Chapter 1 Overview of the 1734 POINT I/O EtherNet/IP Adapter
Important Adapter
Considerations
Before you begin using your adapter, note the following important
considerations.
ATTENTION: You must only use Series C and above POINT I/O modules
with 1734-AENT EtherNet/IP Adapters. Series A or Series B POINT I/O
modules do not work with 1734-AENT EtherNet/IP Adapters (does not
apply to POINTGuard modules).
Set the Chassis Size
The I/O adapters for EtherNet/IP require configuration of theirchassis size
before you can make any I/O connections. The factory default setting for the
chassis size is one slot, which represents the adapter by itself.
You must set the chassis size to a number equaling one slot for the adapter plus
one slot for each I/O module present in the backplane of the adapter.
For example, a POINT I/O system consisting of a 1734-AENT adapter, one
1734-IB8, one 1734-OB8, and one 1734-OB8S POINT Guard I/O module uses
a chassis size of 4. The adapter stores this chassis size setting in non-volatile
memory.
Each time the adapter is powered up, the adapter compares the number of I/O
modules present on its backplane to the chassis size value from non-volatile
memory. The adapter does not allow any I/O connection until the number of
I/O modules present equals the chassis size value minus one for the adapter itself.
4Rockwell Automation Publication 1734-UM018B-EN-P - October 2013
Overview of the 1734 POINT I/O EtherNet/IP Adapter Chapter 1
Adapter Replacement
Note that during a connection request from the controller, the chassis size setting
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 allow any I/O connections until it is configured with the
appropriate chassis size and the proper number of POINT I/O modules are
present.
Empty Slots and RIUP Situations
The POINT I/O system cannot detect an empty terminal base. For this reason,
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
I/O system construction and the
• A correct I/O system does not have any empty terminal bases.
• After you cycle power, the adapter will not allow any I/O connections
until the number of modules comprising the chassis plus one for the
adapter equalsthe stored chassis size.
– 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 because it cannot detect
empty terminal bases.
– Actual module identification (such as, electronic keying) is done when
connection establishment requests are received from the controller or
controllers.
• A POINT I/O module removed under power does not disrupt operation
of the other I/O modules. On the other hand, ArmorPOINT I/O
modules are not intended to be removed under power.
– When you remove a module, the adapter detects 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.
removal andreinsertion of modules.
Rockwell Automation Publication 1734-UM018B-EN-P - October 20135
Chapter 1 Overview of the 1734 POINT I/O EtherNet/IP Adapter
• If modules of different types are removed and returned to the wrong
locations, attempts to connect to these modules will 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 situations exist 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.
Power Up a System for the First Time
When you power the I/O for the first time, the adapter must assign slot addresses
to every module in the backplane. All I/O modules ship configured at the same
address.
Use of the Common
Industrial Protocol (CIP)
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 I/
O system.
The adapter uses the Common Industrial Protocol (CIP). CIP is the application
layer protocol specified for EtherNet/IP, the Ethernet 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 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.
• You maintain full control over the route taken by each message, which
enables you to select alternative paths for the same end device.
6Rockwell Automation Publication 1734-UM018B-EN-P - October 2013
Overview of the 1734 POINT I/O EtherNet/IP Adapter Chapter 1
Understand the Producer/
Consumer Model
Specify the Requested
Packet Interval (RPI)
The CIP producer and consumer networking model replaces the old source and
destination (master and slave) model. The producer and 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 or
unicast) their data either upon a change of state (COS) or periodically.
Multicast is the default mode for version 17 Logix and earlier controllers and
unicast is the default for version 18 with multicast as a selectable option.
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 also produces 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 and consumer model.
The Requested Packet Interval or 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 in the I/O system (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 and the controller
should send the consumed (output) 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.
Support for Rack-optimized
and Direct Connections
The I/O adapters supports both direct andrack-optimized connections. A direct
connection is a real-time data transfer link between the controller and the module
occupying the slot that the configuration data references.
Direct I/O connections occur at a cyclic rate specified by the RPI during
configuration. A rack-optimized connection is a grouping of data from one or
more digital I/O modules into a single block of data sent over a single connection
at the same data rate.
Rockwell Automation Publication 1734-UM018B-EN-P - October 20137
Chapter 1 Overview of the 1734 POINT I/O EtherNet/IP Adapter
IMPORTANT
Rack-optimized connections reduce the total number of connections needed to
transfer data when using many digital I/O modules in a system. The following
example illustrates the benefit of rack-optimized connections.
Assume you set up a system that contains eight digital I/O modules interfaced to
an adapter. If you use direct connections to transfer data to each of the these I/O
modules, you need eight connections to transfer all of the data, one to each of the
eight I/O modules. If you use a rack-optimized connection to transfer the data,
you only need a single connection – the connection to the I/O 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 I/O adapters.
If the update rate required for a digital module is different from the
RPI of the rack-optimized connection, a direct connection to that
digital I/O module is required.
Before You Begin
See the EtherNet/IP Embedded Switch Technology Application Guide,,
publication ENET-AP005
, for more information on connections.
Mixing 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 adapter. I/O modules
configured for direct communication communicate at their own individual RPIs
and ignore the rack-optimized RPI.
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.
8Rockwell Automation Publication 1734-UM018B-EN-P - October 2013
Overview of the 1734 POINT I/O EtherNet/IP Adapter Chapter 1
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.
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.

Chapter 2 Install Your 1734 POINT I/O EtherNet/IP Adapter
Replace An Adapter
Use these procedures to install a replacement POINT I/O adapter to an existing
system.
1. Disconnect the Ethernet connector(s) from the adapter.
2. Pull up on the Removable Terminal Block (RTB) handle to remove the
terminal block.
3. Remove the adjacent module from its mounting base.
4. Use a small bladed screwdriver to rotate the DIN rail locking screw
(orange) to a vertical position. This releases the locking mechanism.
5. Lift the adapter straight up to remove.
6. Slide the safety end cap up to remove it, which exposes the backplane and
power connections.
ATTENTION: Do not discard the end cap. Use this end cap to cover the
exposed interconnections on the last mounting base on the DIN rail.
Failure to do so could result in equipment damage or injury from electric
shock.
WARNING: When you insert or remove the module while backplane
power is on, an electrical arc can occur. This could cause an explosion
in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before
proceeding. Repeated electrical arcing causes excessive wear to contacts
on both the module and its mating connector. Worn contacts may create
electrical resistance that can affect module operation.

Introduction
This chapter guides you through the steps required to configure your modules
using the RSLogix 5000 software. Note that the modules presented in this
chapter can be configured using RSLogix 5000 software,version 17, or later.
Before using your adapter in an EtherNet/IP network, you need to configure it
with an IP address, subnet mask, and optional Gateway address. This chapter
describes these configuration requirements and the procedures for providing
them. Here are ways you can do this:
• Use the Rockwell BootP/DHCP utility, version 2.3or later, that ships
with RSLogix 5000 or RSLinx software.
– You can also use this utility to reconfigure a device with an IP address
you must change.
• Use a
• Use the Network Address thumbwheel switches.
• Have your network administrator configure the adapter via the network

Configuration
Requirements
Before you can use your adapter, you must configure its IP address, its subnet
mask, and, optionally, a gateway address. You can use the Rockwell BootP utility,
version 2.3 or later, to perform the
configuration. You can also use a DHCP
server or the network address switches to configure these parameters.
ATTENTION: You must only use Series C and above POINT I/O modules
with 1734-AENT EtherNet/IP Adapters. Series A or Series B POINT I/O
modules do not work with 1734-AENT EtherNet/IP Adapters (does not
apply to POINTGuard modules).
If you need to reset the adapter to factory defaults, see Work with the

EXAMPLE
If using the BootP/DHCP utility, you need to know the Ethernet
hardware address of your adapter. Rockwell Automation assigns each
1734-AENT adapter a unique 48-bit hardware address at the factory.
The address is printed on a label on the side of your 1734-AENT
adapter as shown in the figure. It consists of six hexadecimal digits
separated by colons. This address is fixed by the hardware and cannot
be changed.
If you change or replace the 1734-AENT adapter, you must enter the
new Ethernet hardware address of the adapter when you configure
the new adapter.
IP Address
The IP address identifies each node on the IP network (or system of connected
networks). Each TCP/IP node on a network (including the adapter) must have a
unique IP address.
The IP address is 32 bits long and has a Network ID part and Host ID part.
Networks are classified A, B, C, (or other). The class of the network determines
how an IP address is formatted
.
You can distinguish the class of the IP address from the first integer in its dotteddecimal IP address as follows:
Range of first integerClassRange of first integerClass
0 1…127A192…223C
128…191B224… 255other
Each node on the same physical network must have an IP address of the same
class and must have the same network ID. Each node on the same network must
have a different Host ID thus giving it a unique IP address.
IP addresses are written as four decimal integers (0…255) separated by periods
where each integer gives the value of one byte of the IP address
.
For example, the 32-bit IP address:
10000000 00000001 00000000 00000001 is written as
128.1.0.1

Gateway Address
This section applies to multi-network systems. If you have a single network
system, refer to the next section.
The Gateway Address is the default address of a network. It provides a single
domain name and point of entry to the site. Gateways connect 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. The figure shows gateway G
connecting Network 1 with Network 2.
When host B with IP address 128.2.0.1 communicates with host C, it knows
from C’s IP address that C is on the same network. in an Ethernet environment, B
can then resolve C’s IP address into a hardware address (MAC address) and
communicate with C directly.
When host B communicates with host A, it knows from A’s IP address that A is
on another network (the network IDs are different). In order to send data to A, B
must use the IP address of the gateway connecting the two networks. In this
example, the gateway’s IP address on Network 2 is 128.2.0.3.
The gateway has two IP addresses (128.1.0.2 and 128.2.0.3). The first must be
used by hosts on Network 1 and the second must be used by hosts on Network 2.
To be usable, a gateway of a host must be addressed using a network ID matching
its own.

Subnet Mask
The subnet mask is used for splitting IP networks into a series of subgroups, or
subnets. The mask is a binary pattern that is matched up with the IP address to
turn part of the Host ID address field into a field for subnets
Take Network 2 (a Class B network) in the previous
example and add another physical network. Selecting the
following subnet mask would add two additional
network ID bits, allowing for four physical networks:
11111111 11111111 11
000000 00000000 = 255.255.192.0
Two bits of the Class B host ID are used to extend the network ID. Each unique
combination of bits in the part of the Host ID where subnet mask bits are 1
specifies a different physical network.
.
The new configuration is:
A second network with Hosts D and E was added. Gateway G2 connects
Network 2.1 with Network 2.2.
Hosts D and E will use Gateway G2 to communicate with hosts not on
Network 2.2.
Hosts B and C will use Gateway G to communicate with hosts not on
Network 2.1.
Rockwell Automation Publication 1734-UM018B-EN-E - October 201321
When B is communicating with D, G (the configured Gateway for B) will route
the data from B to D through G2.

Network address thumbwheel
Press either the + or - buttons
to change the number and
assign the IP address.
Set the Network Address
The adapters ship DHCP-enabled and with the Network address thumbwheel
switches set to 999. You can set the network Internet Protocol (IP) address as
follows.
Set the Network Address for POINT I/O Adapters
• Use the thumbwheel switches located on the adapter. Press either the + or -
buttons to change the number and assign the IP address.
• Use a Dynamic Host Configuration Protocol (DHCP) server, such as
Rockwell Automation BootP/DHCP.
• Retrieve the IP address from non-volatile memory.
22Rockwell Automation Publication 1734-UM018B-EN-E - October 2013
The adapter reads the thumbwheel switches first to determine if the switches are
set to a valid number. You set the node address by using the 3-position
thumbwheel switch. Press the + or - buttons to change the number. Valid settings
range from 001…254.
When you use the thumbwheel to assign an address and set it to 001, the adapter
gateway address is set to 0.0.0.0. and the subnet mask is set to 255.255.255.0 .
When you use the thumbwheel to assign an IP address between 002...254, the
adapter gateway address is set to 192.168.1.1.
The adapter does not have a host name assigned, or use any Domain Name
System when using the thumbwheel settings.
If the switches are set to an invalid number (for example, 000 or a value greater
than 254 excluding 888), the adapter checks to see if DHCP is enabled. If DHCP
is enabled, the adapter requests an address from a DHCP server. The DHCP
server also assigns other Transport Control Protocol (TCP) parameters.
Configure the Adapter with RSLogix5000 software Chapter 3
If DHCP is not enabled, the adapter uses the IP address, along with other TCP
configurable parameters, stored in non-volatile memory.
WARNING: When you change switch settings while power is on, an
electrical arc can occur. This could cause an explosion in hazardous
location installations.
Be sure that power is removed or the area is nonhazardous before
proceeding.
Use the Rockwell BootP/
DHCP Utility
The Rockwell BootP/DHCP utility is a standalone program that incorporates
the functionality of standard BootP software with a user-friendly graphical
interface. It is located in the Util s directory on the RSLogix5000 software
installation CD. The adapter must have DHCP enabled (factory default and the
network address switches set to an invalid value) to use the utility.
To configure your adapter using the BootP utility, perform the following steps:
1. Run the BootP software.
2. In the BOOTP Request History panel you see the hardware addresses of
devices issuing BootP requests.

Configure the Adapter with RSLogix5000 software Chapter 3
5. When the address displays in the IP Address column in the Request
History section, the IP address assignment has been made.
6. To make this configuration static in the device, highlight the device in the
Relation List panel, and click the Disable BOOTP/DHCP button.
When power is cycled to the device, it uses the configuration saved in nonvolatile memory and will not issue a DHCP request.
7. To enable DHCP for a device with DHCP disabled, highlight the device
in the Relation List, and click the Enable DHCP button.
You must have an entry for the device in the Relation List panel to reenable DHCP.
Save the Relation List
You can save the Relation List for later use. To save the Relation List, perform the
following steps:

Configure the Adapter with RSLogix5000 software Chapter 3
Use DHCP Software to
Configure Your Adapter
DHCP (Dynamic Host Configuration Protocol) software automatically assigns
IP addresses to client stations logging onto a TCP/IP network.
DHCP is based on BootP and maintains some backward compatibility. The main
difference is that BootP was designed for manual configuration, while DHCP
allows for dynamic allocation of network addresses and configurations to newly
attached devices.
Be cautious about using DHCP software to configure your adapter. A DHCP
server typically assigns a finite lease time to the offered IP address.
When 50% of the leased time has expired, the adapter attempts to renew its IP
address with the DHCP server.
The possibility exists that the adapter will be assigned a different IP address,
which would cause the adapter to cease communicating with the ControlLogix
controller.
See Configure the Adapter with Fixed IP Address
adapter with a fixed IP address.
ATTENTION: To avoid unintended control or loss of control, the
I/O adapter must be assigned a fixed IP address. A dynamically provided
IP address should be used only at initial configuration. If a DHCP server is
used, it must be configured to assign the same IP address to your adapter.
Failure to observe this precaution may result in unintended machine motion
or loss of process control.

Recover From an
Overloaded Adapter
Each I/O connection established with the I/O adapter consumes a portion of
microprocessor bandwidth. The amount of bandwidth used by a connection
depends on several variables, such as the requested packet interval (RPI), number
of I/O modules involved in the connection, and rate of change of the I/O.
The AENT adapter continuously monitors this bandwidth and rejects requests
for new I/O connections when there is insufficient bandwidth available to
support the new connection.
The condition where the I/O adapters cannot support the connection due to a
limit of the bandwidth of the microprocessor is shown on the Connection tab of
the Module Properties dialog.
If you encounter this condition, the only action you can take is to alter the
existing connections to reduce the amount of microprocessor bandwidth
consumed. The most likely fixes for this condition include the following:
• Increase the RPI.
• Decrease the number of connections.
• Remove modules from the rack-optimized I/O connection.
• Remove the rack-optimized connection if there are no modules
participating in it.

Software
Overview
This chapter guides you through the steps required to configure your AENT
adapter with both direct and rack-optimized I/O connections using
RSLogix 5000 software.
You can mix I/O connection 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 adapter.
I/O modules controlled by a direct I/O connection communicate at their own set
RPI. The RPI of the rack-optimized I/O connection has no bearing on the direct
I/O connections. The modules presented in this chapter have a configuration
using RSLogix 5000 software, revision 11. The chapter contains the following

Set Up the POINT I/O Hardware
In this example, a ControlLogix chassis contains the L63controller in slot 1 and a
1756-ENBT bridge module in slot 3. In this example, we mounted the
1734-AENT adapter on a DIN rail in slot 0, with a 1734-OW2/C relay output
module in slot 1, a 1734-OV4E/C sink output module in slot 3, and two other
POINT I/O modules which will not be controlled by this Logix controller in
slots 2 and 4.

program:
• POINT_IO_Adapter — the name you gave to your EtherNet adapter
• # — slot number of POINT I/O module
• C — configuration, I = input, O = output
Use the controller tags in your ladder program to read input data or write output
data.
• For ControlLogix controller information, refer to ControlLogix System
User Manual, publication 1756-UM001
• Slot Status Bits: The Slot Status bits display the connection status for each
of the POINT I/O modules that use a rack-optimized connection.
– Bit 0 is reserved for the adapter and always reports a value of 1.
– Each of the other bits (1 to 63) correspond to a POINT I/O module
that you install in the POINT I/O backplane.
– In this example, we configured the 1734-AENT adapter for both rack-
optimized and direct connections.
The slot status bits indicate that we installed the module in slot 2 with it
operating correctly:

Work with the
Configuration Pages
To wo rk wi th th eConfiguration pages, follow these procedures.
The values on these pages are in non-volatile memory. Changes to
these parameters do not take effect until you reset or cycle power
through the I/O adapters.
If you set the value of the I/O adapters switch to 888and then
power cycle the module, the following occurs:
· The DHCP Enabled function is enabled (set to True).
· The Ethernet link is negotiated automatically. The Auto Negotiate
function is set to True.
· The web server is enabled. The Disabled Web Server function is
disabled.
· The Ethernet port are disabled. Both ports are re-enabled once the
switches are returned to their previous value and power is cycled.
· The password for this page resets to the factory default whih is
"password".
Note the value of the switches before you enter the 888 value
because you must return the adapter to those values once this
process is complete.
