10 Further Notes on Operation
10.1
Memory Reset / Resetting the to the Factory Settings
The CP has a two-level function available for resetting memory:
S
Clear / reset
S
Resetting to factory settings
Notice
With the functions for memory reset and resetting to the factory settings described
here, the configuration data on the CPU is not changed! Only the data maintained
on the CP (C-PLUG and RAM areas) is deleted.
If you subsequently upload the configuration data from the CPU to a PG you will
always object the configuration data that were previously on the CP (with
parameters, connections, IP address).
How to Use the Functions
You can start the memory reset functions in STEP 7. The CP must be in STOP. If
you use PROFINET IO, the CPU must also be in STOP mode.

Behavior after Memory Reset
The CPU in the S7 station does not recognize that the CP memory was reset. The
CP therefore changes to the “stopped with error” state (see Chapter 4).
The configuration data must then be reloaded. You can initiate this loading by
turning the power off and on again.
