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
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.
