1.4 PROFIenergy
What is PROFIenergy
PROFIenergy is a manufacturer-independent profile on PROFINET. The profile
supports the shutdown in idle times (energy-saving function), measurement of
the energy flow (measurement function) and the status function that is used
to export the current status conditions and other information on PROFIenergy.
PROFIenergy uses field-tested PROFINET mechanisms ensuring rapid and
simple implementation
Origination
Both standards and regulations are increasingly focussing on environmental
protection and energy management as well as the desire to save energy costs
in a production plant and thus secure a sustainable competitive advantage.
As a result, the aim of industry is to save energy and to actively reduce CO2
emissions. The careful use of valuable resources means that the manufacturer-
nonspecific PROFIenergy profile defined on PROFINET makes an active contri-
bution to environmental protection.
PROFIenergy (Version1.0) in ET200pro motor starter
PROFIenergy allows consumption data from the equipment to be read in
a standardized format. This data is recorded during operation and displayed
on control device, for example, or transferred to higher level energy manage-
ment software packages. This ensures that these measurements, as currently
present in motor starters, are available to the user for onward processing in
a standardized, manufacturer-nonspecific defined format and structure.
These PROFIenergy functions therefore form the basis for an active load and
energy management system in ongoing operations.
The system and device manufacturers provide the user with function blocks
for PROFIenergy and implement the relevant commands and status functions
in the field devices. The plant and machinery engineer and the plant operator
coordinate the switch-on and switch-off sequences as before, as well as the
enabling signals for the process. The control stores which components are
switched off with which pause type. The system operator does not need to
get involved with the technology in detail.
