CO4011A-FL
Single Chip CANopen Controller for Remote I/O
By read access to object 1010h Subindex 1, the
device responds with SDO data 00000001h indi-
cating that storing of data is only done on command.
Note:
Writing to this objected is only allowed in pre-
operational mode.
Index 1011 : Restore Default Parameters
With this object the default values of parameters
according to the communication or device profile are
restored. By read access the device provides infor-
mation about its capabilities to restore these values.
Several parameter groups are distinguished:
Sub-Index 0 contains the largest Sub-Index that is
supported.
Writing to Sub-Index 1 restores all parameters that
can be restored.
In order to avoid the restoring of default parameters
by mistake, restoring is only executed when a
specific signature is written to the appropriate sub-
index. (This means that the signature is transferred
as data bytes 4 to 7 in the CAN message of the
corresponding SDO protocol.
The signature is "load".

On reception of the correct signature on sub-index 1
the device restores the parameters and then
confirms the SDO transmission (initiate download
response). If the storing failed, the device responds
with an abort SDO transfer (abort code: 0606
0000h).
If a wrong signature is written, the device refuses to
store and responds with Abort SDO Transfer
(Abort code: 0800 002x h).
The default values are set valid after the device is
reset (reset node) or power cycled. If the device
requires storing on command (see Object 1010h),
the appropriate command has to be executed after
the reset if the default parameters are to be stored
permanently.
