Full title and description

STB BS EN 60870-6-503-2014 — Telecontrol equipment and systems — Part 6-503: Telecontrol protocols compatible with ISO standards and ITU‑T recommendations — TASE.2 Services and protocol. This edition (based on IEC 60870-6-503:2014) specifies TASE.2 object models, services and protocol mappings (MMS/ISO/ITU‑T) for exchanging time‑critical control‑centre data across wide‑area and local‑area networks, supporting both centralized and distributed architectures and covering real‑time data, control operations, time‑series data, scheduling, accounting, remote program control and event notification.

Abstract

IEC/EN/BS EN 60870‑6‑503:2014 (TASE.2) defines a standardized method to map the Telecontrol Application Service Element No.2 (TASE.2) onto a full ISO/ITU‑T protocol stack (notably MMS / ISO 9506), enabling interoperable inter‑control‑centre communications and enterprise telecontrol for power systems and utilities. The 2014 edition clarifies object informativity and conformance blocks and aligns the specification with related functional and object‑model parts of the 60870‑6 family.

Scope

This part of IEC 60870‑6 specifies TASE.2 services and protocol mappings to a full ISO/ITU‑T stack for exchanging time‑critical control‑centre data over wide‑area and local‑area networks. It covers object models (associations, bilateral tables, data value objects, data sets, transfer sets, devices, programs, event enrollments and conditions), service semantics (real‑time indications, control operations, transfer management, scheduling, accounting), time‑series and historical data transfer, remote program control and event notification. The standard is aimed at enabling interoperable SCADA/EMS and inter‑utility communications while remaining interoperable with security profiles such as IEC/TS 62351‑4.

Key topics and requirements

• Formal TASE.2 object model (Associations, Data Sets, Transfer Sets, Programs, Event Enrollments, etc.).
• Service definitions and semantics for real‑time indications, commands, time‑series transfers, scheduling and accounting.
• Mapping of TASE.2 operations onto MMS (ISO 9506) and use of a full ISO/ITU‑T protocol stack.
• Support for centralized and distributed (virtual) control‑centre architectures and inter‑control‑centre exchange.
• Conformance blocks and testable service subsets (2014 edition clarifies informative vs normative objects and scopes for conformance).
• Security considerations and interoperability with MMS security profiles (reference to IEC/TS 62351‑4 and other security guidance).

Typical use and users

Applied by utilities, grid operators and telecommunications integrators for inter‑control‑centre communications, wide‑area SCADA and energy‑management system integration. Typical users include control‑centre engineers, SCADA/EMS vendors, system integrators, test laboratories, and cybersecurity teams responsible for protecting telemetry and control traffic. It is also used by vendors implementing TASE.2 servers/clients and by organisations performing interoperability testing and conformance assessment.

Related standards

Commonly used in conjunction with other parts of the IEC 60870‑6 family and related standards, notably IEC 60870‑6‑702 (functional profile for TASE.2 in end systems), IEC 60870‑6‑802 (TASE.2 object models), IEC/TS 62351‑4 (MMS security profiles), and ISO 9506 (MMS). It also interoperates with broader power‑systems information models and APIs (for example the IEC 61970 / CIM family).

FAQ

Q: What is this standard?

A: It is the 2014 edition of IEC/EN/BS EN 60870‑6‑503 — the TASE.2 services and protocol specification for telecontrol equipment and systems, defining how to exchange control‑centre data using an ISO/ITU‑T protocol stack.

Q: What does it cover?

A: It covers the TASE.2 object model, service semantics (real‑time indications, commands, transfers, scheduling, accounting), mappings onto MMS/ISO protocols, and mechanisms for time‑series, event notification and remote program control across wide‑area and local‑area networks.

Q: Who typically uses it?

A: Utility control‑centre engineers, SCADA/EMS vendors, system integrators, test labs and cybersecurity teams working on inter‑control‑centre communications and large‑scale telecontrol deployments.

Q: Is it current or superseded?

A: The 2014 edition (Edition 3.0) is the current IEC edition published 15 July 2014; national adoptions as EN/BS EN followed in late 2014. The IEC record lists a stability date into 2026 for this edition; consult your national body for the current national status or any later amendments.

Q: Is it part of a series?

A: Yes — it is Part 6‑503 of the IEC 60870 series (the 60870‑6 family) and is intended to work together with related parts such as 60870‑6‑702 (functional profiles) and 60870‑6‑802 (object models).

Q: What are the key keywords?

A: TASE.2, MMS, telecontrol, SCADA, inter‑control‑centre, time‑series, ISO 9506, IEC 60870.
