• Support of connections from multiple controllers simultaneously

What the Adapter Does

You must use RSLogix 5000 to configure these features. For more details on configuration, see Configuration Requirements

in Chapter 3.

The I/O adapters perform the following primary tasks:

• Control of real-time I/O data (also known as implicit messaging) - the

adapter serves as a bridge between I/O modules and the network

• Support of messaging data for configuration and programming

information (also known as explicit messaging)

Chapter 1 Overview of the 1734 POINT I/O EtherNet/IP Adapter

Important Adapter Considerations

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

Set the Chassis Size

The I/O adapters for EtherNet/IP 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, a POINT I/O system consisting of a 1734-AENT adapter, one 1734-IB8, one 1734-OB8, and one 1734-OB8S POINT Guard 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.

Overview of the 1734 POINT I/O EtherNet/IP Adapter Chapter 1

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 POINT I/O modules are present.

Empty Slots and RIUP Situations

The POINT 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.

– 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.

– When you remove a module, the adapter detects 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 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.

Use of the Common Industrial Protocol (CIP)

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.

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.

Overview of the 1734 POINT I/O EtherNet/IP Adapter Chapter 1

Understand the Producer/ Consumer Model

Specify the Requested Packet Interval (RPI)

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.

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 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 adapters 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.

Rockwell Automation Publication 1734-UM018B-EN-P - October 2013 7

Chapter 1 Overview of the 1734 POINT I/O EtherNet/IP Adapter

IMPORTANT

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.

Before You Begin

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

, for more information on connections.

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.

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.

Overview of the 1734 POINT I/O EtherNet/IP Adapter Chapter 1

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 does not reply to the request, the adapter responds with an error code indicating a timeout.

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.

In this chapter, you were introduced to the features of the POINT I/O Adapter, and considerations for its installation and usage.

Replace An Adapter

Use these procedures to install a replacement POINT I/O adapter to an existing system.

1. Disconnect the Ethernet connector(s) from the adapter.

2. Pull up on the Removable Terminal Block (RTB) handle to remove the

terminal block.

3. Remove the adjacent module from its mounting base.

4. Use a small bladed screwdriver to rotate the DIN rail locking screw

(orange) to a vertical position. This releases the locking mechanism.

5. Lift the adapter straight up to remove.

6. Slide the safety end cap up to remove it, which exposes the backplane and

power connections.

ATTENTION: Do not discard the end cap. Use this end cap to cover the exposed interconnections on the last mounting base on the DIN rail. Failure to do so could result in equipment damage or injury from electric shock.

WARNING: When you insert or remove the module while backplane 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. Repeated electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance that can affect module operation.

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 thumbwheel switches.

• Have your network administrator configure the adapter via the network

EXAMPLE

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

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

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.
