the IP addresses are automatically found when host names
are used.

* A separate DNS server is necessary to use host names with the DNS client.
* 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.

* A separate SNMP manager is necessary for network management.

Additional Information

 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

 Transfer of IP Packets to Devices on Other Network Segments

The built-in EtherNet/IP ports have an IP routing function that sends IP packets to devices on other
IP network segments.

* To use the function, you must set the IP router table and default gateway settings for each device on the net-

work appropriately for your network configuration. For details on the settings, refer to 5-1 TCP/IP Settings
Display.

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, CompoNet, and DeviceNet. 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.)

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 NY-series Controller.

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, NX, and NY-series Controller. 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.

In addition, CIP messages can be routed between Windows installed in an NY-series Industrial PC and
devices on an EtherNet/IP network via the internal ports and the built-in EtherNet/IP port on the Con­troller.

1-4-2 CIP (Common Industrial Protocol) Communications Services

NY-series Industrial Panel PC / Industrial Box PC Built-in EtherNet/IP Port User’s Manual (W563)

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.

1-4-3 IP Routing

The two built-in EtherNet/IP ports on the NY-series Controller both 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.

To communicate with devices on other network segments, you must set the IP router table and default
gateway settings for the NY-series Controller and each device on the network appropriately for your
network configuration.

• You cannot create tag data links between multiple Controllers using IP routing on the NY­series Controller.

The following figure is an example of communications between the Controller in an NY-series Industrial
PC and an NJ-series Controller on a different network segment. Here, you need to set the route infor­mation for communicating via the built-in EtherNet/IP port on the NX-series Controller in the IP router
table and default gateway settings for the Controller in an NY-series Industrial PC.

The NY-series Controller provides the following functions related to the IP routing function.

Refer to 5-1 TCP/IP Settings Display for the procedure to set each function.

 IP Forward Function

This function transfers IP packets received from a network to another network.

It allows the Controller in an NY-series Industrial PC to relay IP packets between the internal com­munications network and machine networks. IP packets are transferred between the internal ports
and the built-in EtherNet/IP port on the Controller to be relayed to a different network.

If the internal communications network needs to be divided from machine networks for security rea­sons, you can set this function to disable the transfer of IP packets. When the transfer of IP packets
is disabled, the function discards IP packets that are not destined to the Controller.

 Packet Filter Function

This function checks IP packets received from a network to determine whether they should be either
received or relayed to another network.

It allows the Controller in an NY-series Industrial PC to limit the access to any machine network in
which a Controller exists via the internal port, based on a condition predefined by the user.

The function checks the IP packets received by the internal port of the Controller through the internal
communications network. It determines whether they can pass through the internal port based on a
user-specified condition.

By default, IP packets from only networks whose source IP address is set to the IP address of the
internal port will be received; otherwise, IP packets will be relayed to another network.

sequence in an ST program to execute the required communications processes. After a connection
with the other communications device is opened with an open instruction, the values of the variables
that are specified for the send instruction are sent and the data that was received for a receive instruc­tion is stored in the specified variables. The connection is closed with a close instruction, and communi­cations end. For TCP, you can also read the socket status and received data. You can use a total of 16
TCP ports and UDP ports.

2-1-2 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.

2-1-3 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)

 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 that 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 particular 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. 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 buffer overflow. Settings must be made in the Ethernet switch to enable this function
and give higher priority to tag data link packets.

2-1-2 Ethernet Switch Types

Support for the above two functions is as follows for the different types of Ethernet switches.

2-1-4 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 those functions. When you select an Ethernet switch, it is
necessary to consider whether to select the Ethernet switch based on the kind and amount of commu­nications you want to execute in the network. Refer to the following precautions when you select an
Ethernet switch. Refer to 13-2 Adjusting the Communications Load to estimate the communications
load for tag data links.

Selecting the Ethernet Switch Based on the Types of Network
Communications

 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, the amount traffic will be the same for both kinds of L2 Ethernet
switches (with or without multicast filtering).

• The tag data links are set to share the same data with all nodes in the network. (The multicast
packets are transferred to all nodes in the network, just like a broadcast.)

• The tag data link settings are all one-to-one (unicast) and multicast packets cannot be used.

If multicast filters are being used, settings must be made in the Ethernet switch. There must be
enough multicast filters for the network being used.

 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 transmission delays due
to message communications traffic and packet losses due to buffer overflow. You must make special
settings in the Ethernet switch when using the multicast filtering function and L4 QoS function.

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. (The multicast
packets are transferred to all nodes in the network, just like a broadcast.)

• 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.

2-1 Selecting the Network Devices

2

 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.

Special settings are required for an L2 Ethernet switch with multicast filtering. There must be enough
multicast filters for the network.

 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. Special settings must be made in the Ethernet switch when using the multicast filtering
function and L4 QoS function. There must be enough multicast filters for the network.

Selecting the Ethernet Switch Based on the Network
Communication Speed

 Executing Tag Data Links at a Communication Speed Over 100 Mbps

2-1-4 Precautions for Ethernet Switch Selection

If you will use data tag links with the following conditions, use an Ethernet switch with a multicast fil­ter or an Ethernet switch that supports a communication speed of 1,000 Mbps.

• Multicast

• Communication speed 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 communication and cause tag data links to be broken, even
if the device is not related to tag data link communication.

• Ask the Ethernet switch manufacturer for setting procedures for the Ethernet switch.

• Install the Ethernet switch so that its environmental resistance specifications are not

exceeded. Ask the Ethernet switch manufacturer for information on the environmental resis­tance of the Ethernet switch.

2-2 Network Installation

2-2-1 Basic Installation Precautions

• Take the greatest care when you install the Ethernet System. Be sure to follow ISO 8802-3 specifica-

tions. 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 NY-series Industrial Box PC Hardware User’s Manual (Cat. No. W556) or NY-
series Industrial Panel PC Hardware User’s Manual (Cat. No. W557).

• To obtain information on laying 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 the network so that the load does not affect communications. For example, install the tag data
links in a segment that is separate from the information network.

For the recommended clamp core and attachment method, refer to Recommended Clamp
Core and Attachment Method. To comply with EMC standards, it is mandatory that a clamp
core be attached when connecting the shield only to the connector hood on the Ethernet
switch side.

Noise immunity may be reduced and device damage may occur due to ground loops, which can
occur due to improper shield connections and grounding methods. When using a baud rate of
100 Mbps or less, it may be possible to alleviate this problem by connecting only the Ethernet
switch side as described in b), rather than connecting both ends as described in a).

Other Precautions When Laying the Twisted-pair Cable

• Press the cable connector in firmly until it locks into place at both the Ethernet switch and the built-in

EtherNet/IP port.

• Do not lay the twisted-pair cable together with high-voltage lines.

• Do not lay the twisted-pair cable near devices that generate noise.

• Do not lay the twisted-pair cable in locations subject to high temperatures or high humidity.

• Do not lay the twisted-pair cable in locations subject to excessive dirt and dust or to oil mist or other

contaminants.

2-2-4 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’s power supply. 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

• To connect Ethernet switches with twisted-pair cables, observe the followings:

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.

2-2 Network Installation

2

2-2-4 Precautions When Installing and Connecting Ethernet Switches

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 whenever possible.

• Some Ethernet switches can automatically distinguish between MDI and MDI-X. When this kind of
Ethernet switch is used, straight cable can be used between Ethernet switches.

Adjust the built-in EtherNet/IP port’s link settings to match the communications settings of the
connected Ethernet switch. If the settings do not match, the link will be unstable and prevent nor­mal communications. The following table shows the allowed settings for each Ethernet switch
communications mode. (Auto-Nego: Auto negotiation, Full: Full duplex, Half: Half duplex)

Hierarchical Relationship of System-defined Variables Related to EtherNet/IP Errors in the
NY-series Controller

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 _EIP1_PortErr, _EIPIn1_PortErr, and
_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.

4-1 IP Addresses

4-1-1 IP Address Configuration

IP addresses are made up of 32 bits of binary data that specify the network number (net ID) and host
number (host ID). The network number identifies the network, and the host number identifies the node
(or host) on the network. IP addresses are divided into three classes, A, B, and C, so that the address
system can be selected according to the scale of the network. (Classes D and E are not used.)

The number of networks in each class and the number of hosts possible on the network differ according
to the class.

Class Number of networks Number of hosts

Class A Small

Class B Medium

Class C Large

The 32 bits of binary data in an IP address are divided into four sections of eight bits each. IP
addresses are represented by the decimal equivalent of each of the four octets in the 32-bit address,
each separated by a period.

For example, the binary address 10000010 00111010 00010001 00100000 would be represented as

130.58.17.32.

4-1-2 Allocating IP Addresses

You must assign IP addresses nodes so that each IP address is assigned only once in the network or
between several networks.

4-1-3 Subnet Masks

Operation and management of a network can become very difficult if too many nodes are connected on
a single network. In such a case it can be helpful to configure the system so that a single network is
divided up into several subnetworks. Internally the network can be treated as a number of subnetworks,
but from the outside it acts as a single network and uses only a single network ID. To establish subnet­works, the host ID in the IP address is divided into a subnet ID and a host ID by using a setting called
the subnet mask. The subnet mask indicates which part of the host ID is to be used as the subnet ID.
All bits in the subnet mask that correspond to the bits in the IP address used either as the network ID or
subnet ID are set to “1,” and the remaining bits, which correspond to the bits in the IP address actually
used for the host ID, are set to “0.”

The following example shows the subnet mask for an 8-bit subnet ID used in class-B IP addresses.

Host IDSubnet IDNetwork ID

Set the same subnet mask for all of the nodes on that subnetwork. The built-in EtherNet/IP port sup­ports CIDR (Classless Inter-Domain Routing). The subnet mask can be set to 192.0.0.0 to

255.255.255.252. If subnetworks are not used, set the following subnet mask values for IP address
classes A to C.

Class Subnet mask

Class A 255.0.0.0

Class B 255.255.0.0

Class C 255.255.255.0

A network address is information derived from a subnet mask and used to identify each network. A net­work address enables users to determine whether multiple nodes belong to the same network. A net­work address is calculated by performing a logical AND operation on the IP address and subnet mask
of a node.

The following are examples of network address calculation.

In this example, the IP address of node 1 is set to 192.168.250.20, the IP address of node 2 is set to

192.168.245.30, and the subnet mask is set to 255.255.240.0. The network addresses of the two nodes
are calculated as follows.

4 Determining IP Addresses

As shown in the above table, node 1 and node 2 have the same network address, which means these
nodes belong to the same network.

4-1-4 CIDR

CIDR, or classless interdomain routing, is used to assign IP addresses that do not use classes. IP
addresses that use classes are separated into blocks according to network IDs and host IDs, resulting
in inefficient usage of IP address space. CIDR does not use classes, so IP address space can be
divided as required to more efficiently use IP address space. For example, using a subnet mask setting
with CIDR enables building a horizontally distributed network exceeding 254 nodes even if a class C
address block (e.g., 192, 168...) is used.

Use one of the following methods to set the IP address for the built-in EtherNet/IP port on the NY-series
Controller. The IP address for the internal port can be set only by using a user-specified address.

Setting a User-specified IP Address

If you need to change the default IP address of the built-in EtherNet/IP port or if you need to use the
built-in EtherNet/IP port with another EtherNet/IP node, set the IP address to the required value.

For an NX-series CPU Unit, you cannot set IP addresses that make two built-in EtherNet/IP ports
belong to the same network.

Automatically Obtaining the IP Address from the BOOTP Server

There are two methods to automatically obtain an IP address.

• Obtain the IP address from the BOOTP server each time the power is turned ON.

• Obtain the IP address from the BOOTP server once when the power is turned ON and then do not

allow it to change.

4-3 Private and Global Addresses

4-3-1 Private and Global Addresses

There are two kinds of IP addresses, private and global.

IP address Description

Global address These are IP addresses that connect directly to the Internet.

Allocated by application to NIC, each address is unique in
the world, and as many as 4.3 billion can be allocated world­wide.

Private address These are IP addresses for Intranet (LAN) use. Direct con-

nection to the Internet is not possible. Frames that include
private IP addresses are restricted by the router from being
sent outside the LAN.

Generally, as shown below, global addresses in the intranet are allocated only to IP routers (such as
broadband routers) interfaced with the Internet. All other nodes in the intranet, which includes the built­in EtherNet/ IP port, are allocated private addresses.

 Conditions for Communications Applications

If the built-in EtherNet/IP port uses a private address, you can use explicit message communica­tions service under the following conditions.

• The explicit message communications service can be executed on the intranet between built-in
EtherNet/IP ports with private addresses only.

• A device such as a personal computer (CIP applications including the Network Configurator) can­not connect online and communicate over the Internet with a built-in EtherNet/IP port that has a
private address. Explicit message communications are also not possible over the Internet
between built-in EtherNet/IP ports with private addresses.

Network Security and Firewalls

To set up an intranet through a global address involves network security considerations. Be sure
to consult with a network specialist in advance and consider installation of a firewall. After a fire­wall has been set up by a communications company technician, there may be some applications
that cannot be used. Be sure to check first with the communications company technician.

line, rather than for a general line such as a broadband line. Also, be sure to consult with a net­work specialist and consider security measures such as a firewall. After a firewall has been set
up by a communications technician, there may be some applications that cannot be used. Be
sure to check first with the communications technician.
