Chapter 1 Overview of the POINT I/O EtherNet/IP Adapter

If the thumbwheels are set to an invalid number, 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.

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, if your system consists of one adapter and four I/O modules, set the

chassis size to 5.

The adapter stores this chassis size setting in nonvolatile 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 nonvolatile

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.

The cause of error may be one of the following:

7. Remove power from the adapter and then address the error accordingly.

8. Once you have addressed the error, repeat Steps 1...5.

9. Once you have set the chassis size by using the thumbwheels, remove power

from the adapter and then set the thumbwheels according to the IP address

setting that you need.

For more information, see Set the Network Address for POINT I/O

Adapters on page 33.

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

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.

Error Action

Chassis size

mismatch

Make sure that the chassis size value matches the total number of the

adapter plus the I/O modules.

For example, if you have 1 adapter and 10 I/O modules, then the chassis

size is 11. Therefore, the thumbwheels must be set to 811.

Module fault Refer to the installation instructions publication for the affected module

for information on how to interpret its status indicators.

Rockwell Automation Publication 1734-UM018F-EN-E - May 2023 17

Overview of the POINT I/O EtherNet/IP Adapter Chapter 1

– 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 nonvolatile 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 indicator 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 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 indicator.

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.

18 Rockwell Automation Publication 1734-UM018F-EN-E - May 2023

Chapter 1 Overview of the POINT I/O EtherNet/IP Adapter

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.

• 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-optimization or

enhanced rack-optimization 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

Rockwell Automation Publication 1734-UM018F-EN-E - May 2023 19

Overview of the POINT I/O EtherNet/IP Adapter Chapter 1

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 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-

optimization, Enhanced

Rack-optimization, and

Direct Connections

The I/O adapter supports direct, rack-optimization, and enhanced rack-

optimization 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-optimization 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 specialty modules cannot participate in the rack-optimization

connection; these modules require an enhanced rack-optimization or direct I/O

connection.

Enhanced rack-optimization connections reduce the total number of

connections needed to transfer data when using many digital and analog, or

specialty modules in a system.

Rack-optimization 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-optimization connections.

20 Rockwell Automation Publication 1734-UM018F-EN-E - May 2023

Chapter 1 Overview of the POINT I/O EtherNet/IP Adapter

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-optimization connection to transfer the data,

you only need a single connection – the connection to the I/O adapter.

See the EtherNet/IP Device Level Ring Application Technique, publication

ENET-AT007

, for more information on connections.

Mixing Rack-optimization, Enhanced Rack-optimization, 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 or

enhanced 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-optimization RPI.

IMPORTANT

Although rack-optimization and enhanced rack-optimization connections

offer an efficient way to use resources, there are a few limitations on

their use:

• You can use only rack-optimization or enhanced rack-optimization

connections to send data to and from digital I/O modules.

• Safety modules, IO-Link modules, and third-party I/O modules can

not participate in enhanced rack-optimization connections.

• Enhanced rack-optimization does not support a listen only

connection. Do not use enhanced rack-optimization if your

application requires a connection for monitoring.

• 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-optimization or enhanced rack-optimization

connection, a direct connection to that I/O module is required.

Rockwell Automation Publication 1734-UM018F-EN-E - May 2023 21

Overview of the POINT I/O EtherNet/IP Adapter Chapter 1

Before You Begin

To effectively use your adapter, note the following considerations.

Determine Compatibility

If using the adapter with a 1756-ENBT module or 1768-ENBT module, use the

following required firmware revisions for these bridges:

• 1756-ENBT firmware revision 4.006 or later

• 1768-ENBT firmware revision 2.003 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.

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

Configure the Adapter with RSLogix 5000 or

Studio 5000 Logix Designer Application

Introduction

This chapter guides you through the steps required to configure your modules

using the RSLogix 5000 or Studio 5000 Logix Designer application. 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 Automation BOOTP/DHCP utility, version 2.3 or

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

third-party DHCP server.

• Use the Network Address thumbwheel switches.

• Have your network administrator configure the adapter via the network

DHCP server.

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 Automation

BOOTP/DHCP 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: Check the Product Compatibility and Download Center

(PCDC) to verify the compatibility between your POINT I/O module and

the POINT I/O adapter.

30 Rockwell Automation Publication 1734-UM018F-EN-E - May 2023

Chapter 3 Configure the Adapter with RSLogix 5000 or Studio 5000 Logix Designer Application

If you need to reset the adapter to factory defaults, see Work with the

Configuration Pages in Appendix A.

IMPORTANT

If you set the thumbwheels on the adapter to the value 888 and then

power cycle the module, the following will occur.

· 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 password for this page resets to the factory default (the word

password is the factory default password).

Note the value of the switches before you enter the 888 value,

because you return the adapter to those values once this process is

complete.

IMPORTANT

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 dotted-

decimal IP address as follows:

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

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.

10000000 00000001 00000000 00000001 is written as

128.1.0.1

Chapter 3 Configure the Adapter with RSLogix 5000 or Studio 5000 Logix Designer Application

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

EXAMPLE

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

Network 1

Network 2

128.1.0.1

128.2.0.1 128.2.0.2 128.2.0.3

128.1.0.2

These two bits of the Host ID are used to

extend the network ID.

Rockwell Automation Publication 1734-UM018F-EN-E - May 2023 33

Configure the Adapter with RSLogix 5000 or Studio 5000 Logix Designer Application Chapter 3

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 uses Gateway G2 to communicate with hosts not on Network 2.2.

Hosts B and C uses Gateway G to communicate with hosts not on Network 2.1.

When B is communicating with D, G (the configured Gateway for B) routes the

data from B to D through G2.

Set the

Network Address

The adapters ship DHCP-enabled and with the pen-push Network address

thumbwheels 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 pen-push thumbwheels on the adapter. Press either the + or -

button with a pen tip 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 nonvolatile memory.

Chapter 3 Configure the Adapter with RSLogix 5000 or Studio 5000 Logix Designer Application

The adapter reads the thumbwheels first to determine if the thumbwheels are set

to a valid number. You set the node address by using the 3-position pen-push

thumbwheel using a pen tip.

Note: Press a pen tip into the center and perpendicular to the + or the - button to

change the number. You only need a small amount of force to press the button

(approximately 2N).

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 thumbwheels 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 nonvolatile memory.

WARNING: When you change thumbwheels settings while power is

on, an electric 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 BOOTP/DHCP

Utility

The 1734-AENT/C adapter should be configured using only DHCP. The

Rockwell Automation BOOTP/DHCP utility is a standalone program that

incorporates the functionality of standard BOOTP software with a user-friendly

graphical interface the Utils directory on the RSLogix 5000 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.

In the BOOTP Request History panel you see the hardware addresses of

devices issuing BOOTP requests.

36 Rockwell Automation Publication 1734-UM018F-EN-E - May 2023

Chapter 3 Configure the Adapter with RSLogix 5000 or Studio 5000 Logix Designer Application

2. Double-click the hardware address of the device you want to configure.

The New Entry dialog appears with the device’s media access control

address (MAC).

3. Enter the IP address you want to assign to the device and click OK. The

device is added to the Relation List, displaying the MAC address and

corresponding IP address, host name, and Description (if applicable).

When the address displays in the IP address column in the Request

History section, the IP address assignment has been made.

4. 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.

5. 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 re-

enable DHCP.

Chapter 3 Configure the Adapter with RSLogix 5000 or Studio 5000 Logix Designer Application

Use DHCP Software to

Configure Your Adapter

DHCP (Dynamic Host Configuration Protocol) software automatically assigns

IP addresses to client stations logging on to 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

in Chapter 4 to configure the

adapter with a fixed IP address.

Implicit Protected Mode

Implicit Protected Mode is a state where the device is operational, but has

implemented defenses against disruptive changes that would take the product out

of service for the process. For more complete information on how Protected

Mode works, see EtherNet/IP Network Devices User Manual, publication

ENET-UM006

Implicit Protected Mode is a security enhancement that is automatically triggered

as soon as one of the following occur:

• The adapter bridges I/O connections.

• The adapter is a target of I/O connections.

This security enhancement occurs on the I/O module level and helps prevent

unauthorized configuration changes that can affect system behavior and cause

unintended and unforeseen changes.

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.

Rockwell Automation Publication 1734-UM018F-EN-E - May 2023 39

Configure the Adapter with RSLogix 5000 or Studio 5000 Logix Designer Application Chapter 3

Enter and Exit Implicit Protected Mode

The adapter enters Implicit Protected Mode as soon as I/O connections are

established through or to the adapter (status connection). The adapter exits

Implicit Protected Mode as soon as all I/O connections through or to the adapter

(status connection) are stopped.

Restrictions Imposed By Implicit Protected Mode

Implicit Protected Mode helps prevent access to services that are not required

after the device is configured and in normal operation. Protected Mode disables

features that can make the device vulnerable to disruptive actions. By doing so,

Protected Mode helps to reduce the attack surface.

When it is in Protected Mode, the adapter helps prevent execution of the

following tasks:

• Changing Ethernet configuration settings, such as port speed.

• Changing IP settings, such as IP address, mask, and DHCP mode.

• Updating the adapter firmware revision.

• Disabling or re-enabling external product ports.

• Performing remote adapter resets.

Perform Tasks When Restricted

If the adapter is in Implicit Protected Mode and you attempt to perform any of

the restricted tasks, you are alerted that such a task cannot be performed because

the adapter is in Implicit Protected Mode.

The following are example alerts that result from an attempt to set IP values on

the adapter when the adapter is in Implicit Protected Mode:

IMPORTANT

Protected Mode is not configurable.

Chapter 3 Configure the Adapter with RSLogix 5000 or Studio 5000 Logix Designer Application

• Studio 5000 Logix Designer application

• RSLinx software

If the adapter is not in Implicit Protected Mode, the adapter does not reject

attempts to perform the tasks that are described previously.

For example, after the adapter is initially powered up, but no I/O connections are

established yet, the adapter is not in Implicit Protected Mode. Additionally, if the

adapter is not in Implicit Protected Mode then you can attempt to update the

adapter firmware revision and the adapter does not reject the attempt.

Enable or Disable Web

Server

You can enable or disable the web server as an added security feature from

firmware revision 2.011 or later.

The web server is enabled by default from firmware revision 2.011 or later.

Disabling the web server in conjunction with using the Implicit Protected Mode

decreases the possibility of a security breach.

For more information on how to enable or disable the web server, see Enable

Disable the Web Server on page 97.

TIP

If the adapter enters Implicit Protected Mode each time the adapter

powers up, check application controllers to determine if there are active

I/O connections that are opened via the adapter.

Configure the Adapter for Direct Connection

in RSLogix 5000 or Studio 5000 Logix Designer

Application

Overview

This chapter guides you through the steps required to configure your modules

using the RSLogix 5000 or Studio 5000 Logix Designer application.

In this example, a ControlLogix controller communicates with I/O modules via

the adapter using a direct connection.

The adapter makes a direct connection to each of the modules referenced by the

data. The modules presented in this chapter use RSLogix 5000 software,

version 17, or later.

Set Up the Hardware

The following section describes how to set up the I/O Hardware.

In this example, a ControlLogix chassis contains the L63 controller in slot 1 and a

1756-ENBT bridge in slot 3. The 1734-AENT adapter is mounted 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 2, and a power supply (not shown).

ATTENTION: Check the Product Compatibility and Download Center

(PCDC) to verify the compatibility between your POINT I/O module and

the POINT I/O adapter.

44 Rockwell Automation Publication 1734-UM018F-EN-E - May 2023

Chapter 4 Configure the Adapter for Direct Connection in RSLogix 5000 or Studio 5000 Logix Designer Application

To work along with this example, set up your system as shown in the figure.

• In the example application, we assume that the L63 controller and

1756-ENBT module (firmware revision 4.006, or later) are in the slots

shown in the figure.

• Verify the IP addresses for your programming terminal, 1756-ENBT

module, and adapter.

• Verify the position (slot) of the I/O modules on the DIN rail.

• Verify that you connected all wiring and cabling properly.

• Be sure you configured your communication driver (for example,

AB_ETH-1 or AB-ETHIP-1) in RSLinx software, as described in

Appendix B

in this manual.

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-optimization I/O connection.

• Remove the rack-optimization connection if there are no modules

participating in it.

Chapter

Configure the Adapter for Direct Connection,

Rack Optimization, and Enhanced Rack

Optimization

Overview

This chapter guides you through the steps required to configure your AENT

adapter with direct, rack-optimization, and enhanced rack-optimization I/O

connections using RSLogix 5000 or Studio 5000 Logix Designer application.

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 or

enhanced 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-optimization or enhanced rack-optimization 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,

version 17 or later.

ATTENTION: Check the Product Compatibility and Download Center

(PCDC) to verify the compatibility between your POINT I/O module and

the POINT I/O adapter.

Chapter 5 Configure the Adapter for Direct Connection, Rack Optimization, and Enhanced Rack Optimization

Set Up the Hardware

The following section describe how to set up the I/O Hardware.

Set Up the POINT I/O Hardware

In this example, a ControlLogix chassis contains the L63 controller in slot 1 and a

1756-ENBT bridge 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 are not controlled by this Logix controller in slots 2 and 4.

To work along with this example, set up your system as shown in the figure.

• Note that in the example application, the Logix controller, and

1756-ENBT module (firmware revision 4.006 or later) we assume are in

the slots shown in the figure.

• Verify the IP addresses for your programming terminal, 1756-ENBT

module, and I/O adapter.

• Verify the position (slot) of the I/O modules on the DIN rail.

• Verify that you properly connected all wiring and cabling.

• Make sure you configured your communication driver (such as

AB_ETH-1 or AB-ETHIP-1) in the RSLinx software. See Configure the

RSLinx Ethernet Communication Driver in Appendix B.

Access Module Data

Use the following information to use the I/O adapter data in the ladder logic

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-optimization 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-

optimization and direct connections.

The slot status bits indicate that we installed the module in slot 2 with it

operating correctly:

0 = module participating with no errors, and

1 = module not participating or connection error (typically, module

removed/missing).
