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
"Delete IP address" deletes all IP addresses, regardless of how you established the
online connection.
If there is a SIMATIC memory card inserted, selecting the "Delete IP address" option has
the following effect:
• The IP addresses are deleted and the CPU is reset to factory settings.
• The configuration (including IP address) on the SIMATIC memory card is then loaded
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. A yellow RUN/STOP LED indicates that the CPU has been reset to
factory settings and is in the STOP operating state. The "Reset to factory settings" event is
entered into the diagnostics buffer.
