Chapter 1 Overview of the 1738 ArmorPOINT I/O EtherNet/IP Adapter

Important Adapter

Considerations

Before you begin using your adapter, note the following important

considerations.

Set the Chassis Size

The ArmorPOINT I/O adapters require configuration of their chassis size before

you can make any I/O connections. The factory default setting for the chassis size

is one slot, which represents the adapter by itself.

You must set the chassis size to a number equaling one slot for the adapter plus

one slot for each I/O module present in the backplane of the adapter.

For example, an ArmorPOINT I/O system consisting of a 1738-AENT adapter,

one 1738-IB8, one 1738-OB8, and one 1738-OB8S POINTGuard I/O module

uses a chassis size of 4. The adapter stores this chassis size setting in non-volatile

memory.

Each time the adapter is powered up, the adapter compares the number of I/O

modules present on its backplane to the chassis size value from non-volatile

memory. The adapter does not allow any I/O connection until the number of

I/O modules present equals the chassis size value minus one for the adapter itself.

Adapter

Replacement

Note that during a connection request from the controller, the chassis size setting

is not communicated to the adapter. You must always set this chassis size using a

separate operation. This includes situations when you are replacing an adapter.

The adapter does not allow any I/O connections until it is configured with the

appropriate chassis size and the proper number of ArmorPOINT I/O modules

are present.

Empty Slots and RIUP Situations

The ArmorPOINT I/O system cannot detect an empty terminal base. For this

reason, there are numerous situations in which you can potentially configure a

system that is unusable or one that exercises unintended control.

In an attempt to address these situations, you must observe the following rules for

I/O system construction and the

removal and reinsertion of modules.

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

• After you cycle power, the adapter will not allow any I/O connections

until the number of modules comprising the chassis plus one for the

adapter equals the stored chassis size.

Rockwell Automation Publication 1738-UM005A-EN-P - July 2013 5

Overview of the 1738 ArmorPOINT I/O EtherNet/IP Adapter Chapter 1

– It cannot assume any safe operation until there is a match between the

number of modules indicating their presence in the chassis and what the

adapter has saved in non-volatile memory because it cannot detect

empty terminal bases.

– Actual module identification (such as, electronic keying) is done when

connection establishment requests are received from the controller or

controllers.

• A POINT I/O module removed under power does not disrupt operation

of the other I/O modules. On the other hand, ArmorPOINT I/O

modules are not intended to be removed under power.

• 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 correct data once they pass their electronic keying

check.

• These removal and return situations exist whether the system is under

power or not. If the system is under power, the situation arises immediately.

If the system is not under power, the situation arises in the next power

cycle.

Power Up a System for the First Time

When you power the I/O for the first time, the adapter must assign slot addresses

to every module in the backplane. All I/O modules ship configured at the same

address.

When you first apply power, we expect that all but one module on the backplane

exhibits a solid red Module Status 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

I/O system.

6 Rockwell Automation Publication 1738-UM005A-EN-P - July 2013

Chapter 1 Overview of the 1738 ArmorPOINT I/O EtherNet/IP Adapter

Use of the Common

Industrial Protocol (CIP)

The adapter uses the Common Industrial Protocol (CIP). CIP is the application

layer protocol specified for EtherNet/IP, the Ethernet Industrial Protocol, as well

as for ControlNet and DeviceNet networks. It is a message-based protocol that

implements a relative path to send a message from the producing device in a

system to the consuming devices.

The producing device contains the path information that steers the message along

the proper route to reach its consumers. Since the producing device holds this

information, other devices along the path simply pass this information; they do

not store it.

This has the following significant benefits:

• You do not need to configure routing tables in the bridging modules,

which greatly simplifies maintenance and module replacement.

• You maintain full control over the route taken by each message, which

enables you to select alternative paths for the same end device.

Understand the Producer/

Consumer Model

The CIP producer and consumer networking model replaces the old source and

destination (master and slave) model. The producer and consumer model reduces

network traffic and increases speed of transmission. In traditional I/O systems,

controllers poll input modules to obtain their input status. In the CIP system,

input modules are not polled by a controller. Instead, they produce (multicast or

unicast) their data either upon a change of state (COS) or periodically.

Multicast is the default mode for version 17 Logix and earlier controllers and

unicast is the default for version 18 with multicast as a selectable option.

The frequency of update depends upon the options chosen during configuration

and where on the network the input module resides. The input module,

therefore, is a producer of input data, and the controller is a consumer of the data.

The controller also produces data for other controllers to consume. The

produced and consumed data is accessible by multiple controllers and other

devices over the EtherNet/IP network. This data exchange conforms to the

producer and consumer model.

Specify the

Requested

Packet Interval (RPI)

The Requested Packet Interval or RPI is the update rate specified for a particular

piece of data on the network. The RPI can be specified for the adapter and

include all of the I/O modules in the I/O system (using a rack-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

Rockwell Automation Publication 1738-UM005A-EN-P - July 2013 7

Overview of the 1738 ArmorPOINT I/O EtherNet/IP Adapter Chapter 1

every 50 ms the device should send its data to the controller and the controller

should send the consumed (output) data to the device.

Use RPIs only for devices that exchange data. For example, a ControlLogix

EtherNet/IP bridge 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.

Support for Rack-optimized

and Direct Connections

The I/O adapter supports both direct and rack-optimized connections. A direct

connection is a real-time data transfer link between the controller and the module

occupying the slot that the configuration data references.

Direct I/O connections occur at a cyclic rate specified by the RPI during

configuration. A rack-optimized connection is a grouping of data from one or

more digital I/O modules into a single block of data sent over a single connection

at the same data rate.

Analog, safety, and speciality modules cannot participate in the rack-optimized

connection; these modules require a direct I/O connection.

Rack-optimized connections reduce the total number of connections needed to

transfer data when using many digital I/O modules in a system. The following

example illustrates the benefit of rack-optimized connections.

Assume you set up a system that contains eight digital I/O modules interfaced to

an adapter. If you use direct connections to transfer data to each of the these I/O

modules, you need eight connections to transfer all of the data, one to each of the

eight I/O modules. If you use a rack-optimized connection to transfer the data,

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

See the EtherNet/IP Embedded Switch Technology Application Guide,,

publication ENET-AP005

, for more information on connections.

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 I/O adapters.

If the update rate required for a digital module is different from the

RPI of the rack-optimized connection, a direct connection to that

digital I/O module is required.

8 Rockwell Automation Publication 1738-UM005A-EN-P - July 2013

Chapter 1 Overview of the 1738 ArmorPOINT I/O EtherNet/IP Adapter

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

communicate at the rate of the RPI configured for the adapter. I/O modules

configured for direct communication communicate at their own individual RPIs

and ignore the rack-optimized RPI.

Chapter

Configure the Adapter with RSLogix5000

software

Introduction

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

using the RSLogix 5000 software. Note that the modules presented in this

chapter can be configured using RSLogix 5000 software, version 17, or later.

Before using your adapter in an EtherNet/IP network, you need to configure it

with an IP address, subnet mask, and optional Gateway address. This chapter

describes these configuration requirements and the procedures for providing

them. Here are ways you can do this:

• Use the Rockwell BootP/DHCP utility, version 2.3 or later, that ships

with RSLogix 5000 or RSLinx software.

– You can also use this utility to reconfigure a device with an IP address

you must change.

• Use a

third party DHCP server.

• Use the Network Address rotary switches.

• Have your network administrator configure the adapter via the network

DHCP server.

See the table for where to find information in this chapter.

Chapter 3 Configure the Adapter with RSLogix5000 software

Configuration

Requirements

Before you can use your adapter, you must configure its IP address, its subnet

mask, and, optionally, a gateway address. You can use the Rockwell BootP utility,

version 2.3 or later, to perform the

configuration. You can also use a DHCP

server or the network address rotary switches to configure these parameters.

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

Configuration Pages on page 92.

IP Address

The IP address identifies each node on the IP network (or system of connected

networks). Each TCP/IP node on a network (including the adapter) must have a

unique IP address.

The IP address is 32 bits long and has a Network ID part and Host ID part.

Networks are classified A, B, C, (or other). The class of the network determines

how an IP address is formatted

You can distinguish the class of the IP address from the first integer in its dotted-

decimal IP address as follows:

Each node on the same physical network must have an IP address of the same

class and must have the same network ID. Each node on the same network must

have a different Host ID thus giving it a unique IP address.

IMPORTANT

If using the BootP/DHCP utility, you will need to know the Ethernet

hardware address of your module. Rockwell assigns each 1738

ArmorPOINT I/O Ethernet/IP Module a unique 48-bit hardware

address at the factory. The address is printed on a label on the side of

your module. 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 1738 ArmorPOINT I/O Ethernet/IP

Module, you must enter the new Ethernet hardware address of the

module when you configure the new module.

Configure the Adapter with RSLogix5000 software Chapter 3

IP addresses are written as four decimal integers (0…255) separated by periods

where each integer gives the value of one byte of the IP address

Gateway Address

This section applies to multi-network systems. If you have a single network

system, refer to the next section.

The Gateway Address is the default address of a network. It provides a single

domain name and point of entry to the site. Gateways connect individual physical

networks into a system of networks.

When a node needs to communicate with a node on another network, a gateway

transfers the data between the two networks. The figure shows gateway G

connecting Network 1 with Network 2.

When host B with IP address 128.2.0.1 communicates with host C, it knows

from C’s IP address that C is on the same network. in an Ethernet environment, B

can then resolve C’s IP address into a hardware address (MAC address) and

communicate with C directly.

When host B communicates with host A, it knows from A’s IP address that A is

on another network (the network IDs are different). In order to send data to A, B

must use the IP address of the gateway connecting the two networks. In this

example, the gateway’s IP address on Network 2 is 128.2.0.3.

The gateway has two IP addresses (128.1.0.2 and 128.2.0.3). The first must be

used by hosts on Network 1 and the second must be used by hosts on Network 2.

To be usable, a gateway of a host must be addressed using a network ID matching

its own.

EXAMPLE

For example, the 32-bit IP address:

10000000 00000001 00000000 00000001 is written as

128.1.0.1

Network 1

Network 2

128.1.0.1

128.2.0.1 128.2.0.2 128.2.0.3

128.1.0.2

16 Rockwell Automation Publication 1738-UM005A-EN-P - July 2013

Chapter 3 Configure the Adapter with RSLogix5000 software

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

Two bits of the Class B host ID are used to extend the network ID. Each unique

combination of bits in the part of the Host ID where subnet mask bits are 1

specifies a different physical network.

The new configuration is:

A second network with Hosts D and E was added. Gateway G2 connects

Network 2.1 with Network 2.2.

Hosts D and E will use Gateway G2 to communicate with hosts not on

Network 2.2.

Hosts B and C will use Gateway G to communicate with hosts not on

Network 2.1.

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

the data from B to D through G2.

EXAMPLE

Take Network 2 (a Class B network) in the previous

example and add another physical network. Selecting the

following subnet mask would add two additional

network ID bits, allowing for four physical networks:

11111111 11111111 11

000000 00000000 = 255.255.192.0

These two bits of the Host ID are used to

extend the netdwork ID.

Set the

Network Address

The adapters ship DHCP-enabled and with the switches set to 999. You can set

the network Internet Protocol (IP) address as follows.

Set the Network Address for ArmorPOINT I/O Adapters

• Adjust the rotary switches in front of the module

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

Rockwell Automation BootP/DHCP

• Retrieve the IP address from non-volatile memory

The adapter reads the rotary switches first to determine if they are set to a valid

number. Set the network address by adjusting the three rotary switches on the

front of the adapter.

Figure 1 - Network Address Example

Use a small blade screwdriver to rotate the switches. Line up the small notch on

the switch with the number setting you wish to use. Valid settings range from

001…254.

When you use the switches to assign an address and set it to 001, the adapter

gateway address is set to 0.0.0.0. and the subnet mask is 255.255.255.0 . When

you use the switches to assign an address and set it to a valid number between

002...254, the adapter gateway address is set to 192.168.1.1.

If the switches are set to an invalid number (for example, 000 or a value greater

than 254 excluding 888), the adapter checks to see if DHCP is enabled. If DHCP

is enabled, the adapter requests an address from a DHCP server. The DHCP

server also assigns other Transport Control Protocol (TCP) parameters.

If DHCP is not enabled, the adapter uses the IP address, along with other TCP

configurable parameters, stored in non-volatile memory.

WARNING: When you change switch settings while power is on, an

electrical arc can occur. This could cause an explosion in hazardous

location installations.

Be sure that power is removed or the area is nonhazardous before

proceeding.

Chapter 3 Configure the Adapter with RSLogix5000 software

Use the Rockwell BootP/

DHCP Utility

The Rockwell BootP/DHCP utility is a standalone program that incorporates

the functionality of standard BootP software with a user-friendly graphical

interface. It is located in the Ut ils directory on the RSLogix5000 software

installation CD. The adapter must have DHCP enabled (factory default and the

network address switches set to an invalid value) to use the utility.

To configure your adapter using the BootP utility, perform the following steps:

1. Run the BootP software.

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

devices issuing BootP requests.

Rockwell Automation Publication 1738-UM005A-EN-P - July 2013 19

Configure the Adapter with RSLogix5000 software Chapter 3

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

The New Entry dialog appears with the device’s Ethernet Address (MAC).

20 Rockwell Automation Publication 1738-UM005A-EN-P - July 2013

Chapter 3 Configure the Adapter with RSLogix5000 software

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, the IP address assignment has been made.

4. To make this configuration static in the device, highlight the device in the

Relation List panel, and click the Disable BOOTP/DHCP button.

When power is cycled to the device, it uses the configuration saved in non-

volatile memory and will not issue a DHCP request.

5. To enable DHCP for a device with DHCP disabled, highlight the device

in the Relation List, and click the Enable DHCP button.

You must have an entry for the device in the Relation List panel to re-

enable DHCP.
