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

• 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.

removal and reinsertion of modules.

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

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.

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

Use of the Common Industrial Protocol (CIP)

Understand the Producer/ Consumer Model

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.

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.

Specify the Requested Packet Interval (RPI)

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.

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

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

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

IMPORTANT

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.

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.

See the EtherNet/IP Embedded Switch Technology Application Guide,, publication ENET-AP005

, for more information on connections.

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.

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

• Use the Network Address rotary switches.

• Have your network administrator configure the adapter via the network

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 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.

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 dotteddecimal IP address as follows:

Range of first integer Class Range of first integer Class

0 1…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 network ID. Each node on the same network must have a different Host ID thus giving it a unique IP address.

128.1.0.2

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

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.

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.

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.

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

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.

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

When B is communicating with D, G (the configured Gateway for B) will route the data from B to D through G2.

This example shows the network address set at 163.

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.

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 nonvolatile 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 reenable DHCP.
