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).
Reset to the 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 switch.
3. Within the next three seconds, return the mode selector to the MRES position, and then
back to STOP.
Result: The CPU executes a 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 settings" event is entered in the
diagnostics buffer.
