Clear/reset module - effects
After resetting memory, the CP retains the configured MAC address, the IP address and the
retentive parameters (for information on the retentive parameters, refer to section CPLUG
(configuration plug) (Page 60)). The CP is therefore immediately ready for downloads using
the IP address.
The configuration data is retained on the CPU.
