INTRODUCTION | This manual is to be used with a ConneXium™ ETG100 with firmware |
| version 2.0 or higher. For installation information, see the installation guide. |
| The ETG100 is a communications device that provides connectivity |
| between Ethernet (Modbus TCP/IP) and serial line devices, allowing |
| Modbus TCP/IP clients to access information from serial slave devices. It |
| also allows serial master devices to access information from slave devices |
| distributed across an Ethernet network. |
Supported Ethernet Protocols | The ETG supports the following Ethernet protocols: |
| • Modbus TCP/IP: Modbus TCP/IP is a combination of the Modbus |
| protocol, which provides |
| and TCP/IP, which provides communications over an Ethernet |
| connection. Modbus TCP/IP is used to exchange data between the ETG |
| and other compatible Modbus TCP/IP devices via TCP port 502. |
| • Hypertext Transfer Protocol (HTTP): HTTP is a network protocol that |
| handles the delivery of files and data on the World Wide Web. It |
| provides web server functionality via TCP port 80. Remote configuration |
| of the ETG and the viewing of diagnostic data is possible using a web |
| browser. |
| • File Transfer Protocol (FTP): FTP is a network protocol that provides |
| the ability to transfer files over the Internet from one computer to |
| another. FTP is used to transfer firmware updates to the ETG via TCP |
| port 21. |
| • Simple Network Management Protocol (SNMP): Based on MIB2 |
| format, SNMP provides the ability to store and send identifying and |
| diagnostic information used for network management purposes via UDP |
| port 161 . |
| • Address Resolution Protocol (ARP): ARP is used to convert IP |
| addresses to Ethernet addresses. ARP requests are sent by the ETG to |
| determine if its address is a duplicate IP address (see “Duplicate IP |
| Address Detection” on page 6). |
