Names of DataObject Attributes and SubDataObject Attributes are defined in ISO/IEC IEC 61850-7-3 and the following table contains only the most common ones:
...
For the Structure object type: it is possible to specify the index where IEC 61850 Quality is located. The format of the Quality Index is the same as a complex address.
IEC 61850 Quality is of Bitstring type with a length of 2 bytes. 13 quality bits are defined as follows (the standard numbers the bits so that the highest bit is 0 and the lowest is 15):
