FAQ

What is behind the PROFINET conformance classes A, B, C?

PROFINET is divided into conformance classes (CC). The conformance classes define sensible function scopes and are thus decision-making criteria for system operators when using PROFINET components.

With prior definition of an application in a CC, the user can make a selection of components with clearly defined minimum properties.

You can find more information on the conformance classes in the PNO document "The PROFINET IO Conformance Classes - Guidelines for PROFINET IO (Order no.: 7.041)“.
