FEP

FEP (Front End Processor) is an embedded modularized Communications Front End Processor subsystem, that handles all communications with Remote Terminal Units (RTU) and Intelligent Electronic Devices (IED), using a number of standard protocols. It is designed to communicate with any SCADA system. The fact that FEP uses an interface allows the FEP hardware to be geographically decoupled from the Master Station and located within substations or other centrally or logistically located communication sites; thus reducing costs due to dedicated lease lines while introducing reliability. RTUs or IEDs that support standard communication protocols can transmit data with the FEP. The supported protocol library includes:

  • IEC-60870-5-101
  • IEC-60870-5-104
  • IEC-60870-6(TASE 2)
  • LABP
  • Network Time Protocol (NTP)
  • Modbus
  • DNP3
  • DLMS
  • COSEM
