2.2.8. Object 1011h: Restore Parameters
This object supports the restoring of the default values for the object dictionary in non-volatile memory. In
order to avoid restoring of parameters by mistake, the device restores the defaults only when a specific
signature is written to the appropriate sub-
index. The signature is “load”.
The signature is a 32-bit unsigned number, composed of the ASCII codes of the signature characters,
according to the following table:
MSB
LSB
d
a
o
l
64h
61h
6Fh
6Ch
On reception of the correct signature to an appropriate sub-index, the 2IN-2OUT-SIG-CO Controller will
restore the defaults in non-volatile memory, and then confirm the SDO transmission.
The default values are
set valid only after the device is reset or power-cycled.
This means that the 2IN-2OUT-SIG-CO Controller
will NOT start using the default values right away, but rather continue to run from whatever values were in the
Object Dictionary prior to the restore operation.
By read access, the object provid
es information about the module’s default parameter restoring capabilities.
For all sub-indexes, this value is 1h, indicating that the 2IN-2OUT-SIG-CO Controller restores defaults on
command.
