IEC 62714-3:2017

Overview

IEC 62714-3:2017 is an important international standard published by the International Electrotechnical Commission (IEC) that defines the engineering data exchange format specifically for industrial automation systems engineering. This part, titled "Automation Markup Language - Part 3: Geometry and Kinematics," focuses on how geometry and kinematics information can be integrated and exchanged between engineering tools within plant automation environments using the Automation Markup Language (AML).

This standard addresses a critical need in industrial automation for a unified format that ensures consistency, accuracy, and interoperability when sharing geometric and kinematic data across different systems and engineering tools. The format primarily leverages AML alongside integration with COLLADA documents, enabling detailed representation and manipulation of 3D models, spatial frames, joints, kinematic models, and articulated systems.

Key Topics

• Data Exchange in Industrial Automation
  IEC 62714-3:2017 provides a robust framework for exchanging detailed geometric and kinematic data, which are essential for designing, simulating, and operating automation systems.

• Automation Markup Language (AML) Extensions
  The standard extends AML libraries by adding new roles, interfaces, and attributes necessary to define and connect geometry and kinematics data, including the AutomationMLBaseRoleClassLib and AutomationMLInterfaceClassLib.

• Integration with COLLADA
  COLLADA is the industry-standard XML format for 3D models. This standard details how to integrate COLLADA documents into AML, allowing the inclusion of complex visual scenes, frames, and kinematic descriptions within the AML data exchange framework.

• Frame Attribute and Object Attachment
  Definition and usage of the Frame attribute enable spatial referencing of objects. Attachment methods specify how different AML objects can be linked or connected spatially, which is key for modeling components like robots, linear units, grippers, and workpieces in an automation system.

• Kinematic System Modeling
  The standard includes informative annexes illustrating how to model entire kinematic systems and their combinations (e.g., robots with linear axes or grippers) in AML, blending CAEX and COLLADA documents for comprehensive automation modelling.

• Referencing Methods for Geometry and Kinematics
  Various referencing techniques are covered, such as explicit and implicit references within AML documents, to handle complex hierarchical and modular engineering data structures effectively.

Applications

IEC 62714-3:2017 applies to a wide range of industrial automation scenarios, including:

• Robotics Engineering
  Modeling and sharing detailed kinematic chains of robots with accurate geometric data to facilitate offline programming, simulation, and control integration.

• Plant Automation Design
  Enabling seamless data exchange between CAD, simulation tools, and control engineering systems to improve the design of automated manufacturing cells and complete plants.

• Machine Integration
  Defining interfaces and spatial relationships between machine components for automated assembly lines where complex mechanical interactions and movements need precise coordination.

• Digital Twins and Virtual Commissioning
  Supporting the growth of digital twin technology by providing detailed geometry and kinematics data essential for realistic virtual commissioning and predictive maintenance.

• Interoperability Across Toolchains
  Facilitating multi-vendor and cross-disciplinary collaboration by standardizing the way geometry and kinematics data are structured and exchanged in heterogeneous industrial environments.
