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.

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.

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”.
