Overview
ISO 15745-1:2003/Amd 1:2007 is an important amendment to the ISO 15745-1 standard, focused on industrial automation systems and integration. It specifically addresses the open systems application integration framework, providing a generic reference description to support interoperability and integration of automation components in open system environments. This amendment enhances the original 2003 edition by introducing additional definitions, XML schema updates, and integrity mechanisms to improve profile management and data security.
Industrial automation professionals can rely on this standard to ensure consistent and reliable integration of diverse automation applications. With increasing demands for modular and flexible automation solutions, ISO 15745-1 and its Amendment 1 help standardize communication, configuration, and profile clarity to optimize system integration and lifecycle management.
Key Topics
-
Profile Template Structure
Amendment 1 revises the master profile template to consist of three main parts:
- Header Section
- Body Section
- Optional Integrity Signature
This structure supports modularity, clarity, and security of automation profiles.
-
Integrity Signature for Profile Data
Incorporates the XML Digital Signature Recommendation (W3C REC-xmldsig-core-20020212) enabling profile documents to include an optional integrity signature. This feature:
- Helps detect unauthorized or accidental modifications
- Ensures the integrity of profile XML files (not schemas)
- Is implemented as the last child element of the XML root for consistency
-
Profile Classes and Interface Types
Defines a comprehensive set of profile classes such as Device, CommunicationNetwork, Equipment, and Human to categorize industrial components logically.
Introduces IAS Interface Types covering communication and application program interfaces to improve interoperability. Examples include:
- CSI: Communication Services Interface
- API: Application Program Interface
- CMI: Configuration Management Interface
- ESI: Engineering Support Interface
-
Profile Container Capability
The amendment adds support for combining multiple profiles into a single XML container file. This is beneficial for tools and systems that manage complex automation solutions involving multiple profiles, enabling:
- Simplified handling and exchange of profile collections
- Application of an overarching integrity signature for the entire container
-
XML Schema Enhancements
Updates the XML schema definitions for profile templates, introducing abstract types for more flexible extension and the legacy option for backward compatibility. It also specifies naming conventions for profile body types to maintain clarity and consistency.
Applications
ISO 15745-1:2003/Amd 1:2007 is fundamental in scenarios where open system application integration in industrial automation is critical. Key applications include:
-
Automation System Integration
Ensures seamless integration of devices, equipment, communication networks, and human-machine interfaces (HMIs) across multiple vendors and platforms.
-
Profile Management
Enables software tools to manage, validate, and certify automation profiles with embedded integrity signatures to maintain data authenticity and security.
-
Complex Profile Handling
Allows combining multiple related profiles into a single profile container file, simplifying deployment and lifecycle management in large automation projects.
-
Quality Assurance and Security
Helps maintain the integrity of profiles throughout their lifecycle, providing trust in configuration and operational data exchanged between systems.
-
Standardized Interface Usage
Facilitates use of standardized interfaces (API, CSI, ESI, and others), supporting modular design and flexible system architecture.
