Overview
EN 60870-6-701:1998 (published by CLC) is a functional-profile standard for telecontrol communications. It specifies how to provide the TASE.1 application service between two control-centre end systems, using telecontrol protocols that are compatible with ISO standards and ITU‑T recommendations. The standard focuses on functional requirements to ensure interoperable information exchange and service provision in control-centre-to-control-centre environments.
Key topics
- Functional profile for TASE.1: Defines the functional behaviour and service provision required of end systems implementing the TASE.1 application service.
- Interoperability requirements: Emphasis on compatibility with ISO and ITU‑T communication recommendations to enable consistent interaction between different vendors’ control‑centre equipment.
- End‑system responsibilities: Specifies the roles and expectations for control‑centre end systems that participate in telecontrol data exchange.
- Service provision scope: Covers the provision of application-layer telecontrol services between two control centres rather than lower-layer transport details.
- Conformance and implementation guidance: Provides the baseline functional requirements that equipment vendors and integrators can use to demonstrate conformant behaviour.
(Note: the standard text focuses on the functional profile and high‑level service definitions rather than low‑level protocol byte formats - consult the full document for implementation and conformance clauses.)
Applications
EN 60870-6-701 is relevant wherever reliable, standardized telecontrol communication is required between control centres:
- Electric power utilities - inter-control-centre data exchange for state data, control commands, and operational coordination.
- System integrators and equipment vendors - design and test end-system implementations to meet TASE.1 functional requirements.
- Telecom and SCADA engineers - plan interoperable control-centre links that follow ISO/ITU‑T‑compatible telecontrol practices.
- Standards and compliance teams - evaluate conformance of control-centre products and project specifications.
Using EN 60870-6-701 helps ensure interoperable telecontrol services, reduce integration risk, and support multi-vendor deployments in critical infrastructure systems.
