Ethernet Communications

The increase of Ethernet-based communication protocols, such as IEC 60870-5-104 paved the way for switches in local area networks of utilities. Critical applications such as IEC 61850 or SCADA data can be transmitted via fast and reliable Ethernet networks in the substation environment. Hitachi Energy's Ethernet solutions include a broad range of Ethernet LAN and WAN switches designed for utility environments. All products are environmentally hardened and are compliant with IEEE and IEC standards. They offer many features, such as fast protection schemes, redundant power supply, alarm contacts, and predictive failure notification, which enable the stepwise introduction of smart grid applications and digital substations. To support the transition from serial-based communication to packet-based technologies enabling the digital transformation, Hitachi Energy’s EDS500 Ethernet switches support protocols such as IEC 60870-5-101 or IEC 60870-5-104 for controlling the switches’ operation and monitoring its status as well as converting transparently between the protocols.
