Important User Information
Solid-state equipment has operational characteristics differing from those of electromechanical equipment. Safety
Guidelines for the Application, Installation and Maintenance of Solid State Controls (publication SGI-1.1 available from
your local Rockwell Automation sales office or online at http://www.rockwellautomation.com/literature/) describes some
important differences between solid-state equipment and hard-wired electromechanical devices. Because of this difference,
and also because of the wide variety of uses for solid-state equipment, all persons responsible for applying this equipment
must satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from
the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and
requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or
liability for actual use based on the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or
software described in this manual.

Installation & Wiring
Introduction
The purpose of this chapter is to provide the necessary instructions to successfully
install the EtherNet/IP™ Communications Auxilliary and properly connect it to
an EtherNet/IP and DeviceNet™ network.
Overview
The EtherNet/IP Communications Auxilliary is an EtherNet/IP to DeviceNet
linking device. It provides a means for devices that primarily communicate on a
DeviceNet™ network (e.g., an E3 Plus or 825-P Electronic Overload Relay) to
communicate to EtherNet/IP-based scanners. The EtherNet/IP
Communications Auxilliary allows up to six (6) DeviceNet-based devices to be
scanned via Implicit Messaging and can bridge explicit messaging for all nodes on
a DeviceNet network. The EtherNet/IP Communications Auxilliary uses an
internal web server to configure the module, the DeviceNet network, and
DeviceNet-based devices that fully support the Parameter Object.
SHOCK HAZARD: To prevent electrical shock, disconnect the EtherNet/
IP Communications Auxilliary from its power source before installing or
servicing. Install in suitable enclosure. Keep free from contaminants.
ATTENTION: The EtherNet/IP Communications Auxilliary contains ESD
(electrostatic discharge) sensitive parts and assemblies. Static control
precautions are required when installing, testing, servicing, or repairing
theEtherNet/IPCommuications Auxilliary.Componentdamagemay result
if ESD control procedures are not followed. If you are not familiar with
static control procedures, refer to Rockwell Automation publication 8000-
4.5.2, “Guarding Against Electrostatic Damage”, or any other applicable
ESD protection handbook.
ATTENTION: The purpose of this document is to serve as a guide for
proper installation. The National Electrical Code (NEC) and any other
governing regional or local code will take precedence. Rockwell
Automation cannot assume responsibility for the compliance or proper
installation of the EtherNet/IP Communications Auxilliary or associated
equipment.Ahazardofpersonalinjuryand/orequipmentdamageexistsif
codes are ignored during installation.

ATTENTION: An incorrectly applied or installed EtherNet/IP
Communications Auxilliary can result in damage to the components or
reduction in product life. Wiring or application errors (e.g., supplying
incorrect or inadequate supply voltage or operating/storing in excessive
ambient temperatures) may result in malfunction of the product.
ATTENTION: Only personnel familiar with the EtherNet/IP
Communications Auxilliary and associated machinery should plan to
install, set up, and maintain the system. Failure to comply may result in
personal injury and/or equipment damage.
ATTENTION: This is a Class A product. In a domestic environment, this
product may cause radio interference in which case the user may be
required to take adequate measures.
ATTENTION: To remain compliant with UL/CSA Certifications, the
DeviceNet power supply must meet NEC Class 2 Requirements.

Installation
The EtherNet/IP Communications Auxilliary may be DIN rail or panel
mounted. To avoid overheating, the unit must be mounted vertically and
requires 37.4 mm (1-1/2 in.) of clearance at the top and bottom to allow for
proper air flow. The temperature ratings for the unit will be derated if not
mounted in this manner.

Wiring
The EtherNet/IP Communications Auxilliary can accept all forms of DeviceNet
cable. However, DeviceNet shielded cable is recommended. The EtherNet/IP
Communications Auxilliary complies with the Open Device Vendors
Association (ODVA) DeviceNet compliance testing when used with 60 m or less
of trunk cable with 60 or fewer network drops.

Network Design
The EtherNet/IP Communications Auxilliary offers both a single EtherNet port
(Cat. No. 193-DNENCAT) and dual EtherNet port (Cat. No.
193-DNENCATR) module that has RJ-45 ports to connect to EtherNet cable
CAT5 type or better . Rockwell Automation offers a wide variety of Allen-
Bradley EtherNet patch cables with its Bulletin 1585 line of Ethernet cables
(http://ab.rockwellautomation.com/Connection-Devices/RJ45-Network-
Media).
Both the 193-DNENCAT and 193-DNENCATR devices support a Star
EtherNet topology in which all EtherNet nodes wire back to a central EtherNet
switch, hub, or router as shown in Figure 5 on page 8.
Figure 5 - Star EtherNet Topology
Rockwell Automation also offers a line of managed and unmanaged Allen-
Bradley EtherNet Switches with its Stratix™ family of EtherNet switches (http://
ab.rockwellautomation.com/Networks-and-Communications/Ethernet-IP-
Infrastructure/).
The 193-DNENCATR also supports a Ring EtherNet topology in which all
EtherNet nodes are wired in series with one another until a complete network
ring is made as shown in Figure 6 on page 9.

Figure 6 -Ring EtherNet Topology
The Cat. No. 193-DNENCATR supports Rockwell Automation’s Device Level
Ring (DLR) topology as a slave device in which the EtherNet/IP network will
still continue to communicate in the event that one of the network chains is
disrupted.
