Tasks of PROFIenergy

PROFIenergy is a data interface based on PROFINET. This data interface allows loads to be
shut down during non-operational periods in a controlled fashion, and irrespective of the
manufacturer and device. Consequently, the process should be given only the energy it
actually requires. The majority of the energy is saved by the process, the PROFINET device
itself contributes only a few watts to the saving potential.
Figure 11-48 Energy saving during pauses with PROFIenergy
The following objectives are reached in detail by temporarily shutting down or stopping
unused drives and equipment:
● Lower energy costs.
● Reduction of thermal emissions.
● Longer service life by reducing the effective operating times.
● The drive units provide standardized consumption data for analysis.
● The PROFIenergy state of the participating devices is displayed.
● The PROFIenergy state is available with BICO interconnections for further processing,
e.g. to shutdown secondary systems that are not required.
Basics
The PROFINET devices and the power modules are shut down using special commands in
the user program of the PROFINET IO controller. No additional hardware is required; the
PROFIenergy commands are interpreted directly by the PROFINET devices.
