About This User Manual
General
This user manual provides application notes and procedures for the wiring and
installation of DeviceNet networks. It is intended for instrument engineers,
technicians, electricians, and installation personnel for the wiring and associated
components of DeviceNet applications.
The main topics covered in this user manual are:
• DeviceNet topology.
• Transmission technologies.
• Cable media and DeviceNet components.
• Plant design and cable laying regulations.
How to Use this User Manual
Section 1, Introduction gives a brief overview of the DeviceNet protocol, technical
terms, and transmission technologies.
Any security measures described in this document, for example, for user access,
password security, network security, firewalls, virus protection, etc., represent
possible steps that a user of an 800xA System may want to consider based on a
risk assessment for a particular application and installation. This risk assessment,
as well as the proper implementation, configuration, installation, operation,
administration, and maintenance of all relevant security related equipment,
software, and procedures, are the responsibility of the user of the 800xA System.

Section 2, Transmission Media and Components provides detailed information
about the DeviceNet characteristics such as topology, network limits, bus line
length, power supply considerations, basics of cable types, and network
components. This section also provides the basics of DeviceNet technology.
Section 3, Installation describes DeviceNet topologies that are used with certain
transmission media and components described in Section 2. This section provides
the guidance to install the power supply units and the DeviceNet network.

Warning, Caution, Information, and Tip Icons
This publication includes Warning, Caution, and Information where appropriate
to point out safety related or other important information. It also includes Tip to
point out useful hints to the reader. The corresponding symbols should be
interpreted as follows:
Electrical warning icon indicates the presence of a hazard which could result in
electrical shock.
Warning icon indicates the presence of a hazard which could result in personal
injury.
Caution icon indicates important information or warning related to the concept
discussed in the text. It might indicate the presence of a hazard which could
result in corruption of software or damage to equipment/property.
Information icon alerts the reader to pertinent facts and conditions.

About This User Manual Terminology
9ARD000015-600 9
Although Warning hazards are related to personal injury, and Caution hazards are
associated with equipment or property damage, it should be understood that
operation of damaged equipment could, under certain operational conditions, result
in degraded process performance leading to personal injury or death. Therefore,
fully comply with all Warning and Caution notices.
Terminology
A complete and comprehensive list of Terms is included in the IndustrialIT
Extended Automation System 800xA, Engineering Concepts instruction
(3BDS100972*). The listing included in Engineering Concepts includes terms and
definitions as they apply to the 800xA system where the usage is different from
commonly accepted industry standard definitions and definitions given in standard
dictionaries such as Webster’s Dictionary of Computer Terms.
Tip icon indicates advice on, for example, how to design your project or how to
use a certain function
Term/Acronym Description
AC 800M ABB Controller 800M series, general purpose process
controller series by ABB.
CIP Common Industrial Protocol.
Connector A coupling device used to connect the wire medium to a
Fieldbus device or to another segment of wire.
Device Tap A junction box that allows multiple drop lines to connect
to the trunk line.
DeviceNet The DeviceNet network is an open device level network
that provides connections between simple industrial
devices (such as sensors and actuators) and
higher-level devices (such as programmable controllers
and computers).
Drop Line The drop line is made up of thick or thin cable. It
connects taps to nodes on the network.

Terminology About This User Manual
10 9ARD000015-600
EMC The ability of a product to operate within its intended
electromagnetic environment and to accept or emit RF
disturbances within defined limits.
EtherNet/IP The EtherNet/IP network offers a full suite of control,
configuration, and data collection services by layering
the Common Industrial Protocol over the standard
protocols used by the Internet (TCP/IP and UDP).
EtherNet/IP uses TCP/IP for general
messaging/information exchange services and UDP/IP
for I/O messaging services for control applications. This
combination of well-accepted standards provides the
functionality required to support both information data
exchange as well as control applications.
MAC ID The Media Access Controller Identifier (MAC ID) is an
identification value assigned to each node on the
DeviceNet Network. This value distinguishes a node with
all other nodes on the same link.
Node/Device A connection to a link that requires a unique MAC ID.
Power Tap The physical connection between the power supply and
the trunk line.
Terminating Resistor The resistor (121 ohm, 1% Metal Film, 0.25 W or larger)
connected at both the ends of a trunk line.
Trunk Cable The cable path between terminators that represents the
network backbone. It can be made of thick, thin, or flat
cable and connects to taps or directly to the device.
