About This User Manual P-5
Terminology
This term
Means
bandwidth
The transmission capacity of the network, expressed in bits per second. Traditional Ethernet has a 10Mbit bandwidth. Fast Ethernet is 100Mbit.
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 CIP
The 1794-AENT factory default is BootP enabled. Upon powerup, the module sends a message containing its hardware address to
n the BootP server on the network. The server is a computer with
BootP server software installed. The server compares that
.c hardware address to those in its lookup table in the
configuration file and sends a message back to the module with the appropriate IP address.
ia A node between two similar communication subnets where b protocol translation is minimal.
Control and Information Protocol, the EtherNet/IP application
m layer. CIP uses the "producer/consumer" networking model. In
this model one producer broadcasts (multicasts) the data once to
a all the consumers. All consumers see the data simultaneously, cand may choose whether to consume (receive) the data or not.
@ consumer s CSMA/CD il: sale determinism Ema DHCP
Delivery time is consistent, no matter how many consumers there are.
A destination device in the CIP networking model. See CIP.
Carrier Sense Multiple Access/Collision Detection. 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 (DHCP) 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 Domain Name System (DNS) 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.

P-6 About This User Manual
This term
Means
Ethernet network
A local area network designed for the high-speed exchange of information between computers and related devices.
EtherNet/IP
Ethernet Industrial Protocol. EtherNet/IP applies a common application layer (CIP) over Ethernet by encapsulating messages in TCP/UDP/IP.
explicit messaging
Non-time critical messaging used for device configuration and
data collection, such as downloading programs or peer-to-peer
messaging between two PLCs.
fast Ethernet full duplex
fully qualified domain name
Ethernet operating at 100Mbps/second.
n A mode of communication that allows a device to send and
receive information at the same time, effectively doubling the
.c bandwidth.
A Fully Qualified Domain Name (FQDN) is a domain name that
ia includes all higher level domains relevant to the entity named. If
you think of the DNS as a tree-structure with each node having
b 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
m FQDN would include the string that identifies the particular host,
plus all domains of which the host is a part up to and including
a the top-level domain (the root domain is always null). For cexample, PARIS.NISC.SRI.COM is a Fully Qualified Domain
gateway
s@ host name Email: sale hub
Name for the host at 192.33.33.109.
A module or set of modules that allows communications between nodes on dissimilar networks.
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 the foobar website is www.foobar.com. The Host Name is "www", which is not unique on the web, but is unique within the foobar domain.
The Host Name can also refer to the Fully Qualified Domain Name, or in this example, www.foobar.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.foobar.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.
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.
Publication 1794-UM006A-EN-P - July 2001
About This User Manual P-7
This term
Means
IP address
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 periods between them. Each node on the network must have a unique IP address.

ma Use of the Control and E Information Protocol (CIP)
The 1794-AENT adapter uses the Control and Information Protocol (CIP). CIP is the application layer protocol specified for EtherNet/IP, the Ethernet Industrial Protocol, as well as for ControlNet and
DeviceNet. 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.
Publication 1794-UM006A-EN-P - July 2001
About the 1794-AENT Adapter 1-3
This has two significant benefits:
1. You do not need to configure routing tables in the bridging modules, which greatly simplifies maintenance and module replacement.
2. You maintain full control over the route taken by each message,
which enables you to select alternative paths for the same end
device.
Understanding the Producer/Consumer Model
n The CIP "producer/consumer" networking model replaces the old .c source/destination ("master/slave") model. The producer/consumer
model reduces network traffic and increases speed of transmission. In
ia traditional I/O systems, controllers poll input modules to obtain their
input status. In the CIP system input modules are not polled by a
b controller. Instead, they produce ("multicast") their data either upon a
change of state (COS) or periodically. The frequency of update
m depends upon the options chosen during configuration and where on
the network the input module resides. The input module, therefore, is
ca 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
@ over the EtherNet/IP network. This data exchange conforms to the s producer/consumer model.
ale Specifying the Requested Email: s Packet Interval (RPI)
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 50ms, it means that every 50ms the device should send its data to the controller or the controller
should send its data to the device.
RPIs are only used for devices that produce 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; it is used only as a bridge to remote racks.

1-4 About the 1794-AENT Adapter
Support of Rack Optimized and Direct Connections
The 1794-AENT adapter supports both direct and rack optimized connections. A direct connection is a "real-time" data transfer link between the controller and the device 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.
n The following example illustrates the benefit of rack optimized
connections.
.c Assume you have set up a system that contains 8 discrete I/O modules ia interfaced to a 1794-AENT adapter. If you use direct connections to
transfer data to each of the these I/O modules, you need 8
b 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,
m you only need a single connection the connection to the 1794-AENT ca adapter.
@ IMPORTANT
Although rack optimized connections offer an efficient way to use resources, there are a few limitations on their use:
les· You can only use rack optimized connections to send data to and from discrete I/O modules.
a Analog I/O requires direct connections.
s · Rack optimized connections can contain I/O data il: and status information only. Additional module
information, such as diagnostics, is not available through a rack-optimized connection.
a · All data is sent at the same time at the RPI rate of Em the 1794-AENT adapter.
See the EtherNet/IP Performance and Application Guide, publication number ENET-AP001, for more information on connections.

About the 1794-AENT Adapter 1-5
Mixing 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 will communicate at the rate of the RPI (requested packet interval) configured for the 1794-AENT adapter. I/O modules configured for direct communication will communicate at their own set RPIs and ignore the 1794-AENT adapter's RPI.

Configuration Requirements
Before you can use your 1794-AENT adapter, you must configure its IP address, and optionally, its subnet mask and gateway address. You can use the Rockwell BootP utility to perform the configuration. You can also use generic BootP software or, within some limitations, a DHCP server.
IMPORTANT When using the BootP protocol, you must enter the Ethernet hardware address of your adapter. Rockwell
Ethernet Address (MAC)
assigns each 1794-AENT adapter a unique 48-bit hardware address at the factory. The address is printed on a label on the front of your 1794-AENT
n adapter as shown in the figure at left. It consists of .c six hexadecimal digits separated by colons. This
address is fixed by the hardware and cannot be
ia changed.
If you change or replace the 1794-AENT adapter, you
b must enter the new Ethernet hardware address of the cam adapter when you configure the new adapter.
IP Address
@ The IP address identifies each node on the IP network (or system of s connected networks). Each TCP/IP node on a network (including the le 1794-AENT adapter) must have a unique IP address. aThe IP address is 32 bits long and has a Net ID part and a Host ID spart. Networks are classified A, B, C, (or other). The class of the
network determines how an IP address is formatted.

Publication 1794-UM006A-EN-P - July 2001
Configuring the 1794-AENT Adapter for Your EtherNet/IP Network 3-3
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:
n 10000000 00000001 00000000 00000001 is written as 128.1.0.1.
.c TIP
Contact your network administrator or the
Network Information Center for a unique fixed IP
ia address to assign to your module.
b Tip
cam Gateway Address
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.
s When a node needs to communicate with a node on another network, le a gateway transfers the data between the two networks. The following
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.

3-4 Configuring the 1794-AENT Adapter for Your EtherNet/IP Network
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 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
BootP client, such as the 1794-AENT adapter, can boot from a DHCP
server only if the DHCP server is specifically written to also handle BootP queries. This is specific to the DHCP software package you use.
n Check with your system administrator to see if your DHCP package
supports BootP commands and manual IP allocation.
! cambia.c ATTENTION
The 1794-AENT adapter must be assigned a fixed network address. The IP address of this adapter must not be dynamically provided.
Failure to observe this precaution may result in unintended machine motion or loss of process control.

About the Example
In this example you add analog input and output modules to the
