What the Adapter Does

Use of the Control and Information Protocol (CIP)

The 1794-AENTR and 1794-AENTRXT adapters perform two primary tasks:

• Control of real time I/O data (implicit messaging). The adapter serves as a

bridge between I/O modules and the network.

• Support of messaging data for configuration and programming

information(explicit messaging).

The 1794-AENTR and 1794-AENTRXT adapters use 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.

This has two 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.

Understanding the Producer/Consumer Model

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.

Publication 1794-UM066A-EN-P - February 2012

4 Overview of FLEX I/O and Your Redundant EtherNet/IP Adapter Module

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 producer/consumer model.

Specifying the Requested Packet Interval (RPI)

Support of Rack Optimized and Direct Connections

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 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.

The 1794-AENTR and 1794-AENTRXT adapters support 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.

Publication 1794-UM066A-EN-P - February 2012

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 have set up a system that contains 8 discrete 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 8 connections to transfer all of the data, one to each of

IMPORTANT

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 adapter.

Refer to the EtherNet/IP Embedded Switch Technology Application Guide, publication number ENET-AP005

Mixing Rack Optimized and Direct Connections

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

• You can only use rack optimized connections to send data to and

from discrete I/O modules. Analog I/O requires direct connections.

• Rack optimized connections can contain I/O data and status

information only. Additional module information, such as diagnostics, is not available through a rack-optimized connection.

• All data is sent at the same time at the RPI rate of the adapter.

, for more information on connections.

Chapter Summary

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 requested packet interval (RPI) configured for the 1794-AENTR or 1794-AENTRXT adapter. I/O modules configured for direct communication will communicate at their own set RPIs and ignore the adapter RPI.

This chapter briefly described the FLEX I/O system, the FLEX I/O dual port EtherNet/IP adapters, and the basic adapter features. Read the next chapter to learn how to physically install the adapters and connect them to the EtherNet/IP network.

Mount Your Adapter on a DIN Rail

Follow these steps to mount the adapter on a new system before installing any I/O modules.

ATTENTION: During mounting of all devices, be sure that all debris (for example, metal chips, wire strands) is kept from falling into the module. Debris that falls into the module could cause damage on power up.

ATTENTION: Do not remove or replace an Adapter Module while power is applied. Interruption of the backplane can result in unintentional operation or machine motion.

1. Position the adapter module (A) on an IEC standard (35 x 7.5 x 1 mm) top-hat DIN rail (B) at a slight angle (DIN rail: Allen-Bradley part number 199-DR1; 46277-3; EN50022).

2. Hook the lip on the rear of the adapter onto the top of the DIN rail, and pivot the adapter module onto the rail.

3. Press the adapter module down onto the DIN rail until flush. Locking tab (C) snaps the adapter into position and locks it onto the DIN rail.

4. If the adapter module does not lock in place, use a screwdriver or similar device to move the locking tab down while pressing the adapter module flush onto the DIN rail, and release the locking tab to lock the adapter module in place. If necessary, push up on the locking tab to lock.

5. Connect the adapter wiring as shown in the Connect Wiring diagram.

4. Connect +24V DC input power to the left side of the lower connector, terminal C.

5. Use connections D and E to pass +24V DC common (E) and 24V DC power (D) to the next module in the series (if required).

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 on the module.

• Use a Dynamic Host Configuration Protocol (DHCP) server, such as Rockwell Automation DHCP.

• Retrieve the IP address (if previously set) from nonvolatile memory.

The adapter reads the thumbwheel switches first to determine if the switches are set to a valid number. You set the node address by using the three-position thumbwheel switch. Press the + or - buttons to change the number. Valid settings are 001…254.

When the switches are set to a valid number, the adapter IP address is

192.168.1.xxx (where xxx represents the number set on the switches). The adapter subnet mask is 255.255.255.0 and the gateway address is set to 0.0.0.0. The adapter does not have a host name assigned, or use any Domain Name System when using the thumbwheel settings.

If you set the switches to an invalid number (such as 000, or a value greater than

254), the adapter checks to see if you enabled DHCP.

Overview

Configuration Requirements

This chapter describes how to configure the 1794-AENTR or 1794-AENTRXT adapter module for the ControlLogix system.

Topic Page

Configuration Requirements IP Address Gateway Address Subnet Mask Use the Rockwell BootP/DHCP Utility Configure Your Adapter using DHCP Software

Before you can use your 1794-AENTR or 1794-AENTRXT adapter, you must configure its IP address, and optionally, its subnet mask and gateway address. You can use the Rockwell BootP/DHCP utility to perform the configuration. You can also use generic BootP software or, within some limitations, a DHCP server.

When using the BootP protocol, you must enter the Ethernet hardware address of your adapter. Rockwell assigns each 1794-AENTR or 1794-AENTRXT adapter a unique 48-bit hardware address at the factory. The address is printed on a label on the front of your 1794-AENTR or 1794-AENTRXT adapter. 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 1794-AENTR or 1794-AENTRXT 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 1794-AENTR or 1794-AENTRXT adapter) must have a unique IP address.

Net ID

Host ID

1 1 0

EXAMPLE

TIP

The IP address is 32 bits long and has a Net ID part and a 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:

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.

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.

Contact your network administrator or the Network Information Center for a unique fixed IP address to assign to your module.

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. When a node needs to communicate with a node on another network, a gateway transfers the data between the two

These two bits of the host ID used to extend the net ID

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 then resolves C’s IP address into a hardware address (MAC address) and communicates 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.

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 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.

Take Network 2 (a Class B network) in the previous example and add another network. Selecting the following subnet mask would add two additional net ID bits, allowing for four logical networks:

Two bits of the Class B host ID have been 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 logical network.

The new configuration is:

Use the Rockwell BootP/DHCP Utility

A second network with Hosts D and E was added. Gateway G2 connects Network 2.1 with Network 2.2. Hosts D and E use Gateway G2 to communicate with hosts not on Network 2.2. Hosts B and C use Gateway G to communicate with hosts not on Network 2.1. When B is communicating with D, G (the configured gateway for B) routes the data from B to D through G2.

The Rockwell BootP/DHCP utility is a stand alone program that incorporates the functionality of standard BootP/DHCP software with a user-friendly graphical interface. It is located in the Utils directory on the RSLogix 5000 installation CD. The module must have DHCP enabled (factory default and the network address switches set to an illegal value) to use the utility.

To configure your module using the BootP/DHCP utility, perform the following steps:

1. Run the BootP/DHCP software.

The BOOTP/DHCP Request History dialog appears showing the hardware addresses of devices issuing BootP/DHCP requests.

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

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

3. Enter the IP Address you want to assign to the device and click OK.

TIP

The device is added to the Relation List, displaying the Ethernet Address (MAC) and corresponding IP Address, Hostname and Description (if applicable).

When the IP address assignment is made, the address displays in the IP Address column in the Request History section.

4. To assign this configuration to the device, highlight the device in the Relation List panel and click Disable BOOTP/DHCP. When power is cycled to the device, it uses the configuration you assigned and not does not issue a DHCP request.

To enable DHCP for a device that has had DHCP disabled, highlight the device in the Relation List and click Enable DHCP. You must have an entry for the device in the Relation List panel to re-enable DHCP.

Publication 1794-UM066A-EN-P - February 2012

Save the Relation List

You can save the Relation List to use later. To save the Relation List do the following:

1. Select Save As... from the File menu.

Configure Your Adapter using DHCP Software

The Save As dialog box appears.

2. Select the folder you want to save the list to.

3. Enter a file name for the Relation List (for example, control system

configuration) and click Save.

If you want to see your saved file names in the Open dialog box, save your files using the default file type (*.bpc).

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

Publication 1794-UM066A-EN-P - February 2012

22 Configure the Adapter for Your EtherNet/IP Network

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-AENTR or 1794-AENTRXT 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. Check with your system administrator to see if your DHCP package supports BootP commands and manual IP allocation.

ATTENTION: The 1794-AENTR or 1794-AENTRXT 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.

This chapter described how to set up and use rack optimized discrete I/O. The next chapter describes how to add analog I/O modules to a configuration using direct connection.

Chapter

Analog I/O with Direct Connection

Overview

In this example you add analog input and output modules to the FLEX I/O configured with two digital I/O modules in the previous chapter. Analog modules default to direct connection, so you will open a direct connection to each analog module while still using a single rack optimized connection for the two digital I/O modules.

To test the system, the example of the previous chapter is modified to send a signal to one of the analog output channels and read the signal back in through one of the analog input channels.
