Enabling integrated energy

Connecting industrial and energy distribution equipment, Ixxat SG-gateways are the keystone to realize smart grids.



Gateway solutions for energy and smart grid systems

Data communication is the backbone of the intelligent power grid. Ixxat SG-gateways combine functionalities from RTUs, controllers and gateways and are thus the flexible solution needed for the digitalization of distribution networks. As immediately usable communication modules, they enable fast and easy connectivity by supporting energy protocols – like IEC 61850, IEC 60870, DNP, GOOSE – and fieldbus protocols.

HMS’ goal is the implementation of the necessary data communication in the most simple, fastest and secure way – for small, local distribution substations, for industrial or railway applications as well as for large power plants.
