Moxa Launches Modbus-to-DNP3 Gateway to Accelerate Project Deployments

Brea, California, Sep 6, 2016—Moxa’s newly launched MGate 5109 is an industrial Ethernet gateway with an all-in-one design that supports multiple combinations of Modbus RTU/ASCII/TCP to DNP3 serial/TCP/UDP conversions. As all of these conversions can be performed within a single model, the need to purchase, deploy, and set up multiple devices to perform all of these conversions is eliminated.

Moxa MGate series web console walks users through the entire setup process in just a few simple steps, giving engineers the convenience of only needing a computer equipped with an Ethernet port and web browser to handle configuration and setup.

Auto Detection for DNP3 Objects
The MGate 5109 can also auto detect the points index for each binary input, binary output, counter, analog input, and analog output. Instead of having to manually input the number from the product’s user’s manual, which will typically take longer and therefore increase operational costs, users can simply click “Auto Detection” and the MGate’s web console will automatically input the settings.

Monitoring and Troubleshooting Made Easy
The MGate 5109 has multiple built-in tools to simplify troubleshooting. Users can start by monitoring the system status by using the diagnose function, which detects the communication status of the DNP3. Next, the diagnose function can detect the status of each of the points, including on/off and analog values. Last, the MGate 5109 supports a protocol traffic monitoring tool, which provides the Modbus RTU/ASCII or DNP3 with data passing through the gateway on the serial network. Rather than simply echoing the data, it presents the data in an intelligent, easy-to-understand format with clearly designated fields, including source, type, destination, contents, as well as several other fields. Events can be filtered in different ways and the complete log can be saved as a file for later analysis.

Key Features

  • Supports Modbus master/slave and DNP3 master/outstation
  • Complete diagnosis information for maintenance
  • Embedded Modbus and DNP3 serial traffic monitoring
  • Serial port with 2 kV built-in isolation protection
  • Built-in Ethernet cascading for easy wiring
