Command processing order and error response

Check whether each ID is within the supported range in the following order:

Supplement for object processing

• Get_Attribute_Single and Get_Attributes_All are executed, ignoring send service

data.

• The service (Get_Attributes_All, Reset) that does not designate an attribute ID is

executed, ignoring attribute ID.

• If Set_Attribute_Single is designated for an attribute which cannot be written (Set),

"0EH" (Attribute not settable) is returned as the general status.

• If Set_Attribute_Single for the writable attribute is designated and the writing size

is less than the attribute size, the general status "13H" (Not enough data) is
returned. If the writing size is greater than the attribute size, the service is
executed, ignoring the excessive data.
