Memory Reset

Available Functions
The CP has a two-level function available for resetting memory:
S Clear / reset
Following this memory reset, the CP retains the preset MAC address and the
retentive parameters. The CP is therefore immediately ready for downloads
using the IP address.
The retentive parameters include:
− IP address, subnet mask and, if applicable, router address
− LAN settings
S Resetting to factory settings
After this memory reset, the CP retains only the factory-set MAC address (as
shipped).
Note
Using the functions described here to reset the memory, you do not modify the
configuration data on the CPU!
If you subsequently upload the configuration data from the CPU to a PG you will
always obtain the configuration data that were previously on the CP (with
parameters, connections, IP address).

You can start the memory reset functions in STEP 7.
