Good reasons to turn to active energy management

Good reasons to turn to active energy management
In order to achieve a coordinated and standardized approach for energy management, PI (PROFIBUS & PROFINET International) initiated development work on a solution about a year ago. As part of this solution, equipment is to be switched off not only during idle times, such as weekends and holidays. Rather, it will also be possible to switch off individual equipment components or entire systems during brief as well as unscheduled pauses. In addition measuring, transmitting and format of energy measured values are defined - important basis for an active energy management.

Thanks to the active collaboration of various companies and universities, it was possible to conclude work on the PROFIenergy definition on schedule in January 2010. Device and system manufacturers are developing the first products and will display these at Hanover Fair 2010. This is possible because of the ability to quickly and easily implement PROFIenergy into existing devices without adverse effects.

For this reason, users have begun to integrate PROFIenergy into their plant concepts based on prototype devices. Accordingly, initial references are expected before the end of 2010.

PI is supporting the dissemination of PROFIenergy through multiple activities. It is offering a White Paper entitled, "The PROFIenergy Profile", which provides a comprehensive overview of the new energy savings profile, its mode of operation, advantages, and savings potential, as well as a description of use cases. The new publication is available for download free of charge at

The fast response of PI and its member companies to urgent demands from the industrial production sector and its reliable and consistent implementation once again demonstrates the leading position of PI in industrial communication.
