Beginning of June 2011 the 23rd PI Meeting took place in Lucerne (Switzerland). The yearly PI Meetings serve the exchange and transfer of know-how amongst the Regional PROFIBUS & PROFINET Associations word-wide. At the same time the PI Competence Centers (PICCs) as well as the PI Training Centers (PITCs) and the PI Test Labs (PITLs) met in Lucerne. They provide technical support and quality assurance with respect to technology and training. With more than 120 participants this was the largest meeting since the founding of the PI organization in 1995. Definitely a proof of the constantly growing interest in PROFIBUS, PROFINET and the world-wide operating PI organizations.
