ISO 13374-3:2012

Overview

ISO 13374-3:2012, "Condition monitoring and diagnostics of machines - Data processing, communication and presentation - Part 3: Communication," defines the communication requirements for open condition monitoring and diagnostics (CM&D) information and processing architectures. The standard enables interoperable exchange of CM&D information between software systems by specifying how data objects, reference data, data documents and processing blocks should be communicated, validated and mapped to technology-specific implementations.

Key topics and technical requirements

• Open CM&D information architecture
  • Message content must reference and validate against a defined layer 5 data document and comply with a layer 4 reference data library.
  • Specifies how receivers access reference data libraries and how library updates are published to subscribers.
• Communication initiation and message content
  • Provider initiation requirements and time-stamping must reference ISO 8601 (Gregorian calendar).
  • Message definitions must include data document references, data format renderings, compression and encryption details.
• Open CM&D processing architecture
  • Communication requirements across the processing blocks defined in ISO 13374-1 and -2 (DA, DM, SD, HA, PA, AG).
  • Emphasis on preserving data quality metadata (good, bad, undetermined) as information flows between blocks.
• Technology mapping and UML
  • Requires an ISO/IEC 19501-compliant UML model as the canonical representation of information classes and interfaces.
  • UML maps to specific technologies (e.g., XML-based web services or binary embedded communications) to support diverse runtime environments.
• Interface patterns
  • Defines provider and consumer (DataUser) services and an EntryPoint abstraction.
  • Supports synchronous (call/return) and asynchronous (publish/subscribe, sink-based) provider interfaces, including connection/notification and removal mechanisms.

Practical applications and who uses it

ISO 13374-3 is intended for:

• Software architects and developers building CM&D platforms and integration middleware
• System integrators and OEMs who need modular, interoperable CM&D components
• Maintenance engineers, reliability and asset managers implementing condition-based or predictive maintenance
• IT architects mapping CM&D models to enterprise systems for analytics, prognostics and decision support

Typical uses:

• Standardizing machine health/data exchange between sensors, edge devices and enterprise analytics
• Integrating third‑party data-processing blocks (e.g., vibration analysis, prognostics) into a unified CM&D solution
• Enabling publish/subscribe and web-service based information flows while preserving metadata and data quality

Related standards

• ISO 13374-1 (General guidelines) and ISO 13374-2 (Data processing)
• ISO 13372 (Vocabulary) and ISO 8601 (date/time format)
• ISO/IEC 19501 (UML)
• Annex A of ISO 13374-3 references IEC 62264-5 as an implementation option
