PI White Paper: Semantics for PI Application Profiles


The intelligent manufacturing networks of digital factories will only become reality with machine - processable, standardized information, because they have to interact over different communication technologies, different companies and even across industry boundaries. PROFIBUS & PROFINET International (PI) sees its role in creating the necessary basis for this fact, especially in view of Industrie 4.0.

This has been accomplished by providing device-related expertise for PI technologies – for instance, in the form of parameters in the open device profiles or other specifications for the application layer, like for an asset management record. However, in order for these to be use d as the basis for a machine-processable flow of data across the various systems – from sensor to cloud – the data that is already available today must be transformed into clearly usable information by means of semantic standards.

ECLASS e.V. is playing an increasingly important role in industrial automation and especially for Industrie 4.0. In cooperation with ECLASS e.V. existing PI specifications will be expanded by semantic identifiers. In a first step, PI application profiles (e.g., PA Profile) were selected, having the best preconditions for this endeavor.

The results form a significant basis for the automated interaction of various systems and components from different manufacturers are essential for business processes to run optimally between end users, suppliers, customers, etc. in systems of the Industrie 4.0 generation.
