2About 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 their chassis 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.

Publication 1734-UM014A-EN-P - November 2010
About the Adapters 3
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 removal and reinsertion 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 equals the 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.

Publication 1734-UM014A-EN-P - November 2010
4About the Adapters
• 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

The I/O adapters and the applications described in this manual are compatible
with the following firmware revisions and software releases.

About the Adapters 5

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)
Use of the Common
Industrial Protocol (CIP)
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.

6About the Adapters
• 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
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.
Specify the Requested
Packet Interval (RPI)
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.

Publication 1734-UM014A-EN-P - November 2010
About the Adapters 7
Support of Rack-optimized
and Direct Connections
The I/O adapters supports both direct and rack-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 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.
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 adapter.
I/O modules configured for direct communication communicate at their own
individual RPIs and ignore the rack-optimized RPI.
IMPORTANT
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.

Mount the I/O Adapter
Use the following procedures to mount the I/O adapters on a new system
before you install any I/O modules.
Mount a 1734-FPD module in the slot next to the I/O adapter when applying
field power. You can also use the 24V DC to power the adapter to supply field
power, where no FPD is necessary. Refer to Point I/O Field Potential
Distribution Module Installation Instructions, publication 1734-IN059 for
more information.

Mount the POINT I/O Adapter on a DIN Rail
Position the I/O adapters vertically above the DIN rail.
1. Make sure that the DIN rail lock is in horizontal position.
2. Press down firmly to install the adapter on a DIN rail, noting that the
locking mechanism locks the adapter to the DIN rail.
3. Set the network address thumbwheel switches to the desired value. See
Set the Network Address on page 21 for more information on setting
the IP address.
Mount the ArmorPOINT I/O Adapter and Base on a Wall or Panel
To mount the ArmorPOINT I/O adapter on a wall or panel, use the screw
holes provided in the ArmorPOINT I/O adapter.
WARNING
If you connect or disconnect the Ethernet cable with power applied to
this module or any device on the network, 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.
IMPORTANT
The ArmorPOINT I/O adapter must be mounted on a grounded
metal mounting plate or other conductive surface.
