A comment: The output data quality is determined by LN.Beh, so for steps 7 to 12, when LN.Beh is “test” or “test/blocked”, the DUT will/should/shall(?) publish (the "pong" message) with quality.test=true.

The output data quality is determined by LN.Beh, so for steps 7 to 12, when LN.Beh is “test” or “test/blocked”, the DUT shall publish (the "pong" message) with quality.test=true.

This behaviour is described in Part 7-4, Annex A, Table A.1.

Maybe we need to change the text "DUT ignores the data value changes flagged with quality test true" to something more explicit. The DUT may do something like "blocknig protection function" for sample value case, or be configured in case of GOOSE subscription to replace the incoming value. Ignore is not the correct word for exposing that the DUT acklowedged the presence of the test mismatch and react accordingly to the test mismatch expected behavior.

sSvs16: agree. If the "DUT ignores the test samplesd flagged valueswith quality test true", then its SV subscribing function is not using the samples any more, processing analogues is discontinued. Propose to change into "DUT does not process the test samplesd flagged values with quality test true. An alarm message is created (when supported)." .

sGos23: agree. Propose to change into "DUT does not process the data value changes flagged with quality test true. DUT continues repeating GOOSE with the last values and does not send GOOSE with the changed values." .

Propose to change expected results of sSvs16 into "DUT does not process the test samples flagged values with quality test true. Verify according to PIXIT Svs1a that the samples are NOT consumed.".
Propose to change expected results of sGos23 into "DUT processes the data value flagged with quality test true as described in the PIXIT (for instance: keep last non test value, substitute to a configured value, ...)".
