Network Basics

For Industrial Ethernet, the Ethernet Bridge functions as a slave device. In the Network 3 image shown, the computer functions as

the master industrial Ethernet device. Like the Gateway, the Ethernet Bridge can act as both a master and slave device for the various

networks .
The following table lists some of the services provided by the Ethernet Bridge:

Service

Purpose

http, Web server

Setup and configuration of the Gateway, wireless network

I/O, and Ethernet Bridge

Ping

Sends a signal to a specific device and waits for a response

to determine the communication link status

Modbus/TCP

Provides command and control functions to other industrial

devices using Modbus/TCP

EtherNet/IP™

Provices command and control functions to Allen-Bradley

deivces (both CIP and PCCC sub-protocols are supported)

The Web page interface accessed using the Ethernet Bridge provides a mechanism for setting parameters on the wireless network . While

most wireless parameters are initially configured at Banner, some of the parameters not configured include using the Gateway hardware

as a Modbus RTU master, setting up I/O maps for the Modbus master actions, backup and restoring network configurations, changing

the IP address of the Gateway, and enabling the EtherNet/IP protocol.
The Ping interface checks to see if a device is present at a particular IP address via the network . This is a troubleshooting tool .
When the DX83 Ethernet Bridge acts as the Modbus/TCP client, the user can set a polling rate and a series of reads and writes on

the Ethernet Bridge . This feature allows a network of Ethernet Bridges or GatewayPros over Ethernet with longer cable runs and larger

network sizes than would be possible with a network of standard Gateways on a Modbus 485 network .
Register maps for the Modbus TCP/IP server and EtherNet/IP slave connections are fixed, just like the register maps for the Modbus

RTU interface on the Gateway . The Modbus TCP/IP and EtherNet/IP protocols require the use of a DX83 Ethernet Bridge or a DX80

GatewayPro .

DX80 GatewayPro

A DX80 GatewayPro combines the wireless capability of the standard Gateway with the protocol converter of a DX83 Ethernet Bridge,

resulting in a device that is the master of the wireless network and a slave to an Industrial Ethernet network .
From a customer perspective, the GatewayPro is treated the same as a standard Gateway, with the GatewayPro providing Modbus/

TCP or EtherNet/IP slave access to all the information on the wireless network instead of the Modbus 485 slave interface the standard

GatewayProvides .
