Full title and description

IEC TS 60870-5-601:2015 — Telecontrol equipment and systems — Part 5-601: Transmission protocols — Conformance test cases for the IEC 60870-5-101 companion standard. This Technical Specification defines standardized conformance test cases and test conditions to evaluate implementations of the IEC 60870-5-101 companion protocol used in telecontrol, SCADA and substation automation environments.

Abstract

IEC TS 60870-5-601:2015 provides a set of test cases and related guidance to enable unambiguous, repeatable conformance testing of devices and systems that implement the IEC 60870-5-101 protocol. The TS aims to reduce the risk of non‑interoperability by prescribing how to exercise and verify protocol features, and it is intended to be used together with IEC 60870-5-101 and the test‑environment guidelines in IEC 60870-5-6. The 2015 edition resolved ambiguities from the previous edition and optimised test cases to align with IEC 60870-5-101:2003.

Scope

This Technical Specification specifies conformance test cases for implementations of the IEC 60870-5-101 companion protocol. It covers functional test cases, test stimuli and expected responses for protocol elements necessary to evaluate conformance of telecontrol equipment, Substation Automation Systems (SAS) and front‑end/SCADA functions. The TS complements IEC 60870-5-101 and refers to IEC 60870-5-6 for guidelines and conditions of the test environment. The 2015 edition addresses ambiguities in earlier publications and optimises test coverage to ensure clearer, standardised evaluation.

Key topics and requirements

• Defined conformance test cases for IEC 60870-5-101 protocol primitives and services.
• Test stimuli descriptions and expected responses to verify correct protocol behaviour.
• Guidance on test setup, test sequences and environmental conditions (references to IEC 60870-5-6 for test environment).
• Clarification and resolution of ambiguities between IEC 60870-5-101:2003 and earlier TS editions.
• Optimised and enhanced test coverage to reduce variation in test interpretation and to improve repeatability across test laboratories.
• Applicability statements describing what conformance testing can and cannot guarantee (it supports interoperability testing but does not by itself guarantee device interoperability).

Typical use and users

Primary users are manufacturers of telecontrol and substation automation devices, SCADA vendors, independent test laboratories, certification bodies, utility engineering teams and system integrators. It is used when developing, validating or certifying protocol implementations to ensure conformance with IEC 60870-5-101 and to reduce integration risk during system commissioning. Test houses use the TS to create test suites and to carry out repeatable conformance testing.

FAQ

Q: What is this standard?

A: IEC TS 60870-5-601:2015 is a Technical Specification that defines conformance test cases for implementations of the IEC 60870-5-101 telecontrol companion protocol, providing a standardised method for testing protocol behaviour.

Q: What does it cover?

A: It covers functional conformance test cases, test stimuli and expected responses for protocol elements of IEC 60870-5-101, plus guidance on test sequencing and reference to IEC 60870-5-6 for test environment conditions. It does not certify interoperability by itself but helps reduce the risk of non‑interoperability.

Q: Who typically uses it?

A: Device and equipment manufacturers, SCADA and SAS vendors, test laboratories, certification bodies, utilities and system integrators use the TS to develop and verify protocol implementations and to run conformance test campaigns.

Q: Is it current or superseded?

A: The edition in question was published on 8 October 2015 (Edition 2.0) and is published and available as the 2015 TS. It was not shown as superseded as of February 26, 2026; IEC listings indicate the TS remains the 2015 edition with a stated stability/review date in 2026. Users should consult IEC national bodies or the IEC webstore for any amendments or later revisions beyond that date.

Q: Is it part of a series?

A: Yes — it is part of the IEC 60870-5 family (Part 5: Transmission protocols) and is a Technical Specification companion to IEC 60870-5-101. It is intended to be used together with other parts of the series, notably IEC 60870-5-101 and IEC 60870-5-6.

Q: What are the key keywords?

A: Telecontrol, conformance testing, IEC 60870-5-101, SCADA, substation automation, protocol test cases, interoperability, TC 57.
