Analog Value (AV) Objects
Use the Present_Value property of the Analog_Value object for all writable variables in the meter
other than those used specifically for BACnet configuration, Time Synchronization (in the Device
Object).
Values are checked when written, and errors are returned for invalid entries. This table describes
how the meter uses those variables, what values are valid, and what their defaults are. When
writing values to the Present_Value properties of Analog_Value BACnet objects, there is a delay
of up to about two seconds to validate and store the new value. An immediate read of the same
property before that delay has elapsed can return the prior value (even if the new value was
accepted). To read a value immediately after writing it, check the Reliability property first. When
it reports a No_Fault_Detected status, the Present_Value of the object is current. These objects
