MG-120

The advantage of having the MG-120 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 a hybrid network brings

the following:

■ Master mode supports up to 32 TCP slave connection requests

■ Slave mode supports up to 32 TCP master connections

Remote Management

The MG-120 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 Ethernet port. It provides a remote web management and telnet Interface for efficient remote

network management. The MG-120 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-120.

Modbus Serial Port State Monitoring

The MG-120 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-120 via the single RS232/422/485 serial interface.
