Configure the EtherNet/IP Communications Auxiliary

Introduction

Determining Network Parameters

This chapter describes how to configure an EtherNet/IP Communications Auxiliary to operate on an EtherNet/IP network.

When you first install an EtherNet/IP Communications Auxiliary, the module is Dynamic Host Configuration Protocol (DHCP) enabled.

To operate an EtherNet/IP network, you must define these parameters.

Table 2 - EtherNet/IP Network Parameters

Network Parameter Description

IP Address The IP address uniquely identifies the module. The IP address

is in the form xxx.xxx.xxx.xxx where each xxx is a number from

0...255. Do not use the following IP addresses, as these are reserved values:

• 0.0.0.1...0.255.255.255

• 127.0.0.0...127.255.255.255

• 224.255.255.255...255.255.255.255

Subnet Mask Subnet addressing is an extension of the IP address scheme

that allows a site to use a single network ID for multiple physical networks. Routing outside of the site continues by dividing the IP address into a net ID and a host ID via the class. Inside a site, the subnet mask is used to redivide the IP address into a custom network ID portion and host ID portion. NOTE: If you change the subnet mask of an alreadyconfigured module, you must cycle power to the module for the change to take effect.

Gateway A gateway connects 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.

If DNS addressing is used or if the module is referenced via a host name in an MSG instruction, the following parameters must be defined.

NOTE: Consult with your Ethernet network administrator to determine if these

parameters need to be specified.

have a DNS server configured if you specify an SMTP server with a name. The DNS server converts the domain name or host name to an IP address that can be used by the network.

For more information on DNS addressing, refer to page 23.

Setting the IP Network Address

An EtherNet/IP Communications Auxiliary ships with DHCP enabled. You can set the network Internet Protocol (IP) address by using:

• the EtherNet/IP node address selection switches,

• a Bootstrap Protocol (BOOTP)/Dynamic Host Configuration Protocol

(DHCP) server (e.g., the Rockwell Automation BOOTP-DHCP Server Utility, which is included with Rockwell Software’s RSLinx™ Classic software), OR

• a web browser and MAC scanner software.

EtherNet/IP Node Address Selection Switches

The EtherNet/IP Communications Auxiliary comes with three node address selection switches that allow the user to select the last octet for the IP address

192.168.1.xxx.

EXAMPLE

IMPORTANT

When the top dial is set to 1, the middle dial is set to 2, and the bottom dial is set to 3, the resulting IP address is: 192.168.1.123.

Assign Network Parameters via the BOOTP/ DHCP Utility

When the node address selection switches are set to a value greater than 255, the IP address is set to DHCP Enabled or programmed for a static IP address.

By default, the EtherNet/IP Communications Auxiliary is DHCP Enabled. The BOOTP/DHCP utility is a standalone program that is located in the BOOTPDHCP Server folder accessed from the Start menu.

Before starting the BOOTP/DHCP utility: Make sure you have the hardware MAC ID of the module, which is printed on the front of the EtherNet/IP Communications Auxiliary. The MAC ID has a format similar to: 00-0b-db-14-55-35.

This utility recognizes DHCP-enabled devices and provides an interface to configure a static IP address for each device.

To assign network parameters via the BOOTP/DHCP utility, perform this procedure:

1. Execute the BOOTP/DHCP software.

2. Choose Tool >Network Settings.

Rockwell Automation Publication 193-UM014B-EN-P December 2011 17

Chapter 2

3. If appropriate for the network, type the subnet mask, gateway address, primary/secondary server addresses, and domain name in their respective fields.

4. Click OK.

The Request History panel displays the hardware addresses of modules issuing BOOTP or DHCP requests.

5. Double-click the MAC address of the module to be configured.

NOTE: The MAC address is printed on the front of the EtherNet/IP Communications

Auxiliary. The format of the hardware address resembles: 00-0b-db-14-55-35

18 Rockwell Automation Publication 193-UM014B-EN-P December 2011

The New Entry window appears with the module’s Ethernet Address (MAC).

6. Type the IP address, host name, and a module description.

7. Click OK.

Chapter 2

Assign Network Parameters Via a Web Browser & MAC Scanner Software

8. Cycle power to the module by removing and reapplying the DeviceNet connector.

9. To permanently assign this configuration to the module: Select the module in the Relation List panel and click Disable BOOTP/DHCP.

When module power is cycled, it uses the assigned configuration and does not issue a DHCP request.

If you do not click Disable BOOTP/DHCP, on a power cycle, the module clears the current IP configuration and will again begin sending DHCP requests.

In the event that a user does not have access to a DHCP software utility, a user can assign network parameters via a web browser (e.g., Microsoft® Internet Explorer) and Media Access Control (MAC) scanner software (e.g., MAC Scanner from Colasoft® - http://www.colasoft.com/ configure the module using this method.

1. Locate and identify the MAC ID printed on the label of the EtherNet/IP Communications Auxiliary. This address has a format that is similar to: 00-0b-db-14-55-35

). Follow these steps to

2. Connect the EtherNet/IP Communications Auxiliary to the same wide area network (WAN) as your personal computer.

3. Initiate the MAC scanner software.

Rockwell Automation Publication 193-UM014B-EN-P December 2011 19

Chapter 2

4. Select the appropriate subnet to scan for available MAC addresses.

5. Scan the Subnet for all available MAC addresses.

Other Factors to Consider When Assigning Network Parameters

There are other factors to consider when assigning networks parameters, which include the:

• network isolation from or integration into the plant/enterprise network.

• network size.

For large networks, even isolated networks, it might be more convenient and safer to use a BOOTP/DHCP server rather than RSLinx software. The BOOTP/DHCP server also limits the possibility of assigning duplicate IP addresses.

• company policies and procedures associated with plant floor network installation and maintenance.

• level of involvement by information technology personnel in plant floor network installation and maintenance.

• type of training offered to control engineers and maintenance personnel.

If the Rockwell Automation BOOTP or DHCP server is used in an uplinked subnet where an enterprise DHCP server exists, a module may get an address from the enterprise server before the Rockwell Automation utility even sees the module. In this case, disconnect the uplink to set the address and configure the module to retain its static address before reconnecting to the uplink. This is not a problem if you have node names configured in the module and leave DHCP enabled.

ATT ENTI ON: The EtherNet/IP Communications Auxiliary must be assigned a fixed network address. The IP address of this module must not be dynamically provided. Failure to observe this precaution may result in unintended machine motion or loss of process control.

Duplicate IP Address Detection

When you change the IP address or connect the module to an EtherNet/IP network, the module checks to make sure that the IP address assigned to this module does not match the address of any other network device. If the module determines that another device on the network with a matching IP address, the EtherNet/IP port of the module goes into conflict mode where the Network Status LED indicator is solid red.

To resolve this conflict, use the instructions below to change the IP address of the module. Then, cycle power to the module or reset the modules by disconnecting and then reconnecting the Ethernet cable.

Two modules could possibly detect a conflict simultaneously. If this occurs, perform this procedure.

1. Remove the module with the incorrect IP address and correct its conflict.

2. Cycle power or disconnect the Ethernet cable from the second module and

reconnect it.

Behavior of Modules With Duplicate IP Addresses

Devices in conflict over an IP address behave differently depending on whether connections have been established to either of the modules and whether both modules support duplicate IP address detection.

Table 4 - Device Conflict over Duplicate IP Addresses

If then

both modules support duplicate IP address detection,

both modules support duplicate IP address detection and are started at roughly the same time,

one module supports duplicate IP address detection and a second module does not,

the first started module uses and retains its IP address. The other module will detect a conflict, give up the IP

address and enter conflict mode.

one of the modules surrenders the IP address and enters conflict mode.

the second module generally keeps its IP address, regardless of which module first obtains the IP address.

The module that supports duplicate IP address detection will detect the conflict and give up the IP address.

DNS Addressing

To further qualify a module’s address, use DNS addressing to specify a host name for a module, which also includes specifying a domain name and DNS servers. DNS addressing makes it possible to set up similar network structures and IP address sequences under different domains.

DNS addressing is only necessary if you refer to the module by host name, such as in path descriptions in MSG instructions.

To use DNS addressing, perform this procedure.

Electronic Data Sheet (EDS) File Installation

Before the EtherNet/IP Communications Auxiliary is configured to communicate on an EtherNet/IP network, it must be registered to the software that configures the network (e.g., Rockwell Automation RSLinx Classic and RSNetWorx for EtherNet/IP software). A user registers the module by installing an EDS file. The EDS file for the EtherNet/IP Communications Auxiliary can be obtained from one of two locations:

1. Assign a host name to the module.

NOTE: Contact the network administrator ro have a host name assigned. Valid host

names should be IEC-1131-3 compliant.

2. Configure the module's parameters.

3. In addition to the IP address, subnet mask, and gateway address, configure

a host name for the module, domain name, and primary/secondary DNS server addresses.
