C.7 BACnet Objects Supported
u Present Value Access
The Present Value (PV) of BACnet objects can always 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 C.3 and will be noted for the PV of each object.
Table C.3 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
