Rockwell Automation offers you a choice of networks and a
broad scope of products to fit your unique application through
its NetLinx Open Architecture. The NetLinx Open
Architecture is a combination of network services with a
common wire-independent protocol and open software
interfaces to help ensure the efficient flow of your information
and control data up and down your organization
seamlessly.The NetLinx Open Architecture is conceptual and
is used to describe these open networks:

• DeviceNet
• ControlNet
• EtherNet/IP

The NetLinx architecture, a combination of wire-independent
networks with open software interfaces, helps ensure the
efficient flow of your control data and information. The
NetLinx architecture is designed to include overlapping
device, control, and information networks and bring you a
more efficient way to combine these networks without
sacrificing performance. Based on your application, you can
mix any of the three networks without extra programming or
routing tables.

Open indicates that the specifications and technology are
not managed or governed by Rockwell Automation.

Control and Information Protocol (CIP) is a major component
within the NetLinx open network architecture, and it provides
you with four common features:

• common control services – provide you with a standard

set of messaging services for all three networks within the
NetLinx architecture

• common communication services – let you connect to any

network and configure and collect data from any network

• common routing capabilities – save time and effort during

system configuration because no routing tables or added
logic are necessary to move data between networks

• common base knowledge – reduces the amount of

training needed when moving to different networks within
the NetLinx architecture by providing similar configuration
tools and features

With the NetLinx open network architecture you can:

• Control. Provides real-time data exchange in a variety of

methods: selectable I/O refresh rates, single producer or
multi-producer systems, shared inputs, peer-to-peer
messaging, and interlocking between controllers.

• Configure. Able to configure all network devices from any

network location. You can configure devices upon
start-up, modify device parameters with a click of a mouse
or through controller logic without having any impact on
control performance. You no longer have to move from
network to network for configuration purposes. Now, you
can set-up your entire system from one location with one
connection.

• Collect. Provides a perfect solution for HMI display,

trending and analysis, recipe management or for
maintenance and troubleshooting. This can be done at
regular intervals or on-the-fly.

The NetLinx open network architecture is efficient because of
its producer/consumer networking services and standard
hardware and software interfaces. On producer/consumer
networks, if a node needs the packet, it will consume the
packet. So the producer sends that packet once, and all the
nodes consume the same packet if they need it. This
breakthrough brings you:

• increased efficiency because data is produced once,

regardless of the number of consumers

• precise synchronization because data arrives at each

node at the same time

Overview of Allen-Bradley Communication Networks

Allen-Bradley Open Communication Networks Operate with Devices Manufactured by Various Vendors
and Share Data with Industry-standard Information Networks

The Allen-Bradley open communication architecture offers
seamless connectivity between plant-floor devices, peer
control devices, and business computing systems. Our
architecture includes three levels of networks:

• the control and information network, (EtherNet/IP) is an

open industrial networking standard that supports implicit
messaging, explicit messaging or both and uses
commercial off-the-shelf Ethernet communication chips
and physical media.

• the control and automation network, (ControlNet) which

allows intelligent automation high-speed control devices to
share the information required for supervisory control,
work-cell coordination, operator interface, remote device
configuration, programming, and troubleshooting

• the device network, (DeviceNet) which offers high-speed

access to plant-floor data from a broad range of plant-floor
devices and a significant reduction in wiring

EtherNet/IP, ControlNet, and DeviceNet are open networks.
With our open architecture you’re not restricted to buying
only A-B devices if you implement an A-B network.

Rockwell Automation developed the ControlNet and
DeviceNet baseline specifications and made them available
to independent organizations who took ownership of the
specifications. For example, the Open DeviceNet Vendors
Association (ODVA) was formed to take ownership of the
specification and support worldwide growth of DeviceNet.
To date, more than 400 companies are supporting
DeviceNet, ControlNet, and EtherNet/IP products.
EtherNet/IP is managed by ControlNet International and
ODVA.

Our open communication architecture lets you bring
plant-floor data from low-level devices to personal computers
and mainframes that run on multiple operating systems.

This table helps you determine which Allen-Bradley networks
provide the best solution for your application needs. The
product pages referenced in the table provide more detailed
information on each network, and are followed by selection
charts describing communication interfaces for that network.

DeviceNet Network

Advantages

The DeviceNet

 network is a low-level network that provides

connections between simple industrial devices (such as
sensors and actuators) and higher-level devices (such as
PLC controllers and computers). The DeviceNet network is a
flexible, open network that works with devices from multiple
vendors.

The DeviceNet network:

• Provides a cost-effective networking solution to simple

devices

• Lets you access data in intelligent sensors/actuators from

multiple vendors

• Provides master/slave and peer-to-peer capabilities
• Producer / Consumer services let you configure devices,

control, and collect information over a single network

Functional Design

The DeviceNet network provides more than just a protocol
specification. It provides interoperability through
standardized:

- open- and sealed-type device connectors

- diagnostic indicators (LEDs)

- device profiles

In addition to reading the state of on/off sensors and
operating motor starters, the DeviceNet network can report
temperatures and the load current in the motor starter,
change the deceleration rate of drives, adjust the sensitivity
of sensors, and more.

Devices may be removed and replaced without shutting
down other devices and without programming tools, which
helps lower maintenance costs.

Networked device installation is more cost-effective than
traditional I/O wiring in many applications, particularly when
devices are spread over several hundred feet.

Mechanical Design

For information about DeviceNet Physical Media (a
combination of taps and shielded, twisted-pair media for
device connection), see page 18-11. For information about
the DeviceNet KwikLink Connection System (a system
comprised of flat four-wire cable and insulation displacement
connectors), see page 18-12.

Communication

The DeviceNet network is based on proven, well-known CAN
technology, which helps to ensure both end user and
industry-wide understanding and acceptance.

An open device network standard helps to improve overall
productivity by giving end users more choices and
encouraging device innovations that can improve accuracy,
provide diagnostics, and increase the amount of process
data.

Messages from a node on either a ControlNet link, a DH+
link, or an Ethernet link can be routed thru the ControlLogix
gateway to a node on a DeviceNet link.

Features

• Interchangeability. Simple devices (e.g., push buttons,

motor starters, photo cells, limit switches, etc.) from
multiple vendors that comply with DeviceNet network and
device profile standards are interchangeable, giving users
flexibility and choices

• One common network. An open device network standard

provides common end-user solutions, reducing the need
for vendors to support a variety of the device networks on
the market

• Reduce downtime. Diagnostics provide predictive failure

warnings and troubleshooting

Typical Applications

The DeviceNet network is ideal for applications requiring:

• Wire reduction
• Quick installations and start-ups
• Flexibility to add or move devices and cable segments
• Fast response time
• Diagnostics from devices for critical uptime requirement

The DeviceNet network is an open communication network
designed to connect plant-floor devices to control systems
without interfacing them through an I/O system. It increases
the amount and rate of information from plant-floor devices,
and has the potential to substantially reduce wiring costs.

You can connect 64 logical nodes (2,048 devices) to one
DeviceNet network. The ability to remove and replace
networked devices while under power — and without a
programming tool — is a distinct advantage of the DeviceNet
network. The DeviceNet network uses a combination of taps
and shielded, twisted-pair media for device connection.

DevicePort taps are passive, multi-port taps that connect to
the DeviceNet network via a drop line. DevicePort taps are
offered with 4 or 8 micro quick-disconnect ports in sealed
versions to connect up to 8 physical devices. Using the
DevicePort tap reduces the number of physical taps on the
DeviceNet trunk line from as many as eight taps to just one.

DeviceBox taps are passive, sealed junction boxes with 2, 4,
and 8 ports. They connect directly to the DeviceNet trunk
line, providing terminal strip connections for 8 logical nodes
(devices).

Allen-Bradley offers a complete line of physical media
products (1485 series), including trunk line, drop line,
terminators, quick-disconnect cord sets, and taps, for your
DeviceNet connection and communication needs.

typical configuration drawing, see page 18-12.

Terms and Definitions (DeviceNet Physical Media)

DeviceBox tap: A junction box that allows two, four, or eight
drop lines to be connected to the trunk line.

DeviceLink

 cable: A single active node or interface along

the DeviceNet network that allows virtually any 24V dc
sensing device to be connected to the network.

DeviceNet

 network: A low-level I/O network that provides

low-cost, medium-speed connections between low-level
industrial devices and higher-level control devices.

DevicePort tap: A junction box with sealed connectors that
allows four or eight drop lines to be connected to the trunk
line.

DeviceTap

 tap: Point of attachment from DeviceNet nodes

to the trunk or drop line. A tap lets you easily remove a node
without disrupting the network.

Drop Line (thin): The cable path that connects taps to
nodes on the network. The drop line is usually thin cable, but
thick cable can also be used.

Node or device: An addressable device that contains the
DeviceNet communication circuitry.

Open connector: Type of connector used with devices not
exposed to harsh environments.

Open-style tap: Screw terminals that connect a drop line to
the trunk line.

Power regulator: A component on each device that converts
power on the DeviceNet network to the level required locally.

PowerTap tap: Point of attachment from the power supply to
the trunk line. A PowerTap tap differs from a DeviceTap tap
in that it contains two fuses and a Schottky Diode.

Sealed connector: Type of connector used with devices
exposed to harsh environments.

T-Port tap: A single-port connection with sealed connectors.

Terminating resistor: The resistor (121

W, 1%, ¼W or larger)

attached to the ends of the trunk line.

Trunk Line (thick): The cable path between terminators that
serves as the backbone of the DeviceNet network. The trunk
line connects to taps or directly to devices. It is usually made
of thick cable, but thin cable can also be used in specified
lengths (consult the ODVA DeviceNet Specifications for
guidelines).

DeviceNet KwikLink Connection System

Advantages

The KwikLink

 connection system provides the simplest,

most modular implementation of a DeviceNet system using
flat four-wire cable and IDCs (insulation displacement
connectors). This system is designed to promote 50 percent
savings in installation costs and a drastic reduction in labor
and materials. The KwikLink system lets you add/remove
nodes from the DeviceNet network quickly and easily without
severing the trunkline. The cable is physically keyed to
prevent wiring mistakes. KwikLink offers simplicity while still
supporting 64 nodes at all three transmission rates: 125, 250,
and 500k bit/s. ArmorBlock MaXum

 I/O is compatible with

the KwikLink connection system.

Functional and Mechanical Design

All three variations of KwikLink cable are unshielded and
contain four conductors. Sharing a common profile, all three
cables are also conveniently sized for placement in 1-inch
conduit. With a wide operating temperature range and
rugged jacket materials, KwikLink flat cable was designed
with rough industrial conditions and outdoor use in mind.

• Class 1 (CL1 Cable)

Per NEC specifications for a Class 1 circuit, the power
source must have a rated output of less than 30V and
1000VA. Based on the size of the flat cable conductors,
the maximum current through the network must be no
more than 8A. For applications requiring 8A in the field, a
Class 1 rated flat cable is available.

Allen-Bradley Class 1 KwikLink cable is UL listed for 600V
and 8A at 24V dc. For optimal chemical resilience and
superior protection in harsh environments, KwikLink Class
1 cable also features a Thermoplastic Elastomer (TPE)
jacket providing maximum toughness with excellent
flexibility.

• Class 2 (CL2) Cable

For less demanding applications at lower currents,
Allen-Bradley offers a PVC-jacketed Class 2 cable. More
flexible than the CL1 cable, this design adheres to NEC
Article 725, which states that for a Class 2 circuit, the
power source must have a rated output of less than 30V
and 100VA. In the case of DeviceNet communication,
running at 24V, the maximum allowable current is then
100VA/24V or 4A. Therefore, KwikLink CL2 cable is rated
to 4A at 24V dc.

• Auxiliary Power Cable (CL1)

In some cases, it may be desirable to run an auxiliary bus
to power outputs, i.e. valves, actuators, indicators. To
support such an application, Allen-Bradley provides a
black PVC power cable for use with KwikLink connectors.
KwikLink power cable is Class 1 cable capable of
supplying 24V of output power with currents up to 8A.

Terms and Definitions

Please familiarize yourself with these terms and definitions
as they do appear in the catalog pages that follow.

NetLinx communication technologies help you configure,
collect, and / or control information more efficiently by
providing reduced control programming, increased system
performance, reduced number of networks, and greater
flexibility.

You have the option of implementing all of the NetLinx
services into your products. NetLinx technologies consist of
networks as well as software and hardware interfaces as
shown below:

• Networks. Producer / Consumer services found in

DeviceNet, ControlNet, Ethernet, and FOUNDATION
Fieldbus H1 networks.

• Interfaces. PCI and PCMCIA cards; bridges and

gateways such as ControlLogix Gateway, RSLinx
Gateway and standalone linking devices; software drivers
such as RSLinx software; APIs such as OPC and DDE;
and enabler technologies that are embedded in
networked devices such as daughtercards, stacks,
sample code, etc.

IOLinx

t is a family of Rockwell Automation Allen-Bradley

I/O software drivers and application programming interface
(API) that provide software developers a standardized way to
link their applications to real-time, open-platform I/O scanning
hardware (compatible with Windows 95 and Windows NT
operating systems).

RSLinx is a 32-bit product family (compatible with Windows
95 and Windows NT operating systems) that supports
Rockwell Software and Allen-Bradley programming, HMI, and
component software products. It serves plant-floor data to
commercially available DDE client applications such as
Microsoft Excel and Access.

PCI means peripheral component interconnect. An example
of a Rockwell Automation PCI card is 1784-PCID.

Compact PCI is the newest standard for industrial PCs. It’s
a rack-mountable open-bus interface card. An example of a
Rockwell Automation PCI card is 1784-CPCIDS.

PCMCIA (Personal Computer Memory Card International
Association) developed a standard for credit-card size
personal computer (PC) cards.

PC cards developed under release 1.0 of the PCMCIA
standard are used for data storage. PC cards developed
under release 2.0 of the PCMCIA standard, such as the
1784-PCD, can be used for both I/O and data storage.

PC cards were developed because personal computers
have become smaller, and, as a result, there’s a need for
smaller storage media. The PC card is a small form-factor
adapter that can add memory, storage, and I/O capabilities to
small computers.

All PC cards measure the same length and width 54

85.6

mm (2.13

3.37 in), but they have different thicknesses in

the center. The thickness at the connector end and along
the rails is the same for all types of PC cards. Currently, there
are three types of PC cards.

• Type I measures 3.3 mm (.13 in) thick. Used for data

storage such as Flash memory cards

• Type II measures 5.0 mm (.2 in) thick. Used for I/O such

as modem, LAN, and host communication

• Type III measures 10.5 mm (.4 in) thick. Used for data

storage or I/O capabilities that require more space such
as rotating media and wireless communication devices

ControlNet Network

Advantages

The Allen-Bradley ControlNet network is a state-of-the-art
control network that meets the demands of real-time, high-
throughput applications. The ControlNet network combines
the functionality of an I/O network and a peer-to-peer network
while providing high-speed performance for both functions.

The ControlNet network gives you deterministic, repeatable
transfers of all mission-critical control data in addition to
supporting transfers of non-time-critical data. The patented
media-access method used on the ControlNet network
results in deterministic delivery of time-critical (scheduled)
data by assigning it a higher priority than non-time-critical
(unscheduled) data. As a result, I/O updates and
controller-to-controller interlocking always take precedence
over program uploads and downloads and messaging.

The ControlNet network and products such as the
ControlNet-to-DeviceNet Linking Device (catalog number
1788-CN2DN), help deliver solutions that integrate
FOUNDATION Fieldbus devices and DeviceNet devices into
a common, seamless architecture.

All devices on the ControlNet network have direct access to
all data on FOUNDATION Fieldbus network. The
ControlNet-to-FOUNDATION Fieldbus (H1) Linking Device
(catalog number 1788-CN2FF) has many benefits:

• configuration of FOUNDATION Fieldbus devices from the

ControlNet network

• two-way data sharing between ControlNet devices and

FOUNDATION Fieldbus devices

• diagnostic feedback and monitoring of multiple

FOUNDATION networks from a single ControlNet network

• centralized controllers on a ControlNet network control

events on FOUNDATION Fieldbus networks

Flexible installation options for the ControlNet network
include:

• Redundant Media Option helps ensure that a system can

maintain operation during a cable fault condition

• Intrinsic Safety Option lets you install a ControlNet

network in hazardous, explosive locations. The
combination of a ControlNet 1786 fiber hub and a
ControlNet Ex 1797 fiber hub allows for flawless

high-speed deterministic data flow and messaging
between hazardous and safe areas. This combination
functions as an intrinsically-safe isolator between
hazardous and safe areas and can provide long-distance
communication.

Functional Design

The ControlNet network is simple and cost-effective to install,
and offers you flexible installation options. A-B offers PLC
processors with built-in ControlNet scanners, ControlNet
adapters for I/O chassis, and ControlNet computer interfaces
for personal computers. Although the ControlNet network is
based on bus technology, you can use repeaters to
implement tree and star topologies. You can also install
optional redundant media. The ControlNet processors
include ports that let you share data between a ControlNet
network and your already installed Data Highway Plus and
Universal Remote I/O networks.

include: controllers, I/O, MMIs, PCs, drives, coordinated drive
systems, weld control, motion control, vision systems,
transducers, and valve manifolds.

Mechanical Design

The ControlNet network transfers scheduled data at 5M bit/s,
which improves both I/O performance and processor-to-
processor communication. Its flexible control system
architecture can work with multiple processors, and you can
install up to 99 addressable nodes (via taps) anywhere along
the trunk cable of a ControlNet link. There is no minimum tap
separation, and you can access the ControlNet network from
every node (including adapters).

Communication

The ControlNet network provides the functions of the A-B
Data Highway Plus and Universal Remote I/O networks at a
5M-bit/s rate. Multiple processors can each control their own
assigned outputs on a single common ControlNet link and to
each monitor all inputs on the link. Any processor on the link
can send a message to any other processor on the link.

Messages from a node on one ControlNet link can be routed
through the ControlLogix gateway to a node on either
another ControlNet link, a DeviceNet link, a DH+ link, or an
Ethernet link.

ControlNet I/O

In addition to accommodating the high ControlNet data
transfer rate and a large number of I/O chassis, the
ControlNet link provides a simple, deterministic, flexible
means of transferring I/O data.

For I/O on a ControlNet link, you can implement both discrete
and non-discrete transfers of I/O data:

• A discrete transfer of I/O data occurs when a single unit of

I/O data (8, 16, or 32 bits that correspond to the module’s
I/O image) is transmitted to or received from each I/O
module in the I/O chassis. With just one discrete transfer,
you can update the I/O image for all of the modules in the
I/O chassis.

ControlNet I/O is continued along with Features, and Typical
Applications on page 18-19.

18-19

Communication

ControlNet Network

• A non-discrete transfer of I/O data occurs when a block of

data (64 words maximum in a single packet) is transferred
to or from an I/O module.

Each ControlNet processor’s I/O map table can contain a
limited number of entries. Each entry corresponds to one
scheduled transfer of I/O data between the ControlNet
processor and an I/O chassis or I/O module, or of a message
to another ControlNet processor.

Since making an I/O map table entry schedules transfers of
I/O data on the periodic basis that you specify, for these
scheduled transfers of I/O data you do not program them into
ladder logic. For non-discrete transfers of I/O data, you have
the option of programming them as non-scheduled transfers
to make them event-driven transfers.

Although a ControlNet link can have 99 nodes, the number of
I/O chassis/adapters it can support may be limited by the
maximum number of entries in each processor’s I/O map
table. If each map table entry schedules a discrete transfer
of data, the number of I/O chassis you could have on the
ControlNet link is equal to the number of entries allowed in
the I/O map table if that number is less than 98.

Since you are limited by the number of entries in the
processor’s I/O map table, each entry that schedules a
non-discrete transfer of I/O data must be subtracted from the
maximum number of I/O chassis/adapters. For example, if
you have 20 entries in the I/O map table for non-discrete
transfers of I/O data, you reduce the number of possible I/O
adapters on a PLC-5/40C ControlNet link by 20 (from the
maximum of 96, down to 76 adapters).

In addition to I/O map table entries for scheduled transfers of
data, the ControlNet network uses unscheduled transfers of
data to communicate with programming terminals, operator
interfaces, and other devices;

see page 18-20.

routed through the ControlLogix gateway to/from a node
on either another ControlNet link, a DH+ link, or an
Ethernet link

Typical Applications

The ControlNet network is well-suited to applications that
include high-speed digital I/O and/or remote analog I/O, such
as:

• Automotive transfer lines, paint shops, and assembly lines
• Water/wastewater
• Food processing
• Pharmaceutical
• Test stands
• Sectional conveyors
• Discrete-part machines
• Filter presses
• Baggage handling
• Most other high-speed applications that require highly

synchronized control, high throughput and speed, high I/O
count, distribution across large geographic distances,
real-time performance

EtherNet/IP Network

Advantages

Ethernet Industrial Protocol (EtherNet/IP) is an open
industrial networking standard that supports implicit
messaging (real-time I/O messaging), explicit messaging
(message exchange), or both and uses commercial
off-the-shelf Ethernet communication chips and physical
media. Because Ethernet technology has been used since
the mid 1970s and is widely accepted throughout the world,
Ethernet products serve a large community of vendors. By
using Ethernet products, not only are you following the
common trend in technology today but you have the ability to
access device-level data all the way from the Internet.
EtherNet/IP emerged due to the high demand for using the
Ethernet network for control applications.

EtherNet/IP is an open network because it uses:

• IEEE 802.3 Physical and Data Link standard
• Ethernet TCP/IP protocol suite (Transmission Control

Protocol/Internet Protocol), the Ethernet industry standard.

• Control and Information Protocol (CIP), the protocol that

provides real-time I/O messaging and information /
peer-to-peer messaging. ControlNet and DeviceNet
networks also use CIP.

TCP/IP is the transport and network layer protocol of the
Internet and is commonly linked with Ethernet installations
and the business world. TCP/IP provides a set of services
that any two devices can use to share data. Because
Ethernet technology and standard protocol suites such as
TCP/IP have been published for public use, standardized
software tools and physical media have been
mass-produced and are readily available offering you two
benefits:

• known technology
• accessibility

The UDP/IP (User Datagram Protocol) is also used in
conjunction with the Ethernet network. UDP/IP provides the
fast, efficient data transport necessary for real-time data
exchange.

To make EtherNet/IP successful, CIP has been added on top
of TCP/UDP/IP to provide a common application layer.
Therefore, when you choose an EtherNet/IP product, you are
choosing a product with CIP capabilities. Additionally,
EtherNet/IP uses the producer/consumer network model, as
do DeviceNet and ControlNet networks. With the introduction
of Ethernet switch technology and full-duplex data
transmission, the occurrence of data collisions is theoretically
eliminated, and performance is drastically enhanced on your
EtherNet/IP network.

Functional Design

Typical devices communicating across an EtherNet/IP
network include:

• mainframe computers
• PLC processors
• robots
• HMI
• I/O and I/O adapters

Target applications include:

• plant management system tie-in, material handling
• configuration, data collection, and control on a single

high-speed network

• time-critical applications with no established schedule

Mechanical Design

Typically an EtherNet/IP network uses an active star topology
in which groups of devices are connected point-to-point to a
switch as shown in the typical configuration drawing

(page

18-30)

. The benefit of a star topology is in its support of both

10 and 100M bit/s products. You can mix 10 and 100M bit/s
products, and most Ethernet switches will negotiate the
speed. The star topology offers you connections that are
simple to wire, easy to debug and detect failures, and easy to
maintain.

EtherNet/IP is designed to handle large amounts of
messaging data, 1500 bytes maximum per packet. In
addition to handling large amounts of data, the EtherNet/IP
speed (10/100M bit/s) makes that data transmission even
more appealing. Because of the wide acceptance of Ethernet
technology throughout the years, the cost per node for
Ethernet switches and other Ethernet physical media is
rapidly decreasing. With these characteristics, EtherNet/IP is
becoming a viable choice for many control applications.

The EtherNet/IP cabling components provide flexibility in two
areas: overall cost and manufacturer. Due to the large
number of third-party vendors, you now have a wide
selection of media components and cost considerations.
When building your network, you may use many of the
following components: cabling, transceivers, hubs, repeaters,
routers, and switches.

Standard twisted-pair and fiber-optic cable are fully functional
with EtherNet/IP. Depending on your environment, you might
consider products that have been tested and proven for
industrial applications (refer to the Ethernet Media Installation
Guide, publication ENET-1N001A-EN-P). Depending upon
your network configuration, you may need an Ethernet hub or
switch. A hub is an inexpensive connectivity method that
provides an easy method of connecting devices on
information networks. A switch reduces collisions and is
recommended for real-time control installations. Routers are
used to isolate control data traffic from other types of office
data traffic, to isolate information traffic on the plant floor from
control traffic on the plant floor, and for security purposes,
i.e., firewalls. Repeaters extend your overall network cable
length. They can also connect networks with different media
types.

Communication

EtherNet/IP Network

Communication

Ethernet TCP/IP connectivity was originally added to the
Ethernet PLC and SLC products using the Allen-Bradley
Client Server Protocol (CSP), a master/slave protocol that is
capable of explicit messaging and program uploads and
downloads. But as stated earlier

(page 18-3)

, the new

Rockwell Automation communication protocol is called the
Control and Information Protocol (CIP), which was introduced
in 1999 for interoperability. All our EtherNet/IP products in the
ControlLogix, PLC-5, and SLC families use CIP to
communicate.

For more information, refer to the EtherNet/IP

Products Guide table on page 18-28.

EtherNet/IP Transmission Types

The control portion of CIP is used for real-time I/O messaging
or implicit messaging. The information portion of CIP is used
for message exchange or explicit messaging. Use these
three definitions to help explain the transmission types used
in the table below.

• Information. Non-time critical data transfers — typically

large packet size. Information data exchanges are
short-lived explicit connections between one originator
and one target device. Information data packets use the
TCP/IP protocol and take advantage of the TCP data
handling features.

• I/O Data. Time-critical data transfers — typically smaller

packet size. I/O data exchanges are long-term implicit
connections between one originator and any number of
target devices. I/O data packets use the UDP/IP
protocols and take advantage of high-speed throughput
capability of UDP.

• Real-time Interlocking. Cyclic data synchronization

between one producer processor and any number of
consumer processors. Interlocking data packets use the
faster UDP/IP protocols and take advantage of
high-speed throughput capability of UDP.

Explorer or Netscape. Refer to the EtherNet/IP Products
Guide for a list of our products that have HTTP capability,

page 18-28.

Among our EtherNet/IP products various

features are available such as:

• read / write data
• read diagnostics
• send e-mail
• edit configuration data

Ethernet I/O

We now offer products that have Ethernet ports for scanning
functionality and products that have Ethernet ports for
adapter functionality to control I/O over an EtherNet/IP
network. Using either a ControlLogix 10M bit Module (catalog
number 1756-ENET series B) or a ControlLogix 10/100M bit
Module (catalog number 1756-ENBT), you have a local
bridge to a ControlLogix processor for scanning as well as a
remote ControlLogix I/O adapter. This module supports the
transfer of real-time I/O data, processor-to-processor
interlocking, and seamless routing of messages between
EtherNet/IP, ControlNet, and DeviceNet networks. In addition
to accommodating the high data transfer rate and a large
number of I/O chassis, the EtherNet/IP network provides a
simple, flexible means of transferring 1756 I/O data. For more
information about 1756 I/O, refer to the ControlLogix / 1756
System section of this catalog.

The EtherNet/IP FLEX I/O adapter (catalog number
1794-AENT) communicates with any Logix controller on an
EtherNet/IP network. Up to eight FLEX I/O modules may be

Data Highway Plus Industrial Local Area Network

Network Description

The Data Highway Plus network is a local area network
designed to support remote programming for factory-floor
applications.

Functional Design

The Data Highway Plus network lets you connect a
maximum of 64 devices per link (although 15 or fewer nodes
are recommended per link), including:

• PLC-5 and SLC 5/04 programmable controllers
• Color graphics systems
• Personal computers
• Host computers
• Numerical controls
• Programmable RS-232-C/RS-422 devices

Mechanical Design

You can configure a network of 99 links. With a multi-link
network, you can have more nodes in the network. By
placing nodes in the proper link with some nodes and
separate from other nodes, you can also improve the
efficiency of message delivery.

Communication

With Rockwell Software Programming Software, you can
program your PLC controllers over your Data Highway Plus
network. You can program a PLC controller from its local
DH+ link or from a remote DH+ link in the network. This
means that a single industrial terminal connected to your
network can be used to program all the PLC controllers on all
links of your network.

The ControlLogix Communication Interface Module (catalog
number 1756-DHRIO) interfaces two DH+ links to the
ControlLogix backplane to provide routing of messages
between a DH+ link and:

• ControlNet links
• Ethernet Links
• DeviceNet links
• other DH+ links

For more information about 1756-DHRIO, see page 12-20.

You can also use Data Highway Plus modules to implement
a SCADA network.

Features

• Includes switches on each interface that make it easy to

reconfigure your network as it changes

• Incorporates network diagnostics that help you avoid

costly downtime and improve network efficiency

• Lets you use communication software to provide a Data

Highway Plus communication driver to various computer
platforms

Provides an interface that allows direct communication between a 16-bit ISA / EISA-bus PC and A-B Universal Remote I/O devices

18-36

Communication

Universal Remote I/O Link

Our Universal Remote I/O Link connects our SLC and PLC
processors to remote I/O chassis and a host of intelligent
devices such as operator interfaces and ac and dc drives.
I/O chassis and other devices can be mounted up to 10,000
feet from the PLC or SLC processor.

Our PLC and SLC processors access the Remote I/O Link
through built-in scanners (as in our enhanced PLC-5
processors) or through separate scanner modules (as with
our SLC processors and the 1747-SN scanner module).
I/O products communicate with these scanners over the link
through separate adapter modules (such as the 1771-ASB
adapter for the 1771 I/O chassis, 1747-ASB adapter for the
1746 I/O chassis, and 1794-ASB adapter for FLEX I/O), or
through built-in adapters (such as our 1791 I/O Blocks).

FLEX Integra I/O (1793 series) is a low-cost, small increment,
modular I/O system for distributed applications that offers all
the functions of larger I/O without the space requirements. It
combines a terminal strip and I/O interface into one small
module. FLEX Integra I/O is compatible with 1794 FLEX I/O
communication adapters. FLEX Integra I/O requires only one
1794 FLEX I/O adapter for as many as eight I/O modules.

In addition to our I/O, A-B operator interfaces, ac and dc drive
systems, intelligent sensing products, CNCs, and other
devices are compatible with this link. Some products, such
as PanelView Operator Terminals, have built in “adapter”
capability, while other products, such as our 1336 drives,
require optional “adapter” modules to put them on the link.
Some products are installed in the 1771 I/O chassis and
communicate over the chassis backplane to a Remote I/O
Adapter, which communicates to the programmable
controller’s scanner. In addition, the 1784-KTS
communication interface card lets an ISA/EISA bus PC
communicate directly with A-B remote I/O devices.

Other companies offer products such as robotic and welding
controllers, scales, and wireless modems, that are
compatible with the Universal Remote I/O Link as well. In
total, there are approximately 100 devices available that can
communicate on this link. By using these devices on the link,
you speed communication and allow the devices to work
together to help improve quality while lowering integration,
maintenance, and training costs.

For distributed processing, you can put a PLC-5 processor
in “adapter mode” and install it in an I/O chassis where it
can monitor its own resident I/O while communicating to a
supervisory PLC-5 processor over the Universal Remote I/O
Link. You can also distribute SLC processors on the link
where they can control I/O while communicating with a
supervisory processor via a 1747 Direct Communication
Module.

For high-speed processing applications, an extended-local
I/O link is available, which provides a parallel I/O link (the
practical equivalent of processor-resident-chassis
performance for I/O modules not placed in the processor’s
chassis). In addition, the A-B ControlNet network, which
gives you deterministic, repeatable transfers of control data,
is suitable for real-time, high-throughput applications.

Features

• Uses transceivers communicating over a single channel
• Uses standard PVC twinaxial cable (cat. no. 1770-CD) as

the transmission medium

• Uses a daisy-chain connection with a maximum length of

3,048m (10,000 ft)

• Operates at the data rates listed in Specifications. A

½-watt terminating resistor is required at each end of the
trunk line to eliminate reflections. Error checking is done
using standard CRC16 checks.

• Is based on the master/slave model. The programmable

controller’s scanner is the master and the I/O chassis or
adapter devices are slaves. The slave only responds
when told to by the master.

• Provides transfer of a single unit (8, 16, or 32 bits) of I/O

image data to/from each I/O module in each I/O chassis
during each I/O scan. The size of the unit depends on the
I/O addressing density selected at the I/O chassis. It can
also provide block transfers of 64 words maximum to an
individual I/O module (except when used with the
1747-SN).

• Lets Remote I/O Scanners connect to a maximum of 32

I/O chassis or other adapter-type devices on a single link.
Devices built to original Universal Remote I/O
specifications are compatible with those built to the new
specifications. However, if any of the devices on a link
are built to the original specifications, the limit is 16
devices on a single link. In any case, for a specific
scanner, the number of adapter-type devices is limited by
the I/O rack addressing capability of the scanner.

Compatibility

The strength and versatility of the Universal Remote I/O link
come from the breadth of products it supports.

In addition to 1771 I/O, the industry’s largest I/O offering, a
variety of devices can be connected to the Remote I/O Link,
as listed below. Non-Allen-Bradley devices are in italics.

Typical Applications

Typical applications range from simple I/O links with PLC
processors and I/O, to links with a variety of other A-B and
third-party devices. When drives and other devices,
including third-party devices are to be included in a
programmable controller system, the Universal Remote I/O
link provides the means to do that though remote I/O adapter
modules and built-in remote I/O adapters.

Using the Universal Remote I/O Link instead of direct wiring
a long distance to a local I/O chassis helps reduce
installation, start-up, and maintenance costs by placing the
I/O chassis closer to the sensors and actuators. To install a
Universal Remote I/O Link between buildings or in high-noise
areas, such as next to arc welders, use A-B fiber-optic
repeaters (cat. nos. 1771-AF, -AF1).

DH-485 Industrial Local Area Network

DH-485 is a local area network (LAN) designed for factory-
floor applications. DH-485 lets you connect up to 32 devices,
including SLC 500 and MicroLogix 1000 programmable
controllers, color graphics systems, and personal computers.
The DH-485 link together with auxiliary RS-232-C (DF1
protocol) links make up the DH-485 network.

With RSLinx software installed on a PC, you can
communicate with other nodes on the network.

With SLC 500 Programming Software, you can program your
SLC 500 controllers over your DH-485 network. This means
that a single PC connected to your network can be used to
program all the SLC 500 controllers on your network.

Remote Access Dial-In Kit

Remote Access lets you connect via modem to a remote
site’s network and / or programmable controller. With remote
access you can monitor the process, collect data, and make
program changes remotely for Allen-Bradley processors or
PanelView terminals.

Rockwell Automation offers Remote Access Dial-In Kits that
are designed to provide a standardized turn-key-style, dial-up
modem solution for: DH-485 networks, Data Highway Plus
networks, channel 0 of SLC, PLC-5, ControlLogix, and
MicroLogix processors.

Each Remote Access Dial-In Kit offers standard hardware
(including a DIN rail mounting kit) and required cables. In
addition, each kit provides a detailed and intuitive
CD-ROM-based tutorial, which provides “step-by-step”
installation instructions.

Features

• Each Remote Access kit contains pre-configured

industrial modems, eliminating all the guesswork from
modem setup. All modems are guaranteed to be identical

• These industrial modems support remote configuration,

so you can modify the network modem’s command
settings through a dial-up connection. This unique feature
helps you recover modem communication if a change
occurs in the SLC or PLC processor’s channel
configuration

• Remote Access modems support front-panel dialing.

Modem communication requires dedicated phone lines,
which are not cost-effective. Front-panel dialing removes
the necessity of a dedicated phone line being constantly
connected to the modem

• Remote Access modems have built-in security. Two

types of security are available: passthrough or callback,
which is authenticated with a password

• The Remote Access Tutorial provides support for an

assortment of Rockwell Software products. The tutorial
steps through software / hardware configurations under
Windows 95, Windows 98, and Windows NT v4.0
operating systems

Single-modem kits are also available, and they contain all the hardware for the

remote modem connection but not the sending modem and cables. In order to
take advantage of all the modem functionality, you must have a remote access
modem connected at both ends, so we recommend you first purchase a
two-modem kit. To order a single-modem kit, just add the number “1” to any of
the six catalog numbers above.
