Important Adapter
Considerations
Rockwell Automation Publication 1734-UM014B-EN-P - June 20131
Before you begin using your adapter, note the following important
considerations.
ATTENTION: You must use series C POINT I/O modules with the
adapter. Series A or B POINT I/O modules do not work with the adapter.
Chapter 1 About the Adapters
About the POINT I/O and
ArmorPOINT I/O
2 Port Adapters
The POINT I/O and ArmorPOINT I/O adapters provide connectivity to
EtherNet/IP networks for POINT I/O and ArmorPOINT I/O modules
respectively.
The POINT I/O adapter is for the I/O backplane that provides connectivity
through two RJ-45 connectors for 2-port pass-through support of daisy chain or
ring, and the existing star and tree network topologies.
Likewise, the ArmorPOINT I/O adapter provides the same connectivity
through two M12 Ethernet-keyed connectors. It ships with a terminating base for
use in the last I/O module on the backplane.
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-AENTR 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.
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 or
ArmorPOINT 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.
2Rockwell Automation Publication 1734-UM014B-EN-P - June 2013
About the Adapters Chapter 1
In an attempt to address these situations, you must observe the following rules for
I/O system construction and the
removal andreinsertion of modules.
• 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.
• 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.

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.
Adapter Features
Features of the adapters include:
• Use of EtherNet/IP messages encapsulated within standard TCP/UDP/IP
protocol
• Common application layer with ControlNet and DeviceNet networks
• Interfacing via Category 5 rated twisted pair cable
• Half/full duplex 10 Mbit or 100 Mbit operation
• DIN rail mounting for 1734-AENTR adapter/Wall or panel mounting for
1738-AENTR adapter
• Communication to and from other I/O modules on the same DIN rail for
1734-AENTR adapter/Communication to and from other I/O modules
in the chassis for 1738-AENTR adapter
• Communication supported by RSLinx software
• IP address assigned via standard BootP or DHCP tools
• I/O configuration via RSLogix 5000 software
• No network scheduling required
• No routing tables required
• Support of connections from multiple controllers simultaneously
You must use RSLogix 5000 to configure these features. For more details on
configuration, see Configuration Requirements
on in chapter 3.
What the Adapter Does
The I/O adapters perform the following primary tasks:
• Control of real-time I/O data (also known as implicit messaging) - the
adapter serves as a bridge between I/O modules and the network
• Support of messaging data for configuration and programming
information (also known as explicit messaging)

Hardware/Software
Compatibility
Use of the Common
Industrial Protocol (CIP)
The I/O adapters and the applications described in this manual are compatible
with the following firmware revisions and
Contact Rockwell Automation if you need software or firmware upgrades to use
this equipment

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.
software releases.
Understand the Producer/
Consumer Model
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.
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.
Rockwell Automation Publication 1734-UM014B-EN-P - June 20135
Chapter 1 About the Adapters
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.
Specify the Requested
Packet Interval (RPI)
Support of Rack-optimized
and Direct Connections
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.
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.
Analog, safety, and speciality modules cannot participate in the rack-optimized
connection; these modules require a direct I/O connection.
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
6Rockwell Automation Publication 1734-UM014B-EN-P - June 2013
About the Adapters Chapter 1
IMPORTANT
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.
See the EtherNet/IP Design Considerations Reference Manual,
publicationENET-RM002
for more information on connections.
Mixing Rack-optimized and Direct Connections
Chapter Summary
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.
In this chapter, you were introduced to the features of the POINT I/O and
ArmorPOINT I/O Adapters, and considerations for installation and usage.

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 use series C POINT I/O modules with the
adapter. Series A or B POINT I/O modules do not work with the adapter.
If you need to reset the adapter to factory defaults, see Work with the
Configuration Pages in Appendix B.
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
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.
.
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
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.
20Rockwell Automation Publication 1734-UM014B-EN-P - June 2013
When B is communicating with D, G (the configured Gateway for B) will route
the data from B to D through G2.

Set the Network Address
The adapters ship DHCP-enabled and with the switches set to 999. To change
the network address, do the following.
Set the Network Address for POINT I/O Adapter
• Use the thumbwheel switches located on the adapter. Press either the + or -
buttons to change the number.
• Use a Dynamic Host Configuration Protocol (DHCP) server, such as
Rockwell Automation BootP/DHCP.
• Retrieve the IP address from non-volatile memory.
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 255.255.255.0 . When
you use the thumbwheel to assign an address and set it 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 DHCP is not enabled, the adapter uses the IP address, along with other TCP
configurable parameters, stored in non-volatile memory.

This example shows the network address
set at 163.
Set the Network Address for ArmorPOINT I/O Adapter
• Adjust the switches in front of the module
• Use a Dynamic Host Configuration Protocol (DHCP) server such as
Rockwell Automation BootP/DHCP
• Retrieve the IP address from non-volatile memory
The adapter reads the switches first to determine if the switches are set to a valid
number. Set the network address by adjusting the three switches on the front of
the adapter.
Network Address Example
Use a small blade screwdriver to rotate the switches. Line up the small notch on
the switch with the number setting you wish to use. Valid settings range from
001…254.
Use the Rockwell BootP/
DHCP Utility
When you use the switches 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 255.255.255.0 . When
you use the switches to assign an address and set it to a valid number between
002...254, the adapter gateway address is set to 192.168.1.1.
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.
If DHCP is not enabled, the adapter uses the IP address, along with other TCP
configurable parameters, stored in non-volatile memory.
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 Utils 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.
