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 (IEC60870-5-101/102/103/104, IEC61850 (MMS & GOOSE), DNP3.0, DLMS, Mod­bus, Pro­come, etc.), processed and trans­ferred to a Con­trol Cen- ter using IEC60870-5-104/101, 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)
