Device-Level Ring (DLR) Basics

Introduction Prior to the introduction of products with embedded switch technology the traditional EtherNetIP network topology has been a star type End devices are connected and communicate with each other via a switch

The EtherNetIP embedded switch technology offers alternative network topologies for interconnecting EtherNetIP devices It embeds switches into the end devices themselves

ArmorStart with EtherNetIP Overview

The ArmorStart with EtherNetIP incorporates the advantages of distributed motor control EtherNetIP communication and Embedded Switch Technology The ArmorStart EtherNetIP family includes full voltage or Sensorless Vector Control AC drive motor starters designed for most of your critical applications ArmorStart with EtherNetIP is a simple seamless and cost-effective method of integrating pre-engineered starters IO and network capabilities in your On-Machine architecture The dual port 10100 Mbps embedded Ethernet switch supports Linear and Device Level Ring Topologies in addition to the traditional star topology

IMPORTANT Products with EtherNetIP embedded switch technology have two ports to connect to a linear or DLR network in a single subnetThese ports cannot be used as two Network Interface Cards (NICs) connected to two different subnets The two ports share one IP Address and MAC Address


Chapter 1 Device-Level Ring (DLR) Basics

What is a Device-level Ring (DLR) Network

A DLR network is a single-fault tolerant ring network intended for the interconnection of automation devices This topology is also implemented at the device level No additional switches are required

The graphic below shows an example of an ArmorStart LT Bulletins 291 and 291E and an ArmorStart Distributed Motor Controller Bulletin 280E in a DLR network

Figure 1 - Example DLR Network

The advantages of the DLR network include

bull Simple installation

bull Media resiliency to a single point of failure on the network

bull Fast recovery time when a single fault occurs on the network (lt3 ms convergence for up to 50 nodes on ring)

The primary disadvantage of the DLR topology is the additional effort required to set up and use the network when compared to a linear or star network However use of this Application Guide should minimize the amount of additional effort that is required

DLR Network Elements A DLR network is made up of the following devicesbull Supervisor Node

ndash Active Supervisor Nodendash Back-up Supervisor Node (optional)

bull Ring Node

Each of these device types and how they work in a DLR network are described in the following sections


Device-Level Ring (DLR) Basics Chapter 1

Supervisor Node

A DLR network requires at least one node to be configured as a ring supervisor Currently several Rockwell Automation products support the ring supervisor functionality

Active Ring Supervisor

When multiple nodes are enabled as supervisor the node with the numerically highest precedence value becomes the active ring supervisor the other nodes automatically become back-up supervisors

The ring supervisor provides the following primary functionsbull Verifies the integrity of the ringbull Reconfigures the ring to recover from a single fault bull Collects diagnostic information for the ring

Back-up Supervisor Node

At any point in time there will be only one active supervisor on a DLR network However we recommend that at least one other supervisor-capable node be configured to act as a back-up supervisor During normal operation a back-up supervisor behaves like a ring node If the active supervisor node operation is interrupted for example it experiences a power-cycle the back-up supervisor with the next numerically highest precedence value becomes the active supervisor

If multiple supervisors are configured with the same precedence value (the factory default value for all supervisor-capable devices is 0) the node with the numerically highest MAC address becomes the active supervisor

We recommend that youbull Configure at least one back-up supervisorbull Configure your desired active ring supervisor with a numerically higher

precedence value as compared to the back-up supervisors

IMPORTANT Out of the box the supervisor-capable devices have their supervisor function disabled so they are ready to participate in either a linearstar network topology or as a ring node on an existing DLR networkIn a DLR network at least one of the supervisor-capable devices must be configured as the ring supervisor before physically closing the ring If not the DLR network will cause significant network issues that can only be resolved by disconnecting the final connection

IMPORTANT While a back-up supervisor is not required on a DLR network it is recommended that at least one back up ring supervisor be configured for the ring network



bull Keep track of your networkrsquos supervisor-precedence values for all supervisor-enabled nodes

For more information about how to configure a supervisor see Construct and Configure a Device-level Ring Network on page 15

Ring Node

A ring node is any node that operates on the network to process data that is transmitted over the network or to pass on the data to the next node on the network When a fault occurs on the DLR network these reconfigure themselves and relearn the network topology Additionally ring nodes can report fault locations to the active ring supervisor

DLR Network Operation During normal network operation an active ring supervisor uses beacon and other DLR protocol frames to monitor the health of the network Back-up supervisor nodes and ring nodes monitor the beacon frames to track ring transitions between Normal (all links working) and Faulted (the ring is broken in at least one place)

Two beacon-related parameters can be configured

bull Beacon interval - Frequency at which the active ring supervisor transmits a beacon frame through both of its ring ports

bull Beacon timeout - Amount of time that supervisor or ring nodes wait before timing out the reception of beacon frames and taking appropriate action

These parameters impact Network Recovery Performance For information on these performance times see page 58 For information on how to set these parameters see Construct and Configure a Device-level Ring Network on page 15

IMPORTANT Do not connect non-DLR (single port) devices directly to the DLR network Non-DLR devices should be connected to the network through 1783-ETAP 1783-ETAP1F or 1783-ETAP2F EtherNetIP taps like the examples shown below



During normal operation one of the active supervisor nodersquos network ports is blocked for DLR protocol frames However the active supervisor node continues to send beacon frames out of both network ports to monitor network health The following graphic shows the use of beacon frames sent from the active ring supervisor

Figure 2 - Normal DLR Network Operation

A second category of ring nodes known as announce frame ring nodes can be designed to participate in a DLR network The active supervisor sends announce frames out one of its ports once per second or on detection of a ring fault DLR networks with announce frame ring nodes have slightly longer recovery times than beacon frame nodes

Number of Nodes on a DLR Network

Rockwell Automation recommends that you use no more than 50 nodes on a single DLR or linear network If your application requires more than 50 nodes we recommend that the nodes are segmented into separate but linked DLR networks

With smaller networksbull There is better management of traffic on the networkbull The networks are easier to maintainbull There is a lower likelihood of multiple faultsbull Recovery time is shorter

Additionally on a DLR network with more than 50 nodes network recovery times from faults are higher than those listed in Network Recovery Performance on page 58



DLR Network Fault Management

The network may occasionally experience faults that prevent the normal transmission of data between nodes The DLR network can protect your application from interruptions resulting from a single fault To maintain the resiliency of your ring your application should monitor the health of the ring The ring may be faulted while all higher-level network functions such as IO connections are operating normally

Fault location information is available from the active supervisor For more information on how to obtain fault location information see Monitor a DLR Network on page 37

After a fault occurs the active supervisor reconfigures the network to continue sending data on the network

Network Reconfiguration after a Fault

The following graphic shows the network configuration after a failure occurs with the active ring supervisor passing traffic through both of its ports thus maintaining communication on the network

Install Devices on a DLR Network

The next step to configure a DLR network is to connect all devices to the network One connection should be left unmade That is temporarily omit the physical connection between two nodes on the ring network because the factory default settings of DLR devices are set to operate in linearstar mode or as ring nodes on existing DLR networks

For more information on installing the EtherNetIP network (cable requirements maximum distance etchellip) refer to the EtherNetIP Media Planning and Installation Manual which can be downloaded here

Construct and Configure a Device-level Ring Network with ArmorStarts Chapter 2

ArmorStart Addressing Configuration

Before using the ArmorStart in an EtherNetIP network an IP address subnet mask and optional Gateway address must be configured This section describes how to set up the IP Address of an ArmorStart in three different ways using the BootPDHCP Server the Rotary Network Address Switches and the internal web server

Note When using the AOP it is not configuring the IP Address of the ArmorStart it is just assigning the same IP address that was set-up using the Rotary Network Address Switches or the web page so that communication is established

Using the BootPDHCP Server

The Rockwell Automation BootPDHCP utility is a standalone program that incorporates the functionality of standard BootP software with a user-friendly graphical interface It is located in the Utils directory on the RSLogix 5000 installation CD The ArmorStart EtherNetIP adapter must have DHCP enabled (factory default) to use the utility

DHCP (Dynamic Host Configuration Protocol) software automatically assigns IP addresses to client stations logging onto a TCPIP network When DHCP is enabled (factory default enabled) the unit will request its network configuration from a BootPDHCP server Any configuration received from a DHCP server will be stored in non-volatile memory The ArmorStart EtherNetIP will remember the last successful address if the DHCP is enabled The possibility exists that the adapter will be assigned a different IP address which would cause the adapter to stop communicating with the ControlLogix controller

Using the Rotary Network Address Switches

The three rotary network address switches can be found on the IO section of the ArmorStart The rotary network address switches are set to 999 and the DHCP is enabled as the factory default The ArmorStart reads these switches first to determine if the switches are set to a valid IP address between 1hellip254 When switches are set to a valid number the IP address will be 1921681_ _ _ [switch setting]

RJ45 ndash RJ45 Ethernet cable ENET-IN001A 1585J-M8PBJM-2

RJ45 ndash M12 Ethernet cable ENET-IN001A 1585D-M4TBJM-1

M12 ndash M12 Ethernet cable ENET-IN001A 1585D-M4TBDE-2




To set up the IP Address using the rotary network address switches

1 Remove the protective caps from the rotary switches

2 Set the Network IP address by adjusting the three switches on the front of the IO module using a flat head screwdriver

3 Set up the switches in a range from 001 to 254 In this example they are set to a1 When the switches are set to a valid number the adapterrsquos IP address will be 1921681xxx (where xxx represents the number set on the switches) In this example the IP address is 1921681163 The adapterrsquos subnet mask will be 2552552550 and the gateway address is set to 0000 A power cycle or a type 1 network reset is required for any new IP address switch setting to take effect

Note The user cannot change the IP address from 1921681xxx when using the IP address switches The top three octets are fixed DHCP or the embedded web server must be used to configure the address to a value different than 1921681xxx Also the adapter will not have a host name assigned or use any Domain name System when using the rotary switch settings

4 If the switches are set to an invalid value (such as 000 or value greater than 254) the adapter will check to see if the DHCP is enabled If so the adapter requests an address from a DHCP server The DHCP server will also assign other Transport Control Protocol (TCP) parameters If DHCP is not enabled the adapter will use the IP address (along with other TCP configurable parameters) stored in nonvolatile memory



Using the ArmorStart Internal Web Server

Rockwell Automation provides an internal embedded web server with each EtherNetIP version of ArmorStart The internal web server allows you to view information and configure the ArmorStart via a web browser The internal web server can be used to set up the ArmorStart IP address by performing the following this steps

1 Open your preferred internet web browser

2 Enter the IP address of the desired ArmorStart For this example use 1921681163

Note 1921681163 is not the factory default IP address

3 The web server shown below should appear in your web browser



4 Click in the administrative settings folder to expand it and the following is displayed

5 Click in the Network Configuration tab and a prompt to enter a User Name and a Password is displayed Enter the pre-set User Name and Password or if they have not been set up previously use the default User Name The default User Name is Administrator and there is no password set by default

6 After the appropriate User Name and Password is entered the screen below is displayed From this screen the Ethernet Configuration can be changed For example the default IP address shown is changed from 1921681163 to 101010101 After a power cycle the new address must be used to access the web page and the other devices on the network would also require their IP addresses to be reconfigured



Configure Supervisor Nodes on a DLR Network

After the devices are installed on the DLR network at least one supervisor node must be configured Ring nodes do not require any DLR network configuration

Before a DLR network can be completed (install your devices on the network and make all physical connections) a ring supervisor must be configured and enabled in

bull RSLogix 5000 programming software orbull RSLinx Classic communication software

This section shows how to use RSLogix 5000 programming software beginning on page 22 and RSLinx Classic communication software beginning on page 29 to configure and enable a ring supervisor

Configure a Ring Supervisor in RSLogix 5000 Programming Software

To configure the 1756-EN2TR module or the 1783-ETAP 1783-ETAP1F or 1783-ETAP2F taps as a ring supervisor use the devicersquos Add-on Profile (AOP) in RSLogix 5000 programming software version 1701 or later

For more information regarding the Required Add-On Profile Revision required go to Appendix B

To configure a ring supervisor in RSLogix 5000 programming software follow these steps

IMPORTANT The steps to configure a ring supervisor via software are basically the same for the 1756-EN2TR module and the 1783-ETAP 1783-ETAP1F and 1783-ETAP2F taps This example shows how to configure the 1756-EN2TR moduleOnly the 1783-ETAP 1783-ETAP1F and 1783-ETAP2F taps in the IO Configuration must be configured if you plan to enable the tap as a ring supervisor If the tap will not be used as a ring supervisor we recommend that it is not added to the IO ConfigurationAdditionally to configure a 1783-ETAP 1783-ETAP1F or 1783-ETAP2F tap as a supervisor via software or with its DIP switches an IP address must first be assigned The tap does not require an IP address if it is used as a ring node or has its supervisor function enabled by a DIP switchFor more information on how to use a tap switch to configure it as a ring supervisor see Chapter 5 in the EtherNetIP Embedded Switch Technology Manual To download the manual go to httpliteraturerockwellautomationcomidcgroupsliteraturedocumentsapenet-ap005_-en-ppdf

Complete the Physical Connections of the Network

After the ring supervisor nodes are configured and enabled the physical connection of the network must be completed to establish a complete DLR network

The figure below shows an example DLR network with all physical connections complete

Figure 4 - Example Device-level Ring Topology with All Connections Complete



Verify Supervisor Configuration

The configuration and overall DLR network status can be verified in either RSLogix 5000 programming software or RSLinx Classic communication software

1 Access the supervisor nodersquos properties as shown previously in this chapter

2 Click the Network tab

3 Check the Network Topology and Network Status Fields

For a 1756-EN2TR module or the 1783-ETAP 1783-ETAP1F and 1783-ETAP2F tap the supervisor configuration can also be verified through the modulersquos diagnostic web pages For more information on monitoring diagnostics via an EtherNetIP modulersquos web pages see Monitor a DLR Network starting on page 37



IGMP Snooping This functionality is enabled by default in the 1783-ETAP 1783-ETAP1F and 1783-ETAP2F taps and is commonly used to manage multicast traffic on the network When in use this functionality allows the tap to multicast data to only those devices that need the data rather than to all devices connected to the network

For snooping to work there must be a device present that is running a querier Typically the device is a router or a switch such as the Stratix 6000 Stratix 8000 or Stratix 8300 managed switch

Once DHCP is enabled the switch could change the IP addresses on the ArmorStarts depending on network demand which could cause RSlogix5000 to loose communication with the device as connectivity is established via the AOP in the initial configuration

IGMP Querier This functionality is disabled by default The IGMP Querier functionality enables a 1783-ETAP 1783-ETAP1F or 1783-ETAP2F tap or switch such as a Stratix managed switch to send out a query to all devices on the network It determines what multicast addresses are of interest to a specific node or a group of nodes

The IGMP Querier functionality should be enabled for at least one node on the network The 1783-ETAP 1783-ETAP1F or 1783-ETAP2F tap managed switches and routers are examples of devices that support IGMP Querier functionality

IMPORTANT If DHCP for the Armostart is still required the Internet Group Management Protocol (IGMP) snooping on the E-tap must be disabled via the AOP

IMPORTANT If the IGMP Querier functionality is not enabled for at least one node on the network multicast traffic on the network may eventually create network performance issues



However for all devices that are configured on the network with the IGMP Querier parameter enabled an IP address other than the factory default value must also be set for those devices If multiple devices on the network enable this functionality only the node with the lowest IP address becomes the active IGMP Querier node

IGMP Version

If the IGMP Querier is enabled a Querier Version must be selected The default version is Version 2

Troubleshoot a DLR Network

Introduction Use this chapter to learn how to troubleshoot the DLR network

General Solutions for Linear or DLR Networks

Before attempting to correct specific faults on the linear or DLR network we recommend that you first take the following actions when a fault appears

bull For a DLR networkndash Verify that at least one node has been configured as a supervisor

on the network and that Network Topology = Ringndash Verify that all cables on the network are securely connected

to each devicendash Verify that all devices that require an IP address have one assigned

correctlyndash Check the Network Status field on the active supervisor nodersquos status

page to determine the fault typebull For a linear network

ndash Verify that none of the nodes are configured as a supervisor on the network and that Network Topology = LinearIf any nodes on a linear network are configured as a supervisor it may impact communication to other devices connected to the network

ndash Verify that all cables on the network are securely connected to each device

ndash Verify that all devices that require an IP address have one assigned correctly

If the fault is not cleared after completing the actions listed above use the tables in the rest of this chapter to troubleshoot issues specific to a DLR network or a linear network

Chapter 4 Troubleshoot a DLR Network

Duplicate IP Address Detection

Some EtherNetIP communication modules support duplicate IP address detection The module verifies that its IP address does not match any other network devicersquos IP address when performing either of these tasks

bull Connect the module to an EtherNetIP network

bull Change the modulersquos IP address

If the modulersquos IP address matches that of another device on the network the modulersquos EtherNetIP port transitions to Conflict mode In Conflict mode these conditions exist

bull OK status indicator is blinking red

bull Network (NET) status indicator is solid red

bull On some EtherNetIP communication modules the module status display indicates the conflict

The display scrollsOK ltIP_address_of_this_modulegt Duplicate IP

ltMac_address_of_duplicate_node_detectedgt

For example OK 108860196 Duplicate IP - 0000BC0234B4

bull On some EtherNetIP communication modules the modulersquos diagnostic webpage displays information about duplicate IP address detection

For more information on which EtherNetIP communication modules support displaying duplicate IP address on their diagnostic webpage see the Technical Note titled Logix modules Duplicate IP address detection enhancement 118216 in the Technical Support Knowledgebase available at httpwwwrockwellautomationcomknowledgebase


Troubleshoot a DLR Network Chapter 4

Specific Issues on the DLR Network

Use the following table to troubleshoot possible specific issues on the DLR or linear network that are not solved by the actions described on the previous page

Issue Description Solution

Supervisor Reports a Ring Fault A link on the DLR network may be brokenbull intentionally for example because of adding or deleting nodes but not making all

physical connections to restore the setup of the network withwithout the nodebull unintentionally for example because a cable is broken or a device malfunctionsWhen this fault occurs the adjacent nodes to the faulted part of the network are displayed in the Ring Fault group and the Network Status field = Ring FaultThe screen shot below shows the Ring Fault section with IP addresses appearing for the last active nodes The faulted node is between nodes 108880115 and 108880208 If the IP address of either node is not available the software will display the nodersquos MAC ID

Once the fault is corrected the ring is automatically restored and the Network Status field returns to Normal

Determine where the fault condition exists and correct itClick the Refresh Communication link as needed to update the Ring Fault information to determine where the fault condition existsFinally DevicePort Debugging Mode functionality on the 1783-ETAP tap may be used to analyze a suspicious nodeFor more information refer to Device Port Debugging Mode on page 59




Rapid Ring Fault When a Rapid Ring Fault occurs the following events occurbull The active supervisor will block traffic on port 2 resulting in possible network

segmentation that is some nodes may become unreachablebull The Link 2 status indicator on the active supervisor is offbull As soon as the fault occurs for both RSLogix 5000 programming software and

RSLinx communication software the Status field = Rapid FaultRestore Cycles

Any of the following may cause a Rapid Ring Faultbull 5 intentional disconnectionsreconnections of a node from the network within 30

secondsbull A duplex mismatch between two connected devicesbull Electromagnetic noise on the networkbull Unstable physical connections such as intermittent connectorsGiven the nature of a Rapid Ring Fault the Last Active Node information may not be accurate when a Rapid Ring Fault condition is present

Multiple possible solutions existbull For the disconnections and reconnections issue no

solution is requiredClear the fault after reconnecting the device to the network permanentlybull For the duplex mismatch issue reconfigure the duplex

parameters to make sure they match between the devices

bull For the electromagnetic noise issue determine where the noise exists and eliminate it or use a protective shield in that location

bull For the unstable connections issue determine where they exist on the network and correct them

bull Check the media counters for all devices on the network The device with the highest media counter count is most likely causing the Rapid Ring Fault

bull Remove devices from the network one by one If the Rapid Ring Fault disappears after a device is removed that device is causing the fault

bull DevicePort Debugging Mode functionality on the 1783-ETAP tap may be used to analyze a suspicious node

For more information refer to Device Port Debugging Mode on page 59bull Finally the Beacon Interval or Timeout configuration

may not be appropriate for the networkHowever if these values need to be changed we recommend that you contact Rockwell Automation technical supportOnce the fault is fixed click Clear Fault




Partial Fault Condition A partial network fault occurs when traffic is lost in only one direction on the network because a ring member is not forwarding beacons in both directions for example a component failureThe active ring supervisor detects a partial fault by monitoring the loss of Beacon frames on one port and the fault location appears in the Ring Fault section of the Network tab When a partial fault is detected the active ring supervisor blocks traffic on one port At this point the ring is segmented due to the partial fault condition The nodes adjacent to the faulted part of the network are displayed in the Ring Fault group with either IP addresses or MAC IDs for each node displayedWhen this fault occurs the Network Status field = Partial Fault ConditionOnce the fault is corrected it automatically clears and the Network Status field returns to Normal

Determine where the fault condition exists and correct itAdditionally the DevicePort Debugging Mode functionality also known as Port Mirroring on a 1783-ETAP 1783-ETAP1F or 1783-ETAP2F tap may be used to analyze a suspicious nodeFor more information refer to Device Port Debugging Mode on page 59

Media Counter Errors or Collisions

The media counters screen displays the number of physical layer errors or collisions The screen below indicates where to check for errors encountered Error levels are displayed depending on what caused the error For example an Alignment Error is displayed in the Alignment Error field

On a DLR network it is not uncommon to see low levels of media counter errors For example if the network breaks a low level of media counter errors appears With a low level of media counter errors the value typically does not continuously increase and often clearsA high level of media counter errors typically continues to increase and does not clear For example there is a mismatch of speed between two linked nodes a high level of media counter errors appears steadily increasing and not clearingTo access the RSLinx screen above browse the network right-click on the device select Module Properties and click the Port Diagnostics tab

Some example solutions includebull Check for a mismatch of speed andor duplex between

two linked nodesbull Verify that all cables on the network are securely

connected to each devicebull Check for electromagnetic noise on the network If you

find it eliminate it or use a protective shield in that location



Network Recovery Performance

When measuring the networkrsquos performance with regard to dealing with fault conditions consider the network recovery time Network recovery is the time for all of the following to take place

1 The supervisor node recognizes that a fault exists on the network

2 The supervisor node reconfigures the network because of the fault

3 The supervisor node communicates to the network nodes that a fault condition exists

4 The network nodes reconfigure themselves because of the fault

With the default beacon interval value of 400 mS and beacon timeout value of 1960 mS the worst-case time for network recovery times are

bull 2890 mS for a copper DLR network This recovery time is based on 100 m copper segments between nodes on the network

bull 3140 mS for a fiber-optic DLR network This recovery time is based on 2 kM fiber-optic cable segments between nodes on the network

When considering the values listed above keep in mind

bull Recovery time may actually occur faster than the times listed

bull The recovery times listed above assume that your networkrsquos nodes are operating at 100 Mbps speed and full-duplex mode We recommend that your nodes generally operate in this mode for DLR networks

bull If other node conditions exist such as a node operating at 10 Mbps full-duplex or 10100 Mbps half-duplex the recovery times will vary from the times listed above

If this is the case for your application the beacon interval and beacon timeout will need to be changed We recommend that you first contact Rockwell Automation technical support if these parameters need to be changed

bull The value assumes that the majority of the traffic on your network is EtherNetIP traffic



Device Port Debugging Mode

This functionality is disabled by default Device Port Debugging mode which is similar to port mirroring can be used to monitor data received on the 1783-ETAP 1783-ETAP1F or 1783-ETAP2F taprsquos two network ports Monitor the data over the device port to a device such as a personal computer running a protocol analyzer application for advanced network debugging or analysis

When device port debugging is used on a 1783-ETAP the device connected to the 1783-ETAP taprsquos front port receives all of the data traversing the ring (both directions)

Device Port Debugging Example Network

When using the Device Port Debugging mode functionality insert the 1783-ETAP with the network analyzer connected to the device port It is inserted at the spot on the ring network where the node in question is located The graphic below shows a 1783-ETAP tap inserted in the network

IMPORTANT This functionality should be used only when troubleshooting the network and not in normal network operation



Combined total network bandwidth of the traffic received on the two 1783-ETAP 1783-ETAP1F or 1783-ETAP2F taprsquos ports connected to the network should not exceed the taprsquos device port capacity The speed setting determines the device portrsquos capacity

Configure the device port on a 1783-ETAP 1783-ETAP1F or 1783-ETAP2F tap to either of two speed settings

bull 100 Mbps - default settingbull 10 Mbps

If the bandwidth exceeds the capacity of the taprsquos device port some frames from the ring will be dropped before reaching the device port These dropped frames do not impact the traffic on the rest of the DLR network

The device port setting determines how much network traffic the 1783-ETAP 1783-ETAP1F or 1783-ETAP2F tap can handle before dropping frames The circled section in the graphic below shows the Port Buffer Utilization of the Device Port In this example the value is zero because a ring fault exists on the network


Appendix A

Network Usage Guidelines and Recommendations

Consider the following guidelines and recommendations when using a DLR or linear network

GuidelineRecommendation Explanation

Use fewer than 50 nodes on a single DLR networkIf your application requires more than 50 nodes we recommend that the nodes are broken into separate but linked DLR networks

If you use more than 50 nodes on a single DLR networkbull Your network has a greater chance of multiple faults

occurring on the networkbull Network recovery times from faulted DLR network

are higher

Do not configure a supervisor on a linear network If your linear network includes non-DLR nodes and has a supervisor-enabled node on the network it may impact communication to non-DLR devices connected to the linear network

If you must connect a device that is running at 10 Mbps to a DLR or linear network do so through a 1783-ETAP 1783-ETAP1F or 1783-ETAP2F tap device port

The 1783-ETAP 1783-ETAP1F and 1783-ETAP2F taps can operate at 100 Mbps on the DLR network this is the optimal speed for a network If you connect a 10 Mbps device directly to the network instead of through a tap the linear or DLR network traffic slows to 10 MbpsAdditionally if the 10 Mbps device is connected to the network without a 1783-ETAP tap network recovery times are significantly impacted

Configure multiple supervisor nodes per ring If your DLR network only has one supervisor and the supervisor experiences a fault none of the other nodes become the active supervisor In this case the network becomes a linear network until the fault is corrected and the DLR network restoredAnother reason to configure multiple supervisor nodes is for replacing an active supervisor node with an out-of-box replacement the new device will not be enabled as a supervisor (by default) and there would still be no supervisor on the network


Appendix A Network Usage Guidelines and Recommendations


Connect switches to a DLR network via 1783-ETAP 1783-ETAP1F or 1783-ETAP2F taps

If switches are connected to the DLR network without the use of a 1783-ETAP 1783-ETAP1F or 1783-ETAP2F tap the network may experience unpredictable behavior and network performance is unknown

Run all nodes on the DLR network at 100 Mbps and in Full-Duplex mode

These configuration values provide the best performance for your networkAdditionally we recommend that youbull Use auto-negotiate for all nodes on the DLR networkbull Do not use auto-negotiate on one node and then force

speed on the next node linked to it

In a linear network the number of nodes to use is application specific based on the considerations described in the next box

When determining the number of nodes to use on a linear network consider the followingbull There is a delay per node as information is transmitted

to each successive node used on the networkndash The typical delay on a linear network with 100 m

copper segments between nodes is 30 mSndash The typical delay on a linear network with 2 kM

fiber-optic segments between nodes is 40 mS

The greater the number of nodes on the network the longer the total time for information to be transmitted across the entire networkbull The single point of failure possibility is greater with

each additional connectionbull Troubleshooting the network may be more difficult

with a higher number of nodes

The total time for information to be transmitted across the entire network and its effect on how many nodes to use on a linear network is related to the Requested Packet Interval (RPI)Verify that the total time to transmit information from the first node to the last node on the network is less than the RPI Make sure the network is not loaded beyond 90 of capacity


Network Usage Guidelines and Recommendations Appendix A


Do not physically close a DLR network without a supervisor configured on the network

A DLR network without a supervisor node results in a network stormIf you do close the DLR network without a supervisor configured break the ring and configure at least one supervisor before physically reconnecting the network

Use the default values for the followingbull Beacon Intervalbull Beacon Timeoutbull Ring Protocol VLAN ID

Changing the default values for the parameters Beacon Interval Beacon Timeout and Ring Protocol VLAN ID can result in unpredictable network behavior and negatively impacted network performanceThe default values are optimized for a network withbull 50 or fewer nodes are on the networkbull All nodes are operating at 100 Mbps and full-duplex

modebull At least 50 of the network traffic bandwidth being

EtherNetIP trafficIf you think the values of the Beacon Interval Beacon Timeout or Ring Protocol VLAN ID need to be changed for example if any node on ring is not operating at 100 Mbps and full-duplex mode we recommend that you first contact Rockwell Automation technical support

If DHCP for the ArmorStarts is still required you will need to disable Internet Group Management Protocol (IGMP) snooping on the E-tap via the AOP

IGMP Snooping is enabled by default in the 1783-ETAP 1783-ETAP1F and 1783-ETAP2F taps and is commonly used to manage multicast traffic on the network When in use this functionality allows the tap to multicast data to only those devices that need the data rather than to all devices connected to the networkOnce DHCP is enabled the switch could change the IP addresses on the ArmorStarts depending on network demand which could cause RSlogix5000 to loose communication with the device as connectivity is established via the AOP in the initial configuration

The IGMP Querier functionality should be enabled for at least one node on the network

This functionality is disabled by default The IGMP Querier functionality enables a 1783-ETAP 1783-ETAP1F or 1783-ETAP2F tap or switch such as a Stratix managed switch to send out a query to all devices on the network to determine what multicast addresses are of interest to a specific node or a group of nodesIf the IGMP Querier functionality is not enabled for at least one node on the network multicast traffic on the network may eventually create network performance issuesThe 1783-ETAP 1783-ETAP1F or 1783-ETAP2F taps managed switches and routers are examples of devices that support IGMP Querier functionality

Required Firmware Revisions

Required Firmware Revision for an Add-On Profile

➊ The ControlFLASH Firmware Upgrade software tcan be used o upgrade a 1756-EN2TR module from firmware revision 21 to 3x or later1x or later3x or later2x or later

➋ The ControlFLASH Firmware Upgrade software can be used to upgrade a 1783-ETAP tap from firmware revision 11 to 2x or later

To download new firmware go to httpwwwrockwellautomationcomsupportamericasindex_enhtml

If the firmware revision is upgraded on the module or tap the required AOP revision listed above must be used for that revision For example if the 1756-EN2TR module is upgraded to firmware revision 3x or later AOP revision 2x or later must be used in the RSLogix 5000 programming software

Additionally if the firmware revision is upgraded on the module or tap the required RSLinx communication software must also be used for that firmware revision For more information on which RSLinx software version is required for each firmware revision see page 66

For both the 1756-EN2TR module and 1783-ETAP tap make sure that the Major Revision configured on the General tab of the devicersquos RSLogix 5000 programming software configuration matches the major revision of the physical module

IMPORTANT To download an AOP go to httpsupportrockwellautomationcomcontrolflashLogixProfileraspDepending on the firmware revision of your product a specific AOP version must be used
