PROFIenergy

PROFIenergy
PROFIenergy is a PROFINET-based data interface for switching off consumers centrally and
in a coordinated manner during pause times regardless of the manufacturer or device type.
Through this, the process should only be provided with the energy that is absolutely
required. The majority of the energy is saved by the process; the PROFINET device itself
only contributes a few watts of savings potential.

Memory reset

Apart from a few exceptions, a "memory reset" involves clearing all internal memories and
then reading in the data on the SIMATIC memory card.
Options
You have the following options for resetting the memory of the CPU:
● Using the mode selector
● Using the display
● Using STEP 7
Procedure using the mode selector
To perform a memory reset of the CPU using the mode selector, follow these steps:
1. Set the mode selector to STOP.
Result: The RUN/STOP LED lights up yellow.
2. Set the mode selector to the MRES position. Hold the selector in this position until the
RUN/STOP LED lights up yellow for the 2nd time and remains lit (this takes three
seconds). After this, release the selector.
3. Within the next three seconds, return the mode selector to the MRES position, and then
back to STOP.
Result: The CPU performs a memory reset. During the memory reset, the RUN/STOP LED
flashes yellow. The RUN/STOP LED lights yellow when the CPU has completed the memory
reset.
