Introduction The EDW-100 is an Industrial Ethernet to serial adapter or Ethernet Terminal Server. The serial interface is selectable between RS-232 and RS-422/485. The Ethernet interface is 10/100BASE-T and supports the following networking protocols: TCP, UDP, ICMP, IGMP, HTTP, ARP. Two EDW-100 can be used to provide a serial point to point link over an Ethernet network using either UDP or TCP. When using TCP the EDW-100 can be configured as client or server.

Product description The EDW-100 is an industrial Ethernet to serial interface adapter designed for harsh environments. It allows serial devices to interface through a new or existing Ethernet network. The unit can support either RS-232, RS-485 or RS-422 based protocols running at up to 115.2 kbit/s. Ethernet connection is via a standard RJ-45 port with MDI/MDI-X. The protocols used for network communication is UDP or TCP. This allows the EDW100 to be setup as a TCP-server or -client as well as an UDP unit.
Termination and fail-safe of the RS-422/485 serial interface can only be made by DIP-switches only. The local IP address of the unit can be configured by using a terminal program.

Diagnostic information The first level of diagnostic information is the status indicated by the LED´s. C:\WINDOWS\System32\telnet.exe Westermo EDW-100 login: edw100 Password: ****** Hello edw100 Welcome to Westermo EDW-100 diagnostics service (TCP Server): Listening for TCP connection on port: [9000]... The Telnet diagnostic service provide the user with information such as UDP- or TCP mode, connected or listening state (TCP) etc.
Getting started IP Address The default IP address of the EDW-100 when delivered is 169.254.100.100. Default port 9000 Default gateway 169.254.100.1 IP address configuration The IP address is configurable by the Web tool and/or by using a terminal program. Below is an description of how to configure the IP address by using a terminal program. 1. If the address is known, connect the unit from a Web browser with the address to EDW-100.
Username and Password for configuration The EDW-100 is username and password protected. These are used when connecting with Web browser during configuration and with Telnet for diagnostics. Default username: edw100 Default password: edw100 Browser Login The Webtool has two different login accounts. The first is the EDW-100 Guest account that only allows the user to read the units settings but he has no rights to configure the unit in any way.
Configuration by Web Tool The EDW-100 includes an easy-to-use Web configuration tool. The Web tool is very intuitive and includes useful help information for the configurable parameters. Connect and login to the EDW-100 with the EDW-100 Config account on the default IP address and with default username- and password combination (or your customized if configured) using a standard Web browser.
Diagnostics via Telnet The EDW-100 provides the user with diagnostics information via a Telnet connection on port 23. Information presented to the user is: … Operational mode (UDP, TCP-server or client) … Operational status (Listening for connection (TCP server), connected to host (TCP server or client), Attempting to connect (TCP client)) … The ‘Status’ LED on the EDW-100 will lit during Telnet session.
Short description of TCP and UDP User Datagram Protocol (UDP) UDP provides a connectionless datagram service. This means that the arrival of datagram’s or data packets is not controlled and the reliability of the communication is the responsibility of the application layer protocol. In this way UDP is a simpler method of communication than TCP. As data is sent and received without any established connection the data transfer is more efficient and often faster.
Short description of Modbus Modbus is a communication protocol developed by Modicon systems. The EDW-100 Modbus gateway is used for interconnecting a TCP/IP Modbus network and a serial line Modbus network (either RTU or ASCII). It permits Modbus clients (masters) on either of the TCP/IP or the serial network to connect to Servers (slaves) on the other network. In a standard Modbus network, there is one master and up to 247 Slaves, each with a unique slave address from 1 to 247.
Gateway Client mode Allows one Modbus client (master) on a serial network to connect to one or more servers (slaves) on the TCP/IP network.
Packing algorithm When data arrives at the serial port of the EDW-100 there must be one or more criteria fulfilled to trigger the EDW-100 to encapsulate the received serial data into a frame and send it out on the network. These criteria are setup using different parameters i.e. the ‘packing algorithm’. The default settings are selected to be compatible to most applications but can be optimized to the customer specific application. Detailed description can be received from the Web configuration tool.

One to many using UDP using broadcast or multicast Network Description The one to many function can be used in place of a traditional RS-422 or RS-485 multidrop application. Data entering one of the EDW-100 will be broadcast or Multicast to any other device in the broadcast or multicast group. A typical application would be a SCADA host computer communicating to a number of PLC’s.
Point to point using UDP connection Network Description In a point to point application the EDW-100 can be to replace or extend a cable link. The distance between the EDW-100 units is only limited by the size of the LAN. Data can be sent across the network using ether UDP or TCP. A typical application would be a SCADA or Data logging application interrogating a sensor or PLC. To understand the differences between a UDP and TCP please see page 16–17.
