What is PROFIenergy?
PROFIenergy supports the following two functions:
●
Energy saving function
Supports targeted shutdown of loads during idle times.
●
Measured value function
Energy management is an instrument which is ideally suited to reducing energy
consumption and thereby energy costs within a company both systematically and on a
long term basis. The aim of energy management is to optimize the use of energy in a
company - from the purchasing of energy through to the consumption of energy -
economically and ecologically. The measured value function provides the measured
values required for optimization.

PROFIenergy in the motor starter
The ET 200SP motor starter supports the "Energy saving function" and "Measured value
function" for the motor current. These are identified as commands, since they trigger
reactions in the ET 200SP motor starter.
In addition, the ET 200SP motor starter also provides so-called services that provide
information on the status of the motor starter as defined in PROFIenergy. These can then be
evaluated and further processed in the user program.
Using PROFIenergy with the ET 200SP motor starter
SIEMENS provides two function blocks for using PROFIenergy:
●
PE_START_END (FB815) supports the switch to an energy-saving mode.
●
PE_CMD (FB816) supports the reading out of measured values and the switch to an
energy-saving mode
You will find further information in the document entitled "Common Application Profile
PROFIenergy, Technical Specification for PROFINET Version V1.1 Edition 2, Dec. 2013,
Order Number 3802" published by PROFIBUS International (PI).
Note
PROFIenergy is not possible with PROFIBUS interface modules.
Note
The PROFIenergy function is available with firmware version V3.3 of the interface modules.
