1-6About the Logix5000 Communication Modules for EtherNet/IP NetworksBridge Across NetworksSome EtherNet/IP modules support the ability to bridge or routecommunication through devices, depending on the capabilities of theplatform and communication devices.The update time of local I/O modules may increase when bridgingmessages.IMPORTANTYou have a bridge when you have a connection betweencommunication devices on two separate networks. For example, thebridge device shown below has both EtherNet/IP and DeviceNetconnections so that Device 1 on the EtherNet/IP network cancommunicate with Device 2 on DeviceNet through the bridge.Device 1EtherNet/IP networkSwitchBridgeDeviceNet NetworkDevice 2CIP messages can bridge these networks:.CIP Messages That Originateon This NetworkCan Bridge to This NetworkEtherNet/IPControlNetDeviceNetRS-232 sRS-232yesyesyesyesPublication ENET-UM001E-EN-P - January 2006

For a CompactLogix or FlexLogix controller, map the datainto the DeviceNet I/O image and then use RSLinx OPC from the PCto the Logix5000 controller over the EtherNet/IP network. This avoidsusing the limited bridging resources of the CompactLogix or FlexLogixcontroller.You cannot bridge EtherNet/IP I/O across networks. I/O modulesmust be configured in either a local chassis or a remote chassis. Youcannot go through a gateway chassis to control I/O, even though insome circumstances, RSLogix 5000 software accepts such aconfiguration in the I/O Configuration folder.Publication ENET-UM001E-EN-P - January 2006

The IP address is in the formxxx.xxx.xxx.xxx where each xxx is a number between 0-255. These are reserved valuesyou cannot use: 127.0.0.1 0.0.0.0 255.255.255.255Subnet maskSubnet addressing is an extension of the IP address scheme that allows a site to use asingle network ID for multiple physical networks. Routing outside of the site continues bydividing the IP address into a net ID and a host ID via the class. Inside a site, the subnetmask is used to redivide the IP address into a custom network ID portion and host IDportion. This field is set to 0.0.0.0 by default.If you change the subnet mask of an already-configured module, you must cycle power tothe module for the change to take effect.Gateway1A gateway connects individual physical networks into a system of networks. When a nodeneeds to communicate with a node on another network, a gateway transfers the databetween the two networks. This field is set to 0.0.0.0 by default.Publication ENET-UM001E-EN-P - January 2006

3-2Configure an EtherNet/IP Module to Operate on the NetworkIf you use DNS addressing, or reference the module via host name inMSG instructions, define these parameters:EtherNet/IP Network ParameterDescriptionHost nameA host name is part of a text address that identifies the host for a module. The full textaddress of a module is host name.domain name.Domain nameA domain name is part of a text address that identifies the domain in which the moduleresides. The full text address of a module is host name.domain name. The domain namehas a 48-character limit.If you specify a DNS server, you must enter a domain name. Also, if you send email fromthe module, some mail relay servers require a domain name be provided during the initialhandshake of the SMTP session.Primary DNS server addressSecondary DNS server addressThis identifies the DNS server(s), if used in the network. You must have a DNS serverconfigured if you specified a domain name or a host name in the module’s configuration.The DNS server converts the domain name or host name to an IP address that can be usedby the network.The 1756-ENBT requires a DNS server address.For more information on DNS addressing, see page 3-10.Check with your Ethernet network administrator to determine if youneed to specify all of the above parameters.To configure these network parameters, the recommended method isto use the Rockwell Automation BOOTP/DHCP utility (see page 3-3).If this utility is not available, there are other methods you can use (seepage 3-5).Publication ENET-UM001E-EN-P - January 2006

Configure an EtherNet/IP Module to Operate on the NetworkAssign NetworkParameters via theBOOTP/DHCP UtilityIMPORTANT3-3By default, the EtherNet/IP module is BOOTP enabled. TheBOOTP/DHCP utility is a standalone program that is located in the: BOOTP-DHCP Server folder in the Rockwell Software programfolder on the Start menu (the utility is automatically installedwhen you install RSLinx software). Tools directory on the RSLogix 5000 installation CD.Before you start the BOOTP/DHCP utility, make sure you have thehardware (MAC) address of the module. The hardware address ison a sticker located on the side of the EtherNet/IP module. Thehardware address in a format similar to: 00-0b-db-14-55-35.This utility recognizes BOOTP-enabled devices and provides aninterface to configure a static IP address for each device.To use the BOOTP/DHCP utility:1. Start the BOOTP/DHCP software.2. Select Tool Network Settings.If appropriate for your network, enter the subnet mask, gatewayaddress, primary/secondary server addresses, and domain name.Click OK.Publication ENET-UM001E-EN-P - January 2006

3-4Configure an EtherNet/IP Module to Operate on the Network3. In the Request History panel you see the hardware addresses ofmodules issuing BOOTP requests. Double-click on the hardware(MAC) address of the module you want to configure.The hardware address is on a sticker located on the side of theEtherNet/IP module. The hardware address will be in a formatsimilar to 00-0b-db-14-55-35.4. The New Entry window appears with the module’s EthernetAddress (MAC).Enter the IP address or the host name. You can also enter adescription of the module. Click OK5. To permanently assign this configuration to the module,highlight the module and click on the Disable BOOTP/DHCPbutton. When power is recycled, the module uses theconfiguration you assigned and not issue a BOOTP request.If you do not select the Disable BOOTP/DHCP button, on apower cycle, the host controller clears the current IPconfiguration and will again begin sending BOOTP requests.Publication ENET-UM001E-EN-P - January 2006

It might also offer feweropportunities for assigning duplicate IP addresses.

You might have todisconnect from the uplink to set the address and have the moduleremember its static address before reconnecting to the uplink. This isnot a problem if you have node names configured in the module andleave DHCP enabled.Using RSLinx software to set the IP addressTo use RSLinx to configure the EtherNet/IP module:1. Make sure the module is installed and powered up.Publication ENET-UM001E-EN-P - January 2006

Configure an EtherNet/IP Module to Operate on the Network3-7Use RSLogix 5000 software to set the IP addressTo use RSLogix 5000 software to configure the EtherNet/IP module:1. Make sure the module is installed and has power.2. Connect to the controller via a serial, or other network,connection.3. Start RSLogix 5000 software. In the Controller Organizer, selectproperties for the EtherNet/IP module.4. Select the Port Configuration tab and specify the IP address andthe other network parameters, if needed. Click Apply and thenclick OK.This sets the IP address in the hardware. This IP address shouldbe the same IP address you assigned under the General tab.On this screen, you can also specify port speed (10 Mbps or100 Mbps) and duplex mode (autonegotiate, half duplex, or fullduplex). All modules on the same subnet must be configured forthe same port speed and duplex mode.Use DHCP software to set the IP addressDynamic Host Configuration Protocol (DHCP) software automaticallyassigns IP addresses to client stations logging onto a TCP/IP network.DHCP is based on BOOTP and maintains some backwardcompatibility. The main difference is that BOOTP allows for manualconfiguration (static), while DHCP allows for both static and dynamicPublication ENET-UM001E-EN-P - January 2006

3-8Configure an EtherNet/IP Module to Operate on the Networkallocation of network addresses and configurations to newly attachedmodules.Be cautious when using DHCP software to configure your module. ABOOTP client, such as the EtherNet/IP modules, can boot from aDHCP server only if the DHCP server is specifically written to alsohandle BOOTP queries. This is specific to the DHCP software packageyou use. Check with your system administrator to see if your DHCPpackage supports BOOTP commands and manual IP allocation.ATTENTION!Duplicate IP AddressDetectionThe EtherNet/IP module must be assigned a fixednetwork address. The IP address of this module mustnot be dynamically provided.Failure to observe this precaution may result inunintended machine motion or loss of processcontrol.These EtherNet/IP modules (and their future revis
