Terminology
Refer to the table for the meaning of common terms.
Term
BootP
Bridge
CIP
Connection
Consumer
Definition
BootP (Bootstrap Protocol) is a low-level protocol that provides configurations to other nodes on a TCP/IP network. BootP configuration files let you automatically assign IP addresses to an
Ethernet module. You can also obtain subnet masks and gateway addresses from BootP.
A node between two similar communication subnets where protocol translation is minimal.
Control and information protocol, the EtherNet/IP application layer uses the producer/consumer networking model. In this model one producer broadcasts (multicasts) the data once to all the consumers.
All consumers see the data simultaneously and may choose whether to consume (receive) the data or not. Delivery time is consistent, no matter how many consumers there are.
The communication mechanism from the controller to another module in the control system, usually used to exchange I/O data.
A destination device in the CIP networking model. See CIP.

Term
CSMA/CD
Determinism
DHCP
Definition
Carrier sense multiple access/collision detection is the access method used in Ethernet. When a device wants to gain access to the network, it checks to see if the network is quiet (senses the carrier).
If it is not, it waits a random amount of time before retrying. If the network is quiet and two devices access the line at exactly the same time, their signals collide. When the collision is detected, they both back off and each waits a random amount of time before retrying.
The ability to predict when information will be delivered. Important in time-critical applications.
The dynamic host configuration protocol is an Internet protocol, similar to BootP, for automating the configuration of computers that use TCP/IP. DHCP can be used to automatically assign IP addresses, to deliver IP stack configuration parameters, such as the subnet mask and default router, and to provide other configuration information, such as the addresses for printer, time, and news servers.
DNS
The 1734-AENT factory default is DHCP enabled. When you apply power, the module sends a message containing its hardware address to any DHCP server on the network. The server(s) replies by sending a message with an appropriate IP address for the adapter. The adapter responds by acknowledging to a server that it will use the offered IP address.
The domain name system is a hierarchical, distributed method of organizing the name space of the Internet. The DNS administratively groups hosts into a hierarchy of authority that allows addressing and other information to be widely distributed and maintained. A big advantage to the DNS is that using it eliminates dependence on a centrally-maintained file that maps host names to addresses.
Ethernet
EtherNet/IP
A physical layer standard using carrier sense multiple access with collision detection (CSMA/CD) methods.
Ethernet industrial protocol applies a common application layer (CIP) over Ethernet by encapsulating messages in TCP/UDP/IP.
Ethernet network A local area network designed for the high-speed exchange of information between computers and related devices.
Explicit messaging Non-time critical messaging used for device configuration and data collection, such as downloading programs or peer-to-peer messaging between two PLC units.
Full duplex
Fully qualified domain name
Gateway
A mode of communication that allows a device to send and receive information at the same time, effectively doubling the bandwidth.
A fully qualified domain name (FQDN) is a domain name that includes all higher level domains relevant to the entity named. If you think of the DNS as a tree-structure with each node having its own label, a fully qualified domain name for a specific node would be its label followed by the labels of all the other nodes between it and the root of the tree. For example, for a host, a FQDN would include the string that identifies the particular host, plus all domains of which the host is a part, up to and including the top-level domain (the root domain is always null). For example, PARIS.NISC.SRI.COM is a fully qualified domain name for the host at 192.33.33.109.
A module or set of modules that allows communications between nodes on dissimilar networks.
Preface ix
Term
Hardware address Each Ethernet device has a unique hardware address (sometimes called a MAC address) that is 48 bits. The address appears as six digits separated by colons (such as, xx:xx:xx:xx:xx:xx). Each digit has a value between 0 and 255 (0x00 to 0xFF). This address is assigned in the hardware and cannot be changed. The hardware address is required to identify the device if you are using a BOOTP utility.
Host name
Definition
The host name is the unique name for a computer within its domain.
It's always the first element of a full name, and, with its domain and top-level domain suffix, creates the unique name of that computer on the Internet. For example, let's say a trading website is www.trading.com. The host name is www, which is not unique on the web, but is unique within the trading domain.
Hub
Implicit messaging Real-time messaging of I/O data.
IP Internet protocol that provides the routing mechanism for messages.
All messages contain not only the address of the destination station, but the address of a destination network, which allows messages to be sent to multiple networks within an organization or around the world.
IP address A 32-bit identification number for each node on an Internet Protocol network. These addresses are represented as four sets of 8-bit numbers (numbers from 0 to 255), with decimals between them. Each node on the network must have a unique IP address.
Latency
The host name can also refer to the fully qualified domain name
(FQDN), or in this example, www.trading.com. Both naming methods seem to be used interchangeably in various documents. For the purposes of this document, the host name will refer to the FQDN, or as in this example, www.trading.com.
A central connecting device that joins devices together in a star configuration. Hubs are generally not suitable for use in I/O control systems, since they are time-critical applications that cannot tolerate lost packets.
Multicast
Producer
Rack-optimized
Subnet mask
The time between initiating a request for data and the beginning of the actual data transfer.
In the CIP producer/consumer model, one producer multicasts
(broadcasts) the data once to all the consumers.
The source of information in the CIP networking model. See CIP.
A physical and logical collection of application modules.
Switch
TCP
An extension of the IP address that allows a site to use a single net
ID for multiple networks.
A network device that cross connects devices or network segments.
A switch provides each sender/receiver the full network bandwidth
(2x in full duplex mode), reduces collisions, and increases determinism.
The transport control protocol is a more reliable but slower transport protocol than UDP. It is used for explicit (not time critical) messaging in EtherNet/IP.

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

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

4 About the Adapter
Adapter Features
Cycle Power To a System for the First Time
When you cycle power to the POINT I/O for the first time, the adapter must assign addresses to every module in the backplane. POINT I/O modules all ship configured at the same address.
When you first apply power, we expect that all but one module on the backplane exhibits a solid red Module Status LED.
One by one the adapter resets these modules and addresses them appropriately. The amount of time that this operation takes is proportional to the size of your POINT I/O system.
The 1734-AENT adapter has the following features:
• 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
• Communication to and from other POINT I/O modules on the same
DIN rail
• 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

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

Configure the Adapter for Your EtherNet/IP
Network
What This Chapter Contains
Before using your adapter in an EtherNet/IP network, 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 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 switch.
• Have your network administrator configure the adapter via the network server.
See the table for a list of where to find information in this chapter.

Configuration
Requirements
Before you can use your adapter, you must configure its IP address, its subnet mask, and, optionally, 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.

IMPORTANT
IP address Ethernet address (MAC)
43519
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 will be 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.
Configure the Adapter for Your EtherNet/IP Network 17
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
1734-AENT adapter) must have a unique IP address.
The IP address is 32 bits long and has a net 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:
Range of first integer Class
0 …127 A
128 …191 B
Range of first integer Class
192 … 223 C
224 … 255 other
Each node on the same physical network must have an IP address of the same class and must have the same net 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.
EXAMPLE
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.
Publication 1734-UM011D-EN-P - May 2011
18 Configure the Adapter for Your EtherNet/IP Network
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.

Network 1
128.1.0.2

B C
128.2.0.3
128.2.0.1
128.2.0.2
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 net IDs are different). In order to send data to A, B must have 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 host’s gateway must be addressed using a net 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 net ID bits, allowing for four physical networks:
11111111 11111111 11000000 00000000 = 255.255.192.0
These two bits of the Host ID are used to extend the net ID.
Two bits of the Class B host ID are used to extend the net 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 adapter reads the thumbwheel switches only when you cycle power to determine if the switches are set to a valid number. Press either the + or - buttons to change the number.
Valid settings range from 001 to 254. When the switches are set to a valid number, the adapter’s IP address will be 192.168.1.xxx (where xxx represents the number set on the switches). The adapter’s subnet mask will be
255.255.255.0 and the gateway address is set to 0.0.0.0. The adapter will 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 (such as 000 or a value greater than
254), 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 will also assign other Transport Control Protocol (TCP) parameters.
If DHCP is not enabled, the adapter will use the IP address (along with other
TCP configurable parameters) stored in nonvolatile memory. The factory default switch setting is 999, and DHCP is enabled.
Use the Rockwell
BootP/DHCP Utility
The Rockwell Automation BootP/DHCP utility is a stand alone program that incorporates the functionality of standard BootP software with a user friendly graphical interface. It is located in the Utils directory on the RSLogix 5000 software installation CD. The 1734-AENT adapter must have DHCP enabled
(factory default and the network address switches set to an illegal 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.
Publication 1734-UM011D-EN-P - May 2011
Configure the Adapter for Your EtherNet/IP Network 21
2. Double-click the hardware address of the device you want to configure.
You see the New Entry dialog with the device’s Ethernet 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 Ethernet Address
(MAC) and corresponding IP Address, Hostname, and Description (if applicable).
When the address displays in the IP Address column in the Request
History section, it signifies that the IP address assignment has been made.
4. To assign this configuration to 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 you assigned and 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.
Publication 1734-UM011D-EN-P - May 2011
22 Configure the Adapter for Your EtherNet/IP Network
You must have an entry for the device in the Relation List panel to re-enable DHCP.
Save the Relation List
You can save the Relation List to use later. To save the Relation List perform the following steps:
1. Select Save As... from the File menu.
Publication 1734-UM011D-EN-P - May 2011
Configure the Adapter for Your EtherNet/IP Network 23
The Save As dialog appears.
2. Select the folder you want to save to.
3. Enter a file name for the Relation List (for example, control system configuration), and click Save.
You can leave the Save as type at the default setting:
Bootp Config Files (*.bpc).
You can then open the file containing the Relation List at a later session.
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 1734-AENT 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.
Publication 1734-UM011D-EN-P - May 2011
24 Configure the Adapter for Your EtherNet/IP Network
ATTENTION
To avoid unintended control, the 1734-AENT adapter must be assigned a fixed IP address. The IP address of this adapter should not be dynamically provided. If a DHCP server is used, it must be configured to assign a fixed IP address for your adapter.
Failure to observe this precaution may result in unintended machine motion or loss of process control.

6. Click the Refresh button to verify the changes.
Each POINT I/O connection established with the 1734-AENT adapter consumes a portion of the microprocessor’s bandwidth. The amount of bandwidth used by a connection depends on a number of variables, including the requested packet interval (RPI), the number of POINT I/O modules involved in the connection, and the rate of change of the I/O.
The 1734-AENT adapter continuously monitors this bandwidth and rejects requests for new connections when there is insufficient bandwidth available to support the new connection.
The condition where the 1734-AENT adapter cannot support the connection due to a limit of the microprocessor’s bandwidth is shown in the following dialog.
Publication 1734-UM011D-EN-P - May 2011
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.

Access Module Data
Use the following information to use the 1734 POINT I/O Ethernet 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
Publication 1734-UM011D-EN-P - May 2011
This value indicates that slot 2 is the only module participating in the rack-optimized connection with no errors.
Use the controller tags in your ladder program to read input data or write output data.
• For RSLogix 5000 programming instructions, refer to RSLogix 5000
Getting Results, publication 9399-RLD300GR .
• 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…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:
• 0=module participating with no errors and
• 1=module not participating or connection error (typically, module removed/missing).

RSLogix 5000 software, version 11, compatibility.
The 1734-232ASC/A (series A) is presently the only exception to the series C requirement. With RSLogix 5000 software, version 11, use it as a generic
1734 module. With RSLogix 5000 software, version 12 or later, it is directly supported.

POINT I/O Modules support the Unsigned Integer data type UINT (0…65,535 range).
RSLogix 5000 software supports the signed Integer data type INT (-32,768 …+32,767 range).
To enter Filter values from +32,768…+65,535 µs, use this conversion formula:
Desired Filter Value (in µs) - 65536 = Entered Filter Value (in µs).
As an example, for a 40 ms filter time, 40000 - 65536 = -25536

To enter values from +128…+255, use these conversion formulas:
Desired Decimal Position Value - 256 = Entered Decimal Position
Value.
As an example, for a divisor of 200, 200 - 256 = -56
Desired Gate Interval Value - 256 = Entered Gate Interval Value.
As an example, for a Gate Interval of 200, 200 - 256 = -56
Desired Scalar Value - 256 = Entered Scalar Value.
As an example, for a Scalar of 128, 128 - 256 = -128

Stored Data
To interpret values from -2,147,483,648 to -1, use this conversion formula:
Stored Data Tag Value + 4,294,967,296 = Actual Stored Data Tag Value.
As an example, for a read value of -1,794,967,296:
-1,794,967,296 + 4,294,967,296 = 2,500,000,000 actual value
Program Fault
Programming Fault Error bit – If an incomplete, incorrect, or conflicting set of configuration parameters is sent to the module, the Program Fault bit will be asserted and an error code will be placed in the Programming Error Code word (assembly 6816). The module will not enter a normal operational state.
Bit definitions (decimal) for the error codes are:
10 An invalid assembly was chosen for poll consumption (0, 105,
or 106 are valid).

Appendix
D
Quick Start
What This Appendix
Contains
In this quick start, you learn how to use the 1734-AENT adapter with a
ControlLogix controller for EtherNet/IP systems.
IMPORTANT
This quick start contains a simple set of steps and reminders that will help you avoid errors when you are configuring your POINT I/O system for and
EtherNet/IP network.
ATTENTION
You must use series C POINT I/O modules with the
1734-AENT adapter. Series A or B POINT I/O modules will not work with this adapter.
Necessary Prerequisites
Before you begin this quick start, make sure the following conditions are in place.
• The ControlLogix controller and RSLogix software version must be version 11 or later.
• The 1756-ENBT module must be revision 2.3 or later.
• The 1734 POINT I/O modules must be series C (except for the
1734-232ASC modules, which can be series A).
• The recommended RPIs are being used: Digital = 10 ms or higher,
Analog and Specialty = 50 ms or higher.
• The 1734-AENT POINT I/O adapter is a child to a local 1756-ENBT module.
131 Publication 1734-UM011D-EN-P - May 2011
132 Quick Start
Configure the Adapter
In the 1734-AENT Module Properties dialog, perform the following steps.
1. Complete the Name field.
2. Enter the following address into the IP Address field: 192.168.1.42
You are setting the last digit, because the first three digits are set for you as set by the push wheel switches on the adapter. The push wheel switches should be set to 042.
3. From the Comm Format menu, choose None if you do not want a rack-optimized connection, or choose Rack Optimization if you want a rack-optimized connection.
4. For the Electronic Keying field, select Compatible Module.
5. Enter the Chassis Size.
Regarding chassis size, the POINT I/O adapter itself takes up a count in the chassis. The default chassis size for the POINT I/O is 1, which covers the adapter only and allows for no I/O. To configure your
POINTBus modules, set the chassis size to the physical amount of your
I/O modules plus one for the adapter; otherwise, you get an error. For example, if you have six modules in the chassis, you must set chassis to
6+1=7.
6. Enter the Slot.
For the adapter itself, the slot number is always 0 and cannot be modified.
7. Click Finish.
Your I/O Configuration tree now looks similar to the following:
Publication 1734-UM011D-EN-P - May 2011
Enter Adapter Properties
Use this procedure to enter adapter properties.
1. Right-click the 1734-AENT adapter and select Properties.
The Module Properties dialog appears.
Quick Start 133
2. Click the Chassis Size tab.
Notice that the data under this tab is dimmed while offline. Use the
Chassis Size tab to send the module size from the General tab to the module itself once you are online. Otherwise, you get an error. We explore this later. For now, click OK to close this dialog:
3. Right-click the POINT I/O adapter under I/O Configuration to add a new module.
4. Select the module from the list and click OK.
Publication 1734-UM011D-EN-P - May 2011
134 Quick Start
5. In the Module Properties dialog, enter the following information.
a. Name b. Slot c. Comm Format d. Electronic Keying, choose Compatible Module to verify the major revision C, because only series C modules support EtherNet/IP.
e. Click Next on the bottom of the dialog.
f. Set the RPI to 10 ms for digital and 50 ms for analog or specialty.
6. Click Finish.
Add Another Module Under the Adapter
Use this procedure to add another module under the adapter.
1. Right-click the POINT I/O adapter under I/O configuration to add a new module.
Your second module is in slot 2.
2. Select the module from the Module Type list, and click OK.
3. In the Module Properties dialog, enter the following information: a. Name b. Slot c. Comm Format d. Electronic Keying, choose Compatible Module.
e. Click Next. f. Set the RPI to 10 ms for digital and 50 ms for analog or specialty.
4. Click Finish.
Continue to add modules to the adapter in this fashion until you have added all of the POINT I/O modules connected to the 1734-AENT adapter to the I/O Configuration tree.
Publication 1734-UM011D-EN-P - May 2011
Quick Start 135
Configure 1734 POINT I/O
Modules
For RSLogix 5000 software version 13 and earlier, configure your POINT I/O modules via the Controller Tags database, using the following steps. For
RSLogix 5000 software, versions 15 or later, the preferred method for module configuration is to use the Module Properties dialog for each POINT I/O module, as described in the individual user manual for the module.
1. Double-click the Controller Tags in the project dialog.
Look at the bottom of the screen to make sure you are in the Monitor
Tags tab.
We are going to assume there is an analog input module 1734-IE2V, which resides in slot 6. We configure Channel 0 of this module to operate over the range -10…+10V DC.
2. Click the configuration tag remote_POINT_IO:3:C.
From here you can set the module configuration and alarms.
In this configuration dialog, you enter the values that would correspond to the desired range. The range type default value for a 1734-IE2V module is 2, which is equal to 0…10V DC.
3. Click the configuration tag for the module in slot 4, remote_POINT_IO:3:Ch0RangeType.
4. Check the value in the tag remote_POINT_IO:3:C.Ch0RangeType.
It is set to 2, which is the default value. There are two settings that this module supports:
Publication 1734-UM011D-EN-P - May 2011
136 Quick Start
• 2 = 0…10V DC
• 0 = -10…+10V DC
Publication 1734-UM011D-EN-P - May 2011
5. Click the value 2 and change it to 0, which changes the voltage range to
-10…+10V DC for channel 0.
Note the following:
• The controller sends the configuration data only when connection is being established.
• Should you need to modify any of the tag values once you change the tag, you need to access the updated information and download it into the module. These are the ways to download the updated configuration information into the module.
– Ideally, you enter the correct code number in the Range Type field at the same time that you add the I/O to the I/O Configuration tree.
You then download later .
Quick Start 137
– If you downloaded the offline configuration into the module and then realize that you must modify any of the module’s configuration parameters, then the preferred way to make these changes online is to go to the Module Connection tab and inhibit the module, apply the changes, and then uninhibit the module. Doing this breaks the connection, causing the configuration information to be downloaded right after the connection is made.
IMPORTANT
Switching the controller from Program to Run mode does not change the module connection status and does not re-send module configuration data.
We highly recommend that you use the inhibit/uninhibit process and avoid power cycling.
6. Right-click the 1734-AENT adapter and select Properties.
7. Click the Connection tab.
You see the following message:
The module is faulted because, even though you set up the adapters
POINT I/O chassis size to the actual number of the modules plus the adapter, the adapter still remembers the size of 1 (the factory default value) until you reset this size manually. This option is available only online.
8. Click the Chassis Size tab.
9. Click the Set Chassis Size in Module button and set the chassis size in the adapter.
Remember to inhibit and unhibit the module for this to take effect.
Publication 1734-UM011D-EN-P - May 2011
138 Quick Start
Now you can put your controller in Run mode, and the connection should be successful.
IMPORTANT
The information found in the Controller Tag Reference section of this user manual is also available in the
RSLogix 5000 online help file. Use the Help file search function under the 1734 catalog number that you are configuring and select the Module Defined Data Types option. You see all of the configurable parameters and associated values.

When a network or device is collapsed, as indicated by the + sign, you can click the + sign or double-click the network or device icon to expand the view and begin browsing. When a network or device is expanded, as indicated by the - sign, you can click the - sign or double-click the network or device icon to collapse the view. The right pane of the
RSWho display is the List Control, which is a graphical representation of all of the devices present on the network.
If there is a communication status error with a device (for example, when a recognized device is inadvertently unplugged), that device appears with a red X, indicating that RSWho previously recognized it, but now it cannot.
You can choose to remove the device from the RSWho display, or you can choose to correct the communication error.
