Smart grid gateways
03 March 2021
HMS NETWORKS is 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.
With the new integrated 4G modem and extensive protocol support, the Ixxat SG-gateways are said to be ideal for easy digitalisation 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.
