Delete/restore 
non-volatile data 
1  When the "Delete/restore non-volatile data" switch setting is 
selected, the non-volatile data of the D4x5 is first deleted and 
then restored along with the contents of the PMEMORY 
backup file. 
Downgrade 
(device update 
tool) 
B  SIMOTION D4x5 Control Units and projects can be updated 
using update data created at an earlier point in time. This 
update data is generated with the device update tool (Menu: 
"Project>Start device update tool" in SIMOTION SCOUT). 
If the updating process fails to bring about the desired result, 
the update can be rejected by means of the switch position. 
This will roll the system back to the previous configuration. 
Backing up 
diagnostic data 
and non-volatile 
data 
D  The diagnostic data and non-volatile data can be backed up in 
STOP, STOPU, and RUN modes. The advantage of backing 
up in RUN mode is the availability of enhanced diagnostic 
information (via websites) and TO alarm information.
