Terminology

http://www.software.rockwell.com

Refer to the table for the meaning of common terms.

This Term Means

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.

Publication 1734-UM011C-EN-P - January 2006

6 Preface

This Term Means

consumer A destination device in the CIP networking model. See CIP. 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 when information will be delivered. Important in

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 as the 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.

Publication 1734-UM011C-EN-P - Januar y 2006

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 domain name

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.

Preface 7

This Term Means

Gateway A module or set of modules that allows communications between

nodes on dissimilar networks.

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 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 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. 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 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.

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.

Important Adapter

ATTENTION

Before you begin using your adapter, note the following important considerations.

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. The default setting for the chassis size is 1 slot, which represents the adapter by itself.

1 Publication 1734-UM011C-EN-P - January 2006

1-2 About the Adapter

You must set the chassis size to a number equ a ling 1 slot for the adapter plus 1 slot for each I/O module present in the adapter’s 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 si tuations 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-UM011C-EN-P - Januar y 2006

About the Adapter 1-3

• A correct POINT I/O system does not have any empty terminal bases.

• After you cycle power , the ad apter will not run any I/O un til 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 prese nce 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 will fail during verification of the electronic ID (providing that keying has not been disabled).

• If modules of the same type are removed and returned to the wrong locations, they accept connections from the controller or controllers and reconfigure with the co rrect data o nce the y 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.

Publication 1734-UM011C-EN-P - January 2006

1-4 About the Adapter

Cycle Power To a System For the First Time

When you power 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 addr esses them appropriately. The amount of time that this operation takes is proportional to the size of your POINT I/O system.

Devices

• 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.

Publication 1734-UM011C-EN-P - January 2006

1-6 About the Adapter

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.

• Y ou maintai n 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

Specify the Requested Packet Interval (RPI)

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).

Publication 1734-UM011C-EN-P - Januar y 2006

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-produ cin g member of the system. Its use is only as a bridge to remote racks.

About the Adapter 1-7

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 co nnection 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 connectio ns 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

See the EtherNet/IP Performance and Application Guide, publication number ENET-AP001, for more information on connections.

Although rack-optimized connections offer an efficient way to use resources, there are a few limitations on their use:

• You can us e on ly 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.

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-UM011C-EN-P - January 2006

1-8 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 d oes no t reply to the request, the adapter responds with an error code indicating a timout.

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 re configure 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.

3-2 Configure the Adapter for Your EtherNet/IP Network

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 parameter s .

If you need to reset the adapter to factory defaults, see the Important note about setting thumbwheels to the value 888.

IP Address

Ethernet Address (MAC)

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 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 comp lete.

Publication 1734-UM011C-EN-P - Januar y 2006

Configure the Adapter for Your EtherNet/IP Network 3-3

IMPORTANT

If using the BootP/DHCP utility, you need to know the Ethernet hardware address of your adapter. Rockwell 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 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.

Class A

Class B

Class C

Net ID

Host ID

1 0

1 1 0

Net ID

Y ou can di stinguish the class of the IP address from the first integer in its dotted-decimal IP address as follows:

Range of first integer Class Range of first integer Class

0 …127 A 192 … 223 C

128 …191 B 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.

Publication 1734-UM011C-EN-P - January 2006

3-4 Configure the Adapter for Your EtherNet/IP Network

IP addresses are written as four decimal integers (0 to 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.

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.

128.1.0.1

Network 1

128.2.0.1 128.2.0.2

128.1.0.2

128.2.0.3

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.

Publication 1734-UM011C-EN-P - Januar y 2006

Configure the Adapter for Your EtherNet/IP Network 3-5

extend the net ID.

The gateway has two IP addresses (128.1.0.2 and 128.2.0.3). Th e 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 11

000000 00000000 =

255.255.192.0

These two bits of the Host ID are used to

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 netw or k.

Configure the Adapter for Your EtherNet/IP Network 3-7

Set the Network Address

The adapter ships with the thumbwheel switches set to 999 and DHCP enabled. You can set the network Internet Protocol (IP) address in these ways:

• Use the thumbwheel switches located on the module.

• Use a Dynamic Host Configuration Protocol (DHCP) server, such

as Rockwell Automation BootP/DHCP.

• Retrieve the IP address from nonvolatile memory.

Network Address Thumbwheel Press either the + or buttons to change the number.

43248

The adapter reads the thumbwheel switches only when you cycle power to determine if the switches are set to a valid num ber. 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.

Publication 1734-UM011C-EN-P - January 2006

3-8 Configure the Adapter for Your EtherNet/IP Network

Use the Rockwell BootP/DHCP Utility

The Rockwell 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 RSLogix5000 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.

You can leave the Save as type at the default setting: Bootp Config Files (*.bpc).

Use DHCP Software to Configure Your Adapter

You can then open the file containing the Relation List at a later session.

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.

3-12 Configure the Adapter for Your EtherNet/IP Network

Refer to the section Configure the 1734-AENT Adapter with Fixed IP Address in this manual to configure the adapter with a fixed IP address.

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.

Recover From an Overloaded Adapter

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 i nterval (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-UM011C-EN-P - January 2006

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 in clud e 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 Eth ernet adapter

• # = slot number of POINT I/O module

• C = configuration, I = input, O = output

This value indicates that slot 2 is the only module participating in the rack-optimized connection with no errors.

Publication 1734-UM011C-EN-P - January 2006

5-22 Configure the Adapter for Direct Connection and Rack Optimization in RSLogix 5000 Software

Use the controller tags in your ladder program to re ad in put 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

– 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-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)
