Restoring The Factory Settings Of The Cpu - Siemens SIMATIC S7-1500 Manual

2.6.4

Restoring the factory settings of the CPU

The reset to factory settings function restores the CPU to the factory settings. The function
deletes all information that was stored internally on the CPU.
Note
If you want to remove a PROFINET CPU and use it elsewhere with a different program or
put it into storage, we recommend that you reset the CPU to its factory settings. Remember
that the Reset to factory settings function also deletes the IP address parameters.
Options
You have the following options for returning the CPU to the factory settings:
● Using the mode selector
● Using the display
● Using STEP 7
Procedure using the mode selector
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 as follows:
1. Set the mode selector to STOP.
Intermediate result: The RUN/STOP LED lights up yellow.
2. Set the mode selector to the MRES position. Hold the mode 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 executes the reset to factory settings, during which time the RUN/STOP
LED flashes yellow. The RUN/STOP LED lit yellow indicates that the CPU has been reset to
the factory settings and is in STOP mode. The "Reset to factory setting" event is entered in
the diagnostics buffer.
