Chapter 1
Installation and Wiring
Introduction This chapter tells you how to successfully install the Bulletin 193
EtherNet/IP™ Communication Auxiliary Module and properly connect it to
an EtherNet/IP and DeviceNet™ network.
Overview The Bulletin 193 EtherNet/IP Communication Auxiliary Module is an
EtherNet/IP to DeviceNet linking device. It provides a means for devices that
primarily communicate on a DeviceNet network (for example, a Bulletin 193
or 592 E3 Plus™ Overload Relay or a Bulletin 825-P Electronic Overload Relay)
to communicate to EtherNet/IP-based scanners. The EtherNet/IP
Communication Auxiliary Module allows up to six DeviceNet-based devices
to be scanned via Implicit Messaging and can bridge Explicit Messaging for all
nodes on a DeviceNet network. The EtherNet/IP Communication Auxiliary
Module 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
Communication Auxiliary Module from its power source before installing or
servicing. Install in suitable enclosure. Keep free from contaminants.
ATTENTION: The EtherNet/IP Communication Auxiliary Module contains ESD
(electrostatic discharge) sensitive parts and assemblies. Static control
precautions are required when you install, test, service, or repair the EtherNet/IP
Communication Auxiliary Module. Component damage can result if you do not
follow ESD control procedures. If you are not familiar with static control
procedures, See 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 take precedence. Rockwell Automation cannot assume
responsibility for the compliance or proper installation of the EtherNet/IP
Communication Auxiliary Module or associated equipment. A hazard of
personal injury and/or equipment damage exists if codes are ignored during
installation.

12 Rockwell Automation Publication 193-UM014C-EN-P - August 2016
Chapter 1 Installation and Wiring
ATTENTION: An incorrectly applied or installed EtherNet/IP Communication
Auxiliary Module can result in damage to the components or reduction in
product life. Wiring or application errors (for example, supplying incorrect or
inadequate supply voltage or operating/storing in excessive ambient
temperatures) can result in malfunction of the product.
ATTENTION: Only personnel familiar with the EtherNet/IP Communication
Auxiliary Module 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
can cause radio interference, in which case you 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.

Network Design The EtherNet/IP Communication Auxiliary Module is available as a single
Ethernet port (Cat. No. 193-DNENCAT) and dual Ethernet port (Cat. No.
193-DNENCATR) module that has RJ45 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.
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.
See http://ab.rockwellautomation.com/Networks-and-Communications/
Ethernet-IP-Network for more information.
The Cat. No. 193-DNENCATR Module 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 17.

Chapter 2
Configure the EtherNet/IP Communication
Auxiliary Module
Introduction This chapter describes how to configure an EtherNet/IP communication
auxiliary module to operate on an EtherNet/IP network.
When you first install an EtherNet/IP communication auxiliary module, the
module is Dynamic Host Configuration Protocol (DHCP) enabled.
Determining Network
Parameters
To operate an EtherNet/IP network, you must define these parameters.
Table 2 - EtherNet/IP Network Parameters
If DNS addressing is used or if the module is referenced via a host name in an
MSG instruction, you must define the following parameters. Consult with
your Ethernet network administrator to determine whether these parameters
need to be specified.
Network Parameter Description
IP Address
The IP address uniquely identifies the module. The IP address is in the
form xxx.xxx.xxx.xxx where each xxx is a number from 0...255. Do not use
the following IP addresses, because these are reserved values:
• 0.0.0.1...0.255.255.255
• 127.0.0.0...127.255.255.255
• 224.255.255.255...255.255.255.255
Subnet Mask
Subnet addressing is an extension of the IP address scheme that allows a
site to use a single network ID for multiple physical networks. Routing
outside of the site continues by dividing the IP address into a net ID and a
host ID via the class. Inside a site, the subnet mask is used to redivide the
IP address into a custom network ID portion and host ID portion.
NOTE: If you change the subnet mask of an already-configured module,
you must cycle power to the module for the change to take effect.
Gateway
A gateway connects individual physical networks into a system of
networks. When a node needs to communicate with a node on another
network, a gateway transfers the data between the two networks.

20 Rockwell Automation Publication 193-UM014C-EN-P - August 2016
Chapter 2 Configure the EtherNet/IP Communication Auxiliary Module
Table 3 - EtherNet/IP Network Parameters for DNS Addressing
Setting the IP Network
Address
An EtherNet/IP communication auxiliary module ships with DHCP enabled.
You can set the network Internet Protocol (IP) address by using the following:
• EtherNet/IP node address selection switches
• Bootstrap Protocol (BOOTP)/Dynamic Host Configuration Protocol
(DHCP) server
For example, use the Rockwell Automation BOOTP-DHCP Server
Utility, which is included with Rockwell Software’s RSLinx™ Classic
software.
• Web browser and MAC scanner software
EtherNet/IP Node Address Selection Switches
The EtherNet/IP communication auxiliary module comes with three node
address selection switches that allow you to select the last octet for the IP
address 192.168.1.xxx.
Network Parameter Description
Host Name A host name is part of a text address that identifies the module. The full
text address of a module is: host_name.domain_name.
Domain Name
A domain name is part of a text address that identifies the domain in
which the module resides. The full text address of a module is:
host_name.domain_name. The domain name has a 48-character limit.
Primary DNS Server Address This identifies any DNS servers used in the network. You must have a DNS
server configured if you specify an SMTP server with a name. The DNS
server converts the domain name or host name to an IP address that can
be used by the network.
