7.7 Object 2007h: Save_Parameter
This object supports the saving of parameters in non volatile memory (EEPROM). By
read access the measuring system provides information about its saving capabilities.

In order to avoid storage of parameters by mistake, storage is only executed when a
specific signature is written. T
he signature is “save”.
Signature
MSB

ISO 8859, ASCII

On reception of the correct signature the measuring system stores the parameter and
then confirms the SDO transmission. If the storing fails, the measuring system
responds with an Abort SDO Transfer.
If a wrong signature is written, the measuring system refuses to store it and responds
also with an Abort SDO Transfer.
On read access the measuring system provides information about its storage
functionality:

Auto:
0 = Parameters are not stored automatically
1 = Parameters are stored automatically
Cmd:
0 = Parameters are not stored on command
1 = Parameters are stored on command
Autonomous saving means that the measuring system stores the storable parameters
in a non-volatile memory without user request.
