Common Techniques Used in this Manual

If you would like a manual, you can:

•download a free electronic version from the internet at www.rockwellautomation.com/literature.

•purchase a printed manual by contacting your local Allen-Bradley distributor or Rockwell Automation sales office.

The following conventions are used throughout this manual:

•Bulleted lists such as this one provide information, not procedural steps.

•Numbered lists provide sequential steps or hierarchical information.

•Italic type is used for emphasis.

•ENI/ENIW is used when information and instructions are applicable to both the 1761-NET-ENI and 1761-NET-ENIW. In cases where information applies to only one type of interface, the appropriate model and series is identified.

Product Overview

This chapter gives an overview of the Ethernet Network Interface. The following topics are covered:

•EtherNet/IP Connectivity

•Hardware Features

•Operating Modes

•Device Compatibility

•Enhancements by Series

•Ethernet Networks

•Web-Server Functionality

EtherNet/IP Connectivity	The 1761-NET-ENI and 1761-NET-ENIW provide EtherNet/IP
	connectivity for all MicroLogix controllers, CompactLogix controllers,
	and other DF1 full-duplex devices. The Ethernet Network Interface,
	ENI or ENIW, allows you to easily connect non-Ethernet controllers
	onto new or existing Ethernet networks and upload/download
	programs, communicate between controllers, and generate email
	messages via SMTP (simple mail transport protocol).
	EtherNet/IP is an industry standard open protocol which provides
	inter-device compatibility. You can exchange information with other
	Allen-Bradley Ethernet controllers (SLC, PLC, and ControlLogix) in a
	peer-to-peer relationship, so you do not need any master-type device.
	The ENI and ENIW also support an SMTP mail service that allows an
	existing controller to send email messages to any destination
	connected to the network. The email can be used to initiate the
	transmission of data or status information.

(1) Any Ethernet network activity; not necessarily to or from the ENI/ENIW.

After out-of-box power-up, the most common reason for a flashing red fault LED is because an IP address has not yet been assigned via BOOTP. Either set up a BOOTP server to assign an IP address or modify the ENI/ENIW configuration to use a specific IP address or to obtain an IP address via a DHCP server.

For more detailed information on LED operation, see Chapter 9,

Troubleshooting.

	IMPORTANT	The ENI/ENIW provides a 10/100 Base-T, RJ45
		Ethernet connector which connects to standard
		Ethernet hubs and switches via an 8-wire twisted
		pair straight-through cable. To access other Ethernet
		mediums, use 10/100 Base-T media converters or
		Ethernet switches that can be connected together via
		fiber, thin-wire, or thick-wire coaxial cables, or any
		other physical media commercially available with
		Ethernet switches. See page 2-6 for more cable
		information.

Web Server Functionality	The ENIW enhances operation with web server functionality, enabling
	it to:
	• display 40 data table values on 4 standard Data View web pages
	consisting of 7 integer and 3 floating-point values on each page,
	• display 10 user-configurable data description strings on each
	Data View web page,
	• display a diagnostic page with status and IP Address of active
	Ethernet connections (series D only),
	• password protect writable data files to prevent unauthorized
	modification, and
	• provide 10 user-configurable web page links.
	You can access information about the ENI/ENIW via your web
	browser. Simply enter it’s TCP/IP address into the address field of
	your browser.

Safety Considerations

Tests. For specific information required by EN 61131-2, see the appropriate sections in this publication, as well as the Allen-Bradley publication Industrial Automation Wiring and Grounding Guidelines For Noise Immunity, publication 1770-4.1.

Open style devices must be provided with environmental and safety protection by proper mounting in enclosures designed for specific application conditions. See NEMA Standards publication 250 and IEC publication 529, as applicable, for explanations of the degrees of protection provided by different types of enclosure.

This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D, or non-hazardous locations only. The following WARNING statement applies to use in hazardous locations.

Explosion Hazard

WARNING

• Substitution of components may impair suitability for Class I, Division 2.

• Do not replace components or disconnect equipment unless power has been switched off and the area is known to be non-hazardous.

•Do not connect or disconnect connectors or operate switches while circuit is live unless the area is known to be non-hazardous.

•This product must be installed in an enclosure. All cables connected to the product must remain in the enclosure or be protected by conduit or other means.

•The ENI/ENIW must be operated using the external power source. The DC power source switch must be in the EXTERNAL position.

•All wiring must comply with N.E.C. article 501-4(b).

Wiring

EXPLOSION HAZARD

WARNING

In Class I Division 2 applications, an external, Class 2 power supply must be used. The DC Power Source selector switch on the ENI/ENIW must be set to EXTERNAL before connecting the power supply to the ENI/ENIW.

Bottom View

•In non-hazardous locations, external power is not required. Some devices (such as a MicroLogix controller) provide power to the ENI/ENIW via a cable connected to the ENI/ENIW’s port 2. Be sure to set the DC power source selector switch to match your particular configuration, CABLE or EXTERNAL.

•Always connect the CHS GND (chassis ground) terminal to the nearest earth ground. This connection must be made whether or not an external 24V dc supply is used.

Mounting

The ENI/ENIW must be mounted in the vertical position, as shown.

Horizontal mounting is not recommended due to thermal considerations. Allow 50 mm (2 in.) of space on all sides for adequate ventilation. See page A-1 for operating temperature specification.

2-6 Installation and Wiring

When to use straight-through and cross-over cables:

•ENI/ENIW Ethernet port to 10/100-Base-T Ethernet switch cables utilize a straight-through pin-out (1-1, 2-2, 3-3, 6-6).

•Direct point-to-point 10/100-Base-T cables connecting the ENI/ENIW Ethernet port directly to another ENI/ENIW Ethernet port (or a computer 10/100-Base-T port) require a cross-over pin-out (1-3, 2-6, 3-1, 6-2).

Ethernet Cables

Shielded and non-shielded twisted-pair 10/100-Base-T cables with RJ45 connectors are supported. The maximum cable length between an ENI/ENIW Ethernet port and a 10/100-Base-T port on an Ethernet switch (without repeaters or fiber) is 100 meters (323 feet). However, in an industrial application, the cable length should be kept to a minimum.

With media converters or Ethernet switches, you can also connect to the following media:

•fiber optic

•broadband

•thick-wire coaxial cable (10-Base-5)

•thin-wire coaxial cable (10-Base-2)

Maintain ENI and ENIW Cable Connections

The unshielded twisted pair (UTP) patch cable on a switch should be labeled and treated as dedicated. Be careful when moving any cables, as port identity may be effected. If you are using a switch and must move the ENI/ENIW to a new port for any reason, power-cycle the interface. The power cycle forces a new Address Resolution Protocol (ARP) sequence which should immediately associate the ENI/ENIW’s IP address with the port it is connected to.

To help prevent problems with network communications affected by moving cables, discourage any field personnel from treating the ports of a switch as “all the same”.
