Full title and description

IEC TS 60870-5-604:2016 — Telecontrol equipment and systems - Part 5‑604: Conformance test cases for the IEC 60870‑5‑104 companion standard. This technical specification defines a set of conformance test cases intended to verify correct implementation of the IEC 60870‑5‑104 protocol in telecontrol equipment, SCADA front‑end functions and Substation Automation Systems (SAS), to improve interoperability between implementations.

Abstract

This Technical Specification (TS) provides structured test cases and test descriptions for conformance testing of devices and systems implementing the IEC 60870‑5‑104 companion standard. The 2016 edition refines earlier test cases, resolves ambiguities and adds negative/edge test cases to enhance interoperability and operability during protocol conformance testing. The document is produced under IEC TC 57 (Power systems management and associated information exchange).

Scope

IEC TS 60870‑5‑604:2016 specifies conformance test cases for validating implementations of the IEC 60870‑5‑104 companion standard. It is intended for use when testing telecontrol equipment, substation automation components and SCADA front‑end functions to ensure protocol behaviour matches the companion standard and guidelines given in IEC 60870‑5‑6 (Guidelines for conformance testing). The TS focuses on test case descriptions (including positive and negative tests), expected behaviour and conditions for pass/fail assessment.

Key topics and requirements

• Standardized conformance test cases for IEC 60870‑5‑104 implementations (including message encoding, sequencing and error handling).
• Definitions of test preconditions, test steps, expected results and pass/fail criteria.
• Refined and additional negative test cases to check robustness against malformed, out‑of‑sequence or unexpected messages.
• Guidance aligning test cases with IEC 60870‑5‑6 conformance testing guidelines.
• Focus on interoperability and operability improvements between tested devices.

Typical use and users

Primary users are test laboratories, product development and quality teams, protocol conformance test tool vendors, system integrators and utilities implementing IEC 60870‑5‑104 in telecontrol, SCADA and substation automation contexts. The TS is used to design and execute formal conformance test campaigns and to support interoperability testing between devices from different vendors.

FAQ

Q: What is this standard?

A: IEC TS 60870‑5‑604:2016 is a Technical Specification that defines conformance test cases for implementations of the IEC 60870‑5‑104 companion standard, used to validate protocol behaviour in telecontrol and substation automation equipment.

Q: What does it cover?

A: It covers structured test cases (positive and negative), test preconditions, steps and expected results for checking correct message formats, sequencing, error handling and other protocol behaviours required by IEC 60870‑5‑104, and provides alignment with IEC 60870‑5‑6 guidance for conformance testing.

Q: Who typically uses it?

A: Test laboratories, manufacturers of telecontrol/SCADA/SAS equipment, integrators, utilities and vendors of conformance test tools use the TS to perform formal protocol conformance and interoperability testing.

Q: Is it current or superseded?

A: The 2016 edition (Edition 2.0) is the published Technical Specification dated 9 June 2016. The IEC webstore indicates a stability target (stability date) and the TS remains the reference for conformance test cases for IEC 60870‑5‑104; users should check IEC publications or national adoption listings for any more recent revisions or related series updates.

Q: Is it part of a series?

A: Yes — it is one part of the IEC 60870‑5 series (Transmission protocols). It specifically addresses conformance testing for the 5‑104 companion standard and is intended to be used alongside other parts of IEC 60870‑5 and IEC 60870‑5‑6 (conformance testing guidelines).

Q: What are the key keywords?

A: Key keywords include IEC 60870‑5‑604, IEC 60870‑5‑104, conformance testing, test cases, telecontrol, SCADA, substation automation and interoperability.
