� 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)
