9.1Memory Reset

Available Functions

The CP has a two-level function available for resetting memory:

SClear / 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

SResetting 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).

How to Use the Function

You can start the memory reset functions in STEP 7.
