Point types & priority array
Toggle command sources and watch the BACnet priority array resolve which one actually controls the point (life-safety always wins), then classify each point by type.
Interactive DDC lab: a BACnet priority array resolving competing commands to a writable point, plus a point-type classifier.
Priority array — who controls the supply fan?
A writable point obeys the lowest active priority number. Toggle sources and watch the winner.
Effective command:
On
from Schedule (16)
Classify each point
AI = analog in · AO = analog out · BI = binary in · BO = binary out.
