Pure Elixir implementation of IEC 60870-5-101 and IEC 60870-5-104 (Master & Slave, Balanced & Unbalanced, full Information Objects, and bidirectional File Transfer Service), modeled after lib60870-C.

Core Modules

• Shared Application Layer:
  • IEC60870.ASDU: ASDU header & payload encoding/decoding (including SQ=0 discrete and SQ=1 compact sequences)
  • IEC60870.InformationObject: Unified Information Object wrapper and codec dispatcher
  • IEC60870.IO.Monitoring: Monitoring direction Information Objects (TypeIDs 1..41, 70)
  • IEC60870.IO.Control: Control direction Information Objects (TypeIDs 45..51, 58..64)
  • IEC60870.IO.System: System Information Objects (TypeIDs 100..107)
  • IEC60870.IO.Parameter: Parameter Information Objects (TypeIDs 110..113)
  • IEC60870.IO.File: File Transfer Information Objects (TypeIDs 120..127 & domestic extension 210)
  • IEC60870.Types.CPTime: CP16Time2a, CP24Time2a, CP32Time2a, CP56Time2a
  • IEC60870.Types.BCR: 5-byte BinaryCounterReading
  • IEC60870.Types.Qualifiers: Qualifier bitfields and normalized/scaled value helpers
• IEC 60870-5-104 (TCP / TLS):
  • IEC60870.CS104.Frame: APCI I-Frame, S-Frame, U-Frame codec and stream deframer
  • IEC60870.CS104.Connection: 104 Client / Master GenServer
  • IEC60870.CS104.Slave: 104 Server / Slave GenServer with 3 redundancy modes and priority queues
  • IEC60870.CS104.MasterConnection: Peer connection response API for Slave callbacks
• IEC 60870-5-101 (Serial FT 1.2 / Virtual Bus):
  • IEC60870.CS101.Frame: FT 1.2 variable, fixed, and single-byte ACK 0xE5 codec and stream deframer
  • IEC60870.CS101.LinkLayer: Balanced & Unbalanced Primary/Secondary link state machines
  • IEC60870.CS101.Master: 101 Master GenServer (Balanced & Unbalanced multi-slave)
  • IEC60870.CS101.Slave: 101 Slave GenServer (Balanced & Unbalanced Class 1 / Class 2 queues)
  • IEC60870.CS101.Transport.VirtualBus & IEC60870.CS101.Transport.UART: Serial / virtual transports
• File Transfer Service:
  • IEC60870.FileService.Server: Slave file server (directory listing, file upload to Master, file download from Master)
  • IEC60870.FileService.Client: Master file client (request_directory/4, get_file/5, send_file/3)
  • IEC60870.FileService.TransparentFile & IEC60870.FileService.Receiver
• Observability & Metrics:
  • IEC60870.Telemetry: Telemetry event dispatcher (raw_message, asdu, connection_event, link_state, file_service)
