Modbus Gateway
Introduction
Modbus is an industry adopted communication protocol based on RTU, ASCII, and TCP protocols for various
applications; these three protocols are commonly used by hardware equipments in the industry, such as
DCS, PLC, HMI, power load measurement, various sensor and measuring instruments. The Modbus
Gateway is capable of implementing the Modbus environment between different hardware interfaces,
thereby streamlining the process of management and application.
Diverse Hardware Infrastructure
Modbus Gateway supports the four most commonly used hardware communication interfaces, RS232,
RS485, RS422, and Ethernet. The simple-to-use configuration software provided with Modbus Gateway can
quickly modify the hardware interface to use, and easily switch to the existing hardware communication
infrastructure.
Switching between Modbus Protocols
Modbus Gateway supports the standard Modbus protocol and is capable of converting any Modbus
protocols between Modbus TCP, Modbus RTU, and Modbus ASCII for all supported hardware interfaces, not
just limited to converting Modbus TCP into Modbus RTU/ASCII.
Modbus ID Routing
Modbus Gateway is not only capable of hardware and protocol conversions, and when a Modbus ID conflict
occurs the Modbus Gateway also supports ID routing to the existing Modbus hardware.
Modbus Gateway, Simple Integration for Complex Configurations
Modbus Gateway supports various types of hardware communication interfaces, Modbus protocol
conversion, and Modbus ID routing. Therefore the Modbus Gateway can integrate your existing and complex
Modbus hardware configuration into a simple network that can be easily managed.

Configuration and Management
Connecting to the Setup Page
There are two methods of connecting to the Modbus Gateway Configuration and Management webpage:
The first method is to use the included software tool (Devicevw.EXE) and directly select the IP address then
Click the “Browser” button. The software tool will use the default browser to open the setup page.
The second method is to launch the browser and then enter the IP address of the Modbus Gateway in the
address bar, e.g. http://192.168.50.100
The System Information page will be displayed after connecting to the Modbus Gateway homepage. Please
refer to the following for detailed descriptions of each page.
