SG-gateway with 4-Port Switch

Multi connectivity in one small device

The SG-gateway supports the communication protocols used in the energy sector, including IEC60870-5-104, DNP3 and IEC61850 and enables connectivity for numerous different energy devices in different networks. On top of that the simultaneously usable OPC-UA and MQTT functionality empower direct integration into the companies’ cloud-based applications.

The 4-port switch enables routing of any of the Ethernet-based protocols between 2 separate IP networks.

In addition to the IEC and DNP3 protocols, other electric equipment in the field can also be connected via Modbus TCP and RTU.

CONFIGURATION INTERFACE

The application logic can be realized on the device either using the integrated graphical web editor or by using a predefined configuration loaded to the device. The graphical web editor is a very intuitive and easy to use interface to program software applications and configure the gateway. No engineering tools are required and it can easily be accomplished by service technicians.
