PROFIenergy

Basic information
The PROFINET devices and the power modules are turned off by special commands in the
user program of the PROFINET IO controller. No additional hardware required; the
PROFlenergy commands are directly interpreted by the PROFINET devices.
Principle of operation
At the beginning and end of pauses, the system manager enables or disables the pause
function of the system; the IO controller then sends the PROFlenergy command
"Start_Pause" / "End_Pause" to the PROFINET devices. The device then interprets the
contents of the PROFlenergy command and turns on / off.
Other PROFlenergy functions allow device information to be accessed during the pauses.
The user can use this data to transfer the "Start_Pause" / "End_Pause" command on time.
Configuration and programming
The functions can be easily integrated into existing systems. No configuration is required for
the use of PROFIenergy. However, extensions to the user program are required:
● Before enabling the Start_Pause command, the user must make sure that the system has
● A timing control for the beginning of the device pause and for punctually restarting the
● The error messages of the FB must be evaluated and the required reaction programmed

Combination of PROFIenergy and shared device
PROFIenergy is controlled by the head module. The PROFIenergy function in a shared
device is therefore only for the power modules which the head module has also subscribed
to.

the correct status for a pause.
node on pause must be programmed (depending on the required switch on times
required by the PROFINET device in question).
(for example, cancellation or continuation of additional commands to the lower-level
PROFINET devices).
