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.
Ixxat SG-gateways are used in many areas of energy automation, e.g. in modern power plants and in large-scale energy consumer installations for retrofitting systems and digitalizing substations.
The SG-gateways are used for different purposes: They connect energy control networks with industrial automation devices, enable remote access, act as gateways between different protocols and thus enable the development of state-of-the-art IIoT applications
Fast cellular communication for increased data availability and insight
With the integrated 4G modem and the extensive protocol support, the Ixxat SG-gateways are ideal for easy digitalization of small, outlying energy distribution stations. The 4G CAT1 connection offers 10 Mbps downstream and 5 Mbps upstream communication with low latency, high network coverage and a universal data channel – independent of wired Ethernet, DSL or fiber optics. 4G can be used as either the main or backup communication channel. All supported IP-based protocols – including IEC 61850, IEC 60870-5-104, MQTT and OPC-UA – can be transmitted over the wireless link. The 4G modem can also be used as an independent communication channel for e.g. device maintenance and alarm messages (SMS or MQTT), enables straight-forward implementation of predictive and remote maintenance applications.
New, versatile 4-port switch versions introduced
In addition to the 4G option, new multi-port versions of the Ixxat SG gateways are now available, able to securely connect networks through several independent interfaces on data level. This simplifies data exchange between energy automation networks and industrial Ethernet systems (such as PROFINET or EtherNet/IP) as well as connection to IoT-systems and cloud applications. Each network segment is connected separately and can still exchange data with all other segments. Thanks to integrated security functions, including a firewall, the overall system is easy to design and maintain, as well as being considerably more robust and secure against unauthorized access, compared to the use of conventional gateway and switch combinations.
