*CANopen SDO buffer size*

Type: ``int``

Help
====

Size of the internal CANopen SDO buffer in bytes. Size must
be at least equal to the size of the largest variable in the
object dictionary. If data type is DOMAIN, data length is
not limited to the SDO buffer size. If block transfer is
implemented, value should be set to 889.
