Detailed Standards Coverage

IEC 62541-7:2025 – OPC Unified Architecture - Part 7: Profiles

OPC Unified Architecture - Part 7: Profiles

The latest fourth edition of IEC 62541-7:2025 provides a comprehensive model for defining and utilizing Profiles within the OPC UA ecosystem. Profiles segregate OPC UA functionality into discrete packages, each tailored for targeted testability and product conformance.

This revision shifts Profile and ConformanceUnit management to a dynamic public database, as specified in Clause 1, optimizing the lifecycle of profile updates and their accessibility for implementers. While the standard itself does not spell out individual test cases, it categorizes test types, aiding manufacturers in validating their OPC UA products—focusing resources on essential conformance areas.

What this standard covers:

• Structure and classification of OPC UA Profiles and their role in determining product feature sets
• Definitions for Profile categories, versioning conventions, and aggregation strategies
• Guidelines for conformance: choosing and demonstrating adherence to applicable Profiles

Who needs to comply?

• Automation vendors developing OPC UA-compliant devices or software
• System integrators and quality managers specifying testable product features
• Certification bodies and testing organizations

Practical implications:

• Streamlined product certification leveraging harmonized Profiles
• Simplified integration of multi-vendor OPC UA solutions
• Reduced ambiguity in product documentation and marketing

Notable changes:

• Profiles/ConformanceUnits transitioned to a managed public database, decoupled from the normative document
• Refined conventions and clearer Profile versioning, facilitating better lifecycle management

Key highlights:

• Granular definition of Profile models and categories
• Supports robust, future-proof testing methodologies
• Direct alignment with dynamic, database-driven Profile updates

IEC 62541-17:2025 – OPC Unified Architecture - Part 17: Alias Names

OPC unified architecture - Part 17: Alias Names

The release of IEC 62541-17:2025 addresses a longstanding challenge in OPC UA deployments—naming complexity and system-wide discoverability. This standard formalizes the AliasNames capability, allowing nodes within an OPC UA server to be referenced by user-defined, alternate names. The analogy is drawn to domain names and IP addresses: just as DNS alleviates network navigation, AliasNames simplify OPC node discovery across interconnected and heterogeneous systems.

What this standard covers:

• Mechanism for configuring and exposing alternate, meaningful names for any OPC UA node
• Server-side lookup methods to resolve AliasNames to their actual NodeId
• Techniques for aggregating AliasNames from multiple servers, enabling centralized discovery

Who must comply?

• Software developers of OPC UA servers and clients
• Organizations deploying advanced manufacturing systems or large-scale automation environments
• System integrators striving for streamlined, plug-and-play interoperability

Practical implications for implementation:

• Reduces engineering and integration overhead in complex environments
• Enables seamless automatic reconfiguration and system upgrades
• Empowers global discovery architectures, such as a Global Discovery Server (GDS), to aggregate and serve all AliasNames

Notable features and scenarios:

Many practical use cases are documented, such as:

• Complex configuration management across multiple engineering tools
• Aliases for system-wide tag management in cloud, on-premise, or hybrid ecosystems
• Aggregating AliasNames for non-compliant servers

Key highlights:

• DNS-like ease of node identification
• Supports global and local node aggregation
• Server and client flexibility for future extensions

EN IEC 62841-2-22:2025 – Safety for Hand-Held Cut-Off Machines

Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery - Safety - Part 2-22: Particular requirements for hand-held cut-off machines

EN IEC 62841-2-22:2025 sets forth stringent safety and operational requirements for electric hand-held cut-off machines—a segment critical to industrial fabrication, construction, and maintenance. The standards regulate machines fitted with bonded reinforced wheels (Type 41/42) or diamond cutting wheels, intended for use on metals, masonry, concrete, glass, and tiles. It specifically excludes machines convertible to grinders, saws, or tools for wooden materials (except utility cutters) and restricts the use of Type 42 wheels above 230mm diameter.

What this standard covers:

• Design requirements for safe operation: including marking, instructions, protection against access to live parts, safety guards, and overload protection
• Comprehensive mechanical, electrical, and environmental safety testing procedures
• Detailed criteria for diamond cutting wheel construction, physical guards, user instructions, and endurance under stress

Who needs to comply?

• Tool manufacturers and OEMs producing electric cut-off machines
• Safety compliance officers in industrial organizations
• Certification laboratories and testing facilities

Practical implications for implementation:

• Mandatory changes in product design, documentation, and marking for all in-scope tools
• Transition timeline recommended at 36 months post-publication (for conformity adoption)
• Detailed procedures for noise, vibration, and mechanical hazard assessment

Notable changes from previous standards:

• Supplements and modifies IEC 62841-1:2014 for this product category
• New guidance on handle design and measurement, guard thickness, flange testing, and user safety labeling

Key highlights:

• Targeted protection against mechanical, electrical, and ergonomic hazards
• Ensures safe operation at speeds up to 100 m/s and capacities up to 430mm
• Alignment with evolving EU/IEC safety best practices
