Note
It is recommended that SIMOTION SCOUT be used exclusively to switch the operating 
modes 
of the module. Therefore, leave the mode switch at position 0 (RUN). The LED display 
indicates the current mode selection. 
For information on how to set the operating mode using SIMOTION SCOUT, see the 
SIMOTION SCOUT
 Configuration Manual.
 
Service selector switch (V4.1 SP2 and higher)   
The following table shows the possible positions of the Service selector switch. The Service 
selector switch positions are explained in the order in which they are arranged on the 
SIMOTION D4x5.

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 
upgrade data is generated with the device update tool (Menu: 
"Project>Start device update tool" in SIMOTION SCOUT).
If the upgrade process fails to bring about the desired result, 
the upgrade 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 state is the availability of enhanced diagnostic 
information (via websites) and TO alarm information.
