12.7.1 Resetting the CPU to factory settings
Introduction
The CPU can be reset to its delivery state using "Reset to factory settings". The function
deletes all information saved internally on the CPU.
If you want to remove a PROFINET CPU and use it elsewhere with a different program, or
put it into storage, we recommend that you reset the CPU to its factory settings. When
restoring the factory settings, remember that you also delete the IP address parameters.
Recommendation
Put the CPU into its delivery state if:
● You remove a CPU and use it elsewhere with a different program
● You return the CPU to stock
When resetting to factory settings, remember that the IP address parameters are also
deleted.
Options for resetting a CPU to factory settings
The following options are available for resetting the CPU to its factory settings:
● Using the mode selector
● Using STEP 7
● Using the SIMATIC Automation Tool
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 (the RUN/STOP LED is lit yellow).
Note
Reset to factory settings ↔ Memory reset
The procedure described below also corresponds to the procedure for a memory reset:
•
Selector operation with inserted SIMATIC memory card: CPU executes a memory reset
•
Selector operation without inserted SIMATIC memory card: CPU executes reset to factory
