Electronic Keying

Electronic Keying reduces the possibility that you use the wrong device in a control system. It compares the device that is defined in your project to the installed device. If keying fails, a fault occurs. These attributes are compared.

Attribute Description

Vendor The device manufacturer.

Device Type The general type of the product, for example, digital I/O module.

Product Code The specific type of the product. The Product Code maps to a catalog number.

Major Revision A number that represents the functional capabilities of a device.

Minor Revision A number that represents behavior changes in the device.

The following Electronic Keying options are available.

Keying Option Description

Compatible Module

Disable Keying Indicates that the keying att ributes are not considered when attempting to communicate with

Exact Match Indicates that all keying attributes must match to establish communication. If any attribute

Lets the installed device accept the key of the device that is defined in the project when the installed device can emulate the defined device. With Compatible Module, you can typically replace a device with another device that has the following characteristics:

• Same catalog number

• Same or higher Major Revision

• Minor Revision as follows: – If the Major Revision is the same, the Minor Revision must be the same or higher. – If the Major Revision is higher, the Minor Revision can be any number.

a device. With Disable Keying, communication can occur with a device other than the type specified in the project.

ATT EN TI ON : Be cautious when using Disable Keying; if used incorrectly, this option can lead to personal injury or death, property damage, or economic loss.

We strongly recommend that you do not use Disable Keying. If you use Disable Keying, you must take full responsibility for understanding whether the

device being used can fulfill the functional requirements of the application.

does not match precisely, communication with the device does not occur.

Carefully consider the implications of each keying option when selecting one.

IMPORTANT

Changing Electronic Keying parameters online interrupts connections to the device and any devices that are connected through the device. Connections from other controllers can also be broken.

If an I/O connection to a device is interrupted, the result can be a loss of data.

For more detailed information on Electronic Keying, see Electronic Keying in Logix 5000 Control Systems Application Technique, publication LOGIX-

SD Card inside front panel.

Secure Digital Card

The 1756-EN4TR EtherNet/IP Bridge supports the use of a Secure Digital (SD) card to store configuration data, for example, the IP address or network communication rate for each port.

The SD card slot is inside the front panel of the module.

When the card is powered up, the device uses the configuration from the card if the configuration does not exist in the device. When a blank card is inserted, or powered up, the configuration is copied from the device to the card that was inserted.

If the module powers up with a configuration that does not match the configuration on the already inserted SD card, the configuration on the SD card is used.

If the module is already powered, and an SD card is inserted, a warning message is displayed.

TIP To see other potential error messages, see Table4 on page 25

To change these results, do one of two things. One option is to do an out of box reset on the module, if you want to use the configuration on the SD card. A second option is to modify one of the configuration settings on the device, if you want to use the configuration on the device.

Rockwell Automation Publication 1756-UM004A-EN-P - March 2019 13

Chapter 1 ControlLogix EtherNet/IP Network Device Overview

Enable/Disable Secure Digital Card

To enable or disable the SD card, use one of the following methods.

• Using a CIP Generic Message – To enable, set Attribute 4 (‘SOCKET DISABLED’) to ‘0’ (‘False’) of

Removable Media Socket Object instance (0x3A4, 932 decimal)

– To disable, set Attribute 4 (‘SOCKET DISABLED’) to ‘1’ (‘True’)

of Removable Media Socket Object instance (0x3A4, 932 decimal).

• Enable/Disable using the Add-on Profile.

The adapter supports the use of a 1784-SD1 (1 GB) and 1784-SD2 (2 GB) card. You can use third-party SD cards with the controller. You can use SD cards with as much as 32 GB of memory.

IMPORTANT Rockwell Automation does not test the use of third-party SD cards with the

device.

If you use an SD card other than those cards that are available from Rockwell Automation, unexpected results can occur. For example, you can experience data corruption or data loss.

SD cards that are not provided by Rockwell Automation can have different industrial, environmental, and certification ratings as those cards that are available from Rockwell Automation. These cards can have difficulty with survival in the same industrial environments as the industrially rated versions available from Rockwell Automation.

CIP Security

CIP Security™ is a standard, open-source communication method that helps to provide a secure data transport across an EtherNet/IP network.

The secure data transport is used between certain connected devices to help protect the devices from threats posed by unauthorized users with malicious intent.

CIP Security uses encryption to secure communication on an EtherNet/IP network, resulting in greater data integrity and confidentiality.

Rockwell Automation uses the following products to implement CIP Security:

• FactoryTalk® Policy Manager

•FactoryTalk Linx

• Studio 5000® Design Environment

• CIP Security-enabled Rockwell Automation® products, for example, the product described in this publication

(1)

For more information on CIP Security, including which products support CIP Security, see the CIP Security Application Technique, publication SECURE-

AT001.

EtherNet/IP™ networks are communication networks that offer a comprehensive suite of messages and services for many automation applications.

The following are examples of applications that use EtherNet/IP networks:

•Real-Time Control

• Time Synchronization

•Motion

This open network standard uses commonly available Ethernet communication products to support real-time I/O messaging, information exchange, and general messaging.

EtherNet/IP networks also support CIP Safety™, which makes the simultaneous transmission of safety and standard control data and diagnostics information over a common network possible.

Chapter 2 Connect to the EtherNet/IP Network

Set the IP Address

Set the IP Address with Rotary Switches

The following conditions are required to set the IP address.

Requirements

To set the IP address, have the following:

• EtherNet/IP or USB drivers that are installed on the programming workstation

• MAC ID from the device, which is on the label on the side of the device

• Recommended IP address for the device

This graphic shows the rotary switches on a 1756 EtherNet/IP communication module. The three rotary switches at the bottom of the module, labeled X, Y, and Z, can be used for setting the IP address. The rotary switch in the upper left corner of the module is reserved for future configuration.

At powerup, the module reads the rotary switches to determine if they are set to a valid number for the last portion of the IP address. Valid numbers range from 001…254.

18 Rockwell Automation Publication 1756-UM004A-EN-P - March 2019

Page 19

Connect to the EtherNet/IP Network Chapter 2

If the settings are a valid number, these conditions result:

• IP address = 192.168.1.xxx (where xxx represents the switch settings)

• Subnet mask = 255.255.255.0

• Gateway address = 0.0.0.0

TIP Some modules now provide a gateway address of 192.168.1.1 when the

network address is set with rotary switches.

• The module does not have a host name that is assigned to it, nor does it use any Domain Name System

We recommend that you set the rotary switches to a valid number before installing the module.

If the rotary switches are not set to a valid number, the module attempts to use the BOOTP/DHCP server to set the IP address.

IMPORTANT For more information on how to use the BOOTP/DHCP server to set the IP
