MAESTRO — Automation Interface Protocol Technical Reference Manual
Section 6 — Examples
mere fact that a TX_STAT containing “quiescent” was received via auto-update indicates that the transition state has
changed and that the TX_TRIG is now complete. In the case of very short duration transitions, all transition states will not
necessarily be reported due to other system tasks of higher priority delaying auto-update message formation until after the
state has again changed. But, it is guaranteed that at least one auto-update TX_STAT will be reported for every TX_TRIG
to indicate a change of transition status. If only one auto-update TX_STAT is reported, it will indicate “quiescent” mean-
ing TX_TRIG complete.
