Switching Over Interfaces; Memory Reset / Reset To Factory Defaults - Siemens SIMATIC NET CP 442-1 RNA Equipment Manual

Configuration and operation

6.2 Switching over interfaces

6.2 Switching over interfaces
The choice of the interface to be used, RNA interface or Ethernet interface is made in the
configuration of the CP. Each configuration or changeover of the interface therefore requires
that the configuration data is downloaded again.
NOTICE
Interface change - load configuration data only via other module
If you change over the currently active interface and when you load the configuration data,
you will need to use an interface of the CPU or the interface of another CP to load the
configuration data.
If you load the configuration data via the interface of the CP 442-1 RNA, on which the
interface should be switched over, the loading cannot be completed.
6.3

Memory reset / reset to factory defaults

The CP has a twolevel function available for resetting memory:
• Memory reset
• Resetting to factory setting
Note
Data on the CP is deleted - CPU data is retained
The functions for resetting and resetting to factory defaults described here do not change
the configuration data on the CPU! Only the data kept on the CP is deleted.
If you subsequently upload the configuration data from the CPU to a PG you will always
object the configuration data that was previously on the CP (with parameters,
connections, IP address).
Note
Memory reset - ACL (access control list)
After a memory reset on the module, the following applies:
• ACL remains active.
