The MGate 5109 is an industrial Ethernet gateway for Modbus RTU/ASCII/TCP and DNP3 serial/TCP/UDP protocol conversion. All models are protected with a rugged metallic casing, are DIN-rail mountable, and offer built-in serial isolation. The MGate 5109 supports transparent mode for easily integrating Modbus TCP to Modbus RTU/ASCII networks or DNP3 TCP/UDP to DNP3 serial networks.The MGate 5109 series gateways support Modbus and DNP3 Protocol Traffic Monitor for easy troubleshooting, especially during the installation stage. Communication issues could be caused by incorrect software parameters, such as slave ID and register address, 5109 also support agent mode to exchange data between Modbus and DNP3 networks or to act as a data concentrator for multiple Modbus slaves or multiple DNP3 outstations. The rugged design is suitable for industrial applications such as power, oil & gas, and water and wastewater.

Easy Configuration via Web Console

The MGate 5109 series comes with an illustrated Quick Setup guide designed to make configuration easy. With Quick Setup, you can easily access protocol conversion modes and finish the configuration in a few steps. The MGate 5109 series also supports Auto Detection for DNP3 serial outstations, allowing the MGate 5109 to automatically acquire all outstation objects when configured as a DNP3 master.

Modbus and DNP3 Protocol Traffic Monitor

The MGate 5109 series gateways support Modbus and DNP3 Protocol Traffic Monitor for easy troubleshooting, especially during the installation stage. Communication issues could be caused by incorrect software parameters, such as slave ID and register address, or incorrect command configuration. With Modbus/DNP3 Protocol Traffic Monitor, you can check the captured data and easily identify the root cause.

Variety of Maintenance Functions

The MGate 5109 series gateway provides a web console and Telnet console for remote maintenance. Encryption communication functions, including HTTPS and SSH, are supported to provide better network security. In addition, firmware log functions are provided to record connection events and Modbus maintenance events. Users can review log data remotely through the web console.

Key Considerations When Upgrading DNP3-Supported Communications

DNP3 (Distributed Network Protocol) is a very popular communications protocol in telemetry systems, with a large number of field devices and control equipment using it. SIs often consider serial device servers, protocol converters, or embedded computers to handle DNP3-related protocol conversions and communications. But, due to their unfamiliarity with the variety of protocols currently in use, SIs are often at a loss to know which option is best suited for their network. In this white paper, we look at the various options available to upgrade serial-based DNP3 devices to Ethernet-based networks and expand on some of the key issues that need to be considered beforehand.
