Specialized communication unit for electrical facilities


iGWlite is a specialized communication unit for electrical facilities that require data conversion between different protocols.

Data from multiple devices (meters, protection relays, and other IEDs) may be ac- quired using field protocols (IEC608705101/102/103/104, IEC61850 (MMS & GOOSE), DNP3.0, DLMS, Modbus, Procome, etc.), processed and transferred to a Control Cen- ter using IEC608705104/101, IEC61850, DNP3.0, and Modbus RTU/TCP protocols.


Product highlights

  • From meter data concentration to protocol conversion, iGWlite can act in any kind of control or automation system, specially in generation plants or high voltage substations, using any kind of communication protocol and media.
  • Availability of a wide range of protocols including IEC60870-5-101/102/103/104, IEC61850, Modbus RTU/TCP, JBUS, DNP3.0, DLMS, Procome and Profibus DP.
  • Multiple communication media options, including serial ports (RS232/RS485/fiber optic) and Ethernet (10/100BaseTX with RJ45 and FX100 fiber optic with SFP modules or ST/SC connector).

Technical features

  • Multiple simultaneous control centers, with one or more com- munication protocols.
  • IEC 62351 Cyber security compliance (TLS/SSL, VPN, SSH, HTTPS, RBAC, ACL).
  • IEC 61850-3 EMC compliant.

  • IEC 61131-3 PLC automation programming.

  • IEEE 1588 and NTP time synchronization.

  • Microseconds timestamp resolution and high accuracy RTC with 1.5ppm time drift.

  • Ethernet interface with independent MAC address and multiple IP address configuration.

  • Support for VLAN and VPN connections.

  • Transparent TCP bridging.

  • iGWlite comes with a full range of protocols including IEC 60870-5-101, IEC 60870-5-104, IEC61850 MMS client/server, IEC 61850 GOOSE publisher/subscriber, Modbus RTU/TCP, DNP3.0 (serial and TCP), among others, in order to ensure the communication with new and legacy IEDs and SCADA master stations.

  • Meter connection with DLMS, IEC 62056-21 and IEC 60870-5- 102 protocols.

  • Protection relay connection with IEC 60870-5-103, SpaBus, Mlink, Procome, Profibus and IEC 61850 (MMS and GOOSE) protocols.

  • Device Alarm relay (optional)
