9 Further Notes on Operation

9.1 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 default MAC addresses 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

− PROFINET CBA interconnections

S Resetting to factory settings

After the memory reset, the CP retains only the two factory-set MAC addresses

(as shipped).

How to use the function

You can start the memory reset functions in STEP 7.

S Clear / reset

In STEP 7/HW Config with PLC

In STEP 7 / NCM Diagnostics with Operating Mode

Clear/Reset Module

Defaults

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.

if the configuration data are stored on the CPU, you can start a download with

power down/up.
