SDO abort code
Last Updated 3 months ago

The CiA Draft Standard 301 (also known as DS301) defines 29 abort codes
Abort CodeDesription
0503 0000hToggle bit not alternated.
0504 0000hSDO protocol timed out.
0504 0001hClient/server command specifier not valid or unknown.
0504 0002hInvalid block size (block mode only).
0504 0003hInvalid sequence number (block mode only).
0504 0004h CRC error (block mode only).
0504 0005h Out of memory.
0601 0000h Unsupported access to an object.
0601 0001h Attempt to read a write only object.
0601 0002hAttempt to write a read only object.
0602 0000hObject does not exist in the object dictionary.
0604 0041h Object cannot be mapped to the PDO.
0604 0042h The number and length of the objects to be mapped would exceed PDO length.
0604 0043h General parameter incompatibility reason.
0604 0047h General internal incompatibility in the device.
0606 0000h Access failed due to a hardware error.
0607 0010h Data type does not match; length of service parameter does not match.
0607 0012h Data type does not match; length of service parameter too high.
0607 0013h Data type does not match; length of service parameter too low.
0609 0011h Sub-index does not exist.
0609 0030h Value range of parameter exceeded (only for write access).
0609 0031hValue of parameter written too high.
0609 0032hValue of parameter written too low.
0609 0036hMaximum value is less than minimum value.
0800 0000hGeneral error.
0800 0020hData cannot be transferred or stored to the application.
0800 0021hData cannot be transferred or stored to the application because of local control.
0800 0022hData cannot be transferred or stored to the application because of the present device state.
0800 0023hObject dictionary dynamic generation fails or no object dictionary is present
(e.g. object dictionary is generated from file and generation fails because of a file error).
you should interprete the CAN message with a little-endian ordering which places the least significant byte first and the most significant byte last.
e.g.
The last 4 bytes message 00 00 02 06 is actually 0602 0000h, which means "Object does not exist in the object dictionary".
