Term	Definition
BootP	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.
Bridge	A node between two similar communication subnets where protocol
	translation is minimal.
CIP	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.
Connection	The communication mechanism from the controller to another
	module in the control system, usually used to exchange I/O data.
Consumer	A destination device in the CIP networking model. See CIP.

Publication 1734-UM011D-EN-P - May 2011

viii Preface

Term	Definition
CSMA/CD	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.
Determinism	The ability to predict wheninformation will be delivered. Importantin
	time-critical applications.
DHCP	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 asthe subnet mask
	and default router, and to provide other configuration information,
	such as the addresses for printer, time, and news servers.
	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.
DNS	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	A physical layer standard using carrier sense multiple access with
	collision detection (CSMA/CD) methods.
EtherNet/IP	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	A mode of communication that allows a device to send and receive
	information at the same time, effectively doubling the bandwidth.
Fully qualified	A fully qualifieddomain name (FQDN) is a domain namethat includes
domain name	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.
Gateway	A module or set of modules that allows communications between
	nodes on dissimilar networks.

Publication 1734-UM011D-EN-P - May 2011

Preface ix

Term	Definition
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	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 thatcomputer 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.
	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.
Hub	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 aretime-critical applications that cannot tolerate
	lost packets.
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 betweenthem. Each
	node on the network must have a unique IP address.
Latency	The time between initiating a request for data and the beginning of
	the actual data transfer.
Multicast	In the CIP producer/consumer model, one producer multicasts
	(broadcasts) the data once to all the consumers.
Producer	The source of information in the CIP networking model. See CIP.
Rack-optimized	A physical and logical collection of application modules.
Subnet mask	An extension of the IP address that allows a site to use a single net
	ID for multiple networks.
Switch	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.
TCP	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.

Publication 1734-UM011D-EN-P - May 2011

xPreface

Term	Definition
TCP/IP	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.
Transaction	An exchange of request and data and response and data.
UDP	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

				You must use series C POINT I/O modules with the
	ATTENTION
				1734-AENT adapter. Series A or B POINT I/O modules will
				not work with this adapter.

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

2About 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.

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:

Publication 1734-UM011D-EN-P - May 2011

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.

Publication 1734-UM011D-EN-P - May 2011

4About the Adapter

Cycle Power To a System for the First Time

Adapter Features

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

What the Adapter Does

Use of the Common

Industrial Protocol (CIP)

The 1734-AENT adapter performs the following primary tasks:

•Control of real-time I/O data (also known as implicit messaging) – the 1734-AENT adapter serves as a bridge between POINT I/O modules and the network

	T				T

•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

6About the Adapter

Understand 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 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.

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.

		Although rack-optimized connections offer an efficient
	IMPORTANT
		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

8About 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.
