Electrical Harness Interoperability WG Electrical Harness Interoperability WG
 Last update: February 2013

The objective of the “Electrical Harness interoperability” working group is to ensure the coordination and the consistency of all ASD standardisation activities related to “electrical harness” information interoperability. This working group is part of the ASD SSG “PLM interoperability” domain. 

 

The recommendations of the working group cover product information interoperability for the full life cycle of the electrical harnesses, from specifications to maintenance. This covers all the interoperability functions based on open standards, such as:

  • integration between heterogeneous authoring applications (upstream, downstream, ...)
  • communication with the extended enterprise or with the customers,
  • visualisation,
  • long term archiving and retrieval,
  • data quality
  • and migration.

The first version of this web page has a limited scope, and will be regularly updated.

Scope
 

The following figure, based on a generic life cycle of an Aerospace and Defence product, describes the different Electrical models with associated information characteristics.

ASD SSG 5 years vision
 

The 5 years vision of the ASD SSG “Electrical harness interoperability” working group is set up on three principles:

1)      Electrical harness interoperability ensured by the availability of use cases, ISO information model, recommended practices and CAD vendors testing.

 The operational use of Electrical harness interoperability standards by the A&D industries requires the availability of:

  • Use cases for Electrical harness interoperability, supporting A&D business needs and priorities,
  • International standards for Electrical harness Information models (Cf. principle 2)
  • International and/or European recommended practices based on use cases, detailing the implementation of the ISO Electrical harness information model,
  • Interoperability testing of the standardized Electrical harness interfaces and services of the different PLM vendors, through the participation in the CAX Implementer Forum.

2)      Reliable ISO Information models for Electrical harness interoperability.

The ASD SSG recommends the choice of a limited number of core harmonised ISO 10303 Application Protocols, having interdependencies properly specified and managed through the time. The STEP AP 212 standard is not planned to be enhanced. Therefore, the target of the ASD SSG is to prepare the extension of the AP 242 edition 2 to the electrical harness domain, taken into account the harmonisation / complementarities with the ISO 10303 STEP standards:

  • STEP AP 210 “Standard for Electronic Assembly Interconnect and Packaging Design”
  • STEP AP 233”Systems Engineering”,
  • STEP AP 239 “Product Life Cycle Support”
  • And the strong contribution of the VDA 4968 VEC specification.

Planned operational use of ISO standards for PDM interoperability and long term archiving:

N1: No ISO standard available for the short and mid term covering the Electrical harness semantic. Trial use of VDA 4968 VEC KBL and VEC specifications is being undertaken.

N2: Solution based on the preservation of the CAD 3D external shape of the harnesses with annotations.

 

3)    Contribution to the development and use of the NAS / EN 9300 4XX family, for Long Term Archiving and Retrieval of Electrical harness information.

The ASD SSG strategy relies on the joint AIA – ASD Stan LOTAR international project to develop the NAS / EN 9300-4XX standards for electrical harness.

The LOTAR standard will define Process, use cases, validation and verification rules for long term archiving and retrieval of electrical harness information.
