Thumbwheel Settings

You can set the thumbwheels on the adapter to perform different functions. Refer to the following table to see the valid thumbwheel settings and the corresponding function.

Setting Function

001...254 Sets the network address.

801...864 Sets the chassis size.

888 Restores default factory settings.

Refer to Set the Network Address on page 24 for more information.

Refer to Set the Chassis Size by Using the Thumbwheels on page 5 information.

for more

If the thumbwheels are set to an invalid number, 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.

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.

Four I/O modules

One adapter

Chassis size = 5

For example, if your system consists of one adapter and four I/O modules, set the chassis size to 5.

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.

You can set the chassis size by using the following:

Set the Chassis Size by Using the Thumbwheels

For firmware revision 5.015 or later, you can set the chassis size without a computer by using the thumbwheels on the adapter.

1. Make sure that the adapter is not powered.

2. Set the thumbwheels to 8xx where xx is the chassis size value from 01...64.

Rockwell Automation Publication 1734-UM018D-EN-E - September 2017 5

TIP

For example, set the thumbwheels to 802 to set the chassis size to 2, 803 to set the chassis size to 3, and so on up to 864 to set the chassis size to 64.

3. Power up the adapter.

4. Observe the status indicators.

The following table describes the status indicators of the adapter when the adapter is powered up while the thumbwheels are set a value from

801...864:

Indicator Status

changes to solid green or continues to flash red depending on the connection result.

• Solid green – if the configured chassis size and number of physical

nodes present match

• Flashing red – if the configured chassis size and number of physical

nodes present do not match

Note: Communication on all Ethernet ports are disabled while the thumbwheels are set to 8xx.

5. If the POINTBus Status indicator changes to solid green, skip to Step 9.

6. If the POINTBus Status indicator continues to flash red, determine the

cause of the error.

The cause of error may be one of the following:

Error Action

Chassis size mismatch

Module fault Refer to the installation instructions publication for the affected module

Make sure that the chassis size value matches the total number of the adapter plus the I/O modules.

For example, if you have 1 adapter and 10 I/O modules, then the chassis size is 11. Therefore, the thumbwheels must be set to 811.

for information on how to interpret its status indicators.

7. Remove power from the adapter and then address the error accordingly.

8. Once you have addressed the error, repeat Steps 1...5.

Adapters on page 24.

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

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.

– 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.

Rockwell Automation Publication 1734-UM018D-EN-E - September 2017 7

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

• 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

Use of the Common Industrial Protocol (CIP)

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.

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-optimization or enhanced rack-optimization connection) or specified for a particular module (using direct connection).

Support for Rackoptimization, Enhanced Rack-optimization, and Direct Connections

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.

The I/O adapters supports direct, rack-optimization, and enhanced rackoptimization 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-optimization 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-UM018D-EN-E - September 2017 9

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

IMPORTANT

Analog, safety, and specialty modules cannot participate in the rack-optimization connection; these modules require an enhanced rack-optimization or direct I/O connection.

Enhanced rack-optimization connections reduce the total number of connections needed to transfer data when using many digital and analog, or specialty modules in a system.

Rack-optimization 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-optimization 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-optimization connection to transfer the data, you only need a single connection – the connection to the I/O adapter.

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

• You can use only rack-optimization or enhanced rack-optimization connections to send data to and from digital I/O modules.

• Safety modules, IO link modules, and third-party I/O modules can not participate in enhanced rack-optimization connections.

• Enhanced rack-optimization does not support a listen only connection. Do not use enhanced rack-optimization if your application requires a connection for monitoring.

• 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-optimization or enhanced rack-optimization connection, a direct connection to that I/O module is required.

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

, for more information on connections.

Mixing Rack-optimization, Enhanced Rack-optimization, 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 or enhanced 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-optimization RPI.

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

Before You Begin

To effectively use your adapter, note the following considerations.

Determine Compatibility

If using the adapter with a 1756-ENBT module or 1768-ENBT module, use the following required firmware revisions for these bridge modules:

• 1756-ENBT firmware revision 4.006 or later

• 1768-ENBT firmware revision 2.003 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 does not reply to the request, the adapter responds with an error code indicating a timeout.

Configure Autobaud

Chapter Summary

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.

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.

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 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

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.

Rockwell Automation Publication 1734-UM018D-EN-E - September 2017 23

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

Set the Network Address

The adapters ship DHCP-enabled and with the pen-push Network address thumbwheels set to 999. You can set the network Internet Protocol (IP) address as follows.

Set the Network Address for POINT I/O Adapters

• Use the pen-push thumbwheels located on the adapter. Press either the + or - button with a pen tip to change the number and assign the IP address.

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

• Retrieve the IP address from non-volatile memory.

24 Rockwell Automation Publication 1734-UM018D-EN-E - September 2017

The adapter reads the thumbwheels first to determine if the thumbwheels are set to a valid number. You set the node address by using the 3-position pen-push thumbwheel using a pen tip.

Note: Press a pen tip into the center and perpendicular to the + or the - button to change the number. You only need a small amount of force to press the button (approximately 2N).

Valid settings range from 001…254. When you use the thumbwheel 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 set to 255.255.255.0. When you use the thumbwheel to assign an IP address between 002...254, the adapter gateway address is set to 192.168.1.1.

The adapter does not have a host name assigned, or use any Domain Name System when using the thumbwheel settings.

If the thumbwheels 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.

Configure the Adapter with RSLogix 5000 or Logix Designer Software Chapter 3

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 thumbwheels 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.

Use the Rockwell BootP/ DHCP Utility

The 1734-AENT/B adapter should be configured using only DHCP. 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 Util s 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.

Use DHCP Software to Configure Your Adapter

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 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.

See Configure the Adapter with Fixed IP Address adapter with a fixed IP address.

ATTENTION: To avoid unintended control or loss of control, the I/O adapter must be assigned a fixed IP address. A dynamically provided IP address should be used only at initial configuration. If a DHCP server is used, it must be configured to assign the same IP address to your adapter.

Failure to observe this precaution may result in unintended machine motion or loss of process control.

Series B Connection None Chassis Size 5 Electronic Keying Compatible Module Revision 4.3

The chassis size value equals 1 for the adapter plus the number of I/O modules installed (physically present on the I/O backplane).

Connection choices are the following:

• None – the adapter only makes a direct connection to each of the

modules referenced by the data. RPI is disabled in this case.

• Rack optimization – digital I/O data is collected into a rack image. This

rack image does not include analog or specialty I/O modules.

• Enhanced rack optimization – digital, analog, and specialty I/O data is

collected into a rack image.

• Listen only - rack optimization – read or verify input data only, but does

not control the modules. When you have multiple controllers, one controller is used to control and the other controllers are used to monitor. When the owning controller of rack-optimization connection closes the connection, the Listen-Only data will also stop.

Recover From an Overloaded Adapter

Each I/O connection established with the I/O adapter consumes a portion of microprocessor bandwidth. The amount of bandwidth used by a connection depends on several variables, such as the requested packet interval (RPI), number of I/O modules involved in the connection, and rate of change of the I/O.

The AENT adapter continuously monitors this bandwidth and rejects requests for new I/O connections when there is insufficient bandwidth available to support the new connection.

The condition where the I/O adapters cannot support the connection due to a limit of the bandwidth of the microprocessor is shown on the Connection tab of the Module Properties dialog.

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 include the following:

• Increase the RPI.

• Decrease the number of connections.

• Remove modules from the rack-optimization I/O connection.

• Remove the rack-optimization connection if there are no modules

participating in it.

This chapter guides you through the steps required to configure your AENT adapter with direct, rack-optimization, and enhanced rack-optimization I/O

(1)

connections using RSLogix 5000 or Logix Designer

You can mix I/O connection formats for different I/O modules communicating through the same adapter. I/O modules set up to use rack optimization or enhanced rack optimization communicate at the rate of the RPI configured for the adapter.

I/O modules controlled by a direct I/O connection communicate at their own set RPI. The RPI of the rack-optimization or enhanced rack-optimization I/O connection has no bearing on the direct I/O connections.

Access Module Data

Use the following information to use the I/O adapter data in the ladder logic program:

• POINT_IO_Adapter — the name you gave to your EtherNet adapter

• # — slot number of POINT I/O module

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

Use the controller tags in your ladder program to read input data or write output data.

• 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-optimization connection.

– Bit 0 is reserved for the adapter and always reports a value of 1. – 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-

optimization 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)
