tGW -700 Series User Manual, Version 1.6, Jul. 2011 6
1. I ntroduction
Modbus has become a de facto standard industrial communication protocol, and is now the
most commonly available means of connecting industrial electronic devices. Modbus allows for
communication between many devices connected to the same RS-485 network, for example, a
system that measures temperature and humidity and communicates the results to a computer.
Modbus is often used to connect a supervisory computer with a remote terminal unit (RTU) in
supervisory control and data acquisition (SCADA) systems.
The tGW-700 module is a Modbus TCP/UDP to
RTU/ASCII gateway that enables a Modbus/TCP
host to communicate with serial Modbus
RTU/ASCII devices through an Ethernet network,
and eliminates the cable length limitation of
legacy serial communication devices. The
module can be used to create a pair-connection
application (as well as serial-bridge or serial-
tunnel application), and can then route data over TCP/IP between two serial Modbus
RTU/ASCII devices, which is useful when connecting mainframe computers, servers or other
serial devices that use Modbus RTU/ASCII protocols and do not themselves have Ethernet
capability.
The tGW-700 module features a powerful 32-bit MCU to enable efficient handling of network
traffic, and also has a built-in web server that provides an intuitive web management interface
that allows users to modify the configuration of the module, including the DHCP/Static IP, the
gateway/mask settings and the serial port settings
The tGW-700 module offers true IEEE 802.3af-compliant (classification,
Class 1) Power over Ethernet (PoE) functionality using a standard
category 5 Ethernet cable to receive power from a PoE switch such as the
NS-205PSE. If there is no PoE switch on site, the module will also accept
power input from a DC adapter. The tGW-700 module is designed for
ultra-low power consumption, reducing hidden costs from increasing fuel
and electricity prices, especially when you have a large number of modules installed. Reducing
the amount of electricity consumed by choosing energy-efficient equipment can have a positive
impact on maintaining a green environment.

1.1 Why Ethernet Solutions?
Nowadays, the Ethernet protocol has become the de-facto standard for local area networks.
Connectivity via the Internet is becoming common in many applications from home appliances,
to vending machines, to testing equipment, to UPS, etc. An Ethernet network can link office
automation and industrial control networks, access remote systems and share data and
information between multivendor machines, and it also provides a cost-effective solution for
industrial control networks.

1.2 Why Web Server Technology?
Web server technology enables configuration of the tGW-700 via a standard web browser
interface, e.g. Internet Explorer, Firefox or Mozilla, etc. This means that it is easy to check the
configuration of the tGW-700 via an Ethernet network without needing to install any other
software tools, thereby reducing the user’s learning curve.
