Smart Grid Gateways

HMS Networks’ latest Ixxat SG-gateways support 4G/LTE, IIoT protocols.
HMS Networks released two Ixxat SG-gateways that feature a 4G/LTE modem for cellular connectivity as well as 4-port Ethernet switching capabilities. 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. In addition to the 4G option, multi-port versions can 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.
