Overview of STEP AP 242 functionalities for « PDM » interoperability

The objective of this page is to provide an overview, from the users perspective, of the STEP AP 242 functionalities for “PDM” interoperability. It is summed up according to the following paragraphs:
- Overview and illustration of capabilities
- Examples of associated use cases
- Dependencies / related standards
- Status of availability of COTS solutions
- Status of recommended practices / implementers forums

Overview and illustration of capabilities

 

The Product Data Management concepts of the Business Object Model are illustrated in the figure below

 

Examples of associated use cases

-          Interoperability between different systems

 
PDM - PDMPDM configured product structure exchange with the supply chain (full structure)
PDM - PDM
PDM configured product structure exchange with the supply chain (incremental)
PDM - CADCAD assembly structure interchange
PDM - ERP
ERP feeding (e.g Bill of Material export) with the supply chain


- Long Term Archiving and Retrieval (LTA&R):

- LTA&R of a PDM "As designed" resolved Product Structure with effectivities
- LTA&R of a PDM "As built" resolved Product Structure with effectivities

- Visualization of archived PDM configured product structure information

List not exhaustive: for more information refer to the CAX IF use cases and the STEP AP 242 use cases described by the respective industry associations.

Dependancies / related standards

STEP AP 242 PDM data model is based on the convergence of STEP AP 203 and STEP AP 214, and is also shared with STEP AP 209, AP 210, AP 233, AP 239, (list not exhaustive).
Final activities are carried out in 2013 to ensure the PDM harmonization of STEP AP 242 Business Object Model and STEP AP 239 PLCS Platform Specific Model (PSM).

Status of availability of COTS solutions

STEP AP 242 standard will support 2 implementation formats:

  • “Part 21 AIM” format, consistent with the previous implementation format of STEP AP 203 and AP 214 standards
  • “Part 28 XSD” format, based on XML, common with STEP AP 239 PLCS PSM.

Related recommended practices

In parallel of the 2 implementation formats, there will be 2 categories of PDM recommended practices for AP 242:

  • Recommended practices for PDM interfaces based on “Part 21 AIM” format

- PDM schema usage guide

- Link to the CAX-IF recommended practices page : http://www.cax-if.org/joint_testing_info.html#recpracs

  • Future recommended practices for for PDM interfaces based on “Part 28 XSD” format

- In preparation, with the planned start of the international PDM Implementer Forum in semester 1, 2014.
