u Present Value Access
The Present Value (PV) of BACnet objects can be read. In addition, some PVs can be written
or commanded. A commandable PV is similar to writing the value, but the value is actually
written into a priority array. The value occupying the highest priority in the array will be used
by the drive. The convention for showing how the PV is accessed is shown in Table 10 and
will be noted for the PV of each object.
Table 10 Present Value Access Values
PV Access Name Description
C Commandable
Value written to a priority array. The highest priority value in the array is then
written to the drive.
R Readable Value is read-only
W Writable Value written to the drive
