Accessories Overview Specifications


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 to easily integrate Modbus TCP to Modbus RTU/ASCII networks or DNP3 TCP/UDP to DNP3 serial networks. The MGate 5109 also supports 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 and 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 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.

A Variety of Maintenance Functions

The MGate 5109 gateways provide 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.
