Overview

EN 61334-4-32:1996 (IEC 1334-4-32:1996), adopted by CLC and published as SIST EN 61334-4-32:1997, defines the Logical Link Control (LLC) sublayer for Distribution Communication Protocols (DCP) used in distribution automation using distribution line carrier systems. The standard covers the services required of, or provided by, the DCP LLC entity at its logical interfaces with the application layer above and the MAC sublayer below. It is part of the EN 61334 family addressing data communication protocols over power distribution lines.

Key Topics

The standard focuses on the LLC functions and the logical interface behavior rather than physical line or MAC-layer specifics. Key technical topics and requirements include:

  • LLC service definition: the set of services and primitives exchanged between the application layer and the LLC sublayer.
  • Interface semantics: logical interface points and expected behavior at the application/LLC and LLC/MAC boundaries.
  • Frame and information handling: rules for passing data units between layers (logical data unit handling and service access points).
  • Error and flow considerations: mechanisms the LLC must support for reliable delivery, error indication, and basic flow control (as required by DCP systems).
  • Addressing and connection models: logical addressing and session/control models implied by the LLC services.
  • Interoperability guidance: requirements intended to ensure consistent implementation across distribution line carrier equipment and software.

Note: EN 61334-4-32 specifies the services and interfaces; implementers should consult the rest of the EN 61334 series for MAC layer, physical layer, and application-layer protocol specifics.

Applications

This standard is directly applicable to:

  • Electric utilities implementing distribution automation over power lines.
  • Manufacturers of distribution line carrier (PLC) modems and communications equipment.
  • System integrators and software developers building DCP-compliant control and monitoring applications.
  • Test laboratories and procurement teams specifying interoperability, conformance, and performance for distribution line carrier communication systems.

Using EN 61334-4-32:1996 helps organizations ensure consistent data link layer (LLC) behavior, improve interoperability, and support reliable remote monitoring and control of power distribution networks.
