Overview
IEC TR 60870-6-505:2002+AMD1:2005 CSV is the consolidated IEC technical report and user guide for TASE.2 (Telecontrol Application Service Element 2). It explains how to use the TASE.2 family of telecontrol protocols that are compatible with ISO standards and ITU‑T recommendations for exchanging real‑time power system data. This consolidated edition (Edition 1.1) includes the first edition (2002) and Amendment 1 (2005) - no separate amendment purchase is required.
TASE.2 enables standardized, vendor‑neutral communication between control centers, power plants and substations using a full ISO‑compliant protocol stack and supports both centralized and distributed architectures.
Key Topics
- Purpose and audience: Guidance for utility users evaluating, procuring and configuring TASE.2, and for vendors implementing TASE.2 in products.
- Core services covered: real‑time indications, control operations, time‑series data, scheduling and accounting, file transfer (ASCII/binary), remote program control and event notification.
- TASE.2 object model: description of server and data objects such as Association, Data Value, Data Set, Transfer Set, Account, Device, Program, Event (with cross‑references to the formal specification).
- Conformance blocks: predefined capability groups (Blocks 1–9) that organize functions like periodic power data, data set monitoring, block transfers, information messages, device/control/program management and time‑series.
- Profiles and transports: guidance on OSI and TCP/IP usage and mapping for TASE.2 deployments.
- Operational guidance: procurement advice, PICS usage, bilateral table issues, network configuration, configuration/performance/fault management, and interoperability testing.
- Security: informative recommendations and secure profile options for protecting telecontrol communications.
Applications and Who Uses It
- Electric utilities and grid operators: standardize data exchange between control centers, substations and generation sites for SCADA, EMS and market systems.
- Vendors and integrators: implement TASE.2-compliant products and ensure interoperability with other vendors.
- Procurement and engineering teams: prepare specifications, Network Interface Control Documents and conformance test plans.
- System architects: design secure, high‑availability wide‑area or local‑area telecontrol networks using ISO/TCP profiles.
