1.2 Product Description

Standard Modbus TCP/RTU/ASCII Network Integration

PLANET MG-11x 1-port RS232/422/485 Modbus Gateway Series supports the standard Modbus Protocol, which makes it possible for converting any Modbus Protocols between Modbus TCP, Modbus RTU, and Modbus ASCII for all supported hardware interfaces. Its serial protocol can be used for industrial automation where SCADA or HMI system is in place. Moreover, its network integration can be upgraded from the SNMP network to the automated Modbus TCP network, which brings interconnection over Ethernet longer distances, thus making a network infrastructure more flexible.

A Conversion Bridge for Flexible Network Deployment

The MG-11x Series can be a conversion bridge between the equipment with the Modbus RTU/ASCII Protocol and the administrator workstations that run the Modbus TCP/IP Protocol. The RS232/422/485 serial interface of the MG-11x Series provides the Modbus RTU/ASCII operation mode and various baud rate options to meet the demand of integration between the Modbus TCP/IP Protocol, Modbus RTU Master/Slave Protocol and Modbus ASCII Master/Slave Protocol.

The advantage of having the MG-11x Series is to assist users to build an environment between the Modbus TCP Protocol and the Modbus RTU/ASCII Protocol easily, thus offering an application solution to the control equipment without Ethernet ports, and the control equipment can only control through a PC workstation or control panel.

In addition, the effective integration solution of Modbus Ethernet devices, Modbus serial equipment or multi Modbus master / slave in an hybrid network brings the following:

■ Master mode supports up to 32 TCP slave connection requests
■ Slave mode supports up to 32 TCP master connection requests

Differences between Serial Devices and Modbus Gateway

Serial Devices Server

Modbus Gateway

Remote Management

The MG-11x Series makes the connected Modbus RTU/ASCII equipment become IP-based facilities and is able to connect to the Modbus TCP/IP network via its R232/422/485 serial interface and 10/100BASE-TX RJ45 or 100BASE-FX Ethernet port. It provides a remote web management and telnet interface for efficient remote network management. The MG-11x Series also provides PLANET Modbus Gateway utility tool and supports PLANET Smart Discovery utility to help network administrator to easily get the current IP subnet address information or change the IP subnet address setting of the MG-11x Series.

Remote Management

Modbus Serial Port State Monitoring

The MG-11x Series shows the details of the total bytes transmitted and received on the RS232/422/485 serial interface, and the detailed total number of frames transmitted and received on the remote web/telnet management interface. This function allows network administrator to check the status and statistics of the MG-11x Series via the single RS232/422/485 serial interface.

Fiber-optic Link Capability Extends the Range of Network Deployment (Only MG-115A)

The maximum distance between two IP devices via Ethernet UTP cable is 100 meters. To flexibly extend the deployment range of Modbus gateway, the MG-115A's SFP slot supporting 100BASE-FX SFP modules and more can reach a transmission distance of up to 120km.

Easy Chassis Installation (Only MG-110/115A)

The MG-11x Series can be used as a stand-alone unit or as a slide-in module to the PLANET Media Converter Chassis (MC-700 and MC-1500 chassis series). The media chassis can assist in providing DC power to the MG-11x Series and can be DIN-rail or wall mounted for efficient use of cabinet space, without the need of replacing the existing serial equipment and software system.

3.5.2 Searching Modbus Gateway

First click "Add Device" and then click "Search" if Serial Server has access to network, as shown below.

This section introduces the configuration and functions of the Web-based management from Modbus Gateway.

About Web-based Management

The Modbus Gateway offers management features that allow users to manage the Modbus Gateway from anywhere on the network through a standard browser such as Microsoft Internet Explorer.

The Web-based Management supports Internet Explorer 7.0. It is based on Java Applets with an aim to reduce network bandwidth consumption, enhance access speed and present an easy viewing screen.

By default, IE7.0 or later version does not allow Java Applets to open sockets. The user has to explicitly modify the browser setting to enable Java Applets to use network ports.

The Modbus Gateway can be configured through an Ethernet connection, making sure the manager PC must be set to the same IP subnet address with the Modbus Gateway.

For example, the default IP address of the Modbus Gateway is 192.168.0.100, then the manager PC should be set to 192.168.0.x (where x is a number between 1 and 254, except 100), and the default subnet mask is 255.255.255.0.

If you have changed the default IP address of the Modbus Gateway to 192.168.1.1 with subnet mask 255.255.255.0 via console, then the manager PC should be set to 192.168.1.x (where x is a number between 2 and 254) to do the relative configuration on manager PC.
