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.
In addition to a transparent serial point-to-point link and ethernet to serial adapter, the
EDW-100 MG can also be configured to act as a Modbus gateway.

unit.
This enables long distance

pre-existing networks.
When EDW-100 is used
with the UDP protocol it
is also possible to communicate one to many

EDW-100 can also provide a remote serial interface
for a computer connected through a TCP/IP network
using a comport redirection software.
A COM port redirector or customer written software
can be used to create virtual COM ports. This software will redirect data, originally sent to a local COM
port, to the remote serial interface of the EDW-100.
No changes are required on the computer application
software.

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. UDP is therefore used in applications
that require efficient use of the bandwidth and also have a higher level protocol to handle
lost data.
Transmission Control Protocol (TCP)
TCP is a connection-oriented delivery service. Connection oriented means that a connection must be established before hosts can exchange data. An acknowledgement is
used to verify that the data was received by the other host. For data segments sent, the
receiving host must return an acknowledgement (ACK). If an ACK is not received, the
data is retransmitted. Flow-control between the hosts is managed by TCP. For larger
amounts of data that have to be split between packets TCP provides a method for reliably reassembling the data in the correct order. Because of the requirement to establish a
connection and acknowledge transmissions, TCP takes longer time to transmit data than
UDP and uses more bandwidth.
When delivered the EDW-100 is in TCP server mode.
TCP Server mode
This mode makes it possible to accept incoming TCP connections attempts to the
EDW-100 from an TCP client e.g. a EDW-100 in TCP client mode. Other examples
of TCP clients: Telnet client establishing a raw TCP connection, COM-port redirector
software running on a Windows PC.
TCP Client mode
This mode makes it possible to establish a TCP connection to a remote TCP server e.g.
a EDW-100 in TCP Server mode.
DSR signal rising or a powering up the unit will trigger the EDW-100 to make an
connection attempt to the specified server depending on configuration.
UDP mode
UDP is a connection less protocol sending datagram’s i.e. there are less overhead traffic
compared to TCP and no acknowledgement packets will be sent between the peer’s
during communication.
Using UDP will enable the EDW-100 to send and listen to broadcast- and multicast
messages.

6616-2202
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. The master can also write information to the slaves.
The official Modbus specification can be found at www.modbus-ida.org.
Gateway Server mode
Allows up to 16 Modbus clients (masters) on a TCP/IP network to connect to servers
(slaves) on the serial network.

Setting up the EDW-100 as a Modbus Gateway
Set the EDW-100 application mode to Modbus gateway to enable the gateway functionality. Serial settings and ip-configuration is shared whit the other application mode but the
rest of the Modbus configuration is done on the specific Modbus configuration page. To
set up the gateway it is necessary to know details about the tcp and the serial Modbus
network. Please refer to the web tool help page for more configuration details.

6616-2202
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.

Termination recommendations
The RS-422/485 line must be terminated regardless of the cable length. The termination
is ideally placed at the extreme ends of the cable see examples above. The description
of the RS-422/485 pin outs will vary between manufactures. For some brands the T+
corresponds to A T- to B, R+ to A´ and R- to B´, but other brands might use some other
naming convention. If a unit does not work it can help to swap A and B. If difficulty is
being experience contact Westermo for further guidance.

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 TCP connection, server and client

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.
Communication one to many using TCP
Network
Virtual IP
IP address:port = Com X
IP address:port = Com Y
IP address:port = Com Z
Description
Many legacy software applications do not have any facilities to directly use Ethernet but there is
a requirement to use a newly installed or existing LAN to communication to many serial devices.
This problem is solved by installing a serial port redirection software on the host PC. The redirection software works by creating virtual serial ports on the computer. The Virtual serial port can be
selected and use in the same way as a hardware based port. The serial redirection software will
encapsulate the serial data in a TCP/IP and send it to the relevant EDW-100 device. The EDW-100
will then strip off the TCP/IP frame and just forward the serial data to the target device. In th e
reverse direction the EDW-100 will encapsulate the data and the serial redirection software will
strip off the TCP/IP frame. The serial redirection software can create up to 255 serial comms ports
on a single computer.
