!WARNING Provide safety measures in external circuits (i.e., not in the Programmable

Controller), including the following items, to ensure safety in the system if an
abnormality occurs due to malfunction of the PLC or another external factor
affecting the PLC operation. Not doing so may result in serious accidents.

• Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.

• The PLC will turn OFF all outputs when its self-diagnosis function detects
any error or when a severe failure alarm (FALS) instruction is executed.
As a countermeasure for such errors, external safety measures must be
provided to ensure safety in the system.

• The PLC outputs may remain ON or OFF due to deposits on or burning of
the output relays, or destruction of the output transistors. As a counter­measure for such problems, external safety measures must be provided
to ensure safety in the system.

• When the 24-V DC output (service power supply to the PLC) is over­loaded or short-circuited, the voltage may drop and result in the outputs
being turned OFF. As a countermeasure for such problems, external
safety measures must be provided to ensure safety in the system.

!Caution Execute online editing only after confirming that no adverse effects will be

caused by extending the cycle time. Otherwise, the input signals may not be
readable.

• Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.

!Caution Fail-safe measures must be taken by the customer to ensure safety in the

event of incorrect, missing, or abnormal signals caused by broken signal lines,
momentary power interruptions, or other causes. Serious accidents may
result from abnormal operation if proper measures are not provided.

!Caution Confirm safety at the destination node before changing or transferring to

another node the contents of a program, the PLC Setup, I/O tables, I/O mem­ory, or parameters. Changing or transferring any of these without confirming
safety may result in injury.

!Caution Tighten the screws on the terminal block of the AC Power Supply Unit to the

torque specified in the operation manual. The loose screws may result in
burning or malfunction.

Application Precautions 5

• Always use the power supply voltages specified in the operation manuals.
An incorrect voltage may result in malfunction or burning.

• Take appropriate measures to ensure that the specified power with the
rated voltage and frequency is supplied. Be particularly careful in places
where the power supply is unstable. An incorrect power supply may result
in malfunction.

• Install external breakers and take other safety measures against short-cir­cuiting in external wiring. Insufficient safety measures

• Make sure that all the Backplane mounting screws, terminal block screws,
and cable connector screws are tightened to the torque specified in the
relevant manuals. Incorrect tightening torque may result in malfunction.

• Leave the label attached to the Unit when wiring. Removing the label may
result in malfunction if foreign matter enters the Unit.

• Remove the label after the completion of wiring to ensure proper heat dis­sipation. Leaving the label attached may result in malfunction.

• Use crimp terminals for wiring. Do not connect bare stranded wires
directly to terminals. Connection of bare stranded wires may result in
burning.

• Observe the following precautions when wiring the communications
cable.

• Separate the communications cables from the power lines or high-ten­sion lines.

• Do not bend the communications cables past their natural bending ra­dius.

• Do not pull on the communications cables.

• Do not place heavy objects on top of the communications cables.

• Always lay communications cable inside ducts.

• Use appropriate communications cables.

• Make sure that the terminal blocks, expansion cable connectors, and
other items with locking devices are locked in place.

• Wire all connections correctly according to instructions in this manual.

• Double-check all wiring and switch settings before turning ON the power
supply. Incorrect wiring may result in burning.

• Mount Units only after checking terminal blocks and connectors com­pletely.

• Check the user program (ladder program and other programs) and
parameters for proper execution before actually running it on the Unit. Not
checking the program may result in unexpected operation.

• Confirm that no adverse effect will occur in the system before attempting
any of the following. Not doing so may result in an unexpected operation.

• Changing the operating mode of the PLC.

• Force-setting/force-resetting any bit in memory.

• Changing the present value of any word or any set value in memory.

• After replacing Units, resume operation only after transferring to the new
CPU Unit and/or Special I/O Units the contents of the DM Area, HR Area,
programs, parameters, and other data required for resuming operation.
Not doing so may result in an unexpected operation.

• Before touching a Unit, be sure to first touch a grounded metallic object in
order to discharge any static build-up. Not doing so may result in malfunc­tion or damage.

xxiv

Conformance to EC Directives 6

• When transporting the Unit, use special packing boxes and protect it from
being exposed to excessive vibration or impacts during transportation.

• CPU Bus Units will be restarted when routing tables are transferred from
a Programming Device to the CPU Unit. Restarting these Units is required
to read and enable the new routing tables. Confirm that the system will
not be adversely affected before allowing the CPU Bus Units to be reset.

• When the EtherNet/IP Unit's settings (IP address or tag data link settings)
are transferred from a Programming Device, all of the destination Ether­Net/IP Units (nodes) will be reset in order to enable the transferred set­tings. Transfer settings to the EtherNet/IP Units only after verifying that
restarting the Units will not cause any problems in the system.

• If a repeater hub is used for EtherNet/IP tag data links (cyclic communica­tions), the network's communications load will increase, data collisions
will occur frequently, and stable communications will be impossible.
Always use a switching hub when using tag data links in the network.

• Before resetting a CPU Bus Unit or Special I/O Unit, always verify that
restart the Unit will not cause any problems in the system.

6-2 Concepts

EMC Directives

OMRON devices that comply with EC 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 (see the following note). 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 EC 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.

Note Applicable EMS (Electromagnetic Susceptibility) and EMI (Electromagnetic

EtherNet/IP Unit Overview Section 1-1

1-1 EtherNet/IP Unit Overview

1-1-1 EtherNet/IP Features

EtherNet/IP is an industrial multi-vendor network that uses Ethernet compo­nents. 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. Since EtherNet/IP uses standard Ethernet technology, various gen­eral-purpose Ethernet devices can be used in the network. EtherNet/IP has
the following features.

The CIP has the following advantages.

• Destination nodes are specified by a relative path, without a fixed routing
table.

• 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.
Since the producer can send the same data with the same characteristics
in a multicast (either multicast or unicast can be selected), the time
required for the transfer is fixed and not dependent on the number of con­sumer nodes.

Note The CIP (Common Industrial Protocol) is a shared industrial protocol for the

OSI application layer. The CIP is used in networks such as EtherNet/IP, Con­trolNet, and DeviceNet. Data can be routed easily between networks that are
based on the CIP, so a transparent network can be easily configured from the
field device level to the host level.

High-speed, High-capacity Data Exchange through Data Links

The EtherNet/IP protocol supports implicit communications, which allows
cyclic communications (called tag data links in this manual) with EtherNet/IP
devices. Data can be exchanged at high speed between Controllers and
devices, using high-volume tag sets (up to 184, 832 words) between PLCs.

Tag Data Link (Cyclic Communications) Cycle Time

Tag data links (cyclic communications) can 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 synchronicity of the connection’s data is pre­served.

Since the refresh cycle can be set for each connection, each application can
communicate at its ideal refresh cycle. For example, a processes interlocks
can be transferred at high speed while the production commands and the sta­tus monitor information are transferred at low speed.

Note The communications load to the nodes must be within the Units’ allowed com-

munications bandwidth.

Multi-vendor Communications with CIP Messages

Data can be exchanged with a variety of devices connected by EtherNet/IP
because it supports the standard CIP (Common Industrial Protocol) message
communications.

3

EtherNet/IP Unit Overview Section 1-1

Communicating with FINS Messages (FINS/TCP and FINS/UDP)

Data can be exchanged with other OMRON FA devices using SEND, RECV,
and CMND instructions from the ladder program, because EtherNet/IP sup­ports OMRON’s standard FINS message communications services.

There are two kinds of message services, using UDP/IP and TCP/IP (called
FINS/UDP and FINS/TCP), allowing flexible data exchange for different appli­cations.

Note There are no particular restrictions when sending FINS messages to OMRON

Ethernet Units (CS1W-ETN21 or CJ1W-ETN21) in an Ethernet network.

Network Connections with DeviceNet Devices

When a PLC has an EtherNet/IP Unit and DeviceNet Unit mounted, the PLC
can be used as a gateway to exchange data with DeviceNet Devices through
CIP messages.

Network Connections with Controller Link

Mutual connections of Controller Link and EtherNet/IP are also supported
(using the FINS communications service). The Controller Link connection
allows a PLC on the Controller Link network to be monitored from a PLC on
the EtherNet/IP network. Conversely, data can be exchanged with a PLC on
the EtherNet/IP network from a PLC on the Controller Link network.

Plentiful Troubleshooting Functions

A variety of functions are provided to quickly identify and handle errors.

• Self-diagnosis at power ON

• PING command to check the connection with another node

• Error Log functions record the time of occurrence and other error details

1-1-2 System Configuration

The devices shown in the following table are required to configure a network
with CS1W-EIP21 and CJ1W-EIP21 EtherNet/IP Units, so prepare them in
advance.

Recommended Switching
Hubs

For details on recommended devices for constructing a network, refer to 4-4-2
Recommended Products.

Note If a repeater hub is used for EtherNet/IP tag data links (cyclic communica-

tions), the network’s communications load will increase, data collisions will
occur frequently, and stable communications will be impossible. Always use a
switching hub when using tag data links in the network.

1-1-4 Setup Area and Related Programming Devices

Use the Network Configurator to make the EtherNet/IP Unit’s TCP/IP settings
and device parameter settings. Both of these settings are stored in the Ether­Net/IP Unit’s non-volatile memory.

Note Unlike the Ethernet Units, the EtherNet/IP Unit’s TCP/IP settings are not

stored in the CPU Unit’s CPU Bus Unit System Setup Area. The settings are
stored in the EtherNet/IP Unit itself.

■ TCP/IP Settings

The TCP/IP settings are settings such as the local IP address and subnet
mask. Connect the Network Configurator online to the CS/CJ-series PLC,

select Tools

− Setup TCP/IP Configuration, and make the settings in the

Setup TCP/IP Configuration Window.

■ Device Parameter Settings

The EtherNet/IP Unit’s device parameters are made up of communications
settings such as the tag data link setting parameters, FINS/UDP settings, and
FINS/TCP settings. Double-click the EtherNet/IP Unit in the Network Configu­rator’s right pane to display the Edit Device Parameters Dialog Box, and make
the necessary settings in the Connections Tab, Tag Sets Tab, Status Area
Tab, and FINS Configuration Tab.

Making Settings in the
Routing Table Area
(with CX-Integrator)

OMRON Communications Units use OMRON's original FINS network system.
Make the settings for the FINS network and the relay path, as required, in the
Routing Table Area allocated to the non-volatile memory in the CPU Unit.

Use CX-Integrator to make the settings. (CX-Integrator is software that comes
with the CX-One and is automatically installed when the CX-One is installed.)
Each time the EtherNet/IP Unit is turned ON or restarted, it reads and uses
the contents of the Routing Table Area as the settings for FINS network.

1-1-5 Communications Services Overview

The following communications services are supported.

CIP (Common Industrial Protocol) Communications Services

Tag Data Links
(Cyclic Communications)

A program is not required to perform cyclic data exchanges with other devices
in the EtherNet/IP network.

Normally, the tag data links in an EtherNet/IP Unit are started by grouping the
tags created with the Network Configurator into a tag set, and establishing a
connection with the target device using that group of tags. One connection is
used per group (tag set). Up to 256 connections can be registered.

Note In this example, a connection is established with the originator’s tag list con-

taining tags a to g (inputs), which are grouped in a tag set called SP1_IN, and
the target’s tag list containing tags i and ii (outputs), which are grouped in a
tag set called SP1_OUT.

Message Communications
(Unconnected Message
Service)

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 CMND instruction from the CS/
CJ-series CPU Unit’s user program (without using a connection).

(With an NE1S-series CPU Unit, use the CSND instruction to send CIP com­mands.)

EtherNet/IP Unit Overview Section 1-1

CIP messages (CIP commands and responses) can also be transferred to
another CIP-based network via the EtherNet/IP Unit using the CIP routing
function for message communications.

In the CS/CJ Series, CIP routing is possible only through two EtherNet/IP
Units. In the NE1S Series, CIP routing is possible through a DeviceNet Unit or
ControlNet Unit as well as another EtherNet/IP Unit.

FINS Communications
Service

FINS commands can be sent to or received from other PLCs or computers on
the same Ethernet network by executing SEND(090), RECV(098), or
CMND(490) instructions in the ladder diagram program. This enables various
control operations such as the reading and writing of I/O memory between
PLCs, mode changes, and file memory operations.

Note There are no particular restrictions when sending FINS messages to OMRON

Ethernet Units (CS1W-ETN21 or CJ1W-ETN21) in an Ethernet network.

EtherNet/IP Unit Overview Section 1-1

Various control operations (such as the reading and writing of I/O memory
between PLCs, mode changes, and file memory operations) can be executed
from the host computer by sending the corresponding FINS command with a
UDP/IP or TCP/IP header attached.

For example, it is possible to connect online via Ethernet from FINS communi­cations applications such as the CX-Programmer, and to perform remote pro­gramming and monitoring. (See note.)

Note Use CX-Programmer version 4.0 to use TCP/IP. For lower versions of CX-Pro-

grammer, FinsGateway Version 2003 or higher is required to use TCP/IP.

The FINS gateway function enables access to PLCs on not only the same
Ethernet network but on various other networks, including SYSMAC LINK and
Controller Link.

1-1-6 IP Routing Service (NE1S Series Only)

TCP/IP or UDP/IP packets can be transmitted transparently between the CPU
Unit and the EtherNet/IP Network. The IP routing function (IP over Control­Net) enables TCP/IP or UDP/IP communications between the ControlNet net­work connected through the ControlNet Unit and the Ethernet network
connected through the CPU Unit’s built-in Ethernet port. The CIP communica­tions service cannot be used with IP over ControlNet. IP (Internet Protocol)
communications are performed using the ControlNet as the network interface
layer. The CPU Unit treats the ControlNet Unit as an NIC (Network Interface
Card).

Note When using the IP routing function, do not connect the EtherNet/IP Unit’s

Ethernet port in the same network as a CPU Unit’s built-in Ethernet port. If
these ports are connected, an IP address duplication will be detected and the
EtherNet/IP Unit will be unable to communicate.

1-3-2 Switch Settings

Unit Number Setting
Switch

The Unit Number Setting Switch sets the EtherNet/IP Unit’s unit number as a
CPU Bus Unit. The unit number determines which data area words are allo­cated to the Unit to contain data such as control bits, flags, status information,
and connection information.

Note The unit number is factory-set to 0.

The unit number can be set to any number in the setting range (0 to F), as
long as the same number is not set on another CPU Bus Unit in the same
PLC.

Note (1) Use a small screwdriver to make the setting, and be sure not to damage

the rotary switch.

(2) Always turn OFF the PLC’s power supply before setting the unit number.

(3) The unit number is factory-set to 0.

(4) If the same unit number is set on more than one CPU Bus Unit mounted

in a PLC, a unit number duplication error will occur in the PLC and the
EtherNet/IP Unit will not be able to start operating.

Node Address Setting
Switch

The Node Address Setting Switch sets the EtherNet/IP Unit’s node address.

Note The node address is factory-set to 01. With the default settings, the values set

on these switches become the last two digits of the EtherNet/IP Unit’s IP
address.

Default IP address = 192.168.250.node address
With the factory-default node address setting of 01, the default IP address is

192.168.250.1.

Design Procedures Section 2-1

2-1 Design Procedures

This section describes how to design an EtherNet/IP system in the following
two cases.

(1) Establishing a new EtherNet/IP system

(2) Modifying an established EtherNet system

2-1-1 Establishing a New EtherNet/IP System

This section describes how to use the Network Configurator to construct a
new EtherNet/IP system by designing the new system and downloading the
parameters to the network devices.

Selecting a Switching
Hub

Always use a switching hub when using tag data links. Select a switching hub
with the functions required for the communications being used in the network.

Refer to 2-2 Selecting the Network Devices.

System Design and Programming (Offline Operations)

1. Starting the Network Configurator

Start the Network Configurator.

Refer to ???7-2-1 Starting and Network Configurator.

2. Registering Devices

Use the Network Configurator to register devices in the EtherNet/IP net­work.

Refer to ???7-2-3 Registering Devices.

3. Setting Device Parameters

Set the device parameters (communications settings such as tag data link
parameters, FINS/UDP settings, and FINS/TCP settings) for each device
in the network configuration.

Refer to ???7-2-4 Creating Tag Sets and ???7-2-5 Setting the Con-
nections with Target Devices.

4. Verifying the Network Bandwidth Being Used

The network’s communications load capacity is called the bandwidth. Ver­ify that the bandwidth used by the EtherNet/IP tag data links does not ex­ceed the allowed network bandwidth.

If the bandwidth exceeds the allowed level, adjust the packet interval (RPI).

Refer to 2-3 Checking Bandwidth Usage and Adjusting the Packet In-
terval (RPI).

5. Calculating and Verifying the Maximum Response Time

Calculate the maximum response time of all of the tag data links, and verify
that the response time meets the required specifications. If the response
time does not meet the required specifications, evaluate and correct the
network configuration by taking steps such as dividing the network.

Refer to ???Section 11 Communications Performance and Communi-
cations Load.

6. Saving the Network Configuration File

Save the network configuration file with the completed design.

Refer to ???7-2-11 Saving the Network Configuration File.

23

Design Procedures Section 2-1

7. Closing the Network Configurator

The next steps are wiring the network and connecting the Network Configura­tor to the network.

Constructing the
Actual System

Wire the network, install the actual devices, and set the devices’ IP
addresses.

8. Clearing the Devices’ Various Parameters

Clear the various parameters stored in the new devices that will be used in
the system.

Refer to ???7-2-10 Clearing Device Parameters.

Note Before connecting newly added devices to the network, clear the parameters

set in the devices. The EtherNet/IP Unit will restart automatically when the
Unit’s device parameters are cleared (reset) from the Network Configurator.
The Unit must restart in order to enable the cleared parameter settings
(default settings). Clear (reset) the device parameters only after verifying that
restarting the Unit will not cause any problems in the system.

9. Changing the Devices’ IP Addresses

Set the actual devices’ IP addresses. Any of the following methods can be
used to set the EtherNet/IP Unit’s local IP address.

• If you want to connect the EtherNet/IP Unit immediately, the default IP
address is 192.168.250.node address. (The node address is set with
the Node Address Setting Switches on the front of the Unit.)

• If you want to set a particular IP address and set (store) that local IP
address in the CPU Unit, set it with the CPU Unit’s allocated DM Area
words.

• If you want to set a particular IP address and set (store) that local IP
address in the EtherNet/IP Unit, set the TCP/IP with the Network Con­figurator.
Refer to ???4-8 TCP/IP Settings.

Note (1) Before connecting a device to the network, set a suitable IP address for

the device.

(2) When setting the EtherNet/IP Unit’s local IP address with the Network

Configurator, connect the Units one at a time, and download the TCP/IP
setting parameters.
The EtherNet/IP Unit will restart automatically when the TCP/IP setting
parameters are downloaded to the Unit from the Network Configurator.
The Unit must restart in order to enable the parameter settings. Download
the TCP/IP setting parameters only after verifying that restarting the Unit
will not cause any problems in the system.

Selecting the Network Devices Section 2-2

Note (1) Always use a switching hub when using tag data links in the network.

(2) If a repeater hub is used for EtherNet/IP tag data links (cyclic communi-

cations), the network’s communications load will increase, data collisions
will occur frequently, and stable communications will be impossible.

2-2-2 Switching Hub Types

Layer 2 (L2) Switching
Hub

These switching hubs use the Ethernet MAC address to switch ports. Ordi­nary switching hubs have this function.

Layer 3 (L3) Switching
Hub

These switching hubs use the Ethernet MAC address or IP address to switch
ports. When using an EtherNet/IP Unit, select from the following functions.

• L2 switch without multicast filtering function

• L2 switch with multicast filtering function

• L3 switch with multicast filtering function and L2/L3 QoS function

2-2-3 Switching Hub Functions

This section describes the switching hub functions which are important when
using an EtherNet/IP network.

Multicast Filter The multicast filter transfers multicast packets to the specific nodes only. This

function is implemented in the switching hub as IGMP Snooping or GMRP.
“Specific nodes” are nodes equipped with an IGMP client that have made
transfer requests to the switching hub. (OMRON EtherNet/IP Units are
equipped with an IGMP client.)

When the hub does not use the multicast filter, multicast packets are sent to
all nodes, just like broadcast packets, which increases the traffic in the net­work. Settings must be made in the switching hub to enable this function.

Layer 3/4 QoS (Quality of
Service) Function

This function controls the priority of packet transmissions, so that packets can
be sent with higher priority to a particular IP address and TCP (UDP) port.

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 switching hub to
enable this function and give higher priority to tag data link packets.

2-2-4 Precautions When Selecting a Switching Hub

The functions supported by the switching hub may affect tag data link trans­mission delays and the configuration. In addition, if the switching hub supports
advanced functions, special settings are required for those functions.

Selecting the Network Devices Section 2-2

When selecting a switching hub, it is necessary to consider whether the
switching hub will be selected based on the kind of communications that will
be performed in the network or the kind of switching hub that you want to use.
Refer to the following precautions when selecting a switching hub.

Selecting the Switching Hub Based on the Types of Network Communications

Executing Tag Data Links
Only

We recommend using an L2 switching hub without multicast filtering or an L2
switching hub with multicast filtering.

Using an L2 switching hub 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 switching hubs (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 the multicast filter function is being used, settings must be made for that
function in the switching hub.

Executing Tag Data Links
and Message
Communications

We recommend using an L3 switching hub with multicast filtering and L3/L4
QoS.

By setting 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. Settings must be made in the
switching hub to enable this function and give higher priority to tag data link
packets.

Special settings must be made in the switching hub when using the multicast
filtering function and L3/L4 QoS function.

Selecting the Switching Hub Based on the Hub’s Supported Functions

L2 Switching Hub without
Multicast Filtering

We recommend this kind of switching hub 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 switching hub without multicast fil­tering.

L2 Switching Hub with
Multicast Filtering

We recommend this kind of switching hub 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 switching hub with multicast filtering.

L3 Switching Hub with
Multicast Filtering and L3/
L4 QoS Functions

We recommend this kind of switching hub when both tag data links and mes­sage communications are executed.

30

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

By setting 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. Settings must be made in the
switching hub to enable this function and give higher priority to tag data link
packets.

Special settings must be made in the switching hub when using the multicast
filtering function and L3/L4 QoS function.

2-3 Checking Bandwidth Usage and Adjusting the Packet

Interval (RPI)

In an Ethernet network using a switching hub, the network bandwidth is not
shared by all of the nodes; independent transmission paths are established
between individual nodes through the switching hub.

A dedicated communications buffer is established in the switching hub for
communications between the nodes and full-duplex communications (simulta­neous transmission and reception) are performed asynchronously with other
transmission paths. The communications load in other transmission paths
does not affect communications, so packet collisions do not occur and stable,
high-speed communications can be carried out.

The switching hub functions shown in the following table are some of the fac­tors determining the performance of tag data links.

The following table shows the tag data link settings that can be made for indi­vidual EtherNet/IP Units as well as the setting ranges.

When the tag data link settings exceed the capabilities of the switching hub
being used, adjust (increase) the packet interval (RPI) value and set it again.
In addition, if the required tag data link performance cannot be achieved with
the switching hub’s capabilities, reevaluate the overall network configuration
and correct it by taking steps such as selecting a different switching hub or
splitting the network.

The following sections show how to check the network bandwidth being used
by the tag data links in the designed network, and how to set the appropriate
values.

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

2-3-1 Checking the Tag Data Links’ Bandwidth Usage

The Network Configurator can display the bandwidth actually used for tag
data links at each EtherNet/IP Unit, based on the connections set in the net­work configuration.

The device bandwidth used by tag data links can be checked by clicking the
Detail Button in the Usage of Device Bandwidth Area at the bottom of the Net­work Configuration Window.

The display shows the percentage of the allowed tag data link bandwidth used
(Usage of Capacity), as well as the network bandwidth used (Mbit/s).

The percentage of the allowed tag data link bandwidth used (Usage of Capac­ity) depends on the packet interval (RPI) setting.

The percentage of the allowed tag data link bandwidth used (Usage of Capac­ity) will increase as the packet interval (RPI) setting is shortened. Conversely,
the percentage of the allowed tag data link bandwidth used (Usage of Capac­ity) will decline as the packet interval (RPI) setting is lengthened.

The packet interval (RPI) can be set in any one of the following ways.

• Setting the same interval for all connections

• Setting a particular device’s connection

• Setting a particular connection

When the same packet interval (RPI) is set for all connections, the percentage
of the allowed tag data link bandwidth used (Usage of Capacity) will basically
increase proportionally as the packet interval (RPI) is made faster.

Example:
If the packet interval (RPI) is set to 50 ms for all connections and the tag
data link bandwidth used (Usage of Capacity) is 40%, the Usage of Capac­ity may increase to 80% when the packet interval (RPI) is reduced to 25
ms for all connections.

Note We recommend using less than 80% of the allowed tag data link bandwidth

(Usage of Capacity). Even if the Usage of Capacity is less than 80%, time­outs and other communications problems may occur during temporary net­work loads such as Network Configurator monitoring operations or message
communications by user applications. If this kind of communications problem
occurs, lengthen some or all of the nodes’ packet interval (RPI) settings to
reduce the Usage of Capacity.
Even if the Usage of Capacity is between 80% and 100%, it will still be possi­ble to establish connections and perform message communications through
the Network Configurator, but time-outs are likely to occur during message
communications.

32

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

2-3-2 Checking the Device Bandwidth Usage and Resetting the RPI

The percentage of the allowed tag data link bandwidth used (Usage of Capac­ity) can be checked offline by inputting the packet interval (RPI) values in the
Network Configurator’s tag data link connection settings. Check the Usage of
Capacity and change the packet interval (RPI) settings.

If the required communications performance cannot be achieved by changing
the settings, reevaluate the network starting with the network configuration.

1,2,3... 1. Make the required settings in the Network Configurator’s Network Config-

uration Window.

2. Click the Detail Button in the Usage of Device Bandwidth Area at the bot­tom of the Network Configuration Window.

The Usage of Device Bandwidth Area Dialog Box will be displayed.

The Usage of Capacity column will show the percentage of the allowed tag
data link bandwidth being used, and the Mbit/s column will show the network
bandwidth (baud rate) being used.

3. The percentage of the allowed tag data link bandwidth being used (Usage
of Capacity) can be adjusted by changing the associated devices’ packet
interval (RPI) settings. The packet interval (RPI) settings can be adjusted
with the following 3 methods.

33

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

Method 1: Same Packet Interval Set for all Connections

The Usage of Capacity can be adjusted by changing the packet interval
(RPI) for all of the connections together.

a. Click the Set Packet Interval (RPI) Button at the bottom of the Usage

of Device Bandwidth Dialog Box.

b. The Set Packet Interval (RPI) Dialog Box will be displayed. Input a new

packet interval (RPI) value, and click the OK Button.

Method 2: Changing a Particular Device’s Packet Interval (RPI) Set­ting

The Usage of Capacity can be adjusted for only a particular device by
changing the packet intervals (RPI) for all of the device’s connections to­gether.

In this case, the Usage of Capacity will also change for the devices that are
the target devices of the connection which was adjusted.

34

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

a. Click the Set Packet Interval (RPI) Button at the bottom of the Usage

of Device Bandwidth Dialog Box.

b. The Set Packet Interval (RPI) Dialog Box will be displayed. In the Tar -

get Device Area, deselect the target devices that are not being adjust­ed by removing the check marks.

c. Input a new packet interval (RPI) value, and click the OK Button.

Method 3: Changing a Particular Connection’s Packet Interval (RPI)
Setting

The Usage of Capacity can be adjusted by individually changing the packet
intervals (RPI) setting for a particular connection.

In this case, the Usage of Capacity will also change for the device that is
the target device of the connection which was adjusted.

35

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

a. Click the Close Button at the bottom of the Usage of Device Bandwidth

Dialog Box.

b. Double-click the device that is set as the originator of the desired con-

nection. The Edit Device Parameters Dialog Box will be displayed.

36

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

c. In the Register Device List, select the connection for which you want

to change the packet interval (RPI), and click the Edit Button.

d. The device’s Edit Connections Dialog Box will be displayed. Input a

new packet interval (RPI) value, and click the OK Button.

4. If the packet interval (RPI) cannot be adjusted to the desired value by the
three preceding methods, evaluate the network configuration itself and
consider taking the following steps.

• Reduce the number of nodes and number of connections.

37

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

• Split the network.

5. Check the bandwidth usage again.

If the connection settings have been changed, click the Detail Button in the
Usage of Device Bandwidth Area at the bottom of the Network Configura­tion Window. Verify that the allowed tag data link bandwidth used (Usage
of Capacity) is less than 100%.

It is particularly important to check the Usage of Capacity when an individ­ual connection’s packet interval (RPI) setting was changed without using
the Set Packet Interval (RPI) Button at the bottom of the Usage of Device
Bandwidth Dialog Box.

6. Run user tests to verify that there are no problems with the new settings.

2-3-3 Packet Interval (RPI) Setting Examples

The following examples explain how to calculate the packet intervals (RPI) in
the following network configuration.

Example Conditions

Connections

In this example, there are 10 CS1W-EIP21 Units and 10 CJ1W-EIP21 Units
for a total of 20 devices connected in the network. Each device has one 100­word tag for transmission and nineteen 100-word tags for reception, so that
the Units exchange data mutually.

38

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

By default, the packet intervals (RPI) are set to 50 ms for all of the connec­tions. The devices’ IP addresses range from 192.168.250.1 to

192.168.250.20.

Checking the Device
Bandwidth Usage

When the Detail Button is clicked in the Usage of Device Bandwidth Area, it is
apparent that the percentage of the allowed tag data link bandwidth being
used by each device’s tag data link (Usage of Capacity) is 36.67%, as shown
in the following dialog box.

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

Changing the
Settings

Method 1: Same Packet Interval Setting for All Connections

The percentage of the allowed tag data link bandwidth being used (Usage of
Capacity) was 36.67% with the packet interval (RPI) set to 10.0 ms for all of
the connections, so the packet interval (RPI) will be set to 4.5 ms, which is
about one-half of the original setting.

Click the Set Packet Interval (RPI) Button at the bottom of the Usage of
Device Bandwidth Dialog Box. The Set Packet Interval (RPI) will be displayed.
Input 4.5 ms as the new packet interval (RPI) value, and click the OK Button.

40

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

The percentage of the allowed tag data link bandwidth being used (Usage of
Capacity) increases to 77.41% and the same packet interval (RPI) is set for all
of the connections, which indicates that 4.5 ms is the fastest packet interval
(RPI).

Method 2: Changing a Particular Device's Packet Interval (RPI) Setting

In this example, we want faster tag data links for devices 192.168.250.1 and

192.168.250.10 only. Click the Set Packet Interval (RPI) Button at the bottom

of the Usage of Device Bandwidth Dialog Box to display the Set Packet Inter­val (RPI) Dialog Box.

41

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

In the Target Device Area, deselect all devices other than 192.168.250.1 and

192.168.250.10 by removing the corresponding check marks. Input 4.5 ms as

the new packet interval (RPI) value, and click the OK Button.

42

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

The percentage of the allowed tag data link bandwidth being used (Usage of
Capacity) increases to 79.07% for devices 192.168.250.1 and

192.168.250.10, which indicates that the packet interval (RPI) is set to a

higher speed for these devices’ connections.

The Usage of Capacity values also indicate that the Usage of Capacity has
increased (from 36.67% to 40.37%) for all of the other devices, which connect
with devices 192.168.250.1 and 192.168.250.10.

43

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

Method 3: Changing Only a Particular Connection's Packet Interval (RPI)

In this example, we want a faster tag data links for just a particular connection
of device 192.168.250.1.

Double-click device 192.168.250.1 in the Network Configuration WIndow.

44

Checking Bandwidth Usage and Adjusting the Packet Interval (RPI) Section 2-3

Information about the connection with device 192.168.250.20 is registered in
