Certification ofCertification ofPROFIBUSPROFIBUS DevicesDevices

PIC certification


� Why certify products?

� Certification ensures conformance with the standard and therefore interoperability

� Certified devices are more and more required by end users to meet their quality standards

� Certification process allows every vendor to benefit from the PROFIBUS experience and knowledge of the test laboratories

� Certification can be used for marketing and advertisement, because the product is marked as “Certified” in the “Electronic Product Guide” (EPG) (CD ROM or Internet)

PIC certification


PIC certification

� How to become a test laboratory?� Candidate establishes environment to perform tests as

described in the related guidelines

� Candidate prepares quality handbook according to the PROFIBUS guideline

� Candidate applies for accreditation at PNO

� Candidate is audited by an independent expert and result is reported to PI advisory board

� Board decides whether the candidate is accredited

� 1st accreditation is valid for 1 year

� Every re-accreditation is valid for 2 years

PIC certification

• Vendor applies for an ID number from PROFIBUS International (PI)for his device

• Vendor develops the PROFIBUS device and writes a GSD file

Applies for Certification test at any PROFIBUS Test Lab

Test passed ?NO
