Term Definition
BootP BootP (Bootstrap Protocol) is a low-level protocol that provides
configurations to other nodes on a TCP/IP network. BootP
configuration files let you automatically assign IP addresses to an
Ethernet module. You can also obtain subnet masks and gateway
addresses from BootP.
Bridge A node between two similar communication subnets where protocol
translation is minimal.
CIP Control and information protocol, the EtherNet/IP application layer
uses the producer/consumer networking model. In this model one
producer broadcasts (multicasts) the data once to all the consumers.
All consumers see the data simultaneously and may choose whether
to consume (receive) the data or not. Delivery time is consistent, no
matter how many consumers there are.
Connection The communication mechanism from the controller to another
module in the control system, usually used to exchange I/O data.
Consumer A destination device in the CIP networking model. See CIP.
Publication 1734-UM011D-EN-P - May 2011
viii Preface
Term Definition
CSMA/CD Carrier sense multiple access/collision detection is the access
method used in Ethernet. When a device wants to gain access to the
network, it checks to see if the network is quiet (senses the carrier).
If it is not, it waits a random amount of time before retrying. If the
network is quiet and two devices access the line at exactly the same
time, their signals collide. When the collision is detected, they both
back off and each waits a random amount of time before retrying.
Determinism The ability to predict when information will be delivered. Important in
time-critical applications.
DHCP The dynamic host configuration protocol is an Internet protocol,
similar to BootP, for automating the configuration of computers that
use TCP/IP. DHCP can be used to automatically assign IP addresses,
to deliver IP stack configuration parameters, such as the subnet mask
and default router, and to provide other configuration information,
such as the addresses for printer, time, and news servers.
The 1734-AENT factory default is DHCP enabled. When you apply
power, the module sends a message containing its hardware address
to any DHCP server on the network. The server(s) replies by sending a
message with an appropriate IP address for the adapter. The adapter
responds by acknowledging to a server that it will use the offered IP
address.
DNS The domain name system is a hierarchical, distributed method of
organizing the name space of the Internet. The DNS administratively
groups hosts into a hierarchy of authority that allows addressing and
other information to be widely distributed and maintained. A big
advantage to the DNS is that using it eliminates dependence on a
centrally-maintained file that maps host names to addresses.
Ethernet A physical layer standard using carrier sense multiple access with
collision detection (CSMA/CD) methods.
Publication 1734-UM011D-EN-P - May 2011
EtherNet/IP Ethernet industrial protocol applies a common application layer (CIP)
over Ethernet by encapsulating messages in TCP/UDP/IP.
Ethernet network A local area network designed for the high-speed exchange of
information between computers and related devices.
Explicit messaging Non-time critical messaging used for device configuration and data
collection, such as downloading programs or peer-to-peer messaging
between two PLC units.
Full duplex A mode of communication that allows a device to send and receive
information at the same time, effectively doubling the bandwidth.
Fully qualified
domain name
A fully qualified domain name (FQDN) is a domain name that includes
all higher level domains relevant to the entity named. If you think of
the DNS as a tree-structure with each node having its own label, a
fully qualified domain name for a specific node would be its label
followed by the labels of all the other nodes between it and the root
of the tree. For example, for a host, a FQDN would include the string
that identifies the particular host, plus all domains of which the host
is a part, up to and including the top-level domain (the root domain is
always null). For example, PARIS.NISC.SRI.COM is a fully qualified
domain name for the host at 192.33.33.109.
Gateway A module or set of modules that allows communications between
nodes on dissimilar networks.
Term Definition
Preface ix
Hardware address
Each Ethernet device has a unique hardware address (sometimes
called a MAC address) that is 48 bits. The address appears as six
digits separated by colons (such as, xx:xx:xx:xx:xx:xx). Each digit has a
value between 0 and 255 (0x00 to 0xFF). This address is assigned in
the hardware and cannot be changed. The hardware address is
required to identify the device if you are using a BOOTP utility.
Host name The host name is the unique name for a computer within its domain.
It's always the first element of a full name, and, with its domain and
top-level domain suffix, creates the unique name of that computer on
the Internet. For example, let's say a trading website is
www.trading.com. The host name is www, which is not unique on
the web, but is unique within the trading domain.
The host name can also refer to the fully qualified domain name
(FQDN), or in this example, www.trading.com. Both naming methods
seem to be used interchangeably in various documents. For the
purposes of this document, the host name will refer to the FQDN, or
as in this example, www.trading.com.
Hub A central connecting device that joins devices together in a star
configuration. Hubs are generally not suitable for use in I/O control
systems, since they are time-critical applications that cannot tolerate
lost packets.
Implicit messaging Real-time messaging of I/O data.
IP Internet protocol that provides the routing mechanism for messages.
All messages contain not only the address of the destination station,
but the address of a destination network, which allows messages to
be sent to multiple networks within an organization or around the
world.
IP address A 32-bit identification number for each node on an Internet Protocol
network. These addresses are represented as four sets of 8-bit
numbers (numbers from 0 to 255), with decimals between them. Each
node on the network must have a unique IP address.
Latency The time between initiating a request for data and the beginning of
the actual data transfer.
Multicast In the CIP producer/consumer model, one producer multicasts
(broadcasts) the data once to all the consumers.
Producer The source of information in the CIP networking model. See CIP.
Rack-optimized A physical and logical collection of application modules.
Subnet mask An extension of the IP address that allows a site to use a single net
ID for multiple networks.
Switch A network device that cross connects devices or network segments.
A switch provides each sender/receiver the full network bandwidth
(2x in full duplex mode), reduces collisions, and increases
determinism.
TCP The transport control protocol is a more reliable but slower transport
protocol than UDP. It is used for explicit (not time critical) messaging
in EtherNet/IP.

Term Definition
TCP/IP The transmission control protocol/internet protocol is a
transport-layer protocol (TCP) and a network-layer protocol (IP)
commonly used for communication within networks and across
internetworks.
Transaction An exchange of request and data and response and data
.
UDP The user datagram protocol (UDP) is a transport protocol that
provides a very simple but fast capability to send datagrams between
two devices. It is used for I/O (implicit) messaging in EtherNet/IP.

Important Adapter
Before you begin using your adapter, note the following important
considerations.
Considerations
Set the Chassis Size
The 1734-AENT POINT I/O adapter for EtherNet/IP requires
configuration of its chassis size before you can make any I/O connections.
1 Publication 1734-UM011D-EN-P - May 2011
2 About the Adapter
The default setting for the chassis size is 1 slot, which represents the adapter
by itself.
Set the chassis size as the sum of the slot of the adapter plus the slots of each
I/O module in the adapter backplane. For example, the adapter plus 4 I/O
modules uses a chassis size of 5. The adapter stores this chassis size setting in
non-volatile storage.
When the adapter’s non-volatile chassis size does not match the actual number
of modules present on its backplane, the adapter does not make any I/O
connections and an error occurs, as shown in the Module Properties dialog.
Adapter Replacement
It is important to note that during a connection request from the controller,
the chassis size setting for a 1734-AENT adapter is not communicated to the
adapter. You must always set this chassis size using a separate operation. This
includes situations when you are replacing an adapter. The adapter does not
make any I/O connections until it is configured with the appropriate chassis
size.
Empty Slots and RIUP Situations
The POINT I/O system does not have the ability to detect an empty terminal
base. Because of this, there are numerous situations in which you can
potentially configure a system that is unusable or one that exercises unintended
control.
In an attempt to address these situations, you must observe the following rules
for POINT I/O system construction and the removal and reinsertion of
modules:
Publication 1734-UM011D-EN-P - May 2011
About the Adapter 3
• A correct POINT I/O system does not have any empty terminal bases.
• After you cycle power, the adapter does not run any I/O until the
number of modules comprising the chassis equals the stored chassis
size.
– Because the adapter cannot detect empty terminal bases, it cannot
assume any safe operation until there is a match between the number
of modules indicating their presence in the chassis and what the
adapter has saved in non-volatile memory.
– Actual module identification (such as, electronic keying) is done
when connection establishment requests are received from the
controller or controllers.
• A module removed under power does not disrupt operation of the other
I/O modules.
– When you remove a module, the adapter determines what changed.
– Whenever you remove a module with an active connection from the
POINT I/O system, the adapter indicates this by flashing the
POINTBus Status LED red and reports a minor recoverable fault.
• If more than one contiguous module is removed under power,
connections to all modules in the contiguous missing module set are
disallowed until all modules are replaced. Because the adapter cannot
detect an empty base, it does not know the physical positioning of the
modules until all the missing modules are replaced.
• If a module separating two sets of contiguous missing modules is
removed, the two sets merge into a single set. All the modules must be
replaced before connections are permitted to any module in the set.
• If modules of different types are removed and returned to the wrong
locations, attempts to connect to these modules fail during verification
of the electronic ID (providing that keying has not been disabled).
• If modules of the same type are removed and returned to the wrong
locations, they accept connections from the controller or controllers and
reconfigure with the correct data once they pass their electronic keying
check.
• These removal and return conditions apply whether the system is under
power or not. If the system is under power, the situation arises
immediately. If the system is not under power, the situation arises in the
next power cycle.
Publication 1734-UM011D-EN-P - May 2011
4 About the Adapter
Cycle Power To a System for the First Time
When you cycle power to the POINT I/O for the first time, the adapter must
assign addresses to every module in the backplane. POINT I/O modules all
ship configured at the same address.
When you first apply power, we expect that all but one module on the
backplane exhibits a solid red Module Status LED.
One by one the adapter resets these modules and addresses them
appropriately. The amount of time that this operation takes is proportional to
the size of your POINT I/O system.

Hardware/Software Compatibility
What the Adapter Does
The 1734-AENT adapter and the applications described in this manual are
compatible with the following firmware revisions and software releases.
Contact Rockwell Automation if you need software or firmware upgrades to
use this equipment.
Product Firmware Revision/
Software Release
1734-AENT adapter 1.xx or later
1756-ENBT module 2.3 or later
Logix 5555 controller 11 or later
RSLogix 5000 software 11.11 or later
RSLinx software 2.3.1 or later
The 1734-AENT adapter performs the following primary tasks:
• Control of real-time I/O data (also known as implicit messaging) – the
1734-AENT adapter serves as a bridge between POINT I/O modules
and the network
• Support of messaging data for configuration and programming
information (also known as explicit messaging)
Use of the Common
The 1734-AENT adapter uses the Common Industrial Protocol (CIP). CIP is
the application layer protocol specified for EtherNet/IP, the Ethernet
Industrial Protocol (CIP)
Industrial Protocol, as well as for ControlNet and DeviceNet networks. It is a
message-based protocol that implements a relative path to send a message
from the producing device in a system to the consuming devices.
The producing device contains the path information that steers the message
along the proper route to reach its consumers. Since the producing device
holds this information, other devices along the path simply pass this
information; they do not need to store it.
This has the following significant benefits:
• You do not need to configure routing tables in the bridging modules,
which greatly simplifies maintenance and module replacement.
Publication 1734-UM011D-EN-P - May 2011
6 About the Adapter
• You maintain full control over the route taken by each message, which
enables you to select alternative paths for the same end device.
Understand the Producer/Consumer Model
Specify the Requested Packet Interval (RPI)
The CIP producer/consumer networking model replaces the old
source/destination (master/slave) model. The producer/consumer model
reduces network traffic and increases speed of transmission. In traditional I/O
systems, controllers poll input modules to obtain their input status. In the CIP
system, input modules are not polled by a controller. Instead, they produce
(multicast) their data either upon a change of state (COS) or periodically.
The frequency of update depends upon the options chosen during
configuration and where on the network the input module resides. The input
module, therefore, is a producer of input data, and the controller is a consumer
of the data.
The controller can also produce data for other controllers to consume. The
produced and consumed data is accessible by multiple controllers and other
devices over the EtherNet/IP network. This data exchange conforms to the
producer/consumer model.
The RPI is the update rate specified for a particular piece of data on the
network. The RPI can be specified for the adapter and include all of the I/O
modules communicating through it (using a rack-optimized connection) or
specified for a particular module (using direct connection).
When you add a module or an adapter to the I/O configuration of a
controller, you must enter the RPI as a parameter. This value specifies how
often to produce the data for that device. For example, if you specify an RPI of
50 ms, it means that every 50 ms the device should send its data to the
controller or the controller should send its data to the device.
Use RPIs only for devices that exchange data. For example, a ControlLogix
EtherNet/IP bridge module in the same chassis as the controller does not
require an RPI, because it is not a data-producing member of the system. Its
use is only as a bridge to remote racks.
Publication 1734-UM011D-EN-P - May 2011
About the Adapter 7
IMPORTANT
Support of Rack-optimized and Direct Connections
The 1734-AENT adapter supports both direct and rack-optimized
connections. A direct connection is a real-time data transfer link between the
controller and whatever module occupies the slot that the configuration data
references. Direct connection messaging occurs at a cyclic rate specified by the
RPI during configuration. A rack-optimized connection is a grouping of data
from more than one I/O module into a single block of data sent over a single
connection at the same data rate.
Rack-optimized connections reduce the total number of connections needed
to transfer data when using many I/O modules in a system. The following
example illustrates the benefit of rack-optimized connections.
Assume you set up a system that contains 8 digital I/O modules interfaced to a
1734-AENT adapter. If you use direct connections to transfer data to each of
the these I/O modules, you need 8 connections to transfer all of the data, one
to each of the 8 I/O modules. If you use a rack-optimized connection to
transfer the data, you only need a single connection – the connection to the
1734-AENT adapter.
Although rack-optimized connections offer an efficient
way to use resources, there are a few limitations on their
use.
• You can use only rack-optimized connections to
send data to and from digital I/O modules. Analog
or speciality I/O requires direct connections.
• All data is sent at the same time as the RPI rate of
the 1734-AENT adapter.
See the EtherNet/IP Performance and Application Guide, publication
number ENET-AP001
, for more information on connections.
Mix Rack-optimized and Direct Connections
You can mix communication formats for different I/O modules
communicating through the same adapter. I/O modules set up to use rack
optimization communicate at the rate of the RPI configured for the
1734-AENT adapter. I/O modules configured for direct communication
communicate at their own set RPIs and ignore the 1734-AENT adapter’s RPI.
Publication 1734-UM011D-EN-P - May 2011
8 About the Adapter
Before You Begin
To effectively use your adapter, note the following considerations.
Determine Compatibility
If using the adapter with a 1756-ENBT module or 1788-ENBT module, use
the following required firmware revisions for these bridge modules:
• 1756-ENBT firmware revision 2.3 or later
• 1788-ENBT firmware revision 1.33 or later
If you use the BootP Utility to assign IP addresses to the adapter, use revision
2.3.2 or later.
Understand Messaging
Class 3 (Explicit Message) requests through the 1734-AENT adapter to a
specific POINT I/O module may not always receive a response from the I/O
modules. In the case where the I/O module does not reply to the request, the
adapter responds with an error code indicating a timeout.
Establish I/O Connections
When you apply power to a POINT I/O system and establish I/O
connections, the outputs transition to the idle state, applying idle state data
before going to RUN mode. This occurs even when the controller making the
connection is already in RUN mode.
Configure Autobaud
The adapter cannot reconfigure an I/O module that you previously configured
to operate at a fixed communication rate. When you reuse a POINT I/O
module from another POINT I/O system, configure the module to autobaud
before using it with the adapter.
