Overview
IEC 61968-6:2015 - part of the IEC 61968 series - defines system interfaces for maintenance and construction in electric utility distribution management. It specifies the information content of message types used to support business functions such as planned maintenance, unplanned and conditional maintenance, work management, new service requests, meter installation/removal and related field activities. The standard is implementation‑independent and focuses on application integration at electric utilities to enable interoperability between distributed systems (DMS, work management, asset management, field recording, etc.).
Key topics and requirements
- Message definitions: Standardized message types including WorkRequest, ServiceOrder, MaintenanceOrder and related verbs (Annex A). These message types specify information content and usage patterns.
- Reference and information models: Uses an Interface Reference Model (IRM) and static information classes to map maintenance and construction business components (e.g., GINV, MAI, SCHD, FRD).
- XML payloads: Normative XML Schemas for message payloads are provided (Annex B) to support consistent data exchange between systems.
- UML diagrams and formats: UML diagrams and message format conventions are included to clarify structure and semantics.
- Scope of exchange: Focused on inter‑application interfaces (enterprise integration) - the standard defines what data is exchanged, not how it is transported or implemented.
- Use case alignment: Examples and end‑to‑end business cases (e.g., planned maintenance with temporary equipment, meter installation/removal, maintenance requested by field recording) illustrate practical message flows.
Applications and who uses it
IEC 61968-6 is intended for organizations and professionals involved in utility IT and operational integration:
- Utility architects and integrators implementing DMS, work management and asset management integration
- Software vendors building OMS/WMS/Field Force applications that must interoperate with enterprise systems
- System integrators and consultants delivering integration projects that require standardized message exchange
- Operations and planning teams aligning business workflows (maintenance scheduling, service orders, field crews) across systems
Typical applications include automated work dispatch, service order lifecycle management (meter work, new service), planned/unplanned maintenance coordination, and exchanging maintenance status between field systems and enterprise applications.
Related standards
- IEC 61968-1 (Interface architecture and general recommendations) - provides the IRM and general integration guidance.
- Other parts of IEC 61968 (Parts 3–9) - define interfaces for additional distribution management functions that may interact with maintenance and construction message types.
