OPC Foundation: Kick-Off Working Group "Weihenstephan Standards"

Kick-Off Working Group "Weihenstephan Standards" for the Food and Packaging Industry on Feb 27th 2024

This Joint Working Group with WS Industrial User Group, VDMA, and OPC Foundation will develop an OPC UA Information Model for the food and packaging industry based on the Weihenstephan Standards (WS).

29 Feb 2024 - UT-F190-B40-2V1D-FR from Pepperl+Fuchs


The working group was initially created in 2019 and developed the Companion Specification OPC 40600 - OPC UA for Weihenstephan Standards. A significant focus of CS 40600 was backward compatibility with the models of the Weihenstephan Standards, which have been used in the industry for many years. 

The reactivated working group will develop a new specification with a "real" type-based OPC UA information model. Backward compatibility is no longer a requirement. 


The Weihenstephan Standards are domain-specific communication interfaces for the food and packaging industry. One of the strengths of the Weihenstephan Standards is their explicit focus on individual domains. The Weihenstephan Standards are currently available for the following five domains: 

  • WS Pack: Machines and equipment in filling and packaging plants
  • WS Food: Machines and equipment in the meat-processing food industry
  • WS Bake: Machines and equipment in the bakery industry
  • WS Brew: Batch-oriented production within beverage-producing companies, especially breweries
  • WS Sweets: Machines and equipment in confectionery production

For each domain, the Weihenstephan Standards provide domain-specific recommendations for data evaluation and reporting on higher-level IT systems.
