Overview
EN 60870-6-802:2014 (IEC 60870-6-802) - also known as TASE.2 Object models - defines object models and data mappings for exchanging time‑critical telecontrol data over wide‑area and local‑area networks using a full ISO‑compliant protocol stack. The standard supports both centralized and distributed architectures and covers the exchange of real‑time data indications, control operations, time‑series/schedule data, accounting information, remote program control and event notifications. This edition clarifies conformance by making several previously informative objects normative and by scoping out certain conformance blocks.
Key topics and requirements
- TASE.2 object models: standardized models such as IndicationPoint, ControlPoint, Protection Equipment Event, Device Outage and InformationBuffer for consistent data representation.
- MMS (ISO 9506) mapping: mappings of object models to MMS types to ensure interoperable data exchange over ISO/ITU stacks.
- Real‑time and scheduled data: provisions for real‑time indications, control commands, time series and scheduling data exchange.
- Event and program handling: event notification models and remote program/control mechanisms (with selected object/service scope clarified in this edition).
- Conformance and scope changes: Accounts, Programs, Event Enrollment and Event Condition objects have been elevated to normative status; some TASE.2 conformance blocks (e.g., blocks 6–9) are out of scope in this edition.
- Network applicability: designed for both wide‑area networks (WAN) and local‑area networks (LAN) using an ISO‑compliant protocol stack compatible with ITU‑T recommendations.
Applications
EN 60870-6-802:2014 is intended for systems where secure, interoperable telecontrol and supervision are needed:
- Utility SCADA and Energy Management Systems (EMS) for power system monitoring and remote control
- Cross‑control‑center data exchange and inter‑utility interfaces
- Protection equipment event reporting and outage management
- Metering, scheduling and accounting data exchange between control centers
- Integration layers for distributed automation and remote program control
Who should use this standard
- Control‑center architects and SCADA/EMS integrators
- Telecontrol protocol implementers, equipment vendors and firmware developers
- System integrators working on utility interchanges and wide‑area telecontrol
- Compliance and testing laboratories validating TASE.2 interoperability
