Procedure using the mode selector keys (standard, F-CPUs / compact CPUs from article number
6ES751x-xxx02-0AB0/6ES751x-1CK01-0AB0)
Make sure that the CPU is in STOP mode (the CPU display shows STOP mode or
RUN/STOP LED lights up yellow).
Note
Reset to factory settings ↔ Memory reset
The procedure described below also corresponds to the procedure for a memory reset:
•
Key operation with inserted SIMATIC memory card: CPU executes a memory reset
•
Key operation without inserted SIMATIC memory card: CPU executes reset to factory
settings
Perform a reset to factory settings as follows:
1.
Press the STOP mode selector key.
Result: The STOP-ACTIVE and RUN/STOP LED light up yellow.
2.
Keep the STOP mode selector key pressed until the RUN/STOP LED lights up for the
2nd time and remains continuously lit (this takes three seconds). After this, release the
key.
3.
Press the STOP mode selector key again within the next three seconds.
Result: The CPU executes a "Reset to factory settings", during which time the RUN/STOP
LED flashes yellow. When the STOP-ACTIVE and RUN/STOP LED light 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
using the mode selector keys.
