2.4.4 Restoring the factory settings of the CPU
The "Reset to factory settings" function restores the CPU to the "delivery state".
This means that all data that was stored in internal CPU memory is deleted.
Recommendation:
Always reset a PROFINET CPU to the factory state if you want to store it or remove it for
use at a different location with a different program. Make sure that the Reset to factory
settings also deletes the IP address parameters.
Options
There are three ways to reset the CPU to the factory state:
●
Using the mode selector switch
● Using the display
● Using STEP 7 V12
Procedure using the mode selector switch
Make sure that there is no SIMATIC memory card in the CPU and that the CPU
is in STOP mode (RUN/STOP LED lights up yellow).
Perform a reset to factory settings when there is no SIMATIC memory card inserted,
as follows:
1.
Set the mode selector switch to STOP.
Initial result: The RUN/STOP LED lights up yellow.
2. Set the mode selector switch to the MRES position. Hold the mode selector switch in
this position until the RUN/STOP LED lights up in yellow for the 2nd time and remains lit
(this takes three seconds). After this, release the switch.
3. Within the next three seconds, return the mode selector switch to the MRES position,
and then back to STOP again.
Result: The CPU executes the "Reset to factory settings"; the RUN/STOP LED flashes
yellow. The yellow state of the RUN/STOP LED indicates that the CPU is reset to factory
settings and in STOP mode. The "Reset to factory settings" event is entered in the
diagnostics buffer.
Note
Make sure to set the CPU to factory state when you remove a PROFINET CPU and use it
elsewhere or put it in storage. Make sure that the Reset to factory settings also deletes the
IP address parameters.
