Alternatively, you can back up parameter sets without switching the CU305 off/on as follows:
● The system is switched on:
– Insert a memory card into the CU305.
– Execute command "RAM to ROM" (p0977 = 1). The up-to-date parameter data set is
copied automatically, first to the "ROM" and then to the memory card (in the latter
case as a data set with the index 0). If the memory card already contains a parameter
data set with the index 0, this will be overwritten without a prompt appearing.
● The system is switched on:
The user starts data transmission from the ROM to the memory card with parameters
p0802, p0803 and p0804:
– p0802 = (0...100) as target (to the memory card), p0803 = (0/10/11/12) as source
(from the "ROM"), and p0804 = 1.
Note
RAM to ROM transfer will overwrite the content of an inserted memory card.
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. Any parameter
data set previously saved to index 0 will be overwritten.
Series commissioning (copying parameter sets)
There are several ways of copying parameter data sets from the memory card to non-volatile
memory:
CAUTION
The parameter data set in the "ROM" is overwritten during system start-up.
Parameters already backed up to the CU305 with the setting 0 will be overwritten during the
following process!
