PROFINET Conformance ClassesΒΆ

PROFINET as an open standard that defines three conformance classes with raising functionality to provide multivendor interoperability and functionality compatibility.

Within a third party certification PROFINET Modules is it ensured that a device provides the functionality of a certain conformance class. The conformance classes are divided in the categories CC A , CC B and CC C (see following figure).

The PROFINET certificate attests the norm compliance in a PROFINET network according to IEC 61158.

- Switches with IEEE802-conformity with bus-, phase- and real time clock synchronization

- IRT communication

- TCP/IP/RT and IRT redundancy

 CC C

- Comfortable device-replacement without usage of an engineering tool

- Client-functionality with MRP redundancy

 CC B  

- Conduction-bound and wireless data transfer

- Acyclic TCP/IP communication

- Alarms/diagnosis

- Definition of transfer cycle

- Automatic address resolution

- Identification & maintenance functionality

- Basic mechanism for detection of adjacent devices

- Prioritization of data transfer according to IEEE standard
