The well-conceived and widely-established certification concept of PI (PROFIBUS & PROFINET International) has contributed significantly to today's international acceptance of PROFINET.
Meanwhile, the expenses for creating test specifications and test cases and for implementation in test systems have amounted to more than EUR 0.5 million. As a result of these investments and the dedicated efforts of the working groups, certification now covers the entire basic functionality of PROFINET. This extends from IO devices with RT functionality and IRT functionality to IO controllers. Since the complete certification offer is now available and no additional costs are expected to be incurred, the Board of Directors has decided to abolish the certification fees for members, effective January 1, 2010.
With conclusion of the work on certification of PROFINET IO controllers, a final important step in the certification program was achieved. The controller certification is based on test scenarios for interoperability tests. Products that have passed the test receive certificates valid for 3 years.
Further activities pertain to the certification of supplemental functions, such as the parameter server. In the PROFIBUS and PROFINET world, this provides for uncomplicated access to the so-called individual parameters, thus device and/or manufacturer-specific field device data. This is especially critical for seamless device replacement. In order for the user to count on a high quality level in this case as well, a certification for the parameter server is also available effective immediately.
