Quality information in sampled values streams

Sample quality codes
Sampled values streams contain a "Health" information according to IEC 61850 in order to
indicate the validity of the transmitted information. The quality information contains several
attributes: a general validity code (2 bit), a detail quality code/source and a test (14 bit).
SAM600 uses the quality attributes as described in
Table 2:
Quality attribute
Validity
Detail Quality
Source
Test
The resulting quality of a measured quantity in an IEC/UCA 61850-9-2LE is one out of the two
possible validity values. The other quality attributes can be a combination of the possible
values.
Sample quality indications
If a SAM600 module is configured for sending unmerged sampled value streams to its uplinks,
then the sample quality of the not contained quantity is set to
and the sample quality of the contained quantity is set to
for various conditions are listed in
Table 3:

Invalid | Bad Reference
Invalid | Failure

Merging and bridging of SV streams in a SAM600 system

The configuration of the SAM600 system regarding assignment of streams to access points is
performed with the SV Stream and Port Configuration tool in PCM600 (see Section 3).
