Full title and description
Distribution automation using distribution line carrier systems - Part 5-1: Lower layer profiles - The spread frequency shift keying (S‑FSK) profile. This publication specifies the lower-layer (physical + MAC interface) profile for spread frequency shift keying used over medium-voltage (MV) and low-voltage (LV) distribution networks to support interoperable distribution line carrier (PLC) systems for distribution automation.
Abstract
The standard defines S‑FSK modulation parameters and the required services of the physical layer entity together with the expected behaviour of the MAC sublayer so that devices from different suppliers can interoperate on power distribution networks. It assumes the electrical distribution network as the transmission medium (MV and LV) and is intended to be used in conjunction with IEC 61334‑4‑32.
General information
- Status: International Standard (published).
- Publication date: 28 May 2001 (IEC publication date).
- Publisher: International Electrotechnical Commission (IEC).
- ICS / categories: 33.200 (Telecontrol / Telemetering).
- Edition / version: Edition 2.0 (2001).
- Number of pages: 123 pages (IEC bilingual English/French edition); some single‑language national/adopted publications cite shorter page counts (typically ~65–66 pages) for the English‑only EN/BS adoptions.
Scope
Specifies the lower‑layer profile for Spread Frequency Shift Keying (S‑FSK) including modulation characteristics, timing and synchronization (slot indicators tied to mains phase zero crossings), physical‑layer service primitives and the expected interactions with the MAC sublayer. The scope covers implementation and conformance requirements for PLC systems operating on distribution networks at MV and LV levels and is intended to be used alongside higher and parallel parts of the IEC 61334 series (for example IEC 61334‑4‑32).
Key topics and requirements
- Definition of S‑FSK modulation parameters and spectral/occupancy constraints for use on distribution networks.
- Physical layer service primitives and procedures (sending/receiving, synchronization, slot timing tied to mains phase).
- Interaction rules between the physical layer and the MAC sublayer (frame length checks, timing, confirmations/indications).
- Interoperability and conformance requirements to ensure multi‑vendor equipment can operate reliably on MV and LV feeders.
- Reference to test and measurement practices necessary for device validation (implied by profile and conformance clauses).
Typical use and users
Primary users are electric utilities (distribution automation engineers), manufacturers and integrators of power‑line carrier (PLC) equipment, smart grid system architects, and test laboratories. The standard is used to design and validate physical/MAC layer implementations for automated metering, control, telemetry and other distribution automation applications over power lines.
Related standards
IEC 61334 series (distribution line carrier systems), particularly IEC 61334‑4‑32 which provides complementary higher‑layer requirements; national/adopted versions include EN/BS/EVS adoptions such as EN 61334‑5‑1:2001 and other national implementations (published 2001–2002). The document was prepared under TC 57 (Power systems management and associated information exchange).

FAQ
Q: What is this standard?
A: IEC 61334‑5‑1:2001 is an international standard that defines the lower‑layer profile (physical layer and its interface to the MAC sublayer) for Spread Frequency Shift Keying (S‑FSK) used on electrical distribution networks for distribution automation.
Q: What does it cover?
A: It covers S‑FSK modulation characteristics, physical layer service primitives and procedures, synchronization and timing (including mains‑phase slot indicators), and the expected interactions with the MAC sublayer to enable interoperable PLC communications on MV and LV networks. It is intended to be used with IEC 61334‑4‑32.
Q: Who typically uses it?
A: Utilities, PLC device manufacturers, systems integrators, test labs and smart grid solution designers use this profile to implement and validate lower‑layer behaviour for distribution automation equipment.
Q: Is it current or superseded?
A: The IEC publication date is 28 May 2001 and the IEC record shows the edition and a stability indication through 2026; users should check the IEC webstore or national standards body for any amendments, confirmations or later revisions beyond that stability date to confirm the current status.
Q: Is it part of a series?
A: Yes — it is part of the IEC 61334 series (distribution automation using distribution line carrier systems). Part 5‑1 is the lower‑layer (S‑FSK) profile; other parts of the series cover additional profiles, higher‑layer protocols and application aspects.
Q: What are the key keywords?
