Overview

EN 60870-6-2:1995 (also published as IEC 870-6-2) is a European/International standard that addresses the use of basic communication standards for telecontrol systems. It focuses on the OSI reference model layers 1–4 (Physical, Data Link, Network, Transport) and describes the role and functions each layer must perform to support telecontrol protocols that are compatible with ISO standards and ITU‑T recommendations. This section of the EN 60870-6 series helps ensure interoperability and reliable communication in telecontrol and telemetering environments.

Key Topics and Requirements

• Scope of layers 1–4: Clarifies responsibilities of the Physical, Data Link, Network and Transport layers for telecontrol systems.
• Mapping telecontrol functions to OSI services: Describes how telecontrol communication needs (e.g., command, status, telemetry) are provided by each OSI layer.
• Interoperability and compatibility: Emphasizes alignment with ISO and ITU‑T recommendations so devices from different vendors can interoperate.
• Functional roles: Defines expected functions such as framing, addressing, error detection and correction, flow control, connection establishment and release for the lower OSI layers.
• Implementation considerations: Provides guidance on selecting and applying base standards for physical media, link protocols, network routing/addresses and transport services to meet telecontrol performance and reliability needs.
• Reference to basic standards: Points implementers to relevant ISO/ITU‑T base standards as the foundation for telecontrol protocol stacks.

Applications and Who Uses This Standard

• Utility and infrastructure SCADA/telecontrol systems (electricity, water, gas) requiring standardized communication layers.
• Telemetry and remote supervisory control engineers specifying communication stacks.
• SCADA vendors and system integrators implementing interoperable telecontrol protocol stacks.
• Telecommunications engineers ensuring network and transport services meet telecontrol reliability and latency requirements.
• Standards bodies and compliance teams aligning product designs with ISO/ITU‑T and IEC/EN guidance.

Practical benefits include improved interoperability between devices, clearer guidance for selecting physical and link-layer technologies, and a consistent approach to error-handling and transport services for telecontrol applications.

Related Standards

• EN/IEC 60870‑6 series (telecontrol protocols compatible with ISO/ITU‑T)
• ISO and ITU‑T recommendations for OSI layers (as referenced in the standard)
• Other IEC telecontrol standards used for higher-layer application profiles and SCADA-specific message models
