Drive technology is required for every au-tomation task: Whether it's moving, adjust-ing, positioning, conveying or storing, it all demands perfect communication between drives and the automation system. No technology in the world is used more than PROFIBUS here.

Foods are bound by especially stringent specifications for quality and traceability of the manufacturing process, including the communication technology. With PROFI-BUS, these features are of the highest pri-ority, which is evidenced by its wide distri-bution in the food industry.

Humidity measurement plays an important role in the processes of almost all indus-tries, but it's integration into fieldbus tech-nology remained disregarded for a long time. PROFIBUS provided the solution. One example is the humidity measurement carried out when producing pasta.

The use of PROFIBUS with the PROFIdrive profile is widespread in the control of packaging machines. All functions are ex-ecuted on a single bus, which considerably reduces the expenditure for engineering, hardware and training.

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.
