2.2.7. Object 1010h: Store Parameters
This object supports the saving of parameters in non-volatile memory. In order to avoid storage of parameters
by mistake, storage is only executed when a specific signature is written to the appropriate sub-index. The
signature is “save”.
The signature is a 32-bit unsigned number, composed of the ASCII codes of the signature characters,
according to the following table:
MSB LSB
e v a s
65h 76h 61h 73h
On reception of the correct signature to an appropriate sub-index, the 2IN-2OUT-SIG-CO Controller will store
the parameters in non-volatile memory, and then confirm the SDO transmission.
By read access, the object provides information about the module’s saving capabilities. For all sub-indexes,
this value is 1h, indicating that the 2IN-2OUT-SIG-CO Controller saves parameters on command.
This means
that if power is removed before the Store object is written, changes to the Object Dictionary will NOT
have been saved in the non-volatile memory, and will be lost on the next power cycle.
