Copying parameter data sets from non-volatile memory to the Memory Card
There are three ways of copying parameter data sets from non-volatile memory (ROM) to the
memory card:
● The system is powered down
● The system is switched on
● The system is switched on
NOTICE
While saving (BOP20 flashes, RDY LED flashes), the device must NOT be switched off.
Switching off the device while saving leads to the loss of the most recently performed and
not yet saved device parameterization.
Note
When options are being used (DCC, SMC30, TM15, TM31, etc.) and with certain device
configurations, the duration of the power-up can take several minutes.
Note
When a memory card is inserted, the RAM to ROM command (p0977 = 1) will copy the
parameter data set with the index 0 from the ROM to the memory card. A parameter data set
that might have been previously saved on the memory card is overwritten.

– Insert a memory card into the CUD
– Switch on the system
– The system is put into operation by the software in the "ROM"
– Then the complete updated parameter data set with the index 0 is automatically
copied from the "ROM" to the Memory Card without a prompt appearing.
– Insert a memory card into the CUD
– Execute the command "RAM to ROM" (p0977 = 1). The updated parameter data set is
copied automatically, first to the "ROM" and then as a data set to the Memory Card
with index 0. If the Memory Card already contains a parameter data set with the index
0, this will be overwritten without a prompt appearing.
– By the user, utilizing the parameter data transfer from ROM to the memory card:
p0804 = 2, p0802 = (0...100) as target on the memory card and p0803 = (0/10/11/12)
as source from the ROM.
