Optimising overall energy balance

Keywords:energy balance  optimised energy  energy management 

Energy management and responsible handling of resources is currently the number one topic in industry. In light of this, the Automation Initiative of German Automobile Manufacturers (AIDA) asked the PROFIBUS Organisation and PROFINET International (PI) to provide functions and mechanisms for PROFINET that support energy-efficient production.

In response, PI is working on a vendor-neutral energy savings profile called PROFIenergy. The objective is to develop a uniform (standardised) interface for data exchange between a controller and a wide range of devices with energy savings options. The profile will be used for exchanging data and commands, but will not contain any logic functions in terms of process control. The first release of PROFIenergy should be available by the end of this year (2009).

Energy-efficient production means more than just the use of variable-speed drives and efficient motors. The question going forward is how to selectively place complete production lines or portions thereof into standby mode during unproductive times. Ethernet networks (such as PROFINET) play a key role in this.
