HMS Networks is now extending the Ixxat SG-gateway line with new versions including a 4G/LTE modem for cellular connectivity as well as 4-port Ethernet switching capabilities, giving users additional energy networking options for substations and power plants.
Remote access
Ixxat SG-gateways are used, in several areas of energy automation they connect energy control networks with industrial automation devices, enable remote access, act as gateways between different protocols enabling, the development of state-of-the-art IIoT applications.
Cellular communication
With the new, 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 instance, device maintenance and alarm messages (SMS or MQTT), enables the straight-forward implementation of predictive and remote maintenance applications.
Versatile 4-port switch
In addition to the 4G option, new multi-port versions of the Ixxat SG gateways are now available to securely connect networks through several independent interfaces on the 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. With 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.
