IEC 60870-6-702:2014

Overview

IEC 60870-6-702:2014 is an international standard published by the International Electrotechnical Commission (IEC) that specifies the functional profile for telecontrol protocols providing the TASE.2 (Telecontrol Application Service Element 2) application service in end systems. This standard supports communication between control centre end systems and is compatible with ISO standards and ITU-T recommendations. IEC 60870-6-702:2014 defines how TASE.2 services are provided, relying on transport services tailored for different network types linking control centres.

This 2014 edition streamlines previous versions by removing less-used TASE.2 conformance blocks to improve interoperability from an application perspective. It is essential for organizations implementing telecontrol communication systems aimed at ensuring reliable and standardized data exchange in electrical and other utility systems.

Key Topics

• TASE.2 Application Service
  The standard details the implementation of TASE.2, which facilitates telecontrol data exchange, event reporting, and command issuance between two control centres over a network.

• Functional Profile Definition
  It establishes the protocol stack guidelines and conformance requirements to ensure consistency in TASE.2 service provision across different implementations.

• Transport Layer Specifications
  IEC 60870-6-702 relies on various transport profiles optimized for the specific networks interconnecting control centres, ensuring dependable protocol performance.

• Conformance and Interoperability
  Key changes focus on removing rarely used protocol features and clarifying conformance blocks, encouraging interoperable implementations aligned with international ISO and ITU-T standards.

• Scope and Applicability
  The standard applies primarily to end systems in telecontrol environments, detailing client/server capabilities, association management, data handling objects, and protocol versions.

Applications

IEC 60870-6-702:2014 is critical for industries requiring standardized telecontrol communication such as:

• Electric Power Utilities
  For SCADA systems used in monitoring and controlling substations, power generation plants, and grid management centers.

• Industrial Automation
  Providing remote monitoring and control in complex industrial processes requiring secure and interoperable communication between control centers.

• Energy Management Systems
  Facilitating data exchange and control functions within distributed energy resources and smart grid applications.

• Transport and Infrastructure Management
  Enabling telecontrol of systems such as railway signaling, water management, and other critical infrastructure requiring reliable remote control.

Implementing this standard supports enhanced system integration, reliable remote operation, and streamlined communication protocols across diverse industries.
