HMS Networks Ixxat smart grid gateways

Ixxat smart grid gateways from HMS Networks enable data exchange between IEC61850 or IEC60870-5-104 based energy networks and common fieldbus and Industrial Ethernet systems. Updated functions include MediaBreaker functionality and support for IEC60870-5-101, DNP3, OPC-UA and MQTT.

Ixxat SG-gateways already support secure data transmission via VPN and the IEC60870-5-104 protocol. However, according to the TSO specifications, the transmission medium must also be changed to add a further security layer and thus prevent malicious code from being passed on to the terminal device. The integration of the IEC60870-5-101 protocol enables the user to connect 101-compatible devices to the control room in accordance with the TSO specifications. Ixxat SG-gateways enable the easy ‘break’ between Ethernet-based (IEC60870-5-104) and serial (IEC60870-5-101) communication. With only one Ethernet port and one serial interface, the specific MediaBreaker version is optimally adapted to this application.

Due to the media break integration, the IEC60870-5-101 protocol is now also available via the serial interface. This enables connection of old devices to modern control rooms and controllers without having to replace them with new ones.

With support for the popular OPC-UA and MQTT standards, SG-gateways can be used to feed data from various energy and industrial networks to established services from Microsoft, Google and other providers, where the data can be evaluated and reacted upon via a secure bidirectional connection.

With the SG-gateway switch version, it is possible to connect up to four devices directly to a second Ethernet port and to distribute the communication, eliminating the need for external switches.
