Read Property Function
In the Read Property function, the MICRO/I returns the value of a property when there is a read property request
from a BACnet device. This function is implemented using DS-RP-B (Data Sharing Read Property B) and DS-RPM-B
(Data Sharing Read Property Multiple B).
The below diagram shows a BACnet device reading the analog input value of the MICRO/I that has been associated
with the Analog Input object.
Write Property Function
In the Write Property function, the MICRO/I writes a value to the property of an object when there is a write property
request from a BACnet device. This function is implemented using DS-WP-B (Data Sharing Write Property B) and DS-
WPM-B (Data Sharing Read Property Multiple B).
The below diagram shows a BACnet device changing the analog output value of the MICRO/I that has been
associated with the Analog Output object.
