Issue

Measurements reporting is usually controlled by deadbands to trigger on dchg. Nevertheless, users want to see the precise values (not exceeding deadband thresholds) after a certain time using integrity reports.

Is it allowed for an integrity report to transmit the exact measurement values measured at the time of the report creation or is it mandatory to re-send the values of the last spontaneous report sent on dchg (respecting deadband thresholds)?

The similar behaviour to be considered for general interrogations.

Proposal

Integrity reporting uses the exact measurement values measured at the time of the report creation. These values are furthermore used as the evaluation basis for the next spontaneous report sent on dchg (deadband threshold transition). Reason for inclusion (if set to TRUE in OptFlds) shall be "integrity" only.
