0x1010 Store parameters

This object shall control the saving of parameters in non-volatile memory.

By read access the CANopen device shall provide information about its saving capabilities. Several parameter groups are distinguished:

• Sub-index 00_h contains the highest sub-index that is supported.
• Sub-index 01_h refers to all parameters that may be stored on the CANopen device.
• Sub-index 02_h refers to communication related parameters (index from 1000_h to 1FFF_h).
• Sub-index 03_h refers to application related parameters (index from 6000_h to 9FFF_h).
• Sub-index from 04_h to 7F_h manufacturers may store their choice of parameters individually.
• Sub-index from 80_h to FE_h are reserved for future use.

In order to avoid storage of parameters by mistake, storage shall be only executed when a specific signature is written to the appropriate sub-index. The signature that shall be written is "save":

Figure 55: Storage write access signature

On reception of the correct signature in the appropriate sub-index the CANopen device shall store the parameter and then it shall confirm the SDO transmission (SDO download initiate response). If the storing failed, the CANopen device shall respond with the SDO abort transfer service (abort code: 0606 0000_h).

If a wrong signature is written, the CANopen device shall refuse to store and it shall respond with the SDO abort transfer service (abort code: 0800 002x_h).

On read access to the appropriate sub-index the CANopen device shall provide information about its storage functionality with the following format:

Structure of read access

Bit	Value	Description
auto	0b 1b	CANopen device does not save parameters autonomously CANopen device saves parameters autonomously
cmd	0b 1b	CANopen device does not save parameters on command CANopen device saves parameters on command

Autonomous saving means that a CANopen device stores the storable parameters in a non-volatile manner without user request.
