 CEA-709 Mapping Information: This information is derived from the SNVT. It
defines how the NV contents are mapped to the data point.
 NV Scaling A, B, C: These are the scaling factors known from the SNVT table.
The scaling factors are applied to translate a raw NV value into the scalar
representation of the data point.
 Data Type: This is the basic NV data type. This is usually filled in from the
SNVT definition.
 Local NV Member Index: This property specifies the NV member index within
a given functional block. This must be a unique index in the functional block,
which identifies the NV after other NVs have been added or removed from the
interface.
 Local/Remote NV Index: This property specifies the NV index. For local, static
NVs this is the NV index of the static NV. For external NVs, this is the NV index
of the NV on the remote device.
 Local/Remote NV Name: This property specifies the programmatic name of the
NV. For local, static NVs this is the programmatic name of the static NV. For
external NVs, this is the programmatic name of the NV on the remote device.
 Local/Remote Functional Block: This property specifies the functional block
the NV should reside in. For local NVs, one of the available functional blocks
can be selected.
 Local/Remote NV Flags: This property specifies the NV flags. For local (static
or dynamic) NVs, the flags can be configured. For external NVs, these flags are
only informational.
 Remove NV Information: For external NVs, this property contains the
information on the remote device and the NV selector on that device.
 Remote Device ID: For external NVs, this property contains information on the
remote device by listing the program ID and location string.
 Remote Device Address: For external NVs, this property contains the CEA-709
network addressing information to access the node, i.e., subnet, node, and NID.
 Retry Count: For external NVs, this property defines the retry count. The default
is 3.
 Repeat Timer: For external NVs, this property defines the repeat timer in
milliseconds. The default is 96 ms.
 Transmit Timer: For external NVs, this property defines the transmit timer in
milliseconds. The default is 768 ms.
 LNS Network Path: If available from an LNS scan, this property specifies the
LNS network path of the device where the given NV exists.
 LNS Channel Name: If available from an LNS scan, this property specifies the
LNS channel name of the device where the given NV exists.
10.6.5 BACnet Properties
Apart from the common data point properties discussed in Section 10.6.3, data points of the
BACnet technology have additional properties. Depending on whether a server object
and/or a client mapping exists, the properties may vary.
 Engineering Units: For analog BACnet server objects, this property defines the
engineering units from the BACnet standard. One of those units can be chosen
from a drop-down box, if this property is not locked.
 Server Object Type: This property defines the BACnet object type of the
underlying BACnet server object. It can be changed within the class, i.e., for an
