Procedure using the display
Make sure that the CPU is in STOP mode (CPU shows STOP mode or RUN/STOP LED
lights up yellow).
To navigate to the desired "Factory settings" menu command, select the following sequence
of menu commands and confirm after each selection with "OK".
●
Settings
→ Reset → Factory settings
Result: The CPU executes a "Reset to factory settings", during which time the RUN/STOP
LED flashes yellow. When the RUN/STOP LED lights up yellow, then the CPU has been
reset to factory settings, and is in the STOP mode. The "Reset to factory settings" event is
entered into the diagnostics buffer.
Note
The IP address of the CPU is also deleted when the CPU is reset to the factory settings
through the display.
Procedure using STEP 7
To reset a CPU to factory settings via STEP 7, follow these steps:
Make sure that there is an online connection to the CPU.
1.
Open the Online and Diagnostics view of the CPU.
2.
In the "Functions" folder, select the "Reset to factory settings" group.
3.
If you want to keep the IP address, select the "Keep IP address" option button. If you
want to delete the IP address, select the "Delete IP address" option button.
Note
The "Delete IP address" deletes all IP addresses. This applies regardless of how you
established the online connection.
If a SIMATIC memory card is inserted, the "Delete IP address" option deletes the IP
addresses and resets the CPU to factory settings. Then, the configuration (including IP
address) that is stored on the SIMATIC memory card is transferred to the CPU (see
below). If you formatted the memory card before the reset to factory settings or if the
memory card is empty, no IP address is transferred to the CPU.
4.
Click the "Reset" button.
5.
Click "OK" in response to the confirmation prompts.
Result: The CPU executes a "Reset to factory settings", during which time the RUN/STOP
LED flashes yellow. When the RUN/STOP LED lights up yellow, then the CPU has been
reset to factory settings, and is in the STOP mode. The "Reset to factory settings" event is
entered into the diagnostics buffer.
