3.1.6. Object 1011h: Restore Default 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 subindex. 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 subindex, the 18 Digital Input will
restore the defaults in non-volatile memory, and then confirm the SDO transmission. The
default values are set valid after the device is reset or power-cycled.
By read access, the object provides information about the module’s default parameter
restoring capabilities.
