Operation
9.1 Basic information
● The system is switched on
– By the user, utilizing the parameter data transfer from ROM to the memory card:
Note
If when switching on, a memory card with a parameter data set with index 0 is inserted in the
CUD, the parameter data set with index 0 in the non-volatile memory of the CUD is
overwritten with the parameter data set with index 0 on the memory card.
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.
Note
While saving (BOP20 flashes, RDY LED flashes), the electronic power supply must NOT be
switched off. Switching off 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, TM150, etc.) and with certain
device configurations, the duration of the power-up can take several minutes.
Copying parameter data sets from the memory card to non-volatile memory
There are two ways of copying parameter data sets from the memory card to non-volatile
memory:
● The system is powered down
– Insert a memory card containing a parameter data set with the index 0 into the CUD.
– Switch on the system. The new parameter data set will be copied to the ROM
– The system will then boot with the new parameter data set.
● The system is switched on
The user starts data transmission from the memory card to the ROM with parameters
p0802, p0803 and p0804:
– p0804 = 1
– p0802 = (0...100) as source from the memory card and p0803 = (0/10/11/12) as target
336
p0804 = 2, p0802 = (0...100) as target on the memory card and p0803 = (0/10/11/12)
as source from the ROM.
automatically. The parameter data set with the index 0 which was previously in the
ROM will be overwritten.
