Regional PI Associations represent PI around the world and are your perso-
nal local contacts. They are responsible for local marketing activities for purposes
of spreading PROFIBUS, PROFINET, and IO-Link, which include trade fair appearan-
ces, seminars, workshops, and press conferences, as well as public relations activities.
The PI Competence Centers collaborate closely with the RPAs and are your first point of contact
when you have technical questions. The PICCs are available to assist you in the development
of PROFIBUS or PROFINET devices and the commissioning of systems, and they provide user
support and training.
PI Training Centers support users and developers in gaining experience with the PROFIBUS
and PROFINET technologies and their possible uses. Individuals who successfully com-
plete the final exam of the Certified Installer or Engineer course receive a certificate from
PI.
PI Test Labs are authorized by PI to conduct certification tests for PROFIBUS and PROFINET.
You receive a certificate from PI for your product once it passes the test. The certification
program plays a major role in the sustainable quality assurance of products and thus
assures that the systems in use exhibit a high level of trouble-free operation and avai-
lability.
